Good vehicle. I have Avalon hybrid, love it. Big car at 40 mpg. Toyota make best hybrids. This little thing had 5gallons that filled tank at almost half. People should start buying this kind of vehicles. Maybe we will be semi independent on fuel sometime. Toyota- good job!!!
Juan Velez: It’s runs only for 3 miles before ICE kicks in, but charges battery fast. Also it has Atkinson cycle engine. You would get better MPGs on those engines. I would go about 540-560 miles on about 12-13 gallons.
I have a 2004 (Gen II) Prius with ~170K miles on it, & the original traction battery. I don't know why it would be that much different than a Prius C aside from being a bit heavier. I've never run out of fuel as I don't care to chance the cost of (expensive?) repairs. I practice in seeing how long my Prius will go, in electric-only mode, as an exercise to maximize mileage. Of course, I turn off heavy-electric items, such as the air conditioning (this includes while in the usual/normal hybrid mode). I live in a relatively flat area, nothing more severe than an occasional very mild grade. I always get a few miles in electric-only mode (never took any serious measurements nor kept any record). On a flat surface, I can get to 40 mph before the IC engine cuts in. In the usual hybrid mode, on several occasions, I've gotten ~72 mpg. On a recent trip from the northern area of the state to the southern area, ~100 miles, I got 63 mpg. In that 170K miles I've only had 1 repair that wouldn't be something considered the usual maintenance, & that was the IC engine coolant circulation pump; for me, it was ~$350, parts & labor at the dealer. Original exhaust, original brakes. My opinion, the Toyota Prius is the best car, hands-down, that I've ever owned (& I'm 60 years old & a professional driver) & when it comes time to buy another, it'll be another Prius, or a variant. Wish it came with the rear-view camera back then... & my only complaint is the brake-turn-backup light assembly. The LED brake lights do fail after a time (mine lasted 13 years) & those can't be replaced unless one cares to do some cutting & dissecting of the LED light assembly (it's plastic-welded together). I found comparable aftermarket & replaced them myself. I also wish the fuel tank was larger, & that I knew of the plug-in variant, if it was even available in 2004. All in all, excellent engineering job, Toyota!
The Gen 3 Prius gives the low gas warning when you reach the last 50 miles of “projection to empty.” Based on how much gas goes in even after reaching zero and the total capacity of the tank. Toyota seems to factor in 1.5 gallons to compensate for human stupidity.
That’s gels with my experience. I thought I was literally at zero. Bolted to the closest gas station than I filled it up…and I actually had 1.8 gallons in the tank.
I have a C-HR 1.8 Hybrid. While driving 640 kms on the motorway (with cruise control set at 110kph, averaging 5.9 l/100) the light came on with about 44 KMs to go of fuel. At - - - on the display I filled up with Petrol. The tank is supposed to take 43 Litres. I filled up with 37.51 litres. Which means that with the 5.5 litres in the left in the tank I should have had at least another 100 kms to drive (if I continued on the motorway with no battery use). So, the light is extremely optimistic. But it still makes me panic!
Hahahaha 🤣 ... Well said ... that is a fantastic way of putting it and I guess you are correct here. With zero miles to go you still have 1.5 gallons of gas left in your tanks. If you still don't get your car to the gas station fast ... you definitely are stupid.
Just an addition, If your prius runs out of battery and gas, you charge it or get it gas and it still has some battery left but won't start after adding gas. The computer needs a reboot and the easiest way to do this is to simply disconnect and reconnect the 12v battery in the rear passenger side of the vehicle.
Very helpful video, my prius fuel indicator is faulty. The car stopped and steering wheel blocked. I had refueled 2 days before and wasn't expecting that the car ran out of gas.

First off, Kudos for doing the 'forbidden experiment'. I've done similar experiments with the 2003, 2010, and 2017 Prius Prime. The 2003 typically went 60-70 miles, 1.2 gal., and the 2010 would go ~120 miles, 2.1 gal., on 'low fuel' warning before the engine stopped. Then use the traction battery to find a safe place to park and refuel. Using a 1 gal spare can, I had no problem starting the 2003 and 2010 although the low fuel warning requires more than a gallon to turn it off. The 2003 lit up the dash when the gas was finally gone but the 2010 power-flow indicator was the only way to tell that the gas was finally out. There were credible reports that after three failed restart events, a flag is set that requires either a dealer tow or power-on, reset of the 12V by disconnecting and reconnecting the 12V ground. That was the default with our Prius Prime as I had no indication when the last of the gas was gone. The Prius Prime just set the 'power steering' fault and with no motive power, I had to coast into a parking lot. After adding a gallon, the Prime would not start but a 12V, power-on restart worked perfectly.
rashamekia Hunter, no. Just turn your car off, fill up, and start normally. One of the users mentioned if you try to restart with the power button more than 3 times, it trips some sort of code that i do not know about.
