Compass Calibration

    NOTE: For optimum calibration, drive to an open, level location away from large metallic objects or structures. Switch off all non-essential electrical accessories (rear window defroster, heater, A/C, map lamps, and wipers) and make sure all doors are closed.
  1. Start the vehicle.
  2. NOTE: To exit CAL mode before carrying out a compass adjustment, turn the ignition switch to the OFF position.
  3. Press and hold the MODE button until CAL appears in the display, then release the MODE button.
  4. NOTE: If the CAL indicator does not turn off after the vehicle has been driven in a circle no more than five times, demagnetize the vehicle and repeat the procedure.
  5. Drive the vehicle slowly (less then 5 km/h ) in complete circles until CAL disappears from the display.
