CAUTION
When using the lower anchorages for the child
restraint system, be sure that there are no irregular
objects around the anchorages or that the seat belt is
not caught.
 Push and pull the child restraint system in different
directions to be sure it is secure. Follow all the
installation instructions provided by its
manufacturer.
 When using the lower anchorages for a child restraint
system, ensure that the seat is moved to the
rearmost position, with the seatback close to the
child restraint system.
 After securing the child restraint system, never slide
the seat.
DRIVING POSITION MEMORY SYSTEM
A microcomputer will memorize the position of the driver’s
seat, the height of the head restraint of the driver’s seat, the
seat cushion length of the driver’s seat, the height of the
shoulder belt anchor of the driver’s seat belt, and the positions
of the tilt and telescopic steering, and outside rear view mirrors.
Three dif ferent driving position profiles can be entered into the
computer’s memory.
Recording a driving position in the computer’s memory can
only be done when the ignition switch is in the “ON” position
and the selector lever is in the “N” or “P” position.
Setting the driving position
16L299
1. Adjust the driver’s seat, driver’s head restraint height
and seat cushion length, driver’s shoulder belt anchor, tilt
and telescopic steering and outside rear view mirrors to
the desired position.

OCCUPANT RESTRAINT SYSTEMS
222Conditions for memorized position activation

Ignition switch “ON” and selector lever in “N” or “P” position
with the vehicle stopped.
All parts of the memorized positions can be activated.
 Ignition switch off 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.
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 CALL SYSTEM USING A SMART KEY
This system allows you to adjust the driver’s seat, the
driver’s head restraint height, driver’s seat cushion
length, the height of the shoulder belt anchor of the
driver’s seat belt and outside rear view mirrors to the
memorized position when you open the driver’s door after
unlocking it with a smart key. And when you push the
ignition switch, the tilt and telescopic steering is adjusted.
To activate this system, the ID of the smart key needs to
be registered in the memory button.
Registering the smart key ID code
Before the registration of the ID of the smart key, the driving
position must be memorized in the memory button.
When registering, the driver’s door must be closed with the
ignition switch in the “OFF” position.
1. Keep the smart key in possession, select a button in
which you want to record the ID of the key from buttons
“1”, “2” and “3” and push it.
2. Push the “LOCK” or “UNLOCK” button on the smart
key for about one second with button “1”, “2” or “3” held\
down.
When the registration is completed, one beep sounds. If the
key has already been registered, the previous memory will be
erased. If the same driving position profile for the same key is
registered in another button, that memory will also be erased.

ELECTRONICALLY MODULATEDAIR SUSPENSION
This electronically modulated air suspension adjusts the
damping effect on the shock absorbers and the vehicle
height. This adjustment is automatically made in
response to the driving conditions to provide good riding
comfort and stability in all driving conditions.
(a) Vehicle height adjustment
31L343
 1High position 2Normal position
This system maintains a stable vehicle height, regardless
of occupants and luggage weight. Select either of the
following modes using a selector switch. Normal mode:
Suitable for driving on roads with a normal
surface.
High mode: Suitable for driving on rough roads which are
unsurfaced or continually bumpy.
The damping effect is set slightly firmer in the high mode. So
you may feel the vibration of the vehicle compared to in the
normal mode. However, this does not mean a malfunction in
the system. We recommend you use a normal mode in normal
driving.
To change the mode, push the selector switch.
Normal mode:
The vehicle height remains at normal height at all driving
speeds.
High mode:
The vehicle height switches between the following two vehicle
heights according to the driving conditions:
Vehicle height
Driving condition
NormalMedium and high speed driving
HighLow speed driving

The indicator light shows the high mode is selected.
CAUTION
For vehicles equipped with the height control switch, be
sure to turn the ignition switch off before jacking. If this
is not done, the vehicle height adjustment function will
operate, which may cause an accident.
Malfunction warning
If the system is malfunctioning, “Height Hi” appears on the
multi−information display, the master warning light comes on
and a warning tone sounds. Although it is no problem to
continue driving, have the s ystem checked by your Lexus
dealer at the first opportunity.
(b) Damping mode selection
31L144b
 1 Sports position 2Normal position
The damping effect on the shock absorbers is adjusted.
Select either of the following modes using a selector
switch.
Sports mode: Suitable for sporty type driving, such as on
winding mountain roads and high speed driving.
Normal mode: Suitable for ordinary driving.
To turn on the sports mode, push the selector switch on the
“SPORT” side. The indicator comes on in the instrument
cluster and a stronger damping effect than that in normal mode
is automatically provided.
To change to the normal mode, push the switch to the “NORM”
side.

Antilock brake system is not designed to shorten the
stopping distance: Always drive at a moderate speed
and maintain a safe distance from the vehicle in front of
you. Compared with vehicles without an antilock
brake system, your vehicle may require a longer
stopping distance in the following cases:
Driving on rough, gravel or snowcovered roads.
 Driving with tire chains installed.
 Driving over the steps such as the joints on the road.
 Driving on roads where the road surface is pitted or
has other differences in surface height.
Install all 4 tires of specified size at appropriate
pressure: The antilock brake system detects vehicle
speeds u sing the speed sensors for respective wheels’
turning speeds. The use of tires other than specified
may fail to detect the accurate turning speed resulting
in a longer stopping distance.“ABS” warning light
31L350
 1 U.S.A. 2Canada
The light comes on when the ignition switch is turned to the
“ON” position. If the anti−lock brake system and the brake
assist system work properly, the light turns off after a few
seconds. Thereafter, if either of the systems malfunctions, the
light comes on again.
When the “ABS” warning light is on (and the brake system
warning light is off), the anti −lock brake system, the brake
assist system, the traction control system and/or the vehicle
stability control system do/does not operate, but the brake
system still operates conventionally.
When the “ABS” warning light is on (and the brake system
warning light is off), the anti− lock brake system does not
operate so that the wheels could lock up during a sudden
braking or braking on slippery road surfaces.
