NORMAL OPERATING CONDITION

NORMAL OPERATING CONDITION

INFORMATION DISPLAY

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.