Owners beware, I ran out of gas in my 07 Prius & used battery to try to make it to a fuel station. Consequently I ran out of battery not 50 yards shy. After adding gas, I pushed the power button on/off sev times trying to prime the fuel pump & it caused a complete shut down or "tripped" a protective electronic shut down feature that u refer to. Had to have the car towed to Toyota service center where they charged me $330 to test, reset & charge the hybrid battery back into a functional state. You sir, should consider yourself lucky u didn't push that power button 2 more times...
so basically the batteries really dont help without the motor actually running , good to know , i wont buy any car like this due to the fact that i would want to go at least 40 miles at 100 kph on battery alone ..
It was strange it was so flawless. The manual shows that the OSD would warn to stop the vehicle to avoid damage and is supposed to tell the driver to wait until 2 bars show on battery before driving.
Great Vid man, I have the same C model and always wanted to push it when the gas light came on. I thought maybe 35 miles of reserve, but was I wrong. 70 miles on the gas reminder is solid. The C is a beast, it definitely has won me over with fuel and it has enough power when you need it. The only really con is jot enough juice when going up a hill for a long period of time.
And presumably, by the same token, not enough traction battery space to store all of the braking energy on a long steep downhill stretch. I guess it's a compromise (don't want to cart around a very heavy battery all of the time).
Very informative video! Would you tell us if to run out of gas can cause Toyota Prius to stuck in Neutral mode, car engine sound goes off and shift in gears also stuck! Thank you
Cool Video! Amazing to know that I can stretch My prius a bit further. And I have always wondered what will happen if I eventually run out fuel one day.
Not a good idea at all purposely running any car out of gas. The fuel pump in the gas tank relies heavily upon the surrounding gas to keep the fuel pump cool. On some vehicles, if ran low or out of gas, this will throw off the fuel gage reading or worst yet you will have to take the vehicle in to have the gas gage recalibrated.
Same deal for my 2011 Auris hybrid, it also has the Prius gen3 1.8L driveline. It has been incredibly reliable. (In fact the most reliable car i have ever owned, this includes bmw's, volvo's, a saab, a range rover) In all the years i have owned it it only gave me 2 problems: 1x empty keyfob battery warning on the dash + 1x worn out 12v battery. This nearly got me stranded but i was able to get a jumpstart from a friend's motorcycle battery. That way the management electronics of the car were able to boot up after which the traction battery was able to start the engine and drive home without any problem. Bought a new 12V battery and installed it myself. Problem fixed. Whenever the fueltank empty idiotlight starts blinking the car can still cruise 100km/60ish miles at 60mph. I never pushed it though. But it is good to know how the car will react when running out of fuel.
For my 2013 Prius plug-in I got over 100 miles after low gas (the last gas bar blinking fast) and car keeps beeping randomly to make you look. It was 2.1 gallon left in tank. Plus I ALMOST drained the battery. You can't go over 40 in this state, even though you normally go 60ish on plug-in battery. I filled about 11 gallons from empty.
Amazing how clever the engineers were behind this design. It seems unlikely this fella realizes that MG1 will require a certain residual Traction (HV) battery capacity to rotate the engine to start it…To say nothing of the Aux battery having the remaining capacity to close the MSR’s. If I am mistaken, apologies in advance.
Very informative! I bought a 2015 Prius C One just like this one a couple months ago, and I've been filling up as soon as my cruising range hit zero every time. Good to know I can safely stretch it a little bit further if necessary!

V. Useful! So after fuel gone 2-3 miles is the answer and around 35mph. You'll get stranded if the 12v battery dies, for example sitting in the parked car, no idling, AC on. As one does in the summer. For that a little jumpstarter Li battery is sufficient.
My 2012 prius C ran out of gas and battery. I added more gas and it still will not start. I unplugged the Hybrid battery and have left it on the side of the road. I hope it will start up when I get back to it this afternoon after work.
Yo, what year is that prius? I don't know they ever have the info cluster like that... I bet it's a custom third party one? How did you install it? How much did it cost?
Correct but there’s more to it. Mine stopped, got the check hybrid system warning. Had to put in 4 gallons, unplug the 12v battery for 10 min, then start the car. All errors are off, engine runs now. I didn’t get a low fuel warning.
Frankly, you got lucky. Prior gens of Prius would throw a code if it ran out of power and gas. That results in a tow to Toyota to have the code reset. You can’t/couldn’t just add gas and go.
The prius has no electric starter on the engine. It uses the traction battery and MG1 (the generator) to start the engine. If you run it out of gas and if the traction battery gets low enough it won't be able to start and you can't charge the battery. You will be truly up the creek. Not many places have the equipment needed to charge a prius high voltage battery to get the car running again. Most dealers don't have this equipment.
You cannot run down the traction battery on ANY electric vehicle. The cars are programmed to stop running before fully discharged. I have 3 prius, a volt, and an electric Smart. We just drive them. No worries. I ran out of fuel in the desert and limped into town. My brother accused me of trying to wean it off of gas.
