DIC Compass Your vehicle may have a compass in the Driver Information Center (DIC). Compass Zone The zone is set to zone eight upon leaving the factory. Your dealer/retailer will set the correct zone for your location. Under certain circumstances, such as during a long distance cross-country trip or moving to a new state or province, it will be necessary to compensate for compass variance by resetting the zone through the DIC if the zone is not set correctly. Compass variance is the difference between the earth's magnetic north and true geographic north. If the compass is not set to the zone where you live, the compass may give false readings. The compass must be set to the variance zone in which the vehicle is traveling. 3-63
