For safety and security
US motor vehicle safety standards (FMVSS208). The airbag sensor assembly
(ECU) controls airbag deployment based on information obtained from the sen-
sors etc. shown in the system compon ents diagram above. This information
includes crash severity and occupant info rmation. As the airbags deploy, a chemi-
cal 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 may be hot for sev-
eral minutes. The airbag itself may also be
hot.
●The windshield may crack.
●All of the doors will be unlocked.
(  P.97)
●The brakes and stop lights will be con-
trolled automatically. ( P.219)
●The interior lights will turn on automati-
cally. ( P.244)
●The emergency flashers will turn on auto-
matically. ( P.306)
●Fuel supply to the engine will be stopped.
( P.313)
●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
considerably higher in the following situ-
ations:
• 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.
■SRS airbag deployment conditions (SRS
side airbags)
The SRS side airbags will deploy in the
event of an impact that exceeds the set
threshold level (the level of force corre-
sponding to the impact force produced by
an approximately 3300 lb. [1500 kg] vehi-
cle colliding with the vehicle cabin from a
direction perpendicular to the vehicle ori-
entation at an approximate speed of 12 - 18
mph [20 - 30 km/h]).

2084-5. 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 obstacles 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 and Center Display
Sensors that detect an obstacle will illu-
minate continuously or blink.NOTICE
●If a display error occurs, first check the
sensor.
If the error occurs even when there is
no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
■Notes when washing the vehicle
Do not apply intensive bursts of water or
steam to the sensor area.
Doing so may result in the sensor mal-
functioning.

3849-1. For owners
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.
AVERTISSEMENT
■Précautions relatives aux coussins
gonflables SRS
Observez les précautions suivantes en
ce qui concerne les coussins gonflables
SRS.
Les négliger pourrait occasionner des
blessures graves, voire mortelles.
●Le conducteur et tous les passagers
du véhicule doivent porter leur cein-
ture de sécurité de la manière appro-
priée.
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 déploiement du
coussin gonflable. Pour assurer une
marge de sécurité su ffisante, 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 pou-
vez changer votre position de con-
duite de plusieurs manières :
• Reculez votre siège à la position maxi- male vous permettant d’atteindre
encore aisément les pédales.
