Compass calibration adjustment
The compass may need calibration adjustment if:
• the compass ZONE is set correctly and the trip computer display
window is not showing the correct heading
• "CAL" is displayed in the trip computer display window
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. Locate the compass module
mounted at the base of the mirror.
2. Start the vehicle.
3. Press and hold the button on the
upper left hand corner of the
compass module 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.)
4. Release pressure from the button.
5. Drive the vehicle slowly (less than 5 km/h [3 mph]) in circles until the
"CAL" indicator turns off. This will take three to five circles to complete
calibration.
6. The compass is now calibrated.
