Compass Calibration Procedure





1. Cycle the ignition switch to the "IG-ON" position and hold the "Auto" switch for 6 seconds until the zone number appears on the display.

Pushing the "AUTO" switch for 3 seconds turns the compass display ON or OFF.





2. Push the "AUTO" switch to select the number of the zone where the vehicle is located. See the map in figure 3 for zone reference.





3. Start the engine and push the "AUTO" switch for 9 seconds until "C" appears on the display.





4. Drive the vehicle slowly at 5 mph (8 km/h), or less, in a circle until the direction is displayed. If there is NOT enough space to drive in a circle, drive around the block until the direction is displayed.

Once the direction is displayed, the calibration is complete.

^ Do NOT perform calibration of the compass in a place where the Earth's magnetic field is subject to interference (underground parking, under a steel tower; between buildings, roof parking, near a railroad crossing, near a large vehicle, etc.)

^ During calibration, do NOT operate electric systems (moon roof, power windows, etc.) as they may interfere with the calibration.
