You can use the seatback as a temporary
table only when the vehicle is stopped.
CAUTION
To avoid death or serious injury:
Do not set up the seatback table
while the vehicle is moving.
Do not sit on the folded seatback.
Make sure the front passenger ’s
seat is securely locked in sliding
position when you set the seat as
a temporary table.
NOTICE
To prevent damage to the seat, avoid
putting heavy loads on  the temporary
table.
This system can memorize  the position
of the driver’s seat and outside rear
view mirrors, and recall them at the
touch of a button.
Buttons “1” and “2” can memorize two
separate positions.

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.

To adjust the steering wheel position,
push down the lock release lever. Then
tilt the steering wheel to the desired
angle, push or pull it to the desired
steering column length and pull up the
lock release lever.
CAUTION
Do not adjust the steering wheel
while the vehicle is moving. Doing
so may cause the driver to mishan-
dle the vehicle and an accident may
occur resulting in death or serious
injuries.
After adjusting the steering wheel,
try moving it up and down or for-
ward and rearward to make sure it
is locked in position.
Adjust  the mirror so that you can just
see the side of your vehicle in the mir-
ror.
Be careful when judging the size or dis-
tance of any object seen in the outside
rear view mirror on the passenger ’s side
because it is a convex mirror. Any object
seen in a convex mirror will  look smaller
and farther away than when seen in a flat
mirror.

Vehicles with the auto anti−glare inside
rear view mirror—On some models, when
the inside rear view mirror surface dark-
ens in “AUTO” mode, the outside rear
view mirror surface also darkens  to re-
duce the reflection of the headlights of the
vehicle behind you.  (For details,  see “Auto
anti −glare inside rear view mirror” on page
167 in this Section.)
On some models, when you push the rear
window defogger  switch, the heater panels
in the outside rear view mirrors will quick-
ly clear the mirror surface. (See “Rear
window and outside rear view mirror de-
foggers and windshield wiper  de −icer” on
page 184 in Section 1 −5.)
CAUTION
Do not adjust the mirror while the
vehicle is moving. Doing so may
cause the driver to mishandle the
vehicle and an accident may occur
resulting in death or  serious inju-
ries.
On some models, since the mirror
surfaces can get hot, do not touch
them when the defogger switch is
on.

tion memory system” on page 65 in Sec-
tion 1 −3.
