Automatic Dimming Rearview Mirror with Compass Your vehicle may have an automatic dimming rearview mirror with a compass. This feature enables the mirror to sense nighttime glare from vehicle headlamps from behind and automatically dim to reduce the glare to a safe level. The automatic dimming feature turns on each time the vehicle is started. Press the OFF button once and the green indicator light located to the left of the button will go out indicating the feature is off. To turn the feature back on, press and release the AUTO button and the green indicator light will come on. Compass Operation Press the on/off button once to turn the compass on or off. When the ignition and the compass feature are on, the compass will show two character boxes for a few seconds. After a few seconds, the mirror will display the current compass direction. Compass Calibration If after a few seconds the display does not show a compass direction, (N for North for example), there may be a strong magnetic field interfering with the compass. Such interference may be caused by a magnetic antenna mount, note pad holder, or similar object. If the letter C appears in the compass window, the compass may need to be reset or calibrated. The mirror can be calibrated by driving the vehicle in circles at 5 mph (8 km/h) or less until the display reads a direction. 145
