Work Procedure
INFOID:0000000007565095
1.
Press and hold the compass switch for 3 – 9 seconds.
2.
The current zone setting appears on the compass display.
3.
Find the current geographical location number in the zone varia-
tion chart.
4.
Select the new zone number. (Press the compass switch until
the new zone number appears on the compass display.)
5.
After select the new zone number, the compass display will
automatically shows a direction within a few seconds.
6.
Perform the following calibration procedure for more accurate
indications.

CALIBRATION (COMPASS)
Work Procedure
INFOID:0000000007565096
NOTE:
The compass calibrates itself under normal driving conditions. However, occasional circumstances may cause
the compass to operate inaccurately. Example: Driving from rural (wide open) areas to crowded city areas, or
if an aftermarket (i.e., non original equipment) antenna with a magnetic base is attached to the vehicle. Cali-
brate the mirror compass if the display shows only one direction or a limited number of directions.
NOTE:
• If “magnetic hats” are used in the dealership for vehicle identification, remove the hat from the vehicle before
performing the following steps. Do not put the hat back on the vehicle after the procedure is completed.
• Drive the vehicle to an open level area; away from large metallic objects, structures, and overhead power
lines.
• Turn off “non-essential” electrical accessories (rear window defrost, heater/air conditioning, wipers) and
close the doors.
1.
Verify the correct compass zone setting for the geographical location. Refer to
2.
Press and hold the compass switch for more than 9 seconds.
3.
“C” is displayed on the compass display when calibration starts.
4.
Drive slowly [less than 8 km/h (5 MPH)] in a circle until the “C / CAL” is replaced with primary headings (N,
NE, E, SE, S, SW, W, or NW).
NOTE:
This will require driving at least 2 complete 360 degree circles, 3 complete circles may be required.
5.
The compass calibration procedure is now complete. The compass should operate normally.
NOTE:
If at any time the compass continually displays the incorrect direction or the reading is erratic or locked,
repeat the calibration procedure.
