ohh now im curious too, someone wanna test it out for us? you know just so were 'sure'

 

actually type in "fuel light" and you'll find many threads of people that actually have done it.

 

yes we do have a waser fluid light and warning and it annoys the crap outta me when i drive somewhere far and use it all up.

back on topic my light always comes on when i have about 30 mpg approximate displayed.. when thats used up you have a 2 gal reserve so yes you can make it in 20 miles back home. considering we get over 20mpg

 

I dont think that range is accurate. I bet there's about 2 gals left in the tank when it comes on.

 

When my light comes on, I can go about 35 miles before the Range Approx reads 0. If I don't fill up at that point, then I can go 10-20 more miles before filling up, and I fill up about 16 gallons, which means theres about 1 gallon left in the tank.

 

the system in the lexus seems very conservative. based on what ive read here and other forums, zero doesnt mean zero. i have a ford product and its spot on - when it says i have 20 miles left, i fill up and the numbers verify just about one gallon was left. i guess toyota wants to be conservative?

 

I think it comes down to liability. Toyota doesn't want to be sued because some guy runs out of gas in the middle of no where and the car said he had 1 mile to go (even though he's 50 miles from a gas station). They've already been sued already because some people ran over their child in their own driveway for not making reverse cameras standard on lexus' so I don't exactly blame them. Oh yah, I've gone about 10 miles with the computer saying 0. I know it's very conservative, but just having it there saying 0 made me nervous.

 

thats the first i heard about the backup camera thing ... when did that happen? that definitely explains the electronannies on the nav.

 

I heard it on the radio, probably about a year ago.

 

thx for the info

 

Our tank size is approximately 17.1gal. I've driven the car down to exactly 0miles left (and the needle perfectly on E) right when I arrived at the gas station and pumped about 15.2-15.4 gallons of gas. So yes there's about another 1.5-2 gallons of reserve.

I also remember there being another thread of someone actually run their 2IS to the point where there is absolutely no gas left. We can search for that thread. If I recall it was about 50miles after the approx. miles says 0 which is about right for 1.5-2 gallons of reserve

 

Don't forget when refueling air pockets may prevent truly filling the tank & it is impossible to use all the fuel in the tank.


My 94 Mustang would often fail to start with low fuel when parked on a steep hill heading uphill. I would have to coast/ push to level ground to start the car.
