PRELIMINARY CHECK FOR THERMOMETER
1. COOL DOWN CHECK
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 DI-28, "

Calibration Procedure for CompassEKS00GBX
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.
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.
