The controls for the
memory seat and mirrors
are located on the driver's
door panel, and are used
to program and recall
previous settings that have
been stored.
When your vehicle is in PARK (P) and a memory button
is pressed, a single beep will sound through the audio
system and the memory position will be recalled.
You can also store an exit position for each driver. The
exit position will be set for the most recently selected
driver position (1 or 2). The exit position is programmed
by moving to the desired exit position and then holding
the exit button for five seconds.
The exit position will be recalled when the exit button is
pressed and will correspond to the driving position that
was recalled last.
Note that selecting a new position with the memory
button will change all of the other personalization
features that you have programmed also. See
"Personalization Programming" in the Index for
more information.
Memory seat and exit recall will only work when the
automatic transaxle is in PARK (P).
