Rear side airbags
Side impact sensors (front door)
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 roof side rails, may
be hot for several minutes. The airbag
itself may also be hot.
●The windshield may crack.
●The hybrid system will be stopped and
fuel supply to the engine will be stopped.
(  P.68)
●All of the doors will be unlocked.
( P.109)
●The brakes and stop lights will be con-
trolled automatically. ( P.257)
●The interior lights will turn on automati-
cally. ( P.291)
●The emergency flashers will turn on auto-
matically. ( P.378)
●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.56)
• 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 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.

2364-5. Using the driving support systems
■Detection range of the sensorsApproximately 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
(vehicles with 10.3-inch display model)
When an object is detected by a sensor, the approximate distance to the object will
be displayed on the multi-information disp lay, Center Display (vehicles with 10.3-
inch display model), and head-up display (if equipped). (As the distance to the
object becomes short, the distance segments may blink.)
 Approximate distance to object: 4. 9 ft. (150 cm) to 2.0 ft. (60 cm)
* (Rear center
sensor)
*: Automatic buzzer mute function is enabled. ( P.238)

4529-1. For owners
Module de capteur de coussin gonflable
Coussins gonflables latéraux arrière
Capteurs d’impact latéral (portière avant)
Votre véhicule est doté de COUSSINS GONFLABLES ÉVOLUÉS dont la conception
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 gon-
flables en fonction des informations obtenues des capteurs et d’autres éléments affichés
dans le diagramme des composants du systèm e ci-dessus. Ces informations comprennent
des données relatives à la grav ité de l’accident et aux occupants. Au moment du déploie-
ment des coussins gonflables, une réaction chimique se produi t dans les gonfleurs de cous-
sin gonflable et les coussins gonflables se remplissent rapidement d’un gaz non toxique
pour aider à limiter le mouvement des occupants.

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.
●Le coussin gonflable SRS du conduc-
teur se déploie avec une force con-
sidérable et peut occasionner des
blessures graves, voire mortelles,
notamment lorsque le conducteur se
trouve très près du coussin gonflable.
La National Highway Traffic Safety
Administration (NHTSA), aux États-
Unis, fait les recommandations
suivantes :
La zone à risque du coussin gonflable
du conducteur couvre 2 à 3 in.
(50 à 75 mm) de la zone de déploie-
ment du coussin gonflable. Pour
assurer une marge de sécurité suff-
isante, restez à 10 in. (250 mm) du
coussin gonflable. Cette distance est
mesurée depuis le centre du volant
jusqu’à votre sternum. Si maintenant
vous vous tenez assis à moins de 10 in.
(250 mm), vous pouvez changer votre
position de conduite de plusieurs
manières :
• Reculez votre siège à la position maxi- male vous permettant d’atteindre
encore aisément les pédales.
