The settings for these features can be saved for up
to two drivers.To store the memory settings, do the following:
1. Adjust the driver’s seat, including the seatback
recliner and lumbar, both of the outside mirrors,
and the adjustable pedals, if equipped, to the
desired position.

page 2-24for more information.
2. Press and hold the 1 or 2 button of the memory
control for three seconds. A double chime will
sound to let you know that the position has been
stored.
To repeat the procedure for a second driver, follow
the preceding steps, but press the other numbered
memory control button.
To recall the memory settings, do one of the following:

is in PARK (P). A single chime will sound and
the memory position will be recalled.

on the remote keyless entry transmitter will recall the
preset driver’s memory seat, mirrors, and adjustable
pedals position. The numbers on the back of the
transmitters, 1 or 2, correspond to the numbers

key in the ignition will recall the driver’s memory seat,
mirrors, and adjustable pedals positions.
