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 fuel cell system will be
stopped and hydr ogen supply will
be stopped fro m the hydrogen
tank valves. ( P. 8 9 )
●All of the doors will be unlocked.
( P.128)
●The brakes and st op lights will be
controlled automatically. ( P.323)
●The interior lights will turn on auto-
matically. ( P.357)
●The emergency flashers will turn
on automatically. ( P.446)
●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. 6 5 )
• An SRS airbag is deployed.
• A seat belt pretensioner is acti- vated.
• The vehicle is involved in a severe rear-end collision.
■SRS airbag deployment condi-
tions (SRS front airbags)
●The SRS front airbags will deploy
in the event of an impact that
exceeds the set threshold level
(the level of forc e corresponding
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 follow-
ing situations:

822-1. Fuel cell electric vehicle

■High-voltage and high-temperature components
The fuel cell electric vehicle has high-voltage components (abo ut
650 V maximum) such as a fuel c ell stack, traction battery, power
control unit, fuel cell converter, high-voltage cables (which a re distin-
guished from low-voltage cables b y their orange covers), electric
motor (traction motor), etc., and high-temperature parts such a s the
radiator for cooling. Pay attention to all warning labels attached to
the vehicle.
This diagram is for illustrative purposes only and may differ f rom the actual
vehicle.

vehicle has been in an accident or
is malfunctioning
●On an extremely bumpy road, on
an incline, on gravel, or on grass
●When a tire chains, compact
spare tire or an emergency tire
puncture repair kit is used

Advanced Park)
Approximately 3.3 ft. (100

The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect objects that
are extremely clos

The range of the sensors may
change depending on the shape of
the object, etc.

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 déploiement 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 occupants. Au moment du déploiement
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.
AVERTISSEMENT
■Précautions relatives aux
coussins gonflables SRS
Observez les pré cautions suiva-
ntes en ce qui concerne les cous-
sins gonflables SRS.
Négliger de le faire pourrait occa-
sionner des blessures graves,
voire mortelles.
●Le conducteur et tous les pas-
sagers du véhicule doivent por-
ter leur ceinture de sécurité de
la manière appropriée.
Les coussins gonflables SRS
sont des disposit ifs supplémen-
taires qui doivent être utilisés
avec les ceintures de sécurité.
