Memory Seat and Mirrors (If Equipped)
After adjusting the driver's seat to a comfortable position,
also adjust the interior and exterior mirrors. To program
the memory seat and mirrors, press memory button "M"
and memory button "1" at the same time and hold for
five seconds.
These buttons are located on the outboard side of
the driver's seat. Seat and mirror positions may be
programmed for two additional drivers by repeating
the above steps and pressing memory button "2"
or "3" instead of memory button "1."
If your vehicle is in PARK (P), you can recall mirror and
seating positions by pressing and holding one of the
three memory buttons. This will adjust the seat and
mirrors to where you have previously programmed
them. Seat and mirror movement is immediately stopped
if the memory button is released or if a seat or mirror
control is moved.
If you try to adjust the driver's memory seat and it
doesn't move, try opening the driver's door. This
will reactivate power to the driver's seat. (Power to
the driver's seat "times out" after 30 seconds.
Power to the passenger's seat is always present.)
