The main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airbag sensor assembly. 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.
CAUTION
■SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts properly.
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.
Since the risk zone for the driver’s 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 pedalscomfortably.
• 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 above, while still maintaining con-
trol of the foot pedals, steering wheel, an d your view of the instrument panel con-
trols.

CAUTION
■SRS airbag precautions
●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.
●Improperly seated and/or restrained infants and children can be killed or seri-
ously 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. (→P. 5 9 )
●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 unit or sit on
the knees of a front passenger.
●Do not allow the front seat occupants to
hold items on their knees.
●Do not lean against the door, the roof side
rail or the front, side and rear pillars.

CAUTION
■SRS airbag precautions
●Do not hang coat hangers or hard objects on the coat hooks. All of these items
could become projectiles and may cause death or serious injury, should the SRS
curtain shield airbags deploy.
●If a vinyl cover is put on the area where the SRS knee airbag will deploy, be sure to
remove it.
●Do not use seat accessories which cover the parts where the SRS side airbags
inflate as they may interfere with inflation of the airbags. Such accessories 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.
●Do not allow anyone to kneel on the pas-
senger seats 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, steer-
ing wheel pad, lower portion of the instru-
ment panel and door of the glove box.
These items can become projectiles when
the SRS driver, front passenger and knee
airbags deploy.
●Do not attach anything to areas such as a
door, windshield glass, side door glass, front
or rear pillar, roof side rail and assist grip.
(Except for the speed limit label →P. 6 0 1 )

■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
●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 seats, the glove box, parts of the front and rear pillars, and roof side rails may be
hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.
■SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the set
threshold level (the level of force corresponding to an approximately 20 - 30 km/h
[12 - 18 mph] frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be considerably higher in the following situa-
tions:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which canmove or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the front of the vehicle “underrides”, or goes under, the bed of a truck
●Depending on the type of collision, it is possible that only the seat belt pretension-
ers will activate.
■SRS airbag deployment conditions (SRS side and curtain shield airbags)
●The SRS side and curtain shield airbags will deploy in the event of an impact that
exceeds the set threshold level (the level of force corresponding to the impact
force produced by an approximately 1500 kg [3300 lb.] vehicle colliding with the
vehicle cabin from a direction perpendi cular to the vehicle orientation at an
approximate speed of 20 - 30 km/h [12 - 18 mph]).
●The SRS curtain shield airbags may also deploy in the event of a severe frontal colli-
sion.

■Types of collisions that may not deploy the SRS airbags (SRS side and curtain shield
airbags)
The SRS side and curtain shield airbags may not activate if the vehicle is subjected to
a collision from the side at certain angles, or a collision to the side of the vehicle body
other than the passenger compartment.
The SRS side and curtain shield airbags do not generally inflate if the vehicle is
involved in a frontal or rear collision, if it rolls over, or if it is involved in a low-speed
side collision.
●Collision from the side to the vehicle body
other than the passenger compartment
●Collision from the side at an angle
●Collision from the front
●Collision from the rear
●Vehicle rollover

system. Have the vehicle inspected by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
●Neither “ON” nor “OFF” comes on.
●The indicator light does not change when the airbag manual on-off switch is
switched to “ON” or “OFF”.

CAUTION
■When installing a child restraint system
For safety reasons, always install a child restraint system in a rear seat. In the event
that the rear seat cannot be used, the front seat can be used as long as the airbag
manual on-off system is set to off.
If the airbag manual on-off system is left on, the strong impact of the airbag deploy-
ment (inflation) may cause serious injury or even death.
■When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off system is set to on.
If it is left off, the airbag may not deploy in the event of an accident, which may
result in serious injury or even death.

Child restraint systems
Studies have shown that installing a child restraint on a rear seat is much
safer than installing one on the front passenger seat.
●Choose a child restraint system that suits your vehicle and is appropri-
ate to the age and size of the child.
●For installation details, follow the instructions provided with the child
restraint system.
General installation instructions are provided in this manual. (→P. 7 0 )
●If child restraint system regulations exist in the country where you
reside, please contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional for the child restraint
system installation.
●Lexus recommends that you use a child restraint system which con-
forms to the regulation ECE No.44.
Lexus strongly urges the use of child restraint systems.
