COMPASS AND THERMOMETER
1. Turn the ignition switch to the ON position.
2. Cool down ambient sensor 2 with water or ice.
Does the indicated temperature drop?
YES >> GO TO 2.
NO >> The system is malfunctioning. Check the system following “INSPECTION/COMPASS AND THER-
MOMETER”. Refer to "INSPECTION/COMPASS AND THERMOMETER".
2.WARM UP CHECK
1. Leave the vehicle for 10 minutes.
2. With the ignition switch in the ON position, disconnect and reconnect ambient sensor 2 connector.
Does the indicated temperature rise?
YES >> The system is OK.
NO >> The system is malfunctioning. Check the system following “INSPECTION/COMPASS AND THER-
MOMETER”. Refer to "INSPECTION/COMPASS AND THERMOMETER".

Calibration Procedure for CompassINFOID:0000000003533503
The difference between magnetic North and geographical North can sometimes be great enough to cause
false compass readings. In order for the compass to operate accurately in a particular zone, it must be cali-
brated using the following procedure.
Symptom Possible causes Repair order
No display at all 1. 10A fuse.
2. Ground circuit.
3. auto anti-dazzling inside mirror.1. Check 10A fuse [No. 12, located in fuse block (J/B)].
Turn the ignition switch ON and verify that battery positive
voltage is at terminal 6 of auto anti-dazzling inside mirror.
2. Check ground circuit for auto anti-dazzling inside mirror.
3. Replace auto anti-dazzling inside mirror.
Forward direction indi-
cation slips off the mark
or incorrect.1. In manual correction mode (Bar
and display vanish).
2. Zone variation change is not
done.1. Drive the vehicle and turn at an angle of 90°.
2. Perform the zone variation change.
Displays wrong temper-
ature when ambient
temperature is between
−40°C (−40°F) and
55°C (130°F)1. Check operation.
2. Ambient sensor 2 circuit.
3. Ambient sensor 2.
4. Auto anti-dazzling inside mirror.1. Perform preliminary check shown above.
2. Check harness for open or short between ambient sensor 2
and auto anti-dazzling inside mirror.
3. Replace ambient sensor 2.
4. Replace auto anti-dazzling inside mirror.
Displays SC or OC 1. Ambient sensor 2 circuit.
2. Ambient sensor 2.
3. Auto anti-dazzling inside mirror.1. Check harness for open or short between ambient sensor 2
and auto anti-dazzling inside mirror.
2. Replace ambient sensor 2.
3. Replace auto anti-dazzling inside mirror.

Zone Variation Chart
1. Determine your location on the zone map.
2. Turn the ignition switch to the ON position.
3. Press and hold the mode (N) switch for about 8 seconds. The current zone number will appear in the dis-
play.
4. Press the mode (N) switch repeatedly until the desired number appears in the display.
Once the desired zone number is displayed, stop pressing the mode (N) switch and the display will show a
compass direction after a few seconds.
NOTE:
Use zone number 5 for Hawaii.
CORRECTION FUNCTIONS OF COMPASS
The direction display is equipped with automatic correction function.
If the direction is not shown correctly, carry out initial correction.
INITIAL CORRECTION PROCEDURE FOR COMPASS
1. Pushing the mode (N) switch for about 10 seconds will enter the initial correction mode. The “CAL” icon
will illuminate.
2. Turn the vehicle slowly in an open, safe place. The initial correction is completed in approximately one
and a half turns.
NOTE:
In places where the terrestrial magnetism is extremely disturbed, the initial correction may start automatically.