It may be a rare thing, but it certainly isn't impossible or they wouldn't make the service equipment to charge the batteries. Leave your vehicle sitting long enough with a discharged battery, and it'll go completely flat all by itself.
I have an old ex-taxi Prius and if I leave it sitting for a week, the traction battery shows up as flat and sometimes I get really poor acceleration until the battery has had a few minutes to charge. It wouldn't surprise me if I left the car sitting for two weeks that it wouldn't have enough juice to start the engine. However I do have an old computer UPS that runs off 200 VDC (16 SLA batteries in series) so I guess I could always hook that up to put a little charge back into the batteries, or even hook up that battery pack in parallel with the car's just to start the engine the first time.
if you keep turning it off and on again and it try´s to start the engine it kan drain the hybrid battery, like they say, the charging equipment is rare. in Holland we only have 1 charger for the hole county...
This is correct. Continually attempting to start the engine will run the traction battery down to a point it can no longer crank the engine. If this happens you will most likely need to find a specialist to preform a rescue charge. Most of the time the dealers can’t even do this and they will recommend replacing the battery. I have seen this happen a handful of times.
I've run out of gas twice on my Prius while trying to push it to the limits on fuel capacity. I was able to get to a gas station both times to get gas. Although I have several other large cars, I still enjoy the little car...I wouldn't advise doing this though as you could do damage to the motor over time.
All the people hating have either not understood the definition of 'Hybrid' and the insane payoff it gives, or have never driven a Prius. Thumbs up from me, cool vid.
Also all you Prius video makers need your video title to state year and generation and model (C, V, Touring, Prime, etc). Your results do not apply to all Prius types. Just saying.
Sagan Android hey, pretty sure he's driving a prius c in the video. Can tell by looking at the displays. Also, note the orange running along the length of the top half of the door.
I agree he should have added year and make but you know a lot about it just looking at the dash. He even showed us the back giving it away that it was a C.
Awesome video thank you my battery went out on my 2012 Prius I drove it with no Hybrid battery for one week average 28 MPG the engine just stayed on continuously Toyota said it's okay I put a new Hybrid battery in it and the average back to 52 MPG
I've had both 2008 Prius and 2013 Prius V. Both were able to run a good few miles after the low fuel warning light came on. But I love my cars too much and rarely go below the light.
On some vehicles, if ran low or out of gas, this will throw off the fuel gage reading or worst yet you will have to take the vehicle in to have the gas gage recalibrated.
Thanks Jo-Check my 2013 Prius ran out of gas and Battery today. Tow driver brought gas but car didn't Restart. Had car towed home, it's Sunday. However I don't think that was a full 5 gallons and the Light still blinked after gas was in the car. My question is: Will I be in trouble if I tell Toyota what happened? If the whole battery needs to be replaced., If the car doesn't eventually start after I add more gas. I truly think the Tow driver didn't bring enough gas. All the Electronics are working Just that the ready light won't come on. I didn't know I was out of Gas.
Hi JO-Check Im owner too of prius c 2014 Im from Latinoamerica Paraguay, as I saw with ODBII connector the SoC of the battery is from 40% to top 70 % according to my calcutaion is about 500Wh only
My 2007 gen 2 in Australia has an EV button...Can run ev mode for around 1 km if under 45km/h (approx)...By the way it still gets after 10 years 4.5 litres per 100km's which in miles is 63 mpg
Similar for me, only my battery is worn out (ex-taxi) so the EV button only gets me 50 metres, or maybe 100 if I've just done a lot of regen braking! I have wondered whether replacing the battery would increase fuel efficiency but I'm still getting 1000km per tank and I find that pretty impressive.
We have a 2016 Prius C and when the distance estimation remaining hits anywhere near 10 miles left my wife starts to get really nervous. I know that at 0 there are still several miles left with gas and more remaining with the battery cell. Still she gets mad at me. :)
I've done this by sitting in the car, parked,no idling, with AC on. Car could not start. But a simple little portable jumpstarter takes care of that easily.
This video in my opinion, proves that Hybrids do make sense especially around town. I believe he would have gotten more than the 1.4 miles with the A/C off and sitting in city traffic.
Perhaps it needs an emergency diesel generator. Take a hint from ships at sea. Or you could have a foldable windmill generator and/or solar cell panels.
The problem with owning a Prius is you start getting over conscious on the MPG meter. I covered mine and check it only once in a week. I am getting 50mpg average.
Cool video, (except music, I really hate music in these videos). You aren't ever supposed to let gas completely drain from the gas tank, but for the sake of information of "just knowing" this real-time knowledge of information is well worth it!! One time, should not do any damage, and those parts need changed eventually anyhow, in the Prius probably every 400,000 miles! LOL. Great video!!
frequent fuel voids on 2nd generation prius is a good way to ruin the traction battery. if it's an old battery the sudden loss of synergy places power load on t.b. causing some of the individual cells to "pop."
Don't forget gasoline changes volume, with changes in temperature. A gallon @66 degrees weights more than a gallon @76 degrees. In America the tax only calculates to a even number if you buy ten gallons like the man from Texas.
