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 passengers to sit in the
luggage compartment or cargo area. Persons not
properly seated and/or properly restrained by seat
belts can be severely injured in the event of
emergency braking or a collision.
During driving, do not allow passengers to stand up
or move around between seats. Otherwise, severe
injuries can occur in the event of emergency braking
or a collision.
Front seat precautions
Driver seat
CAUTION
The 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 (ºNHTSAº) advises:
Since the risk zone for driver airbag is the first 50±75
mm (2±3 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,
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 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 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 parts
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
seats with side airbags. Such changes may prevent
the side airbags from activating correctly, disable the
system, or cause the side airbags to inflate
accidentally, resulting in death or serious injury.

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 ºChild restraintº on page 111 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. Do not let the child sit on your lap. It does not provide
sufficient restraint. If an accident occurs and the seat belts are
not worn properly, the force of the rapid inflation of the airbag
may cause severe injury to the child.
Do not allow the child 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.
Pregnant 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 seatbacks too much. The seat
belts provide maximum protection when the
seatbacks are in the upright position. (See
ºAdjusting seatback angleº on page 77.)
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.

Front seat belt pretensioners
16G132b
The driver and front passenger's seat belt pretensioners
are designed to be activated in response to a severe
frontal impact.
When the airbag sensor detects the shock of a severe frontal
impact, the front seat belts are quickly drawn back by the
retractor so that the belts snugly restrain the front seat
occupants.
The front passenger seat belt pretensioner will not activate if
there is no passenger sitting in the front passenger seat.
However, the front passenger seat belt pretensioner may
activate if luggage is put in the seat, or the seat belt is buckled
up regardless of the presence of the occupant in the seat.
Collisions occurring at certain speeds and angles may cause
the seat belt pretensioners and SRS airbags not to operate all
together.
16G022
This indicator comes on when the ignition key is turned to
the ªONº position. It goes off after about 6 seconds. This
means the front seat belt pretensioners are operating
properly.
This warning light system monitors the airbag sensor
assembly, front airbag sensors, side and curtain shield airbag
sensors, occupant detection sensor, seat belt buckle switch,
front seat belt pretensioner assemblies, inflators, warning light,
interconnecting wiring and power sources. (For details, see
ºService reminder indicators and warning buzzersº on page
40.)

2Front seat belt pretensioner assembly
3SRS warning light
4Airbag sensor assembly
5Occupant detection sensor
6Seat belt buckle switch
The front seat belt pretensioner system consists mainly of the
above components, and their locations are shown in the
illustration.
The front seat belt pretensioners are controlled by the airbag
sensor assembly. The airbag sensor assembly consists of a
safing sensor and airbag sensor.
When the front seat belt pretensioners are activated, an
operating noise may be heard and a small amount of
smoke±like gas may be released. This gas is harmless and
does not indicate that a fire is occurring.
Once the front seat belt pretensioners have been activated, the
seat belt retractors remain locked.
CAUTION
Do not modify, remove, strike or open the front seat belt
pretensioner assemblies, airbag sensor or surrounding
area or wiring. Doing any of these may cause sudden
operation of the front seat belt pretensioners or disable
the system, which could result in death or serious
injury.
Failure to follow these instructions can result in death
or serious injury. Consult your Lexus dealer about any
repairs and modifications.
NOTICE
Do not perform any of the following changes without
consulting your Lexus dealer. Such changes can
interfere with proper operation of the front seat belt
pretensioners in some cases.
Installation of electronic devices such as a mobile
two±way radio, cassette tape player or compact disc
player.
Repairs on or near the front seat belt retractor
assemblies.
Modification of the suspension system.
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.

SRS AIRBAGS
The SRS (Supplemental Restraint System) airbags are
designed to provide further protection for the driver and
front passenger in addition to the primary safety
protection provided by the seat belts.
16G020c

Driver and front passenger airbags
In response to a severe frontal impact, the driver and front
passenger airbags work together with the seat belts to
help reduce injury by inflating. The driver and front
passenger airbags help to reduce injuries mainly to the
driver's or front passenger's head or chest directly hitting
the steering wheel or dashboard.
The front passenger airbag will not activate if there is no
passenger sitting in the front passenger seat. However, the
front passenger airbag may deploy if luggage is put in the seat,
or the seat belt is buckled up regardless of the presence of the
occupant in the seat.Your vehicle is equipped with a crash sensing and diagnostic
module, which will record the use of the seat belt restraint
system by the driver when the front airbags are inflated.
Be sure to wear your seat belt properly.
CAUTION
The driver or front passenger who is too close to the
steering wheel or dashboard during airbag deployment
can be killed or seriously injured. Lexus strongly
recommends that:
The driver sit as far back as possible from the
steering wheel while still maintaining control of the
vehicle.
The front passenger sit as far back as possible from
the dashboard.
All vehicle occupants be properly restrained using
the available seat belts.

16G021b

Side airbags
In response to a severe side impact, the side airbags for
the driver or front passenger work together with the seat
belts to help reduce injury by inflating. The side airbags
help to reduce injuries mainly to the driver's or front
passenger's chest.
The side airbag on the passenger seat will not activate if there
is no passenger sitting in the front passenger seat. However,
the side airbag on the passenger seat may deploy if luggage
is put in the seat, or the seat belt is buckled up regardless of
the presence of the occupant in the seat.
Your vehicle is equipped with a crash sensing and diagnostic
module, which will record the use of the seat belt restraint
system by the driver when the side airbags are inflated.
Be sure to wear your seat belt properly.
CAUTION
The side airbags inflate with considerable force. To
avoid potential death or serious injury when they inflate,
the driver and front passenger must:
Wear their seat belts properly.
Remain properly seated with their back upright and
against the seat at all times.
16G143d

Curtain shield airbags
In response to a severe side impact, the curtain shield
airbags for the driver or front passenger work together
with the seat belts by inflating to help reduce injury mainly
to the driver's or front passenger's head.
The curtain shield airbag is activated even with no passenger
in the front seat.
Be sure to wear your seat belt properly.
