Park Tilt Mirrors
If the vehicle has the memory package, the outside mirrors have a park tilt feature. This feature tilts the outside mirrors to a preselected position when the vehicle is in R (Reverse). This allows the driver to view the curb for parallel parking.
The passenger and/or driver mirror returns to its original position when the vehicle is shifted out of R (Reverse), or the ignition is turned off or to OFF/LOCK.
This feature can be turned on or off through the Driver Information Center (DIC). See Vehicle Personalization (With DIC Buttons) on page 5‑46 for more information.
