■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 front seats, parts of the front, center and rear pillars and roof side rail,
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 ascertain the level of emergency and assistance required. If the occupants
are unable to communicate, the agent automatically treats the call as an emer-
gency and helps to dispatch the necessary emergency services. (→P. 5 8 0 )
■SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbag 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 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 threshold level, the SRS front airbags and the
seat belt pretensioners may not activate together.
●The SRS front airbags for the front passenger will not activate if there is no pas-
senger 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 unoc-
cupied. ( →P. 1 3 9 )

accident that was not severe enough to
cause the SRS side airbags and curtain
shield airbags to inflate.
●The pad section of the steering wheel,
dashboard near the front passenger airbag
or lower portion of the instrument panel is
scratched, cracked, or otherwise dam-
aged.
●The surface of the seats with the side air-
bag is scratched, cracked, or otherwise

■SRS airbag precautions
●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

CAUTION
■SRS airbag precautions
●Do not allow anyone to kneel on the pas-
senger seat 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 the
door, windshield glass, side door glass,
front, center or rear pillars, roof side rail
and assist grip.
●Do not hang coat hangers or other 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 airbag deploy.

■Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform 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 replacement of the steering wheel, instrument
panel, dashboard, seats or seat upholstery, front, center and rear pillars or roof
side rail
●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.)

CAUTION
■Child restraint precautions
●A forward-facing child restraint system may be installed on the front passenger
seat only when it is unavoidable. A child restraint system that requires a top tether
strap should not be used in the front passenger seat since there is no top tether
strap anchor for the front passenger seat. Adjust the seatback as upright as possi-
ble and always move the seat as far back as possible even if the “AIR BAG OFF”
indicator light is illuminated, because the front passenger airbag could inflate with
considerable speed and force. Otherwise, the child may be killed or seriously
injured.
●Do not use the seat belt extender when installing a child restraint system on the
front or rear passenger seat. If installing a child restraint system with the seat belt
extender connected to the seat belt, the seat belt will not securely hold the child
restraint system, which could cause death or serious injury to the child or other
passengers in the event of collision.
●Do not allow the child to lean his/her head or any part of his/her body against the
door or the area of the seat, front, center and rear pillars or roof side rail from
which the SRS side airbags or SRS curtain shield airbags deploy even if the child
is seated in the child restraint system. It is dangerous if the SRS side airbags and
curtain shield airbags inflate, and the impact could cause death or serious injury
to the child.
●Make sure you have complied with all installation instructions provided by the
child restraint manufacturer and that the system is properly secured. If it is not
secured properly, it may cause death or serious injury to the child in the event of a
sudden stop or accident.

■Conditions which may affect the rear view monitor system
●If the back of the vehicle has been hit, the camera’s position and mounting angle
may have changed. Have the vehicle inspected by your Lexus dealer.
●As the camera has a water proof construction, do not detach, disassemble or
modify it. This may cause incorrect operation.
●Rapid temperature changes, such as when hot water is poured on the vehicle in
cold weather, may cause the system to function abnormally.
●If the camera lens is dirty, it cannot transmit a clear image. Rinse with water and
wipe with a soft cloth. If the camera lens is extremely dirty, wash with a mild
cleanser and rinse.
●Do not strongly rub the camera lens. If the camera lens is scratched, it cannot
transmit a clear image.
●Do not allow organic solvent, car wax, window cleaner or glass coat to adhere to
the camera. If this happens, wipe it off as soon as possible.
●The displayed image may be darker and moving images may be slightly distorted
when the system is cold.
●Situations unsuitable for rear view monitor
• On icy or slick road surfaces, or in snow.
• When using tire chains or emergency tires.
• On roads that are not flat or straight, such as curves or slopes.
●When traveling on a sloping road, the area displayed on the screen may change.
●If the tires are changed, the area displayed on the screen may change.
●When washing the vehicle, do not apply intensive bursts of water to the camera
or camera area. Doing so may result in the camera malfunctioning.
