Before driving
Airbag system componentsYour vehicle is equipped with AD VANCED AIRBAGS designed based
on US motor vehicle sa fety standards (FMVSS208). The airbag system
controls airbag deployment power for the driver and front passenger. The
driver airbag system consists of the driver seat’s position sensor etc. The
front passenger’s airbag system con sists of the front passenger occupant
classification sensor etc.
The main SRS airbag system componen ts are shown above. The SRS air-
bag system is controlled by the airb ag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and an airbag sensor.

1-7. Safety information
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemica l reaction in the inflators quickly
fills the airbags with non-toxic gas to he lp restrain the motion of the occu-
pants.
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasion s 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 front seats, and parts of the front pillar and roof side rail, may be hot
for several minutes. The airbag itself may also be hot.
●The windshield may crack.
■Operating conditions (front airbags)
●The SRS front airbags will deploy if the severity of the frontal impact is above the
designed threshold level, comparable to an approximate 15 mph (25 km/h) col-
lision when the vehicle impacts straight into a fixed barrier that does not move
or deform.
However, this threshold velocity will be considerably higher if the vehicle strikes
an object, such as a parked vehicle or sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).
●It is possible that in some collisions where the forward deceleration of the vehi-
cle is very close to the designed thresh old level, the SRS front airbags and the
seat belt pretensioners ma y not activate together.
●The SRS front passenger airbag will not activate if there is not passenger sitting
in the front passenger seat. However, the front passenger airbag may deploy if
luggage is put in the seat or the seat belt is fastened, even if the seat is unoccu-
pied.

CAUTION
■SRS airbag precautions
Observe the following precautions regarding the 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. The National
Highway Traffic Safety Administration (“NHTSA”) advises:
Since the risk zone for driver airbag is th e first 2 - 3 in. (50 - 75 mm) of inflation,
placing yourself 10 in. (250 mm) 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 10 in. (250 mm) 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. Al though vehicle designs vary, many driv-
ers can achieve the 10 in. (250 mm) 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, ti lt it downward. This points the airbag
toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, while still main-
taining control of the foot pedals, steering wheel, and your view of the instrument
panel controls.

CAUTION
■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 your Lexus dealer. The SRS airbag may malfunction or deploy
(inflate) accidentally, causing death or serious injury.
●Installation, removal, disassembly and repair of the SRS airbags
●Repairs, modifications, removal or replace ment of the steering wheel, instrument
panel, dashboard, seats or seat upholstery, front, side and rear pillars or roof side
rail
●Repairs or modifications of the front fend er, front bumper, or side of the occupant
compartment
●Installation of snow plows, winches, etc. to the front grille (bull bars, kangaroo bar
etc.)
●Modifications to the vehi cle's suspension system
●Installation of electronic devices such as mobile two-way radios or CD players
●Modifications to your vehicle for a person with a physical disability.

1-7. Safety information
■This switch only should be used
In a situation where the inflation is not desired (such as during extreme off road driv-
ing).
■Operating conditions when the RSCA OFF indicator turns on
●The curtain shield airbag and seat belt pretensioner will not activate in a vehicle
rollover.
●The curtain shield airbag will activate in a severe side impact.
CAUTION
■While normal driving
Make sure the RSCA OFF indicator light is not turned on. If it is left on, the curtain
shield airbag will not activate in the event of an accident, which may cause death or
serious injury.

Before driving
■There is a malfunction in the system
*1: The system judges a person of adul t size as an adult. When a smaller
adult sits in the front passenger seat, the system may recognize him/
her as a child depending on his/her physique and posture.
*2: In the event the front passenger does not wear a seat belt.
*3: When a larger child who has outgr own a child restraint system sits in
the front passenger seat, the system may recognize him/her as an
adult depending on his/her physique or posture.
*4: Never install a real-facing child restraint system on the front passen- ger seat. A forward-facing child restraint system should only be
installed on the front passenger seat when it is unavoidable.
( P. 7 2 )
*5: In case indicator is not illuminated , consult this manual as for installing
the child restraint system properly. ( P. 7 5 )

■Front passenger occupant classification system precautions
Observe the following precautions regardin g front passenger occupant classifica-
tion system.
Failure to do so may cause death or serious injury.
●Wear the seat belt properly.
●Make sure the front passenger’s seat belt tab has not been left inserted into the
buckle before someone sits in the front passenger seat.
●Make sure the AIRBAG OFF indicator light is not illuminated when using the seat
belt extender for the front passenger se at. If the AIRBAG OFF indicator light is
illuminated, disconnect the extender tongue from the seat belt buckle, then
reconnect the seat belt. Reconnect the seat belt extender after making sure the
AIRBAG ON indicator light is illuminated. If you use the seat belt extender while
the AIRBAG OFF indicator li ght is illuminated, the front passenger airbag and
side airbag on the front passenger side may not activate correctly, which could
cause death or serious injury in the event of collision.
●Do not apply a heavy load to the front passenger seat.
●Do not put weight on the front passenger seat by putting your hands or feet on
the front passenger seat seatback fr om the second seat passenger seat.
●Do not let a second seat passenger lift the front passenger seat with their feet or
press on the seatback with their legs.
●Do not put objects under the front passenger seat.
●Do not recline the front passenger seatback so far that it touches a second seat.
This may cause the AIRBAG OFF indicator light to be illuminated, which indi-
cates that the passenger’s airbags will not deploy in the event of a severe acci-
dent. If the seatback touche s the second seat, return the seatback to a position
where it does not touch the second seat. Keep the front passenger seatback as
upright as possible when the vehicle is moving. Reclining the seatback exces-
sively may lessen the effectiveness of the seat belt system.
