Fuel information

■

Gasoline quality

In very few cases, driveability problems may be caused by the brand of gaso-
line you are using. If driveability problems persist, try changing the brand of
gasoline. If this does not correct the problem, consult your Toyota dealer.

■

Recommendation of the use of gasoline containing detergent additives

●

Toyota recommends the use of gasoline that contains detergent additives to
avoid build-up of engine deposits.

●

All gasoline sold in the U.S.A. contains minimum detergent additives to
clean and/or keep clean intake systems, EPA’s lowest additives concentra-
tion program.

●

Toyota strongly recommends the use of Top Tier Detergent Gasoline. For
more information on Top Tier Detergent Gasoline and a list of marketers,
please go to the official website www.toptiergas.com.

You must only use unleaded gasoline in your vehicle.
Select octane rating 87 (Research Octane Number 91) or higher.
Use of unleaded gasoline with an octane rating lower than 87
may result in engine knocking. Persistent knocking can lead to
engine damage.

At minimum, the gasoline you use should meet the specifications of
ASTM D4814 in the U.S.A..

■

Recommendation of the use of low emissions gasoline

Gasolines containing oxygenates such as ethers and ethanol, as well as
reformulated gasolines, are available in some cities. These fuels are typically
acceptable for use, providing they meet other fuel requirements.
Toyota recommends these fuels, since the formulations allow for reduced
vehicle emissions.

■

Non-recommendation of the use of blended gasoline

●

If you use gasohol in your vehicle, be sure that it has an octane rating no
lower than 87.

●

Toyota does not recommend the use of gasoline containing methanol.

■

Non-recommendation of the use of gasoline containing MMT

Some gasoline contains an octane enhancing additive called MMT
(Methylcyclopentadienyl Manganese Tricarbonyl).
Toyota does not recommend the use of gasoline that contains MMT. If fuel
containing MMT is used, your emission control system may be adversely
affected.
The malfunction indicator lamp on the instrument panel may come on. If this
happens, contact your Toyota dealer for service.

■

If your engine knocks

●

Consult your Toyota dealer.

●

You may occasionally notice light knocking for a short time while accelerat-
ing or driving uphill. This is normal and there is no need for concern.

●

Use only gasoline containing up to 15%
ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 15% etha-
nol, including from any pump labeled
E30, E50, E85 (which are only some
examples of fuel containing more than
15% ethanol).

DO NOT use gaso-
line containing more
than 15% ethanol.

(30% ethanol)

(50% ethanol)

(85% ethanol)

NOTICE

■

Notice on fuel quality

●

Do not use improper fuels. If improper fuels are used, the engine will be
damaged.

●

Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s catalytic converters
causing the emission control system to malfunction.

●

Do not use gasohol other than that stated here.
Other gasohol may cause fuel system damage or vehicle performance
problems.

●

Using unleaded gasoline with an octane number or rating lower than the
level previously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.

■

Fuel-related poor driveability

If poor driveability (poor hot starting, vaporization, engine knocking, etc.) is
encountered after using a different type of fuel, discontinue the use of that
type of fuel.

■

When refueling with gasohol

Take care not to spill gasohol. It can damage your vehicle’s paint.

8-1. Specifications

■

Treadwear

The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a speci-
fied government test course.

For example, a tire graded 150 would wear one and a half (1-1/2)

times as well on the government course as a tire graded 100.

The relative performance of tires depends upon the actual condi-

tions of their use. Performance may differ significantly from the norm

due to variations in driving habits, service practices and differences

in road characteristics and climate.

■

Traction AA, A, B, C

The traction grades, from highest to lowest, are AA, A, B and C,
and they represent the tire’s ability to stop on wet pavement as
measured under controlled conditions on specified government test
surfaces of asphalt and concrete.

A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking

(straight ahead) traction tests and does not include cornering (turn-

ing) traction.

