SEAT BELTS
Seat belt precautions
Lexus strongly urges that the driver and passengers in the
vehicle be properly restrained at all times with the seat belts
provided. Failure to do so could increase the chance of injury
and/or the severity of injury in accidents.
The seat belts provided for your vehicle are designed for
people of adult size, large enough to properly wear them.
Child. Use a child restraint system appropriate for the child
until the child becomes large enough to properly wear the
vehicle’s seat belts. See “Child restraint” on page 162 for
details.
If a child is too large for a child restraint system, the child should
sit in the rear seat and must be restrained using the vehicle’s
seat belt. According to accident statistics, the child is safer
when properly restrained in the rear seat than in the front seat.
If a child must sit in the front seat, the seat belts should be worn
properly. If an accident occurs and the seat belts are not worn
properly, the force of the rapid inflation of the airbag may cause
death or serious injury to the child.
Do not allow any children to stand up or kneel on either rear or
front seats. An unrestrained child could suffer serious injury or
death during emergency braking or a collision. Also, do not let
the child sit on your lap. Holding a child in your arms does not
provide sufficient restraint.

woman. Lexus recommends the use of a seat belt.
Ask your doctor for specific recommendations. The lap belt
should be worn securely and as low as possible over the hips
and not on the waist.
Injured person. Lexus recommends the use of a seat belt.
Depending on the injury, first check with your doctor for specific
recommendations.
CAUTION
Persons should ride in their seats properly wearing
their seat belts whenever the vehicle is moving.
Otherwise, they are much more likely to suffer serious
bodily injury or death in the event of sudden braking or
a collision.
When using the seat belts, observe the following:
 Use the belt for only one person at a time. Do not use
a single belt for two or more people even children.
 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 you are reclined, the lap belt may slide past
your 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
injury.
 Be careful not to damage the belt webbing or
hardware. Take care that they do not get caught or
pinched in the seat or doors.
 Inspect the belt system periodically. Check for cuts,
fraying, and loose parts. Damaged parts should be
replaced. Do not disassemble or modify the system.
 Keep the belts clean and dry. If they need cleaning,
use a mild soap solution or lukewarm water. Never
use bleach, dye, or abrasive cleaners, or allow them
to come into contact with the belts they may
severely weaken the belts. (See “Cleaning the
interior” on page 467 for instructions.)
 Replace the belt assembly (including bolts) if it has
been used in a severe impact. The entire assembly
should be replaced even if damage is not obvious.

Fastening front, second and third (outside
seats) seat belts
16X017c
Adjust the seat as needed and sit up straight and well back
in the seat. To fasten your belt, pull it out of the retractor
and insert the tab into the buckle.
You will hear a click when the tab locks into the buckle.
The seat belt length automatically adjusts to your size and the
seat position.
The retractor will lock the belt during a sudden stop or on
impact. It also may lock if you lean forward too quickly. A slow,
easy motion will allow the belt to extend, and you can move
around freely. When a passenger’s shoulder belt is completely extended and
is then retracted even slightly, the belt is locked in that position
and cannot be extended.
This feature is used to hold the child
restraint system securely. (For details, see “Child restraint” on
page 162.) To free the belt again, fully retract the belt and then
pull the belt out once more.
If the seat belt cannot be pulled out of the retractor, firmly pull
the belt and release it. You will then be able to smoothly pull
the belt out of the retractor.
CAUTION
 After inserting the tab, make sure the tab and buckle
are locked and that the belt is not twisted.
 Do not insert coins, clips, etc. in the buckle as this
may prevent you from properly latching the tab and
buckle.
 If the seat belt does not function normally,
immediately contact your Lexus dealer. Do not use
the seat until the seat belt is fixed, because it cannot
protect an adult occupant or your child from death or
serious injury.

Improperly seated and/or restrained infants and
children can be killed or seriously injured by the
deploying airbags. An infant or child who is too small
to use a seat belt should be properly secured using
a child restraint system. Lexus strongly
recommends that all infants and children be placed
in the rear seat of the vehicle and properly restrained.
The rear seats are the safest for infants and children.
For instructions concerning the installation of a child
restraint system, see “Child restraint” on page 162.The SRS front airbags are designed to deploy in severe
(usually frontal) collisions where the magnitude and
duration of the forward deceleration of the vehicle
exceeds the designed threshold level.
The SRS front airbags will deploy if the severity of the impact
is above the designed threshold level, comparable to an
approximate 25 km/h (15 mph) collision when the vehicle has
the impact straight into a fixed barrier that does not move or
deform.
However, this threshold velocity will be considerably higher if
the vehicle strikes an object, such as a parked vehicle or sign
pole, which can move or deform on impact, or if the vehicle is
involved in an underride collision (e.g. a collision in which the
front of the vehicle “underrides”, or goes under, the bed of a
truck, etc.).
It is possible that in some collisions where the forward
deceleration of the vehicle is very close to the designed
threshold level, the SRS front airbags and the seat belt
pretensioners may not activate together.
Always wear your seat belts properly.

