NC '19 Rav4 Hybrid Limited, Entune 3.0, Adaptive Headlights, Advanced Technology Package
You are dipping into a reserve area between the low fuel warning light and the E display. Nothing wrong with that as long as you are very aware that truly running out of fuel can get very inconvenient and result in a trip to a dealers on a tow truck. A gas can doesn't help. There is a splash area, an auto shut off separating that from what Toyota calls the usable fuel area. Then the low fuel warning light, a reserve, then the empty light and even below that a reserve. So you have two reserves that are below where you start to get warnings.Interesting... The gas gauge on my 2022 always shows a needle width beyond F at every fill auto shut off since I bought it. The Low Fuel waring light consistently comes on when DTE is 30-32 and the needle is at least one needle width above "E" (usually more). So far I have had 18 fill ups where the pump auto shut off at 10 or more gallons (mostly 11-12 gals and a couple of 13s). I Never, Ever top off.
I suspect Toyota changed something with the fuel system, tank, gauge or software on the 2022s or my RAV4 has a different kind of fuel issue because the whole 9.8 gallon capacity and splash area theory does not seem to apply in my case or some other 2022 owners that I have seen.
Those areas and when shut off and warnings are to be triggered are set by the standards bodies SAE and NIST. As is how large a fuel tank sixcan be advertised.
