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 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 fi rm, non-slippery cushion, or raise the
seat if your vehicle has that feature.
• If your steering wheel is adjustable, t ilt 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, and 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. 64)
●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
and seat cushion airbag inflate as they may interfere with inflation of the SRS air-
bags. Such accessories may prevent the side airbags and seat cushion airbag
from activating correctly, disable the system or cause the side airbags and seat
cushion airbag 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 and lower portion of the
instrument panel.
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
and rear pillar, roof side rail and assist grip.
(Except for the speed limit label P. 587)

CAUTION
■SRS airbag precautions
●Do not strike or apply significant levels of force to the area of the SRS airbag
components. Doing so can cause the SRS airbags to malfunction.
●Do not touch any of the component parts 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 the areas where the SRS airbags are stored, such as the steering wheel pad 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 perfor m any of the following modifications with-
out consulting any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional. The SRS airbags may malfunction 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, seats or seat upholstery, front, side and rear pillars or roof side
rails
●Repairs or modifications of the front fend er, front bumper, or side of the occupant
compartment
●Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows, winches
●Modifications to the vehicle’s suspension system
●Installation of electronic devices such as mobile two-way radios (RF-transmitter)
and CD players

■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may be sustained from SRS airbags, due to
the extremely high speed 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 seats, parts of the front and rear pillars, and roof side rails, may be hot for sev-
eral minutes. The airbag itself may also be hot.
●The windshield may crack.
■SRS airbag deployment conditions (SRS front airbags and SRS seat cushion air-
bag)
●The SRS front airbags and SRS seat cushion airbag 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 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 pretension-
ers will activate.
■SRS airbag deployment conditions (S RS 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 perpendicular to the vehicle orientation at an
approximate speed of 20 - 30 km/h [12 - 18 mph]).
●The SRS side and curtain shield airbags will deploy in the event of a severe frontal
collision.

■Conditions under which the SRS airbags may deploy (inflate), other than a collision
(SRS front airbags, SRS curtain shield airbag and SRS seat cushion airbag)
The SRS front airbags, SRS curtain shield airbag and SRS seat cushion airbag may
also deploy if a serious impact occurs to the underside of your vehicle. Some exam-
ples are shown in the illustration.
■Types of collisions that may not deploy the SRS airbags (SRS front airbags and SRS
seat cushion airbag)
The SRS front airbags and SRS seat cushion airbag do not generally inflate if the
vehicle is involved in a side or rear collision, if it rolls over, or if it is involved in a low-
speed frontal collision. But, whenever a collision of any type causes sufficient for-
ward deceleration of the vehicle, deployment of the SRS front airbags and SRS seat
cushion airbag may occur.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or falling
●Collision from the side
●Collision from the rear
●Vehicle rollover

LS600h/LS600hL_EE(OM50G20E)
■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 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.
The SRS curtain shield airbags do not generally inflate if the vehicle is involved in a
rear collision, if it rolls over, or if it is involved in a low-speed side or low-speed frontal
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
●Collision from the rear
●Vehicle rollover
