Compass calibration adjustment
Perform this adjustment in an open area free from steel structures and
high voltage lines.
For optimum calibration, turn off all electrical accessories (heater/air
conditioning, wipers, etc.) and make sure all vehicle doors are shut.
1. Start the vehicle.
2. Locate the compass module
mounted on the base of the mirror.
3. Insert an appropriate diameter
rod (paperclip) into the switch
access hole underneath the compass
module.
4. Gently press the switch for 2 to 4
seconds until CAL and a direction
are displayed on the trip computer.
(To exit CAL mode before
performing a compass adjustment, turn the ignition OFF.)
5. Release pressure from the switch.
6. Slowly drive the vehicle in a circle (less than 5 km/h [3 mph]) until
the CAL indicator turns off. This will take three to five circles to
complete calibration.
7. The compass is now calibrated.
