2154-1. Before driving
4
DrivingCargo capacity depends on the
total weight of the occupants.
(Cargo capacity) = (Total load
capacity) - (Total weight of occu-
pants)
Steps for Determining Correct
Load Limit 
(1) Locate the statement “The
combined weight of occupants
and cargo should never exceed
XXX kg or XXX lbs.” on your
vehicle’s placard.
(2) Determine the combined
weight of the driver and passen-
gers that will be riding in your
vehicle.
(3) Subtract the combined
weight of the driver and passen-
gers from XXX kg or XXX lbs.
(4) The resulting figure equals
the available amount of cargo
and luggage load capacity.
Cargo and luggage
Take notice of the following
information about storage
precautions, cargo capacity
and load.
WARNING
■Things that must not be car-
ried in the luggage compart-
ment
The following things may cause a
fire if loaded in the luggage com-
partment:
●Receptacles co ntaining gaso-
line
●Aerosol cans
■Storage precautions
Observe the following precau-
tions. Failure to do so may pre-
vent the pedals from being
depressed properly, may block
the driver’s vision, or may result in
items hitting the d river or passen-
gers, possibly causing an acci-
dent.
●Stow cargo and luggage in the
luggage compartment when-
ever possible.
●Do not stack anything in the lug-
gage compartment higher than
the seatbacks.
●Do not place cargo or luggage
in or on the following locations.
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• On the instrument panel
• On the dashboard
• On the auxiliary box or tray that has no lid
●Secure all items in the occupant
compartment.
●When you fold down the rear
seats, long items should not be
placed directly behind the front
seats.
●Never allow anyon e to ride in
the luggage compartment. It is
not designed for passengers.
They should ride in their seats
with their seat belts properly
fastened. Otherw ise, they are
much more likely to suffer death
or serious bodily injury, in the
event of sudden braking, sud-
den swerving or an accident.

f daily vehicle
checks.
■Tire inflation pressure
●It may take a few minutes to dis-
play the tire inflation pressure
after the power switch is turned to
ON. It may also take a few min-

passing through the tire
tread can be repaired tem-
porarily using the emer-
gency tire puncture repair
kit. (The kit contains a bottle
of sealant. The sealant can
be used only once to tempo-
rarily repair one tire without
removing the nail or screw
from the tire.) Depending on
the damage condition of the
flat tire, it may not be able to
repaired with the emer-
gency tire puncture repair
kit. ( P.482)
After temporarily repairing

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.H

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.
●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 gon-
flable. Pour assur er une marge
de sécurité 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 pou-
vez changer votre position 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-l e 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.
