Reducing impact to the occupants in a collision

Reducing impact to passengers in a collision

Seat belt pretensioners

When the vehicle is subjected to a severe frontal or side impact or rollover, the
pretensioners retract the seat belts of the front seats and rear outer seats to
securely restrain the occupants.

The pretensioners will not operate in minor frontal or side impacts, or rear impacts.

INFORMATION

■

Replacing the belt after the pretensioner has been activated

If the vehicle is involved in multiple collisions, the pretensioner will activate for the first
collision, but will not activate for the second or subsequent collisions.

■

PCS-linked control

If the PCS (Pre-Collision System) determines that the possibility of a collision with a
vehicle is high, the seat belt pretensioners will be prepared to operate.

WARNING

■

Seat belt pretensioners

Observe the following precautions to reduce the risk of injury in the event of sudden
braking or an accident. Failure to do so may result in death or serious injury.

●

Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor from detect-
ing the passenger’s weight properly. As a result, the seat belt pretensioner for the front
passenger’s seat may not operate in the event of a collision.

●

If a pretensioner has operated, the SRS warning light will illuminate.
In this situation, the seat belt cannot be used and must be replaced by your Lexus
dealer.

SRS airbags

The SRS airbags deploy when the vehicle is subjected to certain types of severe
impact that may cause significant injury to the occupants. The airbags work togeth-
er with the seat belts to help reduce the risk of death or serious injury.

SRS driver airbag/front passenger airbag

Help reduce impact to the head and chest of the driver and front passenger

SRS knee airbags

Help reduce impact to the driver and front passenger

SRS seat cushion airbags

●

Helps reduce impact to the front passenger

●

Help restrain the occupant of a rear seat

SRS side airbags

●

vehicle rollover

Your vehicle is equipped with ADVANCED AIRBAGS designed based on US
motor vehicle safety standards (FMVSS209). The airbag sensor assembly (ECU)
controls airbag deployment based on information obtained from the sensors, etc.,

shown in the system components diagram above. This information includes crash
severity and occupant information. As the airbags deploy, a chemical reaction in
the inflators quickly fills the airbags with non-toxic gas to help restrain the motion of
the occupants.

INFORMATION

■

If the SRS airbags deploy (inflate)

●

Slight abrasions, burns, bruising, etc., may be sustained from SRS airbags, due to the
extremely high speed of deployment (inflation) by hot gases.

●

A loud noise and white powder will be emitted.

●

Parts of the airbag module (steering wheel hub, airbag cover and inflator) as well as
the parts around the airbags may be hot for several minutes. The airbag itself may also
be hot.

●

The windshield may crack.

●

All of the doors will be unlocked.

●

The brakes and stop lights will be controlled automatically.

●

The interior lights will turn on automatically.

●

The emergency flashers will turn on automatically.

●

Fuel supply to the engine will be stopped.

●

For Safety Connect subscribers, if any of the following situations occur, the system is
designed to send an emergency call to the response center, notifying them of the vehi-
cle's location (without needing to push the [SOS] button) and an agent will attempt to
speak with the occupants to ascertain the level of emergency and assistance required.
If the occupants are unable to communicate, the agent automatically treats the call as
an emergency and helps to dispatch the necessary emergency services.

SRS airbag precautions

Observe the following precautions. Failure to do so may result in death or serious injury.

●

The driver and all passengers must wear their seat belts correctly.
The SRS airbags are supplemental devices to be used with the seat belts.

●

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 the driver’s airbag is the first 2 - 3 in. (50 - 75 mm) of inflation,
placing yourself 10 in. (250 mm) from your driver airbag provides you with a clear

6-3. Reducing impact to the occupants in a collision

WARNING

margin of safety. This distance is measured from the center of the steering wheel to
your breastbone. If your current driving position places you less than 10 in. (250 mm)
away from the driver airbag, you can change your driving position in several ways:

•

Move your seat to the rear as far as possible while still being able to reach the
pedals comfortably.

•

Slightly recline the seatback. Although vehicle designs vary, many drivers can
achieve the 10 in. (251 mm) distance, even with the driver seat all the way forward,
simply by reclining the seatback somewhat. If reclining the seatback 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 recom-
mended by the NHTSA, while still being able to control the vehicle with the pedals
and steering wheel, and maintaining your view of the instrument panel controls.

●

If a seat belt extender has been connected to a
front seat belt buckle but the latch plate of the
seat belt has not been fastened to the seat belt
extender, the SRS airbag system will judge that
the occupant is wearing the seat belt even though
the seat belt has not been fastened. In this case,
the SRS front airbags may not deploy correctly in
a collision, resulting in death or serious injury. Be
sure to wear the seat belt correctly when using a
seat belt extender.

●

The SRS front passenger airbag 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 positioned as far possible from the airbag with the seatback
adjusted so that the passenger is sat upright.

●

Improperly seated and/or restrained infants and children can be killed or seriously
injured by a deploying airbag. 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 seats of the vehicle and properly
restrained. The rear seats are safer for infants and children than the front passenger
seat.

WARNING

●

Do not sit on the edge of the seat or lean against
the dashboard.

●

Do not allow a child to stand in front of the SRS
front passenger airbag or sit on the lap of a front
passenger.

●

Front seat occupants should never hold items on
their lap.

●

Do not lean against the door, roof side rail, or front,
side, or rear pillar.

●

Do not allow anyone to kneel on a seat toward
the door or put their head or hands outside the
vehicle.

●

Do not attach anything to or lean anything against
areas such as the dashboard, steering wheel pad
and lower portion of the instrument panel.

WARNING

●

Do not attach anything to areas such as the doors,
windshield, side windows, front or rear pillars, roof
side rails and assist grips. (With the exception of
the speed limit label )

●

Do not hang coat hangers or other hard objects on the coat hooks. These items could
become projectiles if the SRS curtain shield airbags deploy, possibly leading to death
or serious injury.

●

If a vinyl cover is attached to the area where the SRS knee airbag deploys, be sure to
remove it.

●

Do not use seat accessories which cover the parts from which the SRS airbags deploy,
as they may interfere with inflation of the SRS airbags. Such accessories may prevent
the SRS airbags from deploying correctly, may disable the system or cause the SRS
airbags to inflate unintentionally, possibly resulting in death or serious injury.

●

Do not strike or apply significant force to the SRS airbag system components, front
doors or their surrounding area. Doing so may cause the SRS airbags to malfunction.

●

Do not touch any components of the SRS airbags immediately after the SRS airbags
have deployed (inflated) as they may be hot.

●

If breathing becomes difficult after the SRS airbags have deployed, open a door or
window to allow fresh air in, or leave the vehicle if it is safe to do so. Wash off any
residue as soon as possible to prevent skin irritation.

●

If a part where an SRS airbag is stored is damaged or cracked, have it replaced by
your Lexus dealer.

●

Do not place anything, such as a cushion, on the front passenger's seat. Doing so
will disperse the passenger’s weight, which prevents the sensor from detecting the
passenger’s weight properly. As a result, the SRS front airbags for the front passenger’s
seat may not deploy in the event of a collision.

Do not dispose of your vehicle or perform any of the following modifications without
consulting your Lexus dealer.
The SRS airbags may malfunction or deploy unintentionally, possibly leading to death or
serious injury.
