IMPORTANT INFORMATION ABOUTYOUR LEXUS
Occupant restraint systems
Lexus encourages you and your family to take the time to read
Section 1±6 of this Owner's Manual carefully. In terms of
helping you understand how you can receive the maximum
benefit of the occupant restraint systems this vehicle provides,
Section 1±6 of this Owner's Manual is the most important
section for you and your family to read.
Section 1±6 describes the function and operation concerning
seats, seat belts, SRS airbags and child restraint systems of
this vehicle and some potential hazards you should be aware
of. These systems work together along with the overall
structure of this vehicle in order to provide occupant restraint
in the event of a crash. The effect of each system is enhanced
when it is used properly and together with other systems. No
single occupant restraint system can, by itself, provide you or
your family with the equal level of restraint which these
systems can provide when used together. That is why it is
important for you and your family to understand the purpose
and proper use of each of these systems and how they relate
to each other. The purpose of all occupant restraint systems is to help reduce
the possibility of death or serious injury in the event of a
collision. None of these systems, either individually or
together, can ensure that there is no injury in the event of
collision. However, the more you know about these systems
and how to use them properly, the greater your chances
become of surviving an accident without death or serious
injury.
Seat belts provide the primary restraint to all occupants of the
vehicle, and every occupant of the vehicle should wear seat
belts properly at all times. Children should always be secured
in child restraint systems that are appropriate for their age and
size. SRS (Supplemental Restraint System) airbags are, as
their names imply, designed to work with, and be supplemental
to, seat belts and are not substitutes for them. SRS airbags can
be very effective in reducing the risk of head and chest injuries
by preventing contact of the head and chest with interior
portions of the vehicle.
In order to be effective, the SRS airbags must deploy with
tremendous speed. The rapid deployment of the SRS airbags
makes the SRS airbags themselves potential sources of
serious injury if an occupant is too close to an airbag, or if an
object or some part of
his or her body has been placed between
the occupant and the airbag at the time of deployment. This is
just one example of how the instructions in Section 1±6 of this
Owner's Manual will help ensure proper use of the occupant
restraint systems, and increase the safety they can provide to
you and your family in the event of an accident.
Lexus recommends you to read the provisions in Section 1±6
carefully and refer to them as needed during your time of
ownership of this vehicle.

SEATS
While the vehicle is being driven, all vehicle occupants should
have the seatback upright, sit well back in the seat and properly
wear the seat belts provided.
CAUTION
Do not drive the vehicle unless the occupants are
properly seated. Do not allow any passengers to sit
in the luggage compartment or cargo area. Persons
not properly seated and/or not properly restrained by
seat belts can be severely injured in the event of
emergency braking or a collision.
 During driving, do not allow any passengers to stand
up or move around between seats. Otherwise, severe
injuries can occur in the event of emergency braking
or a collision.
FRONT SEATS
(POWER TYPE)
Front seat precautions
Driver seat
CAUTION
The SRS driver airbag deploys with considerable force,
and can cause death or serious injury especially if the
driver is very close to the airbag. The National Highway
Traffic Safety Administration (ªNHTSAº) advises:
Since the risk zone for driver airbag is the first 50Ð75
mm (2Ð3 in.) of inflation, placing yourself 250 mm (10
in.) from your driver airbag provides you with a clear
margin of safety. This distance is measured from the
center of the steering wheel to your breastbone. If you
sit less than 250 mm (10 in.) away now, you can change
your driving position in several ways:
 Move your seat to the rear as far as you can while still
reaching the pedals comfortably.

OCCUPANT RESTRAINT SYSTEMS
95
Slightly recline the back of the seat. Although vehicle
designs vary, many drivers can achieve the 250 mm
(10 in.) distance, even with the driver seat all the way
forward, simply by reclining the back of the seat
somewhat. If reclining the back of your seat makes it
hard to see the road, raise yourself by using a firm,
non±slippery cushion, or raise the seat if your vehicle
has that feature.
 If your steering wheel is adjustable, tilt it downward.
This points the airbag toward your chest instead of
your head and neck.
The seat should be adjusted as recommended by
NHTSA above, while still maintaining control of the foot
pedals, steering wheel, and your view of the instrument
panel controls.
Front passenger seat
CAUTION
The SRS front passenger airbag also deploys with
considerable force, and can cause death or serious
injury especially if the front passenger is very close to
the airbag. The front passenger seat should be as far
from the airbag as possible with the seatback adjusted,
so the front passenger sits upright.
Front seats
CAUTION
The SRS side airbags are installed in the driver and front
passenger seats. Observe the following precautions.
 Do not lean against the front door when the vehicle
is in use, since the side airbag inflates with
considerable speed and force. Otherwise, you may
be killed or severely injured.
 Do not use seat accessories which cover the area
where the side airbags inflate. Such accessories may
prevent the side airbags from activating correctly,
causing death or serious injury.
 Do not modify or replace the seats or upholstery of
the seats equipped with side airbags. Such change
may prevent the side airbag system from activating
correctly, disable the system, or cause the side
airbags to inflate accidentally, resulting in death or
serious injury.

Seat adjustment precautions
CAUTION
Do not adjust the seat while the vehicle is moving as
the seat may unexpectedly move and cause the
driver to lose control of the vehicle.
 Be careful that the seat does not hit a passenger,
luggage or the rear seat.
NOTICE
Do not operate the control switch in more than one
dimension at a time. It may cause electrical overload.

Adjusting seat position
SV16002
Move the control switch in the desired direction.
Releasing the switch will stop the seat in that position. Do not
place anything under the seat, as this might interfere with the
seat movement.
Adjusting seatback angle
SV16003
Move the control switch in the desired direction.
Releasing the switch will stop the seatback in that position.
CAUTION
Avoid reclining the seatback any more than needed. The
seat belts provide maximum protection in a frontal or
rear collision when the driver and the front passenger
are sitting up straight and well back in the seats. If
he/she is reclined, the lap belt may slide past his/her
hips and apply restraint forces directly to the abdomen
or your neck may contact the shoulder belt. In the event
of a frontal collision, the more the seat is reclined, the
greater the risk of death or personal injuly.

CAUTION
To avoid 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 front pas-
senger's seat as a temporary table.
NOTICE
To prevent damage to the seat, avoid putting heavy
loads on the temporary table.

Seat adjustment precautions
CAUTION
Do not adjust the seat while the vehicle is moving as
the seat may unexpectedly move and cause the
driver to lose control of the vehicle.
 Be careful that the seat does not hit a passenger,
luggage or the rear seat.
 After adjusting the seat position, release the lever
and try sliding the seat forward and backward to
make sure it is locked in position.
 After adjusting the seatback, push your body against
the seat to make sure it is locked in position.
 Do not put objects under the seats. Otherwise, the
objects may interfere with the seat±lock mechanism
or unexpectedly push up the seat position adjusting
lever and the seat may suddenly move, causing the
driver to lose control of the vehicle.
 While adjusting the seat, do not put your hands under
the seat or near the moving parts. Otherwise, your
hands or fingers may be caught and injured.