At 5:50, the hybrid system cuts out when normally at this point, the fuel engine would turn on to prevent further discharge. The big READY light next to the fuel gauge turned off to indicate this... So from that point on, you are coasting :) Power steering will still work on the normal 12V battery, but will not work optimally because there is no power left. This is quite a lame test, because Toyota has figured this out beforehand of course and you should have read in the manual about the READY light.
@@aprilkolwey4779 so in an experiment where the Prius was first made to run out of gas and subsequently made to run on ev mode till the hybrid battery drained and the car stalled ... It should not be possible to start the Prius again. Yet in all such experiments people just filled up the car with gas and we're able to start the car ... How did that happen. I am just not able to understand. Could you explain this?
@@sanjaykumarsingh1970 I'm not entirely sure, but my best guess is that the car prevents you from draining the battery fully (maybe only down to about 5% left?) so that it still has some power to start the engine after more fuel is added.
@@aprilkolwey4779 Thanks for taking the time to reply .... wow that actually sounds like a very logical answer and would be a very smart and prudent thing to plan for ... Toyota engineering team has done a fine job here but that brings me further to another question. There will be a day when your hybrid battery conks out and your prius refuses to start. I have heard that this error can be bypassed and your hybrid can run purely on gas. Granted that the mileage will now be poor but it will start. What do you think is starting the engine.? My best guess is it's still the hybrid battery. It will work in the interim to start the car but not use the traction motor. Rest of the functions like charging of the hybrid battery etc is still maintained by the car electronics. What do you think? Sorry I am asking you these questions as I purchased an old Prius ... A 2010 model. It's done 160k miles and still runs fine but someday the inevitable will happen and I should know how to get myself out of a sticky situation like this. Thanks.
Nor auto here in france is useless they have no good staff personnel when the filter of my car suddenly remove all the oil came out until its empty but the car still working and it didnt overheat good thing about hybrid car but i dont know if it will last long. today its almost 4 month using my car still no problem
I ran my 2008 out gas 3 times & had no problems what so ever.. I have 185,000 miles on it now. The piston rings are shot. Other than that, she still runs great. Putting a qt of oil in every 1,000 miles until she dies. Hoping for 200,000!
Clean your p c v valve if it’s plugged it pushes oil out because your inside of your engine isn’t breathing 😮💨 those engines run forever 300k unless you drove with no oil. Put motorkote in your engine for extra protection.
Hey that's a great video I was always wondering what would happen with my Prius V if I let it run out of gas. Funny thing after liking this video my Prius V absolutely refuses to let me in. Only my wife can get in that car now!
I know this isnt what this video is about but how slugglish does the car feel (with gas and battery lmao)? I current have a 2001 Corolla with a 4 speed that is decent when floored but horrible at any other time
The Rusty Scooter Its no race car... lol It gets to 80mph on a freeway ok and holds it. Takes a while to get use to a hybrid but if your going for good fuel economy then get one. Go by a dealership and take one for a test drive.
Yea im use to my Corolla and my moms 2015 with a CVT so neither one are mind blowing 0-60 but that doesnt stop me from keeping up with 80-85 mph traffic. I was looking between a gen 2 (2007-2009) or a C because of how cheap they have become. I was also wondering how easy it is for DIY work? I know they are bulletproof but how easy it it to change out a strut or something for example?
The Rusty Scooter if you are looking for a Prius I don’t recommend the C it’s really compact if you are planning on tweaking it. Just go for the regular and up.
I like the regular Prius it just seemed that in terms of "driving enjoyment" (Im fully aware its a Prius so its not a drivers car) the C overall is tighter in the corners, has better steering and a better chassis versus the liftback
Prius in general are sluggish. If you want a fast car that is a hybrid get a Chevy Volt which is about as good as you can get without going full EV. [do not bring up 918 spyder...]
Some cars are worse about burning up fuel pumps from low fuel than others. I know GM vehicles burn up fuel pumps quite easily if you let the tank get less than 1/4 filled.
It's not just that he could be damaging.. the hybrid battery controller, despite showing zero-full charge in the dashboard, does actually always keep the battery between 40-80% (approximate numbers) off actual charge. This is done to prevent overcharging or depletion as that can reduce the life of the battery or even damage individual cells. So, in normal circumstances the engine can always turn on and charge the batteries to ensure their charge never goes below 40%. However, when the engine doesn't start anymore (no fuel for example) then the hybrid battery controller cuts off energy to the traction motor to prevent the batteries going under 40%, but I believe AC and other things running from HV are allowed to run. If one continues with AC on I believe eventually the battery will eventually near depletion and cut off (low voltage threshold). If you arrive to this point, it's quite possible you damage some cells as they never share the same wear/voltage...
+No: I don't know of any that cut off the fuel pump until the engine has been off for the length of time that is programmed into it. Lots of fuel pumps die this way, partly because it is also cooled by the fuel. In Mesa, Arizona, shop owner Mark Salem once remarked on his radio show that nearly all the fuel pumps he replaced were for college students who kept their tanks nearly empty.
