Calibration Procedure

The compass is self-calibrating, eliminating the need to manually set the compass. Occasionally, the calibration process on a new vehicle may not be complete, causing the CAL symbol to illuminate. In order to correct this problem, drive the vehicle less than 8 km/h (5 mph) through 3 complete 360 degree turns. The CAL symbol will then turn OFF and the compass will function normally. If the compass appears erratic and the CAL symbol does not appear, you must manually put the compass into the calibration mode.

  1. Turn ON the ignition.
  2. Press the MODE button until the compass/temperature mode appears.
  3. Press and hold the RESET button on the overhead console for approximately 10 seconds, or until the display reads CAL.
  4. Release the RESET button and drive the vehicle less than 8 km/h (5 mph) through 3 complete 360 degree turns. The CAL symbol will turn off when the compass is calibrated, and the compass will function normally.
