If an abnormal temperature reading is displayed for an extended period of time, please consult your dealer/retailer. Under certain circumstances, a delay in updating the temperature is normal. Compass Calibration The compass may need calibration if: • After several seconds, the display does not show a compass heading (N for North, for example), there may be a strong magnetic field interfering with the compass. Interference can be caused by a magnetic antenna mount, magnetic note pad holder or a similar magnetic item. Passenger Airbag Indicator The vehicle may be equipped with a passenger airbag indicator, on the mirror glass, just above the buttons. If the vehicle has this feature, the mirror displays the word ON, or an airbag symbol in Canada, when the passenger airbag is enabled. For more information, see Passenger Sensing System on page 1-64. • The compass does not display the correct heading and the compass zone variance is set correctly. In order to calibrate, CAL must be displayed in the mirror compass windows. If CAL is not displayed, press and hold O or depending on the mirror, press COMP until CAL displays. The compass can be calibrated by driving the vehicle in circles at 5 mph (8 km/h) or less until the display reads a direction. Cleaning the Mirror Do not spray glass cleaner directly on the mirror. Use a soft towel dampened with water. Compass Compass Operation There is a compass display in the upper right corner of the mirror. Press O or depending on the mirror, press COMP to turn the compass on or off. Compass Variance The mirror is set to zone eight. If you do not live in zone eight or drive out of the area, the compass variance needs to be changed to the appropriate zone. 2-40
