If your vehicle is equipped with memory mirrors, it will also be capable of performing the curb view assist mirror feature. This feature will allow the driver's and passenger's side mirror to tilt to a factory programmed position when the vehicle is in REVERSE (R). This feature may be useful in allowing you to view the curb when you are parallel parking.

When the vehicle is shifted out of REVERSE (R) and either a thirty-second delay has occurred, the vehicle speed is greater than 8 mph (12 kph), or the ignition is turned to off, the driver's and passenger's side mirror will return to its original position.

This feature can be enabled/disabled through the Driver Information Center (DIC).
