The vehicle may have an automatic dimming mirror with compass and temperature display.

Automatic Dimming Mirror Operation

Automatic dimming reduces the glare of lights from behind the vehicle. The dimming feature comes on and the indicator light illuminates each time the vehicle is started.

(On/Off) : Press to turn the dimming feature on or off.

Temperature Display

(Compass/Temperature): Press to turn the display on or off.

To alternate the temperature reading between Fahrenheit and Celsius, press and hold for approximately three seconds until the display blinks F and C. Stop pressing and holding this button once the desired unit displays. After approximately five seconds of inactivity, the display stops blinking and displays the last selection made.

If an abnormal reading is displayed, see your dealer/retailer.

Cleaning the Mirror

Do not spray glass cleaner directly on the mirror. Use a soft towel dampened with water.
