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 compass sensor mounted at base of mirror.
3. Insert a paperclip into the small
hole on the bottom of the compass
sensor. Hold down until ZONE
appears in the instrument cluster
display. Continue to hold down until
ZONE disappears and CAL is
displayed.
4. Press and hold the control until CAL appears in the display
(approximately eight seconds) and release.
5. Drive the vehicle slowly (less than 5 km/h [3 mph]) in circles until
CAL indicator turns off (4–5 complete circles).
6. The compass is now calibrated.
MESSAGE CENTER (IF EQUIPPED)
With the ignition in the ON position,
the message center, located on your
instrument cluster, displays
important vehicle information
through a constant monitor of
vehicle systems. You may select
display features on the message center for a display of status preceded
by a brief indicator chime. The system will also notify you of potential
vehicle problems with a display of system warnings followed by a long
indicator chime.
