Low Fuel Light at 22 Miles To Empty?
2024 LS. Was running behind yesterday and didn’t have time to fuel up when I wanted.
The distance to empty hit 50miles, no light no warning. 30 miles DTE. Nothing. Finally with 22 miles to empty I got a “Low Fuel” warning in the display and a little orange fuel light came on.
It’s not a huge deal but is that normal the car only warns at basically 20 miles left? I’ve had several other Lexus and Toyota models before and they all had fuel lights come on way way earlier than this.

I have not. I will pull out the owner's manual too. Thanks for the suggestion, worth a look.

I wouldn't trust the DTE. Toyota products are very conservative on stuff like this. I did a run-to-empty test on my Tundra, and once the low-fuel light illuminated I went 80 miles before the engine started have fuel starvation. When the low-fuel light illuminated the DTE was 20 miles, then it when blank. That figures to at least four gallons remaining when the low-fuel light illuminated, on a 26-gallon tank. So for LS I'd estimate about 3 or 4 gallons remain when the low-fuel light illuminates. It's all kind of academic anyway, who runs out of fuel?

My 500h has a 21.6 Gallon tank (82 liters), if the car says the range is 13 Miles (20 km's) then i can only fill the tank with about 19 Gallons (72 liters) so mine has about 2 Gallons or 8 liters safety build in.

I think the Ls460's are the same way, once it's below 20 miles of "range" is just says "low fuel level". At that point there's still ~2 gallons left (so 40-50 miles) so plenty of leeway. Only get it that low cruising on the highway when I know there's a gas station every 5 miles.
@Higgie because we like it that way
lol we don't teach our kids metric in primary school, we only end up learning it in college if you get a technical degree, then it depends on what company you use that technical degree in. Some companies, use standard (English), some use metric (SI), and some use both!

Well pulled out the manual. Sounds like those who way the DTE is inaccurate are correct.
Going by memory but 21.7 gallon tank. Low Fuel warning comes on with 3.4 gallons left.
The car had 22 miles DTE and took a hair under 19 gallons. So still 2.7 gallons left. Seems about right.

Gas Gauge
My gauge seems inaccurate. It lingers around 3/4 full for close to 200 miles, then starts to drop.
Yesterday I filled up in Evergreen, Colorado and drove to Hays, Kansas. My gauge was slightly below 1/2 when I got to Hays. I topped the tank off and was astounded that it only took 10 gallons. Now this is a downhill drive. I was driving 75-80 mph in eco mode.
360 miles on 10 gallons! I was expecting around 27mpg.
Has anyone else gotten this kind of mileage with an LS500?

Soon as I push it to around 85 drops south of 24mpg.
I am usually not to gentle unless traffic dictates it.

Here is what I learned if it could help anyone.
Low Fuel Light Came on with 20 Mile Range and at Gas Pump near empty with 396 Miles since last fill up
Took 18.7 Gallons to fill. (stopped at 2 Clicks)
Costco has 93 Octane I like to use
Although gauge indicator calculates 20.2 MPG average, doing math of 396 miles / 18.7 gallons =21.2 MPG.
There are some errors built in such as was fuel topped off exactly as filled up with 2 clicks.
With 2 to 3 gallons left still left in tank, There is a built in safety range of about 50-60 miles based on my driving conditions.

So Lexus is as paranoid about running out of gas as a engineer flying his newly designed airplane. Lol
@PGA71 why are we doing the "2 clicks", you know that could put gas into the evap carbon canister and damage it over time? Or at least I've heard that. I thought gas tanks were deigned to have a certain amount of empty space in them for pressure and vapor and safety or whatknot. (can you tell I don't know how to design a gas tank?
) You do you, but just curious.
