Your vehicle may have an automatic dimming rearview mirror with map lamps.

This mirror automatically changes to reduce glare from headlamps behind you. A time delay feature prevents rapid changing from the day to night positions while driving under lights and through traffic.


Object Number: 807428  Size: B2

The mirror includes two map lamps and an automatic dimming function. There is also an interior console flood lamp located underneath the rearview mirror which remains on at all times.

IO (On/Off): The automatic dimming feature is turned on or off by pressing this button located on the lower part of the mirror. Press and hold the button for up to three seconds to turn this feature on or off.

When cleaning the mirror, use a paper towel or similar material dampened with glass cleaner. Do not spray glass cleaner directly on the mirror housing.
