Conditions for memorized position activation

Engine switch in “IG−ON” mode and selector lever in ”P”
position, with the vehicle stopped.
 Engine switch in “OFF” mode and within 30 seconds of
opening driver’s door.
The memorized position can be activated, except for the tilt
and telescopic steering.
If any driving position memory switch is pushed while one of
the memorized driving position profiles is being activated, the
operation will stop.
To activate the system, push the desired button (“1”, “2” or \
“3”)
again.
The driving position memory control system cannot be
operated while the vehicle is moving.
If the vehicle’s battery is disconnected, the computer’s
memory will be erased and the memorized positions will have
to be set again.
CAUTION
 Do not start the vehicle while the adjustments are
being made.
 Take care not to select the wrong button, or the seat
could strike the rear passenger or hit your body
against the steering wheel. If this happens, you can
stop the movement by pressing another driving
position memory switch.
MEMORY RECALL FUNCTION
You can recall the memorized position using the entry
function or wireless remote control.
If you unlock the door using the entry function or wireless
remote control, the memorized seat position is recalled when
the driver’s door is opened. The memorized steering wheel
position will be recalled when you push the engine switch.
This function can be used after setting by the following
procedure.
Setting the driving position onto the electronic key
The driver’s door must be closed with the engine switch turned
off.
1. Push and hold the previously memorized driving position
button “1”, “2” or “3”.
2. While depressing the button above, push and hold the
“LOCK” or “UNLOCK” button on the electronic key until a beep
sounds.
If you wish to set other driv ing position, repeat the above
procedure. The previous setting will be erased and the new
position will be set.
Resetting the driving position on the electronic key
The driver’s door must be closed with the engine switch turned
off.
1. Push and hold the “SET” button.
2. Push and hold the “LOCK” or “UNLOCK” button on the

FRONT PASSENGER SEAT
POSITION MEMORY SYSTEM
A microcomputer can memorize the position of the front
passenger seat. Three different seat position profiles can be
entered into the computer’s memory.
Recording a seat position in the computer’s memory can only
be done when the engine switch is selected in “IG −ON” mode
and the selector lever is in the ”P” position.
Setting the front passenger seat position
G16123
1. Adjust the front passenger seat to the desired position.
2. While pushing the ”SET” button, push button ”1”,”2” or
“3” until the signal beeps. The beep sound means that the positions are recorded in the
computer’s memory.
By repeating these two steps
and pressing the remaining
button, the seat position for another passenger can be
recorded.
To set a new memorized position, select the desired position
and perform step 2. The previous memory will be erased and
the 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
G16124
When you push button ”1”, ”2” or “3”, the seat positio\
n
will be automatically adjusted to the position recorded for
that button.

STEERING WHEEL AND MIRRORS

Automatic tilt away*
G17003
When the engine switch is off, the steering column moves
forward away from the driver and also tilts up for easy exit
and entry.
When you turn on the engine switch, the steering column
returns to the previously set position.
NOTE:
*This feature can be deactivated.
Ask your Lexus dealer for details.
OUTSIDE REAR VIEW MIRRORS
G17004
Adjust the mirror so that you can just see the side of your
vehicle in the mirror.
Be careful when judging the size or distance 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 if seen in a normal
flat mirror.
When the inside rear view mirror darkens in ”AUTO” mode, the
outside rear view mirrors also darken to reduce the reflection
of the headlights of the following vehicle. For details, see
”Inside rear view mirror” on page 213.
When you push the rear window and outside rear view mirror
defogger switch, the heater panels in the outside rear view
mirrors will quickly clear the mirror surface. (See “Rear window
and outside rear view mirror defogger switch” on page 58.)

STEERING WHEEL AND MIRRORS

The power rear view mirrors can be adjusted when the engine
switch is in “ACC” or “IG−

CAUTION
To reduce the chance of injury in case of an accident or
a sudden stop, keep the switch box closed when not in
use while driving.
NOTICE
If ice should jam the mirror, do not operate the control
or scrape the mirror face. Use a spray deicer to free the
mirror.
Folding rear view mirrors
The power rear view mirror folding switch is located in the
switch box.
G17014
Push the button to use the switch box and then push the
folding switch.

the switch again, the mirrors will be extended to their original
position. After adjustment, be sure to close the switch box to
its original position.
The engine switch must be selected in “ACC” or “IG −ON”
mode.

vehicle in the mirror.
Pushing the “AUTO” button changes the mode between
”AUTO” and ”DAY”.
The indicator comes on when the ”AUTO” mode is selected.
”DAY” mode: The mirror surface is normal.
”AUTO” mode: If the mirror detects light from the
headlights of the vehicle behind you, the mirror surface
darkens slightly to reduce the reflected light.
When the inside rear view mirror surface changes, the outside
rear view mirror surfaces will also become darker.
When the engine switch is selected in “IG −ON” mode, the
inside rear view mirror always turns on in the ”AUTO” mode.

Pushing the “AUTO” button for longer than 3 seconds
turns on or off the compass display.
The compass may not show the correct direction in the
following conditions:

The vehicle is stopped immediately after turning.
The compass does not adjust while the vehicle is stopped.
 The engine switch is turned off immediately after turning.
 The vehicle is on an inclined surface.
 The vehicle is in a place where the earth’s magnetic field is
subject to interference by artificial magnetic fields
(underground parking, under a steel tower, between
buildings, roof parking, near a crossing, near a large
vehicle, etc.).
 The vehicle is magnetized. (There is a magnet or a metal
object near the inside rear view mirror.)
 The battery has been disconnected.
 Any door is open.
If the deviation is small, the compass works to calibrate the
direction automatically while the vehicle is in motion.
For obtaining additional precision or for complete calibrating,
see “CALIBRATING THE COMPASS” below.
NOTICE
Do not put magnets or a metal object near the inside rear
view mirror. Doing this may cause malfunction of the
compass sensor.
CALIBRATING THE COMPASS (deviation calibration)
The direction display on the compass deviates from the true
direction determined by the earth’s magnetic field. The
amount of deviation varies according to the geographic
position of the vehicle.
To adjust for this deviation, stop the vehicle and push the
“AUTO” button for longer than about 6 seconds until the zone
number (1 −15) appears on the display. Then push the button
again, referring to the following map to select the number of the
zone where the vehicle is.
