Driver Controls Usually, when something affects the compass readings, the compass will correct itself after a few days of operating your vehicle in normal conditions. If the compass still appears to be inaccurate, a manual calibration may be necessary. Refer to Compass zone/calibration adjustment. Most geographic areas (zones) have a magnetic north compass point that varies slightly from the northerly direction on maps. This variation is four degrees between adjacent zones and will become noticeable as the vehicle crosses multiple zones. A correct zone setting will eliminate this error. Refer to Compass zone/calibration adjustment. Compass zone/calibration adjustment Perform this adjustment in an open area free from steel structures and high voltage lines. For optimum calibration, turn off all electrical accessories (heater/air conditioning, wipers, etc.) and make sure all vehicle doors are shut. 1. Turn ignition to the ON position. 2. Start the engine. 3. Determine your magnetic zone by referring to the zone map. 4. From Info menu, select the Compass/Outside Temperature function. 5. Press and hold the RESET control until the message center display changes to show the current zone setting. 6. Release the reset control, then slowly press down again. 7. Press the SETUP control repeatedly until the correct zone setting for your geographic location is displayed on the message center. To exit the zone setting mode press and release the RESET control. 107
