That's Uncle Henry doing the CYA thing. As far as I know, there's no disabling it.

 

it also sounds repeatedly as you drive (like the seatbelt reminder)

 

BigTRQ - It’s really true that I average ~425 per tank. I live in Houston, TX which is mostly flat land and most of my daily driving is at highway speed with very few stops. I can run about 2 weeks between fill-ups.

RockyJSquirrel – Yes I mean the light on my dash is not enough because I DON’T HAVE ONE. As I mentioned in my previous post (go ahead and read that now, I will wait for you) the ONLY warning that I receive is the “LOW FUEL” message on the mini message center (also on page 4 of my Owner’s Guide) which is often obscured buy the spoke of the steering wheel. I DO however have a lighted indicator for Service, Battery, Engine, Brake, ABS, Seatbelt, Airbag, Door Ajar, High Beams, and Speed Control. But alas there is NO light on my instrument panel nor do I recall an audible warning when the level in the tank reaches the set point for low fuel.

As to your condescending remarks, I routinely look at my instrument panel to monitor speed, temp., r.p.m. and yes, fuel while driving. However while operating in dense, heavy traffic in Houston I find it best to concentrate on the vehicles around me to avoid sheet metal showers rather than focus on the instrument panel. Just a little something that I picked up during my 8 years working with aircraft in the Army.

Many of the trucks are sold to people who are not city slickers and where gas stations are not at every corner. They are also driven by other members of the family who are not as concerned as they should be about the amount of fuel in the tank. There can also be about a quarter a gallon difference in price in some areas within the "stupid" 50 mile range.

 

I guess the question is "how empty should it be before a warning"?
