236 UNDERSTANDING YOUR INSTRUMENT PANEL Compass / Temperature Display The compass readings indicate the direction the vehicle is facing. The EVIC will display one of eight compass readings and the outside temperature. NOTE: • The system will display the last known outside temperature when starting the vehicle and may need to be driven several minutes before the updated temperature is displayed. Engine temperature can also affect the displayed temperature, therefore temperature readings are not updated when the vehicle is not moving. • During snowplow usage on vehicles equipped with outside temperature display, the display may show higher temperatures than the outside ambient temperature. The higher displayed temperature is due to blocked or reduced airflow to the underhood ambient 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.
