1-7. Safety information

Before driving
IS350/250_UIn 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.
■SRS warning light
This warning light system monitors the airbag sensor assembly, front airbag sensors,
side and curtain shield airbag sensor assemblies, curtain shield airbag sensor
assemblies, driver's seat position sensor, driver's seat belt buckle switch, seat belt
pretensioner assemblies, inflators, interconnecting wiring and power sources.
(
→ P. 4 7 2 )
■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, airbag cover and inflator) as well as
the front seats, and parts of the front pillar, rear pillar 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. 3 7 3 )

CAUTION
■SRS airbag precautions
●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.
●Do not strike or apply significant levels of force to the area of the SRS airbag
components shown on P. 94.
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 airbag has 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 pillar garnish, 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
SRS driver, front passenger and knee
airbags deploy.
●Do not attach anything to areas such as the
door, windshield glass, side door glass,
front and rear pillars, roof side rail or assist
grip.
●Do not hang coat hangers or other hard
objects on the coat hooks. All of these
items could become projectiles and seri-
ously injure or kill you, should the SRS cur-
tain shield airbag deploy.
