For safety and security
Your vehicle is equipped with ADVANCED AIRBAGS designed based on the
US motor vehicle safety standards (FMVSS208). The airbag sensor assembly
(ECU) controls airbag deployment based on information obtained from the sen-
sors etc. shown in the system compon ents diagram above. This information
includes crash severity and occupant information. As the airbags deploy, a
chemical reaction in the inflators quickly fills the airbags with non-toxic gas to
help restrain the moti on 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 device s to be used with the seat belts.
●The SRS driver airbag deploys with consider able force, and can cause death or seri-
ous injury especially if the driver is very close to the airbag. The National Highway
Traffic Safety Administration (NHTSA) advises:
Since the risk zone for the driver’s airbag is the 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 com- fortably.
• Slightly recline the back of the seat. Al though vehicle designs vary, many drivers
can achieve the 10 in. (250 mm) distance, even with the driver seat all the way for-
ward, simply by reclining the back of th e 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 ad justable, tilt it downward. This points the airbag toward
your chest instead of your head and neck.
The seat should be adjusted as recommen ded by NHTSA above, while still maintain-
ing control of the foot pedals, steering whee l, and your view of the instrument 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 airbag as possible with the seatback
adjusted, so the front passenger sits upright.
●Improperly seated and/or re strained 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 recom-
mends that all infants and children be placed in the rear seats of the vehicle and prop-
erly restrained. The rear seats are safe r for infants and children than the front
passenger seat. ( P. 5 2 )
●If the seat belt extender has been connected
to the front seat belt buckles but the seat belt
extender has not also been fastened to the
latch plate of the seat belt, the SRS front air-
bags will judge that the driver and front pas-
senger are wearing the seat belt even though
the seat belt has not been connected. In this
case, the SRS front airbags may not activate
correctly in a collision, resulting in death or
serious injury in the event of collision. Be sure
to wear the seat belt with the seat belt
extender.
●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.

CAUTION
■SRS airbag precautions
●Do not lean against the door, the roof side rail
or the front, side and rear pillars.
●Do not allow anyone to kneel on the passen-
ger 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, steering
wheel pad and lower portion of the instru-
ment panel.
These items can become projectiles when the
SRS driver, front passenger and knee airbags
deploy.

■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result fr om 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, parts of the front, side 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.
●For Safety Connect subscribers, if the SRS airbags deploy or in the event of a severe
rear-end collision, the system is designed to send an emergency call to the response
center, notifying them of the vehicle’s location (without needing to push the “SOS” but-
ton) and an agent will attempt to speak wi th the occupants to ascertain the level of
emergency and assistance required. If the oc cupants are unable to communicate, the
argent automatically treats the call as an emergency and helps to dispatch the neces-
sary emergency services. ( P. 4 2 8 )
CAUTION
■Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications without
consulting your Lexus dealer. The SRS airb ags may malfunction or deploy (inflate)
accidentally, causing de ath or serious injury.
●Installation, removal, disassembl y and repair of the SRS airbags
●Repairs, modifications, removal or replac ement of the steering wheel, instrument
panel, dashboard, seats, seat upholstery, fron t, 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 a grille guar d (bull bars, kangaroo bar, etc.), snow plows, winches or
roof luggage carrier
●Modifications to the vehicle’s suspension system
●Installation of electronic devices such as mobile two-way radios and CD players
●Modifications to your vehicle for a person with a physical disability

■Types of collisions that may not deploy the SRS airbags (SRS front airbags)
The SRS front airbags do not gene rally 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 forwar d deceleration of the vehicle, deployment of
the SRS front airbags may occur.
■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 pitches end over end, or if it is involved in a low-speed side collision.
●Collision from the side
●Collision from the rear
●Vehicle rollover
●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
●Pitching end over end
