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
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.

When to contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional
In the following cases, the vehicle will require inspection and/or repair. Con-
tact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional as soon as possible.
Any of the SRS airbags have been inflated.
The front of the vehicle is damaged or
deformed, or was involved in an acci-
dent that was not severe enough to cause
the SRS airbags to inflate.
A portion of a door is damaged or
deformed, or the vehicle was involved
in an accident that was not severe
enough to cause the SRS side and cur-
tain shield airbags to inflate.
The pad section of the steering wheel,
dashboard near the front passenger air-
bag, lower portion of the instrument
panel or door of the glove box is
scratched, cracked, or otherwise dam-
aged.

CAUTION
When adjusting the seat position
Take care when adjusting the seat position to ensure that other passengers
are not injured by the moving seat.
Do not put your hands under the seat or near the moving parts to avoid
injury.
Fingers or hands may become jammed in the seat mechanism.
Seat adjustment
To reduce the risk of sliding under the lap belt during a collision, do not
recline the seat more than necessary.
If the seat is too reclined, the lap belt may slide past the hips and apply
restraint forces directly to the abdomen, or your neck may contact the
shoulder belt, increasing the risk of death or serious injury in the event of
an accident.
Adjustments should not be made while driving as the seat may unexpect-
edly move and cause the driver to lose control of the vehicle.

Driving position memory
Check that the shift lever is in P.
Turn the engine switch to IGNITION ON mode.
Adjust the driver’s seat, steering wheel, and outside rear view
mirrors to the desired positions. (When memorizing the front
passenger’s seat, adjust the front passenger’s seat to the desired
positions.)
While pressing the “SET” but-
ton, or within 3 seconds after
the “SET” button is pressed,
press button “1”, “2” or “3”
until the signal beeps.
If the selected button has already
been preset, the previously
recorded position will be overwrit-
ten.
Your preferred driving position (the position of the driver’s seat,
steering wheel and outside rear view mirrors) can be memorized
and recalled by pressing a button. It is also possible to set this func-
tion to activate automatically when the doors are unlocked.
Three different driving positions can be entered into memory.
The same buttons are found on the front passenger’s side, allowing
the position of the front passenger’s seat to be memorized (if
equipped).
