For 1990-2009 cars only

Vehicles with the memory package are capable of having the passenger mirror tilt to a preselected position when the vehicle is in R (Reverse). This feature lets the driver view the curb when parallel parking. If further adjustment is needed after the mirror is tilted, the mirror switch may be used. The mirror then returns to this new position when the vehicle is shifted into R (Reverse).

When the vehicle is shifted out of R (Reverse) and a five-second delay has occurred, the passenger side mirror returns to its original position.

Turn this feature on or off through the Driver Information Center (DIC). See DIC Vehicle Personalization for more information.
