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.270)
●The emergency flashers will turn on auto-
matically. ( P.344)
●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. (

• 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

●If objects draw too close to the sensor.
■Objects which may not be properly
detected
The shape of the object may prevent the
sensor from detecting it. Pay particular
attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that
absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections project-
ing outwards in the direction of your vehi-
cle
People may not be detected if they are
wearing certain types of clothing.
■Detection range of the sensors
Approximately 3.3 ft. (100 cm)
Approximately 4.9 ft. (150 cm)
Approximately 2.0 ft. (60 cm)
The diagram shows the detection range of
the sensors. Note that the sensors cannot
detect objects that are extremely close to
the vehicle.
The range of the sensors may change
depending on the shape of the object, etc.
■Multi-information display, head-up display (if equipped) and Center Display
When an object is detected by a sensor, the approximate distance to the object will
be displayed on the multi-information displa y, Center Display, and head-up display.
(As the distance to the object becomes sh ort, the distance segments may blink.)
Approximate distance to object: 4. 9 ft. (150 cm) to 2.0 ft. (60 cm)

Votre véhicule est doté de COUSSINS GONFLABLES ÉVOLUÉS dont la con-
ception s’appuie sur les normes de sécurité des véhicules à moteur américains
(FMVSS208). Le module de capteur de coussin gonflable (ECU) contrôle le
déploiement des coussins gonflables en fonction des informations obtenues des
capteurs et d’autres éléments affichés dans le diagramme des\
composants du sys-
tème ci-dessus. Ces informations compre nnent des données relatives à la gravité
de l’accident et aux occupants. Au moment du déploiement des coussins gonfla-
bles, une réaction chimique se produit dans les gonfleurs de coussin gonflable et
les coussins gonflables se remplissent rapidement d’un gaz non toxique pour aider
à limiter le mouvement des occupants.N

AVERTISSEMENT
■Précautions relatives aux coussins
gonflables SRS
Observez les précautions suivantes en
ce qui concerne les coussins gonflables
SRS.
Négliger de le faire pourrait occasionner
des blessures graves, voire mortelles.
●Le conducteur et tous les passagers du
véhicule doivent porter leur ceinture
de sécurité de la manière appropriée.
Les coussins gonflables SRS sont des
dispositifs supplémentaires qui doivent
être utilisés avec les ceintures de sécu-
rité.
