GS350/250_EE (OM30C36E)The main SRS airbag system components are shown above. The
SRS airbag 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 ped-
als 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 above, while still maintain-
ing control of the foot pedals, steering wheel, and your view of the instru-
ment panel controls.

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 air-
bag as possible with the seatback adjusted, so the front passenger sits
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. (P.
59)
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 pil-
lars.

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 air-
bags 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
passenger seats toward the door or put
their head or hands outside the vehicle.
Do not attach anything to or lean any-
thing against areas such as the dash-
board, steering wheel pad, lower
portion of the instrument 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. 810)

CAUTION
SRS airbag precautions
Do not strike or apply significant levels of force to the area of the SRS air-
bag components.
Doing so can cause the SRS airbags to malfunction.
Do not touch any of the component parts immediately after the SRS air-
bags 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 the areas where the SRS airbags are stored, such as the steering wheel
pad, door of the glove box and front and rear pillar garnishes are damaged
or cracked, have them replaced by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifica-
tions without consulting any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional. The SRS airbags may malfunc-
tion or deploy (inflate) accidentally, causing death or serious injury.
Installation, removal, disassembly and repair of the SRS airbags
Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, glove box, seats or seat upholstery, front,
side and rear pillars or roof side rails
Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment
Installation of snow plows, winches, etc. to the front grille (bull bars or
kangaroo bar etc.)
Modifications to the vehicle’s suspension system
Installation of electronic devices such as an RF-transmitter and CD play-
ers
Modifications to your vehicle for a person with a physical disability

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 follow-
ing situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole,
which can move 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 pre-
tensioners 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.] vehi-
cle colliding with the vehicle cabin from a direction perpendicular 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 collision.

wise damaged.

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
deployment (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.
