INFORMATION DISPLAY : Description
INFOID:0000000006221775
AMBIENT AIR TEMPERATURE
The displayed ambient air temperature on the information display may differ from the actual temperature
because it is a corrected value calculated from the ambient sensor signal by the combination meter. Refer to
MWI-20, "INFORMATION DISPLAY : System Description"
for details on the correction process.
DISTANCE TO EMPTY
The calculated distance to empty may differ from the actual distance to empty if the refueling amount is
approximately 15 (4 US gal, 3-1/4 Imp gal) or less. This is because the refuel control (moves the fuel gauge
needle quicker than normal judging that the driver is refueling the vehicle) is not performing.
