COMBINATION METERS
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.

WARNING CHIMEPFP:24814
System DescriptionEKS00L9D
lBuzzer for warning chime system is installed in the combination meter.
lThe buzzer sounds at the following conditions:
–When combination meter receives buzzer output signal with CAN communication line
–When combination meter judges warning chime sound condition is found
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
lthrough 50A fusible link (letterG, located in the fuse and fusible link box)
lto BCM terminal 57.
With ignition switch in the ON or START position, power is supplied
lthrough 10A fuse [No. 1, located in the fuse block (J/B)]
lto BCM terminal 3.
Ground is supplied
lto BCM terminal 55
lthrough grounds M21, M80 and M83.
LIGHT WARNING CHIME
With ignition switch in OFF or ACC position, driver's door open, and lighting switch in 1ST or 2ND position, the
light warning chime will sound.
lBCM detects ignition switch in OFF or ACC position, front door switch (driver side) ON, and lighting switch
in 1ST or 2ND position. And then transmits buzzer output signal (light warning chime) to combination
meter with CAN communication line.
lWhen combination meter receives buzzer output signal (light warning chime), it sounds the buzzer.
NOTE:
For further details of combination switch, refer toBCS-3, "
COMBINATION SWITCH READING FUNCTION".
KEY REMINDER WARNING CHIME
Key reminder chime sounds, at the same time, when key reminder system starts operating.
key reminder chime also sounds when the following three conditions are simultaneously met.
lKey is inserted in the ignition key cylinder
lDriver¢s door is opened
lThe setting of driver¢s door lock knob is “LOCK”
For information regarding key reminder system, refer toBL-21, "
POWER DOOR LOCK SYSTEM".
LOW-FUEL WARNING CHIME
Low-fuel warning chime sounds, when low-fuel warning lamp is turned ON.
Combination meter sounds warning chime three times when low-fuel warning lamp turns ON.
