UNDERSTANDING THE FEATURES OF YOUR VEHICLE 149 NOTE: If this feature is enabled, the headlamps will be on during the engine pre-heat and cold crank; therefore, it is recommended that the feature be disabled when overnight ambient temperature is at or below 20°F (-7°C) to prevent excessive drain on batteries during cold cranking. • "UNIT IN > US/METRIC" - The EVIC and odometer display can be changed between English and Metric units of measure. To make your selection, press and release the RESET button until "US" or "METRIC" appears. • "COMPASS VARIANCE > 8" - Press the RESET button to change the compass variance setting. For additional information, refer to "Compass Variance" in this section. • "COMPASS CALIBRATE > YES" - Press the RESET button to calibrate the compass. For additional information, refer to "Compass Calibrate" in this section. Compass/Temperature Button Pressing the Compass/Temperature button will return the display to the normal compass/ temperature display. NOTE: Temperature accuracy can be affected from heat soak. For best accuracy, the vehicle should be driven at a speed greater than 25 mph (40 km/h) for several minutes. Automatic Compass Calibration This compass is self-calibrating, which eliminates the need to set the compass manually. 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° turns (in an area free from large metal or metallic objects) until the "CAL" message displayed in the EVIC turns off. The compass will now function normally. 3
