Front impact sensors
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 components 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 no n-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 seat s, parts of the front
and rear pillars, and r oof side rails may be
hot for several minutes. The airbag itself
may also be hot.
●The windshield may crack.
●The interior lights will turn on automati-
cally. ( P.277)
●The emergency flashers will turn on auto-
matically. ( P.356)
●For Lexus Enform Safety Connect sub-
scribers, if any of the following situations
occur, 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” but-
ton) and an agent will attempt to speak
with the occupants to ascertain the level
of emergency and assi stance required. If
the occupants are unable to communi-
cate, the agent automatically treats the
call as an emergency and helps to dis-
patch the necessary emergency services. (
 P.54)
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear- end collision.
■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
considerably higher in the following situa-
tions:
• 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 th e seat belt preten-
sioners and SRS knee airbags will acti-
vate.
●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.
■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 thresh old 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 vehi cle orientation at an
approximate speed of 12 - 18 mph [20 -
30 km/h]).
●Both SRS curtain shield airbags may
deploy in the event of a severe side colli-
sion.
●Both SRS curtain shield airbags will
deploy in the event of vehicle rollover.
●Both SRS curtain shield airbags may also
deploy in the event of a severe frontal col-
lision.
■Conditions under which the SRS air-
bags may deploy (inf late), other than a
collision
The SRS front airbags and SRS curtain
shield 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
The SRS curtain shield airbags may also
deploy under the situations shown in the
illustration.
●The angle of vehicle tip-up is marginal.
●The vehicle skids and hits a curb stone.
■Types of collisions that may not deploy
the SRS airbags (SRS front airbags)
The SRS front airbags do not generally
inflate if the vehicle is involved in a side or
rear collision, if it rolls over, or if it is involved
in a low-speed frontal collision. But, when-
ever a collision of any type causes sufficient
forward deceleration of the vehicle, deploy-
ment of the SRS fron t airbags may occur.
●Collision from the side
●Collision from the rear
●Vehicle rollover
■Types of collisions that may not deploy
the SRS airbags (SRS side and curtain
shield airbags)
The SRS side and curtain shield airbags
may not activate if the vehicle is subjected
to a collision from the side at certain angles,
or a collision to the side of the vehicle body
other than the passenger compartment.
●Collision from the side to the vehicle
body other than the passenger compart-
ment
●Collision from the side at an angle

■Running out of fuel
When the vehicle has run out of fuel and the
hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to
make the low fuel level warning light
(  P.367) go off. If there is only a small
amount of fuel, the hybrid system may not
be able to start. (The standard amount of fuel is about 2.4gal. [9.0 L, 2.0 Imp.gal.],
when the vehicle is on a level surface. This
value may vary when the vehicle is on a
slope. Add extra fuel when the vehicle is
inclined.)
■Electromagnetic waves
●High voltage parts and cables on hybrid
vehicles incorporate electromagnetic
Hybrid system precautions
Take care when handling the hybrid system,
as it is a high voltage system (about
650 V at maximum) as well as contains parts that become extremely hot when
the hybrid system is operating. Obey th e warning labels attached to the vehi-
cle.
