Compass: Adjustments
Compass Calibration Adjustment
1. Start the vehicle and locate the compass module mounted on the base of the mirror.
NOTE: For optimum calibration, drive to an open, level location away from large metallic objects or structures. Switch off all non-essential
electrical accessories (rear window defrost, heater, A/C, map lamps, wipers, etc.) and make sure all doors are shut.
2. Press the button located underneath the compass sensor module gently for between four and eight seconds until CAL and a direction are
displayed on the message center and release the button.
NOTE: To exit CAL mode before performing a compass adjustment, turn the ignition switch to the OFF position.
3. Release the button and drive slowly in a circle no more than five times at no more than 5 km/h (3 mph) until CAL no longer appears on the
display.
NOTE: If the CAL indicator does not turn off after the vehicle has been driven in a circle no more than five times, demagnetize the vehicle and
repeat the procedure.
