- Turn ON the ignition, with the engine OFF.
- Press and hold the switch for the compass, which may be depicted as COMP, COMPASS, or on/off (w/UE1) depending on the type of mirror on the vehicle, until a zone number appears on the compass display.
- Depress the switch for the compass to select the desired zone number.
- Wait 5 seconds. The display will return to a compass heading. The variance procedure is now complete.
- Calibrate the compass. Refer to Compass Calibration mentioned above.
