Compass Calibration Procedure





1. Cycle the ignition to the "IG-ON" position and check that the direction (N, NE, E, SE, S, SW, W, NW) appears on the compass display.





2. Push and hold the "N" switch for approximately 3 seconds until the zone number (1 - 15) appears on the display. Then push the switch to select the number of the zone where the vehicle is located.





See Figure 4 for zone reference.

NOTE

Pushing the "N" switch turns the compass display ON or OFF.

3. Once the correct zone is selected check that the direction appears on the compass display.





4. Start the engine and push and hold the "N" switch for about 6 seconds until "C" appears on the display.





5. 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 turn the vehicle around as shown doing two three-point turns in succession.

Once the direction is displayed calibration is complete.

NOTE

^ 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.
