Another thing I noticed after I filled the tank up night before last is that the miles to empty range reads about 200 miles and has stayed there for the last 30 miles. Is there a way to reset this? I've reset the average MPG a couple of times and the trip meter as well.
The miles to empty is not a user reset-able thing and is based on average mpg over some unspecified interval (not either trip values) and the amount of gas remaining in the tank. I reset the miles/average mpg/time for trip1 when I refill the gas tank and I reset the values for trip2 at the start of a trip so I may reset trip2 several times for each trip1 reset unless it's a long trip spanning more than one gas tank.

I've found the average mpg display can vary by a couple mpg versus a calculated tank filling mpg, but over many tanks the average display value is very close to the average calculated value. I suspect that variation in tank filling is the main reason for the tank-to-tank variation of displayed value versus calculated.
