1-1. For safe use
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 sensors etc. shown in the system com-
ponents 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 motion of the occupants.
■ If the SRS airbags deploy (inflate)
Slight abrasions, burns, bruising, etc., may
●
be sustained from SRS airbags, due to the
extremely high speed deployment (infla-
tion) by hot gases.
● 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
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 Lexus Enform Safety Connect sub-
scribers, if the SRS airbags deploy or in
the event of a severe rear-end collision,
the system is designed to send an emer-
gency call to the response center, notify-
ing 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 emer-
gency 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.

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 corre-
sponding 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 con-
siderably higher in the following situations:
• If the vehicle strikes an object, such as a
parked vehicle or sign pole, which can
move 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 preten-
sioners will activate.
● The SRS front airbags for the front pas-
senger 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 unoccu-
pied. (→P.41)
The SRS seat cushion airbag on the front
●
passenger seat will not operate if the
occupant is not wearing a seat belt.
■ 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 per-
pendicular to the vehicle orientation at an
approximate speed of 12 -18 mph [20 -
30 km/h]).
The SRS curtain shield airbags will deploy
●
in the event of vehicle rollover.
● The SRS side and curtain shield airbags
may also deploy in the event of a severe
frontal collision.
Conditions under which the SRS air-
■
bags may deploy (inflate), other than a
collision
The SRS front airbags and SRS side and
curtain shield airbags may also deploy if a
serious impact occurs to the underside of
your vehicle. Some examples are shown in
the illustration.
