NORMAL OPERATING CONDITION

INFORMATION DISPLAY

INFORMATION DISPLAY : Description

INFOID:0000000009189367

OIL LEVEL DISPLAY

After mounting/removing of battery or combination meter, the combination meter power supply is cut off tem-
porarily. Therefore, the engine oil amount data may be erased from the combination meter, causing the oil
level to be not displayed. Refer to 

MWI-26, "INFORMATION DISPLAY : System Description"

 for the condition

that the combination meter reads the resistance of oil level sensor. 

AMBIENT AIR TEMPERATURE

For the ambient air temperature display, the value is displayed on the information display after the signal from
ambient sensor is corrected by the combination meter. Therefore, the indication value may not match the
actual ambient air temperature. Refer to 

MWI-26, "INFORMATION DISPLAY : System Description"

 for details

on the correction process. 

POSSIBLE DRIVING DISTANCE

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 lmp 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 performed in such a case.
