UNDERSTANDING YOUR INSTRUMENT PANEL 233 temperature sensor caused by the snowplow. In addition, on vehicles equipped with Automatic Temperature Control (ATC), it is suggested that the interior cabin temperature be manually controlled should the system not perform as desired while in automatic mode. Both the outside temperature display and ATC operation will return to normal when the snowplow is removed. Automatic Compass Calibration This compass is self-calibrating, which eliminates the need to manually reset the compass. When the vehicle is new, the compass may appear erratic and the EVIC will display CAL until the compass is calibrated. You may also calibrate the compass by completing one or more 360-degree turns (in an area free from large metal or metallic objects) until the CAL indicator displayed in the EVIC turns off. The compass will now function normally. NOTE: A good calibration requires a level surface and an environment free from large metallic objects such as buildings, bridges, underground cables, railroad tracks, etc. Manual Compass Calibration If the compass appears erratic and the CAL indicator does not appear in the EVIC display, you must put the compass into the Calibration Mode manually, as follows: 1. Turn ON the ignition switch. 2. Press the UP or DOWN button until the System Setup (Customer-Programmable Features) menu is reached, then press the SELECT button. 3. Press the DOWN button until "Calibrate Compass" is displayed in the EVIC. 4. Press and release the SELECT button to start the calibration. The "CAL" indicator will be displayed in the EVIC. 4
