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
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 (“NHTSA”) advises:
Since the risk zone for driver airbag is the first 5075
mm (23 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.
 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,
nonslippery cushion, or raise the seat if your vehicle
has that feature.

OCCUPANT RESTRAINT SYSTEMS
103
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.
 Do not use seat accessory, such as a cushion or seat
cover, that covers the front seat, or do not modify or
replace the upholstery of the front seat. Such
accessories or changes may prevent the front
passenger airbag system from activating correctly,
disable the system or cause the front passenger
airbag to inflate accidentally, resulting in death or
serious injury.
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 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.

ARMREST
16X183b
To use the armrest, pull it down as shown above.
NOTICE
To prevent damage to the armrest, avoid putting heavy
loads on it.
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.

If the seat belt extender has been connected to the
driver’s seat belt buckle without the driver actually
wearing the seat belt, the SRS driver’s airbag system
will judge that the driver is wearing it. In this case, the
driver’s airbag may not activate correctly, causing
death or serious injury in the event of collision. Be
sure to wear the seat belt with the seat belt extender.
Make sure the front passenger occupant
classification indicator li ght indicates “ON” when
using the seat belt extender for the front passenger
seat. If the indicator light indicates “OFF”,
disconnect the extender t ongue from the seat belt
buckle, then reconnect the seat belt. Reconnect the
seat belt extender after making sure the indicator
light indicates “ON”. If you use the seat belt extender
while the indicator light indicates “OFF”, the front
passenger airbag and side airbag on the front
passenger side may not ac tivate correctly, which
could cause death or serious injury in the event of
collision.
 Do not use the seat belt extender if it is not absolutely
necessary.
 Do not use the seat belt extender when installing a
child restraint system on the front or rear passenger
seat. If installing a child restraint system with the
seat belt extender connected to the seat belt, the seat
belt will not securely hold the child restraint system,
which could cause death or serious injury to the child
or other passengers in the event of collision.

To connect the extender to the seat belt, insert the tab into
the seat belt buckle so that the “PRESS” signs on the
buckle release buttons of the extender and the seat belt
are both facing outward as shown.
You will hear a click when the tab locks into the buckle.
When releasing the seat belt, press on the buckle release
button on the extender, not on the seat belt. This helps prevent
damage to the vehicle interior and extender itself.
As far as the seat belt extender on the front passenger side is
concerned, do not fail to disconnect the extender from the seat
belt after the above operation in order to activate the front
passenger airbag correctly when getting into the vehicle next
time.
When not in use, remove the extender and store in the vehicle
for future use.
CAUTION
 After inserting the tab, make sure the tab and buckle
are locked and that the lap and shoulder portions of
the belt and the seat belt extender are 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.

Seat belt pretensioners
16X620
The driver and front passenger seat belt pretensioners are
designed to be activated in response to a severe frontal
impact or a vehicle rollover.
When the sensor detects a severe frontal impact or a vehicle
rollover, the front seat belts are quickly drawn back by the
retractor so that the belts snugly restrain the occupants.
The front passenger’s seat belt pretensioner will not activate
if no passenger is detected in the front passenger seat by the
front passenger occupant classification system. However, the
front passenger’s seat belt pretensioner may activate if
luggage is put on the seat, or the seat belt is buckled up
regardless of the presence of an occupant in the seat. (As for
the front passenger occupant classification system, see page
157.)
The seat belt pretensioners and SRS airbags may not operate
together in all collisions.
16x503b
 Roll sensing of curtain shield airbags off indicator light
The seat belt pretensioners will not operate in a vehicle rollover
if the roll sensing of curtain shield airbags off indicator light is
on. For details, see “Roll sensing of curtain shield airbags off
switch” on page 45.

OCCUPANT RESTRAINT SYSTEMS
131
CAUTION
Make sure the roll sensing of curtain shield airbags
off indicator light is not on.
 When the roll sensing of curtain shield airbags off
switch is turned on (and the roll sensing of curtain
shield airbags off indicator light is on), the seat belt
pretensioners will not operate in a vehicle rollover
and turning off the seat belt pretensioners can
reduce the occupant protection which your vehicle
safety systems can provide to you in certain
accidents and increase the likelihood of death or
serious personal injuries.

The seat belt pretensioner system consists mainly of the
above components, and their locations are shown in the
illustration.
The seat belt pretensioners are controlled by the airbag sensor
assembly. The airbag sensor assembly consists of a safing
sensor and airbag sensor.
When the seat belt pretensioners are activated, an operating
noise may be heard and a small amount of non −toxic gas may
be released. This does not indicate that a fire is occurring. This
gas is normally harmless.
Once the seat belt pretensioners have been activated, the seat
belt retractors remain locked.

CAUTION
Do not modify, remove, strike or open the seat belt
pretensioner assemblies, airbag sensor or
surrounding area or wiring. Failure to follow these
instructions may prevent the seat belt pretensioners
from activating correctly, cause sudden operation of
the system or disable the system, which could result
in death or serious injury.
 Do not use tires or wheels other than the
manufacturer’s recommended size. Such a use may
cause the curtain shield airbags and seat belt
pretensioners to inflate accidentally, resulting in
death or serious injury. For details, see “Checking
and replacing tires” on page 438.
 Do not place luggage heavier than specified on the
roof luggage carrier. Such luggage may cause the
curtain shield airbags and seat belt pretensioners to
inflate accidentally, resulting in death or serious
injury. For details, see “Roof luggage carrier” on
page 88.
 Do not modify or change the suspension system.
Such changes may cause the curtain shield airbags
to inflate accidentally, resulting in death or serious
injury.
Failure to follow these instructions can result in death
or serious injury. Consult your Lexus dealer before
performing any repair and modification.
NOTICE
Do not perform any of the following changes without
consulting your Lexus dealer. Such changes can
interfere with proper operation of the seat belt
pretensioners in some cases.
 Installation of electronic devices such as a mobile
twoway radio, cassette tape player or CD player.
 Repairs on or near the seat belt retractor assemblies.
 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 or console.