NOTICE
Do not perform any of the following changes without
consulting your Lexus dealer. Such changes can
interfere with proper operation of the SRS front airbag
system in some cases.
Installation of electronic devices such as a mobile
twoway radio, cassette tape player or CD player.
 Modification of the front end structure.
 Attachment of a grille guard (bull bar, kangaroo bar,
etc.), snowplow, winches or any other equipment to
the front end.
 Repairs made on or near the front fenders, front end
structure, console, steering column, steering wheel,
dashboard near the front passenger airbag or front
seats.

assembly, front airbag sensors, side and curtain shield airbag
sensor assemblies, curtain shield airbag sensor assemblies,
driver’s seat position sensor, driver’s seat belt buckle switch,
front passenger occupant classification system and indicator
light, front passenger’s seat belt buckle switch, seat belt

Improperly seated and/or restrained infants and
children can be killed or seriously injured by the
deploying airbags. An infant or child who is too small
to use a seat belt should be properly secured using
a child restraint system. Lexus strongly
recommends that all infants and children be placed
in the rear seat of the vehicle and properly restrained.
The rear seats are the safest for infants and children.
For instructions concerning the installation of a child
restraint system, see “Child restraint” on page 162.

 Roll sensing of curtain shield airbags off switch
The roll sensing of curtain shield airbags off switch can
turn off the curtain shield airbags in a vehicle rollover.
This switch should only be used in a situation where the
inflation is not desired (such as during extreme offroad
driving).
When you push the roll sensing of curtain shield airbags off
switch for a few seconds with the ignition switch on, the roll
sensing of curtain shield airbags off indicator light comes on
and the roll sensing function is turned off. When you push the
switch again, the indicator light goes off and the roll sensing
function is turned on.
In a severe side impact, the curtain shield airbag on the
impacted side will inflate even if the roll sensing function is
turned off.
If the ignition switch is turned to “ACC” or “LOCK” with the r\
oll
sensing function off and then the ignition switch is turned back
to “ON”, the roll sensing function will be back on automatically.

The SRS side airbag and curtain shield airbag system consists
mainly of the above components, and their locations are
shown in the illustration.
The SRS side airbag and curtain shield airbag system is
controlled by the airbag sensor assembly. The airbag sensor
assembly consists of a safing sensor and airbag sensors. In a severe side impact, the side and curtain shield airbag
sensor and/or the curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain shield airbag inflators.
In a vehicle rollover, the airbag sensor assembly triggers the
curtain shield airbag inflator. At this time a chemical reaction
in the inflators very quickly fills the airbags with non
−toxic gas
to help restrain the forward or lateral motion of the front and
second seat occupants.
When the airbags inflate, they produce a loud noise and
release some smoke and residue along with non −toxic gas.
This does not indicate a fire. This smoke may remain inside
the vehicle for some time, and may cause some minor irritation
to the eyes, skin or breathing. Be sure to wash off any residue
as soon as possible to prevent any potential skin irritation with
soap and water. If you can safely exit from the vehicle, you
should do so immediately.
Deployment of the airbags happens in a fraction of a second,
so the airbags must inflate with considerable force. While the
system is designed to reduce serious injuries, it may also
cause minor burns or abrasions and swelling.
Front seats as well as parts of the front and rear pillars, and roof
side rail may be hot for several minutes, but the airbags
themselves will not be hot. The airbags are designed to inflate
only once.

CAUTION
SRS side airbags and curtain shield airbags inflate with
considerable force. To reduce the possibility of death
or serious injury when they inflate, the driver, front
passenger and rear outboard passengers must:
Wear their seat belts properly.
 Remain properly seated with their backs upright and
against the seats at all times.
16x520a
Do not allow anyone to lean against the door when
the vehicle is in use, since the side airbag and curtain
shield airbag could inflate with considerable speed
and force. Otherwise, he/she may be killed or
seriously injured. Special care should be taken
especially when you have a small child in the vehicle.
 Sit up straight and well back in the seat, distributing
your weight evenly in the seat. Do not apply
excessive weight to the outer side of the seats with a
side airbag,and to the front pillar, rear pillar, and roof
side rail with a curtain shield airbag.
 Improper sitting and wearing of the seat belts may
not retain you inside the vehicle.
