Instruments and Controls 4-11 Compass The vehicle may have a compass in the Driver Information Center (DIC). Compass Zone The zone is set to zone eight. If you do not live in zone eight or drive out of the area, the variance needs to be changed to the appropriate zone. To adjust for compass variance, use the following procedure: Compass Variance (Zone) Procedure 1. Do not set the compass zone when the vehicle is moving. On an automatic transmission vehicle, only set it when the vehicle is in P (Park). On a manual transmission vehicle, only set it when the vehicle is stopped. Press the vehicle information button until Press To Change Compass Zone displays. 2. Find the vehicle's current location and variance zone number on the map. Zones 1 through 15 are available. 3. Press the set/reset button to scroll through and select the appropriate variance zone. 4. Press the trip/fuel button until the vehicle heading, for example, N for North, is displayed in the DIC. 5. Calibrate the compass. See "Compass Calibration Procedure" following. Compass Calibration The compass can be manually calibrated. Only calibrate the compass in a magnetically clean and safe location, such as an open parking lot, where driving the vehicle in circles is not a danger. It is suggested to calibrate away from tall buildings, utility wires, manhole covers, or other industrial structures, if possible. If CAL appears in the DIC display, the compass should be calibrated. If the DIC display does not show a heading, for example, N for North, or the heading does not change after making turns, there may be a strong magnetic field interfering with the compass. Interference may be caused by a magnetic antenna mount, magnetic note pad holder, or any other magnetic item. Turn off the vehicle, move the magnetic item, then turn on the vehicle and calibrate the compass.
