Fuel cell vehicle characteristics
Fuel cell vehicles efficiently use electricity, which is gener-
ated by a chemical reaction between hydrogen and oxygen in
a fuel cell stack, and electricity charged in a traction batter y
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 vehicles are environmentally friendly vehicles.
Fuel cell vehicle components

■High-voltage and high-temperature components
The fuel cell vehicle has high-voltage components (about 650 V
maximum) such as a fuel cell stack, traction battery, power con trol
unit, fuel cell converter, high-voltage cables (which are distinguished
from low-voltage cables by their orange covers), electric motor (trac-
tion motor), etc., and high-temperature parts such as the radiator for
cooling. Pay attention to all w arning labels attached to the 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.

For owners
AVERTISSEMENT
●Le coussin gonflable SRS du
conducteur se déploie avec une
force considérable et peut occa-
sionner des blessures graves,
voire mortelles, notamment lor-
sque le conducteur se trouve
très près du coussin gonflable.
La National Highway Traffic
Safety Administration (NHTSA),
aux États-Unis, fait les recom-
mandations 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 sécu-
rité suffisante, restez à 10 in.
(250 mm) du coussin gonflable.
Cette distance est mesurée du
centre du volant à votre sternum.
Si maintenant vous vous tenez
assis à moins de 10 in. (250 mm),
vous pouvez changer votre posi-
tion de conduite de plusieurs
manières :
• Reculez votre siège à la posi- tion maximale vous permettant
d’atteindre encore aisément les
pédales.
• Inclinez légèrement le dossier du siège.
Bien que les véhicules soient
conçus différemment, la plupart
des conducteurs peuvent main-
tenir une distance de 10 in.
(250 mm), même si leur siège
se trouve complètement vers
l’avant, simplement en inclinant
un peu le dossier du siège vers
l’arrière. Si la visibilité avant est
moindre après avoir incliné le
dossier de votre siège, utilisez
un coussin ferme et non glissant
pour être assis plus haut ou
relevez le siège s i cette option
est disponible sur votre
véhicule.
• Si votre volant est réglable en hauteur, inclinez-le vers le bas.
Cela vous permet d’orienter le
coussin gonflable vers votre
buste plutôt que v ers votre tête
et vers votre cou.
Le siège doit être réglé de la
manière recommandée ci-dessus
par la NHTSA, tout en gardant le
contrôle des pédales et du volant,
ainsi que la vue sur les com-
mandes du tableau de bord.
