1-8. Safety information
HS250h_U_75050UThe main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airbag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and an airbag sensor.
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemical reaction in the inflators quickly
fills the airbags with non-toxic gas to help restrain the motion of the occu-
pants.
■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, 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 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. 4 0 8 )
■Operating 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 if the vehicle strikes
an object, such as a parked vehicle and 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.

■When to contact your Lexus dealer
In the following cases, contact your Lexus dealer as soon as possible.
●Any of the SRS airbags has been inflated.
●The front of the vehicle is damaged or
deformed, or was involved in an accident
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 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 front seats and rear seat
side garnishes (padding) with the side air-
bag is scratched, cracked, or otherwise
damaged.
●The portion of the front pillars, rear pillars
or roof side rail garnishes (padding) con-
taining the curtain shield airbags inside is
scratched, cracked, or otherwise dam-
aged.

CAUTION
■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
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.
●Do not allow anyone to kneel on the pas-
senger seats toward the door or put their
head or hands outside the vehicle.

CAUTION
■SRS airbag precautions
●If a vinyl cover is put on the area where the SRS knee airbags 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 and
front and rear pillar garnishes, are damaged or cracked, have them replaced by
your Lexus dealer.
●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 or rear pillar, 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 airbags deploy.