All this needs is the title changed to 'Prius *C* runs out of gas and battery power'.
My Prius manual absolutely warns against letting the car run out of gas.
Turn AC and HID lights off and you could have went MUCH further.
HID lights use very little power after the first 20-ish seconds of startup, they actually use less power than halogens
Good vehicle. I have Avalon hybrid, love it. Big car at 40 mpg. Toyota make best hybrids. This little thing had 5gallons that filled tank at almost half. People should start buying this kind of vehicles. Maybe we will be semi independent on fuel sometime. Toyota- good job!!!
Hi Albert, one question. Can you drive your hybrid on electricity without the engine turning on?
Juan Velez: It’s runs only for 3 miles before ICE kicks in, but charges battery fast. Also it has Atkinson cycle engine. You would get better MPGs on those engines. I would go about 540-560 miles on about 12-13 gallons.
That's awesome. My Cruze diesel gets about 550 miles on 13 gallons also.
Very cool! That was a lot calmer than I expected.
Can't hear engine struggles over stupid music.

You are a hero.LOL I just bought a used Prius 2 weeks ago.Today I found out a little leaking from the bottom but no lights on.I am really scary now.
Wow ! That's crazy, amazing video man!
I was wondering about this today. Thanks for your sacrifice..
You are pretty smart. Salute to this great information. I don't care model as far as I know about 50 to 60 miles on Prius.
It was strange it was so flawless. The manual shows that the OSD would warn to stop the vehicle to avoid damage and is supposed to tell the driver to wait until 2 bars show on battery before driving.
I have Prius. I enjoy watching this experiment.
Thank you so much. Very helpful.
Great Vid man, I have the same C model and always wanted to push it when the gas light came on. I thought maybe 35 miles of reserve, but was I wrong. 70 miles on the gas reminder is solid. The C is a beast, it definitely has won me over with fuel and it has enough power when you need it. The only really con is jot enough juice when going up a hill for a long period of time.
And presumably, by the same token, not enough traction battery space to store all of the braking energy on a long steep downhill stretch.
I guess it's a compromise (don't want to cart around a very heavy battery all of the time).
Very informative video! Would you tell us if to run out of gas can cause Toyota Prius to stuck in Neutral mode, car engine sound goes off and shift in gears also stuck!
Thank you
Prius:I suggest you always fill up on the light
very cool experiment & thx... now I know but how far could it have gone with the A/C off and lightly driven?
Cool Video! Amazing to know that I can stretch My prius a bit further. And I have always wondered what will happen if I eventually run out fuel one day.
Not a good idea at all purposely running any car out of gas. The fuel pump in the gas tank relies heavily upon the surrounding gas to keep the fuel pump cool. On some vehicles, if ran low or out of gas, this will throw off the fuel gage reading or worst yet you will have to take the vehicle in to have the gas gage recalibrated.
I have a 2012 lexus ct200h (same engine and battery as a prius) and i absolutely love it, never had any problems with it. Very reliable car.
Same deal for my 2011 Auris hybrid, it also has the Prius gen3 1.8L driveline. It has been incredibly reliable. (In fact the most reliable car i have ever owned, this includes bmw's, volvo's, a saab, a range rover)
In all the years i have owned it it only gave me 2 problems: 1x empty keyfob battery warning on the dash + 1x worn out 12v battery. This nearly got me stranded but i was able to get a jumpstart from a friend's motorcycle battery. That way the management electronics of the car were able to boot up after which the traction battery was able to start the engine and drive home without any problem. Bought a new 12V battery and installed it myself. Problem fixed.
Whenever the fueltank empty idiotlight starts blinking the car can still cruise 100km/60ish miles at 60mph. I never pushed it though. But it is good to know how the car will react when running out of fuel.
If I had a Prius, I could easily see myself getting 70-80 mpg while hypermiling. :P
Indeed you could. I have gotten many 90+ mpg tanks, as well as 3 at just a tad over 100 mpg. :)
So, from your experience in hybrid cars, which one has the highest battery power to drive linger distance by only battery after gas is out?
Thanks.
This is why I love my Toyota Prius v!!! Dude you are a rockstar!!!
For my 2013 Prius plug-in I got over 100 miles after low gas (the last gas bar blinking fast) and car keeps beeping randomly to make you look. It was 2.1 gallon left in tank. Plus I ALMOST drained the battery. You can't go over 40 in this state, even though you normally go 60ish on plug-in battery. I filled about 11 gallons from empty.
Excellent video
I have always looked into getting a Prius but I didn't know which one to get. I'm tied between a Prius C or Prius V
I'm curious to know how long it took the recharge the hybrid battery from that depleted state.
Amazing how clever the engineers were behind this design. It seems unlikely this fella realizes that MG1 will require a certain residual Traction (HV) battery capacity to rotate the engine to start it…To say nothing of the Aux battery having the remaining capacity to close the MSR’s. If I am mistaken, apologies in advance.
