Fuel cell electric ve hicle characteristics
Fuel cell electric vehicle efficiently use electricity, which i s
generated by a chemical reaction between hydrogen and oxy-
gen in a fuel cell stack, and electricity charged in a traction
battery to drive the electric motor (traction motor).
The fuel is H2 (compressed hydrogen gas), so the exhaust is
only water and water vapor. As they do not release emissions
such as CO
2 (Carbon Dioxide) and NOx (Nitrogen Oxides),
fuel cell electric vehicles are environmentally friendly vehi-
cles.

■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.

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.
