SeeOutside Power Mirrors on page 2-42for more
information.
Not all mirrors will have the ability to save and
recall the mirror positions.
2. Press and hold button 1 until two beeps let you
know that the position has been stored.
A second seating and mirror position can be
programmed by repeating the above steps and pressing
button 2.

Using the Remote Keyless Entry (RKE) transmitter to
enter your vehicle with the remote recall memory feature
on causes automatic seat and mirror adjustment.
There is no adjustment when the position has not been
changed by another seating position or the easy exit

To stop recall movement of the memory feature at any

buttons, or power mirror buttons.
If something has blocked the driver’s seat while recalling
a memory position, the driver’s seat recall may stop
working. If this happens, press the appropriate control
for the area that is not recalling for two seconds,
after the obstruction is removed. Then try recalling the
memory position again by pressing the appropriate
memory button. If the memory position is still not being
recalled, see your dealer/retailer for service.Easy Exit Seat
The control for this feature is located on the driver’s
door panel between buttons 1 and 2.
With the vehicle in PARK (P), the exit position can be
recalled by pressing the exit button. You will hear
a single beep. The driver’s seat will move back.
If the easy exit seat feature is on in the Driver
Information Center (DIC), automatic seat movement will
occur when the key is removed from the ignition.
