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
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 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,
door of the glove box and front and rear pillar garnishes are damaged or cracked,
have them replaced by your Lexus dealer.
●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.

■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.
●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” button) and an agent will attempt to speak with the occupants to ascer-
tain the level of emergency and assistance required. If the occupants are unable to
communicate, the agent automatically treats the call as an emergency and helps to
dispatch the necessary emergency services. (→P. 6 0 7 )
CAUTION
■Modification and di sposal 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 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, glove box, 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 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 mobile two-way radios and CD players
●Modifications to your vehicle for a person with a physical disability

■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 12 - 18 mph
[20 - 30 km/h] 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 canmove 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.
●The SRS front airbags for the front passenger will not activate if there is no passen-
ger sitting in the front passenger seat. However, the SRS front airbags for the front
passenger may deploy if luggage is put in the seat, even if the seat is unoccupied.
(→ P. 4 9 )
■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 3300 lb. [1500 kg] vehicle colliding with the
vehicle cabin from a direction perpendicular to the vehicle orientation at an
approximate speed of 12 - 18 mph [20 - 30 km/h]).
●The SRS curtain shield airbags may also deploy in the event of a severe frontal colli-
sion.
■Conditions under which the SRS airbags may deploy (inflate), other than a collision
The SRS front airbags may also deploy if a serious impact occurs to the underside of
your vehicle. Some examples are shown in the illustration.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or falling

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 curtain shield air-
bags to inflate.
●The pad section of the steering wheel, dash-
board near the front passenger airbag,
lower portion of the instrument panel or
door of the glove box is scratched, cracked,
or otherwise damaged.
●The surface of the seats with the side airbag
is scratched, cracked, or otherwise dam-
aged.

roof side rail garnishes (padding) containing
the curtain shield airbags inside is scratched,
cracked, or otherwise damaged.

*1: The system judges a person of adult size as an adult. When a smaller adult sitsin 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 outgrown a child restraint system sits in the frontpassenger seat, the system may recognize him/her as an adult depending on
his/her physique or posture.
*4: Never install a rear-facing child restraint system on the front passenger seat. A
forward-facing child restraint system should only be installed on the front pas-
senger seat when it is unavoidable. ( →P. 5 5 )
*5: In case the indicator light is not illuminated, consult this manual on how to
install the child restraint system properly. ( →P. 5 9 )
CAUTION
■Front passenger occupant classification system precautions
Observe the following precautions regarding the front passenger occupant classi-
fication system.
Failure to do so may cause death or serious injury.
●Wear the seat belt properly.
●Make sure the front passenger’s seat belt plate has not been left inserted into the
buckle before someone sits in the front passenger seat.
●Make sure the “AIR BAG OFF” indicator light is not illuminated when using the
seat belt extender for the front passenger seat. If the “AIR BAG OFF” indicator
light is illuminated, disconnect the extender tongue from the seat belt buckle, and
reconnect the seat belt. Reconnect the seat belt extender after making sure the
“AIR BAG ON” indicator light is illuminated. If you use the seat belt extender
while the “AIR BAG OFF” indicator light is illuminated, the SRS airbags for the
passenger may not activate correctly, which could cause death or serious injury
in the event of a collision.
●Do not apply a heavy load to the front passenger seat or equipment (e.g. seat-
back pockets or armrest).
●Do not put weight on the front passenger seat by putting your hands or feet on
the front passenger seat seatback from the rear passenger seat.
●Do not let a rear 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.
