Front passenger occupant classification sensors
Driver’s knee airbag
SRS warning light
Airbag sensor assembly
Your vehicle is equipped with ADVANCED AIRBAGS designed
based on the US motor vehicle safety standards (FMVSS208). The
airbag sensor assembly (ECU) cont rols airbag deployment based on
information obtained from the sensors etc. shown in the system
components diagram above. This in formation includes crash sever-
ity 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 (inflation) by
hot gases.
●A loud noise and white powder will
be emitted.
●Parts of the airbag module (steer-
ing 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. T he 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.86)
●All of the doors will be unlocked.
( P.134)
●The brakes and st op lights will be
controlled automatically. (
 P.336)
●The interior lights will turn on auto-
matically. ( P.365)
●The emergency flashers will turn
on automatically. ( P.456)
●For Safety Connect subscribers, 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” button)
and an agent will attempt to speak
with the occupants to ascertain
the level of emergency and assis-
tance required. If the occupants
are unable to communicate, the
agent automatically treats the call
as an emergency and helps to dis-
patch the necessary emergency
services. ( P.75)
• An SRS airbag is deployed.
• A seat belt pretensioner is acti- vated.
• The vehicle is involved in a severe rear-end collision.

Driving
●When vehicle horns, vehicle
detectors, motorcycle engines, air
brakes of large vehicles, the clear-
ance sonar of other vehicles or
other devices which produce ultra-
sonic waves are near the vehicle.
●If the front of the vehicle is raised
or lowered due to the carried load.
●If the orientation of a sensor has
been changed due to a collision or
other impact.
●The vehicle is approaching a tall
or curved curb.
●Driving close to columns (H-
shaped steel beams, etc.) in multi-
story parking garages, construc-
tion sites, etc.
●If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or
is malfunctioning.
●On an extremely bumpy road, on
an incline, on gravel, or on grass.
●When tire chains, a compact
spare tire or an emergency tire
puncture repair kit are used.
■Detection range of the sen-
sors
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 clos e to the vehicle.
The range of the sensors may
change depending on the shape of
the object, etc.
■Distance display
When an object is detected by a
sensor, the approximate dis-
tance to the object will be dis-
played on the multi-information
display and audio system
screen. (As the distance to the
object becomes short, the dis-
tance segments may blink.)

Module de capteur de coussin gonflable
Votre véhicule est doté de COUSSINS GONFLABLES ÉVOLUÉS
dont la conception s’appuie sur les normes de sécurité des véhi cules
à moteur américains (FMVSS208). Le module de capteur de coussin
gonflable (ECU) contrôle le déplo iement des coussins gonflables en
fonction des informations obtenues des capteurs et d’autres élé-
ments affichés dans le diagramme des composants du système ci-
dessus. Ces informations comprennent des données relatives à la
gravité de l’accident et aux occ upants. Au moment du déploiemen t
des coussins gonflables, une réaction chimique se produit dans les
gonfleurs de coussin gonflable et les coussins gonflables se remplis-
sent rapidement d’un gaz non toxique pour aider à limiter le mo uve-
ment des occupants.G