Very informative! I bought a 2015 Prius C One just like this one a couple months ago, and I've been filling up as soon as my cruising range hit zero every time. Good to know I can safely stretch it a little bit further if necessary!
Not a good idea at all purposely running any car out of gas. The fuel pump in the gas tank relies heavily upon the surrounding gas to keep the fuel pump cool.

I need someone to do one this same demo on the 2012 Prius Liftback... Thanks
Cool video! love the geeky techno music.
What type of fuel do you recommend using
If it's a hybrid.... you charge the battery as you brake. You could go farther then you did.
V. Useful! So after fuel gone 2-3 miles is the answer and around 35mph.
You'll get stranded if the 12v battery dies, for example sitting in the parked car, no idling, AC on. As one does in the summer. For that a little jumpstarter Li battery is sufficient.
Good experiment I like it.
My 2012 prius C ran out of gas and battery. I added more gas and it still will not start. I unplugged the Hybrid battery and have left it on the side of the road. I hope it will start up when I get back to it this afternoon after work.
How many 'right now' can we get to the mile?
Toyota's technology is amazing!!
Toyota bought the tech from GM looong ago. Def improved it though.
Yo, what year is that prius? I don't know they ever have the info cluster like that... I bet it's a custom third party one? How did you install it? How much did it cost?
Love it Jo👍
I’m going out on a limb here... but I’m guessing... go with me on this one... the car will stop?
Correct but there’s more to it. Mine stopped, got the check hybrid system warning. Had to put in 4 gallons, unplug the 12v battery for 10 min, then start the car. All errors are off, engine runs now. I didn’t get a low fuel warning.
Hello great video. BTW , your T-Shirt looks like a surgery doctor :) . Greetings from Romania.
Frankly, you got lucky. Prior gens of Prius would throw a code if it ran out of power and gas. That results in a tow to Toyota to have the code reset. You can’t/couldn’t just add gas and go.
The prius has no electric starter on the engine. It uses the traction battery and MG1 (the generator) to start the engine. If you run it out of gas and if the traction battery gets low enough it won't be able to start and you can't charge the battery. You will be truly up the creek. Not many places have the equipment needed to charge a prius high voltage battery to get the car running again. Most dealers don't have this equipment.
You cannot run down the traction battery on ANY electric vehicle. The cars are programmed to stop running before fully discharged. I have 3 prius, a volt, and an electric Smart. We just drive them. No worries. I ran out of fuel in the desert and limped into town. My brother accused me of trying to wean it off of gas.
It may be a rare thing, but it certainly isn't impossible or they wouldn't make the service equipment to charge the batteries. Leave your vehicle sitting long enough with a discharged battery, and it'll go completely flat all by itself.
I have an old ex-taxi Prius and if I leave it sitting for a week, the traction battery shows up as flat and sometimes I get really poor acceleration until the battery has had a few minutes to charge. It wouldn't surprise me if I left the car sitting for two weeks that it wouldn't have enough juice to start the engine. However I do have an old computer UPS that runs off 200 VDC (16 SLA batteries in series) so I guess I could always hook that up to put a little charge back into the batteries, or even hook up that battery pack in parallel with the car's just to start the engine the first time.
if you keep turning it off and on again and it try´s to start the engine it kan drain the hybrid battery, like they say, the charging equipment is rare. in Holland we only have 1 charger for the hole county...
This is correct. Continually attempting to start the engine will run the traction battery down to a point it can no longer crank the engine. If this happens you will most likely need to find a specialist to preform a rescue charge. Most of the time the dealers can’t even do this and they will recommend replacing the battery. I have seen this happen a handful of times.
Your the man! Awesome
I've run out of gas twice on my Prius while trying to push it to the limits on fuel capacity. I was able to get to a gas station both times to get gas. Although I have several other large cars, I still enjoy the little car...I wouldn't advise doing this though as you could do damage to the motor over time.
Bro very nice video .....By the way I bought the same model in Pakistan it's called Toyota Aqua not Prius...
Subscribed love from Pakistan
All the people hating have either not understood the definition of 'Hybrid' and the insane payoff it gives, or have never driven a Prius. Thumbs up from me, cool vid.
I'm sure you are at an Advantage as you are driving the C, Which is the mist fuel efficient Prius. Doubtful this would be similar in a V model.
Also all you Prius video makers need your video title to state year and generation and model (C, V, Touring, Prime, etc). Your results do not apply to all Prius types. Just saying.
Sagan Android hey, pretty sure he's driving a prius c in the video. Can tell by looking at the displays. Also, note the orange running along the length of the top half of the door.
I agree he should have added year and make but you know a lot about it just looking at the dash. He even showed us the back giving it away that it was a C.
dashcam says prius c15
What difference does it make, regardless of the model, same outcome! No gas, short distance using battery, car stalls, add gas.
