ENGINE OIL MAINTENANCE INFORMATION
lEngine oil maintenance information displays maintenance intervals of engine oil.
lWith ignition switch ON position, engine oil maintenance information is displayed on odo/trip meter display
for 5 seconds.
NOTE:
Refer to Owner's Manual for setting.
METER ILLUMINATION CONTROL
When the lighting switch is turned ON, the odo/trip meter switch (1)
can be used to adjust the brightness of the combination meter illumi-
nation.
CLOCK
With ignition switch ON position, combination meter displays clock
on clock display. Time can be adjusted by clock switch (1). Clock can
be adjusted to 12-hour or 24-hour cycle clock.
NOTE:
If the battery cable is disconnected, the clock displays the time 12:00
in 12-hour mode.
AMBIENT AIR TEMPERATURE INDICATION
Combination meter displays ambient air temperature on clock display.
With ignition switch ON, “°C” blinks for a while. Ambient air temperature indication can be selected between
Centigrade and Fahrenheit.
Combination meter reads ambient air temperature signal from ambient sensor.
Signal is supplied
lfrom combination meter terminal 49
lthrough ambient sensor terminals 1 and 2
lto combination meter terminal 50.
When a temperature detected by sensor rises, combination meter controls increase of the indicated tempera-
ture depending on engine heat and other effective factors.
lIf the vehicle speed is more than 20 km/h, the indicated temperature rises according to the vehicle speed.
lIf the vehicle speed is less than 20 km/h, the indicated temperature is maintained.
When a temperature detected by sensor falls, the temperature is indicated immediately.
NOTE:
The range indicated on the display is between-30 and 60°C for Centigrade or between-22 and 99°Ffor
Fahrenheit.
lWhen the temperature is from-40°C(-40°F) to-30°C(-22°F), “--°C” is indicated on the display as
over range.
lWhen the temperature is under-40°C(-40°F) or over 60°C(140°F), nothing is indicated.
lWhen indicated temperature becomes less than 3°C(37°F), ambient air temperature indication blinks
warning. After blinking for 20 seconds, only “°C” blinks. At more than 4°C(39°F) the display stops blink-
ing.

Fuel Gauge Fluctuates, Indicates Wrong Value, or VariesEKS00L8V
1.CHECK FUEL GAUGE FLUCTUATION
Test drive vehicle to see if gauge fluctuates only during driving or at the instant of stopping.
Does the indication value vary only during driving or at the at the instant of stopping?
YES >> The pointer fluctuation may be caused by fuel level change in the fuel tank. Condition is normal.
NO >> Ask the customer about the situation when the symptom occurs in detail, and perform the trouble
diagnosis.

NO >> GO TO 3.
2.QUESTION 2
Was the vehicle fueled with the ignition switch ON?
YES >> Fuel the vehicle with the ignition switch OFF. Otherwise, it takes a long time to move to FULL posi-
tion because of the characteristic of the fuel gauge.