■

Temperature A, B, C

The temperature grades are A (the highest), B, and C, representing
the tire’s resistance to the generation of heat and its ability to dissi-
pate heat when tested under controlled conditions on a specified
indoor laboratory test wheel.

Sustained high temperature can cause the material of the tire to

degenerate and reduce tire life, and excessive temperature can lead

to sudden tire failure.
Grade C corresponds to a level of performance which all passenger

car tires must meet under the Federal Motor Vehicle Safety

Standard No. 109.
Grades B and A represent higher levels of performance on the labo-

ratory test wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is properly

inflated and not overloaded.

Excessive speed, underinflation, or excessive loading, either sepa-

rately or in combination, can cause heat buildup and possible tire

failure.

Votre véhicule est doté de COUSSINS GONFLABLES ÉVOLUÉS
dont la conception s’appuie sur les normes de sécurité des véhicules
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 éléments
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 remplissent rapide-
ment d’un gaz non toxique pour aider à limiter le mouvement des
occupants.

Précautions relatives aux coussins gonflables SRS

Observez les précautions suivantes en ce qui concerne les coussins gon-
flables SRS.
Les négliger pourrait occasionner des blessures graves, voire mortelles.

●

Le conducteur et tous les passagers du véhicule doivent porter leur cein-
ture de sécurité de la manière appropriée.
Les coussins gonflables SRS sont des dispositifs supplémentaires qui
doivent être utilisés avec les ceintures de sécurité.

●

Le coussin gonflable SRS du conducteur se déploie avec une force consi-
dérable et peut occasionner des blessures graves, voire mortelles, notam-
ment lorsque le conducteur se trouve très près du coussin gonflable. La
National Highway Traffic Safety Administration (NHTSA), aux États-Unis,
fait les recommandations 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 sécurité suffisante, restez à 10 in. (250 mm) du coussin
gonflable. Cette distance est mesurée depuis le centre du volant jusqu’à
votre sternum. Si maintenant vous vous tenez assis à moins de 10 in.
(250 mm), vous pouvez changer votre position de conduite de plusieurs
manières :
• Reculez votre siège à la position maximale vous permettant d’atteindre

encore aisément les pédales.

• Inclinez légèrement le dossier du siège.

Même si les véhicules sont conçus différemment, la plupart des
conducteurs peuvent maintenir une distance de 10 in. (250 mm), même
si leur siège se trouve complètement vers l’avant, simplement en incli-
nant 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 si
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
vers 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 commandes du tableau de bord.

560

SIENNA_OM_OM08035U_(U)

AVERTISSEMENT

■

Précautions relatives aux coussins gonflables SRS

●

Le coussin gonflable SRS du passager avant se déploie également avec
une force considérable et peut occasionner des blessures graves, voire
mortelles, notamment lorsque le passager avant se trouve très près du
coussin gonflable. Le siège du passager avant doit se trouver le plus loin
possible du coussin gonflable et le dossier doit être réglé de manière à ce
que le passager avant soit assis bien droit.

●

Le déploiement d’un coussin gonflable risque d’infliger des blessures
graves, voire mortelles, aux bébés et aux enfants mal assis et/ou mal atta-
chés. Un bébé ou un enfant trop petit pour utiliser une ceinture de sécurité
doit être correctement retenu à l’aide d’un dispositif de retenue pour
enfants. Toyota recommande vivement de placer et d’attacher correcte-
ment tous les bébés et tous les enfants sur les sièges arrière du véhicule à
l’aide de dispositifs de retenue adaptés. Les sièges arrière sont plus sécu-
ritaires pour les bébés et les enfants que le siège du passager avant.

●

N’installez jamais un dispositif de retenue pour enfants de type dos à la
route sur le siège du passager avant, même si le voyant “AIR BAG OFF”
est allumé. En cas d’accident, la force et la vitesse de déploiement du
coussin gonflable du passager avant pourraient infliger à l’enfant des bles-
sures graves, voire mortelles, si le dispositif de retenue pour enfants de
type dos à la route était installé sur le siège du passager avant.

