To calibrate the compass, use the following procedure: DIC Warnings and Messages Messages are displayed on the DIC to notify the driver that the status of the vehicle has changed and that some action may be needed by the driver to correct the condition. Multiple messages may appear one after another. Some messages may not require immediate action, but you can press any of the DIC buttons on the instrument panel or the trip odometer reset stem on the instrument panel cluster to acknowledge that you received the messages and to clear them from the display. Some messages cannot be cleared from the DIC display because they are more urgent. These messages require action before they can be cleared. You should take any messages that appear on the display seriously and remember that clearing the messages will only make the messages disappear, not correct the problem. The following are the possible messages that can be displayed and some information about them. Compass Calibration Procedure 1. Before calibrating the compass, make sure the compass zone is set to the variance zone in which the vehicle is located. See "Compass Variance (Zone) Procedure" earlier in this section. Do not operate any switches such as window, sunroof, climate controls, seats, etc. during the calibration procedure. 2. Press the vehicle information button until PRESS V TO CALIBRATE COMPASS displays. Or, if the vehicle does not have DIC buttons, press the trip odometer reset stem until CALIBRATE COMPASS displays. 3. Press the set/reset button to start the compass calibration. Or, if the vehicle does not have DIC buttons, press and hold the trip odometer reset stem for two seconds to start the compass calibration. 4. The DIC will display CALIBRATING: DRIVE IN CIRCLES. Drive the vehicle in tight circles at less than 5 mph (8 km/h) to complete the calibration. The DIC will display CALIBRATION COMPLETE for a few seconds when the calibration is complete. The DIC display will then return to the previous menu. 4-57