Awesome video thank you my battery went out on my 2012 Prius I drove it with no Hybrid battery for one week average 28 MPG the engine just stayed on continuously Toyota said it's okay I put a new Hybrid battery in it and the average back to 52 MPG
can u push it or wheels are lock?
Can you put E85 in a Prius ?
I've had both 2008 Prius and 2013 Prius V. Both were able to run a good few miles after the low fuel warning light came on. But I love my cars too much and rarely go below the light.
On some vehicles, if ran low or out of gas, this will throw off the fuel gage reading or worst yet you will have to take the vehicle in to have the gas gage recalibrated.
Thanks Jo-Check my 2013 Prius ran out of gas and Battery today. Tow driver brought gas but car didn't Restart.
Had car towed home, it's Sunday. However I don't think that was a full 5 gallons and the Light still blinked after gas was in the car.
My question is: Will I be in trouble if I tell Toyota what happened? If the whole battery needs to be replaced., If the car doesn't eventually start after I add more gas.
I truly think the Tow driver didn't bring enough gas. All the Electronics are working Just that the ready light won't come on. I didn't know I was out of Gas.
When my tank is near E I can barely make it down the road xD
Hi JO-Check Im owner too of prius c 2014 Im from Latinoamerica Paraguay, as I saw with ODBII connector the SoC of the battery is from 40% to top 70 % according to my calcutaion is about 500Wh only
I kind of like how Toyota lets you go past this failsafe. I wonder if it works the same for my fusion hybrid.
DoorisJ. Try it. Be sure to take a gallon of extra fuel
Thank You
My 2007 gen 2 in Australia has an EV button...Can run ev mode for around 1 km if under 45km/h (approx)...By the way it still gets after 10 years 4.5 litres per 100km's which in miles is 63 mpg
Similar for me, only my battery is worn out (ex-taxi) so the EV button only gets me 50 metres, or maybe 100 if I've just done a lot of regen braking! I have wondered whether replacing the battery would increase fuel efficiency but I'm still getting 1000km per tank and I find that pretty impressive.
Awesome thanks.
If you try to see how far can you get you must turn off the AC. You could do another 5 mi
at least he shut it off after the battery died, but ya... real good test of range.
You should say Prius C on the title, not just Prius.
We have a 2016 Prius C and when the distance estimation remaining hits anywhere near 10 miles left my wife starts to get really nervous. I know that at 0 there are still several miles left with gas and more remaining with the battery cell. Still she gets mad at me. :)
Would be way more fun if you discharge 12v battery as well.
I've done this by sitting in the car, parked,no idling, with AC on. Car could not start. But a simple little portable jumpstarter takes care of that easily.
This video in my opinion, proves that Hybrids do make sense especially around town. I believe he would have gotten more than the 1.4 miles with the A/C off and sitting in city traffic.
It's a Prius C!! They're so cute. And they do have much smaller batteries than the regular Prius which probably impacts the miles driven in EV mode.
Perhaps it needs an emergency diesel generator. Take a hint from ships at sea. Or you could have a foldable windmill generator and/or solar cell panels.
The problem with owning a Prius is you start getting over conscious on the MPG meter. I covered mine and check it only once in a week. I am getting 50mpg average.
Cool video, (except music, I really hate music in these videos). You aren't ever supposed to let gas completely drain from the gas tank, but for the sake of information of "just knowing" this real-time knowledge of information is well worth it!! One time, should not do any damage, and those parts need changed eventually anyhow, in the Prius probably every 400,000 miles! LOL. Great video!!
doesn't that damage the battery?
frequent fuel voids on 2nd generation prius is a good way to ruin the traction battery. if it's an old battery the sudden loss of synergy places power load on t.b. causing some of the individual cells to "pop."
.......
the only problem with this kind of experiment is that you can burn the fuel pump.
fuel pomp haha
I'm really trying to be a better person on and offline. But this is really testing me.
Why?
went 96 miles on empty 0.5miles on battery with a HCH
unfortunately got a p0420 code 15miles after fill up
Don't forget gasoline changes volume, with changes in temperature. A gallon @66 degrees weights more than a gallon @76 degrees. In America the tax only calculates to a even number if you buy ten gallons like the man from Texas.
Knowing that at 0 gas mpg left but you still have 1.5, some will stretch that out.
Would not recommend running low on fuel. Doing so will expose the fuel pump which intern will overheat and destroy the pump.
At 5:50, the hybrid system cuts out when normally at this point, the fuel engine would turn on to prevent further discharge. The big READY light next to the fuel gauge turned off to indicate this... So from that point on, you are coasting :) Power steering will still work on the normal 12V battery, but will not work optimally because there is no power left.
This is quite a lame test, because Toyota has figured this out beforehand of course and you should have read in the manual about the READY light.
Have you ever wash the engine
So what starts the gasoline engine of the Prius is it the 12v battery or the hybrid battery?
The Prius uses the high-voltage (hybrid) battery to start the car, using the MG1 motor. There is no conventional starter motor.
