Auto-Dimming Mirror (If Equipped)
Note: Do not block the sensors on the front and back of the mirror.
Mirror performance may be affected. A rear center passenger or raised
rear center head restraint may also block light from reaching the sensor.
The mirror will dim automatically to reduce glare when bright lights are
detected from behind your vehicle. It will automatically return to normal
reflection when you select reverse gear to make sure you have a clear
view when backing up.
