If your vehicle is equipped with memory mirrors, it is capable of performing the park tilt mirror feature. This feature allows the driver and passenger side mirror to tilt to a factory programmed position when the vehicle is in R (Reverse). This feature may be useful in allowing you to view the curb when you are parallel parking.
When the vehicle is shifted out of R (Reverse) and either a five-second delay has occurred, or the ignition is turned to LOCK/OFF, the driver and passenger side mirror will return to its original position.
This feature can be enabled/disabled through the Driver Information Center (DIC). See DIC Vehicle Customization for more information.
