Compass Zone Adjustment
When something affects the compass readings, typically the compass
corrects itself after a few days of operating your vehicle in normal
conditions. If the compass still appears to be inaccurate, a manual
calibration may be necessary.
1. Determine which magnetic zone
you are in for your geographic
location by referring to the zone
map.
2. Turn ignition to the on position.
3. Press and hold the 7 and 9 radio
preset buttons together for
approximately five seconds until
ZONE XX appears in the CID.
4. Press and release the 7 and 9
radio preset buttons together,
repeatedly until ZONE XX
changes to the correct zone
(1–15) in the CID.
5. The direction displays after the buttons are released. The zone is
now updated.
Compass Calibration Adjustment
Most geographic areas (zones) have a magnetic north compass point that
varies slightly from the northerly direction on maps. This variation is four
degrees between adjacent zones and becomes noticeable as the vehicle
crosses multiple zones. A correct zone setting eliminates this error.
Perform compass calibration 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 the
vehicle’s doors are shut.
1. Start the vehicle.
2. Press and hold the 7 and 9 radio preset buttons together for
approximately 10 seconds until CAL appears. Release the buttons.
3. Drive the vehicle in a circle slowly (under than 3 mph [5 km/h]); it
may take up to five circles to complete calibration.
4. When the CAL display changes to the direction value (N, S, E, W,
etc.), the compass is calibrated.