@@aprilkolwey4779 so in an experiment where the Prius was first made to run out of gas and subsequently made to run on ev mode till the hybrid battery drained and the car stalled ... It should not be possible to start the Prius again. Yet in all such experiments people just filled up the car with gas and we're able to start the car ... How did that happen. I am just not able to understand. Could you explain this?
@@sanjaykumarsingh1970 I'm not entirely sure, but my best guess is that the car prevents you from draining the battery fully (maybe only down to about 5% left?) so that it still has some power to start the engine after more fuel is added.
@@aprilkolwey4779 Thanks for taking the time to reply .... wow that actually sounds like a very logical answer and would be a very smart and prudent thing to plan for ... Toyota engineering team has done a fine job here but that brings me further to another question. There will be a day when your hybrid battery conks out and your prius refuses to start. I have heard that this error can be bypassed and your hybrid can run purely on gas. Granted that the mileage will now be poor but it will start. What do you think is starting the engine.? My best guess is it's still the hybrid battery. It will work in the interim to start the car but not use the traction motor. Rest of the functions like charging of the hybrid battery etc is still maintained by the car electronics. What do you think? Sorry I am asking you these questions as I purchased an old Prius ... A 2010 model. It's done 160k miles and still runs fine but someday the inevitable will happen and I should know how to get myself out of a sticky situation like this. Thanks.
Nor auto here in france is useless they have no good staff personnel when the filter of my car suddenly remove all the oil came out until its empty but the car still working and it didnt overheat good thing about hybrid car but i dont know if it will last long. today its almost 4 month using my car still no problem
I ran my 2008 out gas 3 times & had no problems what so ever.. I have 185,000 miles on it now. The piston rings are shot. Other than that, she still runs great. Putting a qt of oil in every 1,000 miles until she dies. Hoping for 200,000!
Clean your p c v valve if it’s plugged it pushes oil out because your inside of your engine isn’t breathing 😮💨 those engines run forever 300k unless you drove with no oil. Put motorkote in your engine for extra protection.
Dont think folk ever did this before youtube
Hey that's a great video I was always wondering what would happen with my Prius V if I let it run out of gas. Funny thing after liking this video my Prius V absolutely refuses to let me in. Only my wife can get in that car now!
I know this isnt what this video is about but how slugglish does the car feel (with gas and battery lmao)? I current have a 2001 Corolla with a 4 speed that is decent when floored but horrible at any other time
The Rusty Scooter Its no race car... lol It gets to 80mph on a freeway ok and holds it. Takes a while to get use to a hybrid but if your going for good fuel economy then get one. Go by a dealership and take one for a test drive.
Yea im use to my Corolla and my moms 2015 with a CVT so neither one are mind blowing 0-60 but that doesnt stop me from keeping up with 80-85 mph traffic. I was looking between a gen 2 (2007-2009) or a C because of how cheap they have become. I was also wondering how easy it is for DIY work? I know they are bulletproof but how easy it it to change out a strut or something for example?
The Rusty Scooter if you are looking for a Prius I don’t recommend the C it’s really compact if you are planning on tweaking it. Just go for the regular and up.
I like the regular Prius it just seemed that in terms of "driving enjoyment" (Im fully aware its a Prius so its not a drivers car) the C overall is tighter in the corners, has better steering and a better chassis versus the liftback
Prius in general are sluggish. If you want a fast car that is a hybrid get a Chevy Volt which is about as good as you can get without going full EV. [do not bring up 918 spyder...]
I wish fuel was that cheap here in the UK lol
you stopped in the middle of no where😂
What’s the song that starts at 0:34
Completely running out of gas can damage the fuel pump which uses fuel for lubrication.
Some cars are worse about burning up fuel pumps from low fuel than others. I know GM vehicles burn up fuel pumps quite easily if you let the tank get less than 1/4 filled.
It's not just that he could be damaging.. the hybrid battery controller, despite showing zero-full charge in the dashboard, does actually always keep the battery between 40-80% (approximate numbers) off actual charge. This is done to prevent overcharging or depletion as that can reduce the life of the battery or even damage individual cells.
So, in normal circumstances the engine can always turn on and charge the batteries to ensure their charge never goes below 40%. However, when the engine doesn't start anymore (no fuel for example) then the hybrid battery controller cuts off energy to the traction motor to prevent the batteries going under 40%, but I believe AC and other things running from HV are allowed to run. If one continues with AC on I believe eventually the battery will eventually near depletion and cut off (low voltage threshold). If you arrive to this point, it's quite possible you damage some cells as they never share the same wear/voltage...
oh well
This isn't the 80s. Cars will cut the pump off when there's no power or it's spinning too quick.
+No: I don't know of any that cut off the fuel pump until the engine has been off for the length of time that is programmed into it. Lots of fuel pumps die this way, partly because it is also cooled by the fuel. In Mesa, Arizona, shop owner Mark Salem once remarked on his radio show that nearly all the fuel pumps he replaced were for college students who kept their tanks nearly empty.
those sunglasses are obnoxious
