SETTING THE DRIVING POSITION
The engine switch must be in the “ON”
position and the selector lever is in the
“P” position.1. Adjust the driver ’s seat and outside rear view mirrors to the desired
position.
2. While pushing the “SET” button, push button “1” or “2” until a beep
is heard.
The system can memorize up to 2 posi-
tions by repeating the above steps. If step
2 is performed when both buttons “1” and
“2” are memorized, the previous position
will be erased and a new position will be
set. To make only slight changes to an already
memorized position, the easiest way is to
first activate the memorized position, then
make the desired changes and perform
step 2 above.RECALLING THE MEMORIZED POSITION
When you push button “1” or “2”, a
beep will sound and the driving posi-
tion will be automatically adjusted to
the position recorded for that button.
The memorized position can be recalled
under the following conditions:
The engine switch is in the “ON posi-
tion and the selector lever is in the “P”
position.
The key is not in the engine switch
and less than 30 seconds have passed
since opening the driver ’s door.

CAUTION
When folding or returning the seats,
observe the following precautions in
order to prevent personal injury:
Make sure that the seat path is
clear before moving the seat. Other-
wise, injury may result from contact
with the seat.
Be careful not to allow hands or
feet to get caught or pinched in the
seat.
When returning the seats to their
original position, make sure the seat

injuries in a sudden braking or a col-
lision.
Do not shift the automatic transmis-
sion selector lever out of “P” with