●

Si la rallonge de ceinture de sécurité a
été reliée à la boucle des ceintures de
sécurité des sièges avant sans avoir
aussi été attachée à la plaque de blo-
cage des ceintures de sécurité, les
coussins gonflables SRS avant consi-
déreront que le conducteur et le passa-
ger avant portent tout de même leur
ceinture de sécurité même si les cein-
tures de sécurité ne sont pas attachées.
Les coussins gonflables SRS avant
peuvent alors ne pas s’activer correcte-
ment lors d’une collision, ce qui pourrait
occasionner des blessures graves,
voire mortelles, en cas de collision.
Assurez-vous de toujours porter la cein-
ture de sécurité avec la rallonge de
ceinture de sécurité.

Précautions relatives aux coussins gonflables SRS

●

Ne fixez et n’appuyez rien sur des
zones telles que la planche de bord, le
tampon de volant ou encore la partie
inférieure du tableau de bord.
Ces objets peuvent se transformer en
projectiles lorsque les coussins gon-
flables SRS du conducteur, du passa-
ger avant et de protection des genoux
du conducteur se déploient.

●

Ne fixez rien sur des zones telles que
les portières, le pare-brise, les glaces
de portières, les montants avant ou
arrière, le brancard de pavillon et la poi-
gnée de maintien.

●

Véhicules non dotés du système Smart
key : N’accrochez pas d’objets lourds,
pointus ou durs, par exemple des clés
ou des accessoires, à la clé. Ces objets
pourraient empêcher le déploiement du
coussin gonflable SRS de protection
des genoux ou être projetés violem-
ment dans l’assise du siège du conduc-
teur par la force du déploiement, et
donc présenter un danger.

Précautions relatives aux coussins gonflables SRS

●

N’accrochez pas de cintres ni d’autres objets rigides sur les crochets
porte-vêtements. Tous ces objets pourraient se transformer en projectiles
et vous occasionner des blessures graves, voire mortelles, en cas de
déploiement des coussins gonflables SRS en rideau.

●

Si un recouvrement de vinyle est placé sur la zone de déploiement du
coussin gonflable SRS de protection des genoux, veillez à le retirer.

●

N’utilisez pas d’accessoires recouvrant les parties du siège où les cous-
sins gonflables SRS latéraux et le coussin gonflable SRS du coussin de
siège se déploient, car ces accessoires pourraient entraver le déploiement
des coussins SRS. De tels accessoires peuvent empêcher les coussins
gonflables latéraux et le coussin gonflable du coussin de siège de se
déployer correctement, rendre le système inopérant ou provoquer acci-
dentellement le déploiement des coussins gonflables latéraux et du cous-
sin gonflable du coussin de siège, occasionnant des blessures graves,
voire mortelles.

●

Ne frappez pas et n’appliquez pas une pression importante à l’emplace-
ment des composants de coussins gonflables SRS.
Cela peut provoquer un mauvais fonctionnement des coussins gonflables
SRS.

●

Ne touchez à aucun composant des coussins gonflables SRS immédiate-
ment après leur déploiement (gonflage), car ils pourraient être chauds.

●

Si vous avez de la difficulté à respirer après le déploiement des coussins
gonflables SRS, ouvrez une portière ou une glace pour laisser entrer l’air,
ou quittez le véhicule si vous pouvez le faire en toute sécurité. Dès que
possible, nettoyez tous les résidus afin d’éviter les irritations cutanées.

●

Si les emplacements de stockage des coussins gonflables SRS, tels que
le tampon de volant et les garnitures des montants avant et arrière, sont
endommagés ou fissurés, faites-les remplacer par votre concessionnaire
Toyota.

●

Ne placez aucun objet, par exemple un coussin, sur le siège du passager
avant. Cela disperserait le poids du passager, ce qui empêcherait le cap-
teur de le détecter correctement. Cela pourrait empêcher le déploiement
des coussins gonflables SRS du passager avant en cas de collision.
