Automatic Dimming Mirror

The vehicle has an automatic dimming outside mirror on the driver side. The mirror adjusts to glare from headlights behind you.

Reverse Tilt Mirrors

If equipped with memory seats, the passenger and/or driver side mirror tilts to a preselected position when the vehicle is in R (Reverse), if enabled. This allows you to view the curb when parallel parking.

The mirror(s) return to the original position when:

  • The vehicle is shifted out of R (Reverse) or remains in R (Reverse) for about 30 seconds.
  • The ignition is off.
  • The vehicle moves in R (Reverse) above a set speed.

To turn this feature on or off, refer to Vehicle Personalization.
