The vehicle may have an automatic dimming rearview mirror with map lamps and HomeLink® Transmitter buttons. For more information about this feature, see HomeLink® Wireless Control System .

While sitting in a comfortable driving position, adjust the mirror so you can see clearly behind your vehicle. Grip the mirror in the center to move it up or down and side to side.

Mirror Operation

The 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.

(On/Off): The automatic dimming feature is automatically activated when the vehicle is started. 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.

(Indicator Light): This light will turn on when the automatic dimming feature is on.

(Map Lamps): Press this button to turn the map lamps on and off.

Press the two outside mirror buttons to light the transmission positions on the console.

Cleaning the Mirror

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