Instrument Cluster 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 RESET FOR ZONE SETTING / PRESS RESET FOR CALIBRATION following. 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 RESET FOR ZONE SETTING / PRESS RESET FOR CALIBRATION following. RESET FOR ZONE SETTING 1. Determine your magnetic zone by referring to the zone map. 3 2 1 15 2. Start the engine. 3.
