Memory Seat
These buttons are used to program and recall the
memory settings for the driver's seat and both the
driver's and the passenger's outside mirrors and the
radio station presets. The seat, mirror positions and
radio station presets can be personalized for both
driver 1 and driver 2. Driver 1 or driver 2 corresponds
to the memory buttons labeled 1 and 2 on the driver's

of each keyless entry transmitter.
The controls for the
memory function are
located on the driver's
door trim panel.
