This information has been prepared in accordance with regulations
issued by the National Highway Traffic Safety Administration of the
U.S. Department of Transportation.
It provides the purchasers and/or prospective purchasers of Toyota
vehicles with information on uniform tire quality grading.

Your Toyota dealer will help answer any questions you may have as

you read this information.

■

DOT quality grades

All passenger vehicle tires must conform to Federal Safety Require-
ments in addition to these grades. Quality grades can be found
where applicable on the tire sidewall between tread shoulder and
maximum section width.

For example: Treadwear 200 Traction AA Temperature A

■

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 Stan-

dard 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.

rité américaines applicables aux véhicules à moteur (FMVSS208). Le
boîtier électronique de coussins gonflables (ECU) utilise les informa-

composition du système pour commander le déploiement des couss-
ins gonflables. Ces informations comprennent des informations sur la
gravité de la collision et les occupants. Le déploiement rapide des
coussins gonflables est obtenu au moyen d’une réaction chimique

Précautions avec les coussins gonflables SRS

Respectez les précautions suivantes concernant les coussins gonflables
SRS.
À défaut, des blessures graves, voire mortelles, pourraient s’ensuivre.

●

Le conducteur et tous les passagers à bord du véhicule doivent porter leur
ceinture de sécurité correctement.
Les coussins gonflables SRS sont des dispositifs de protection complé-
mentaires aux ceintures de sécurité.

●

Le coussin gonflable SRS conducteur se déploie avec une puissance con-
sidérable et peut occasionner des blessures graves, voire mortelles, nota-
mment lorsque le conducteur se trouve très près du coussin gonflable.
L’autorité fédérale chargée de la sécurité routière aux États-Unis, la
NHTSA (National Highway Traffic Safety Administration) conseille:
Sachant que la zone de danger pour le coussin gonflable conducteur se
trouve dans les premiers 2 à 3 in. (50 à 75 mm) du déploiement, placez-
vous à 10 in. (250 mm) du coussin gonflable conducteur pour garantir
une marge de sécurité suffisante. Cette distance est à mesurer entre le
moyeu du volant de direction et le sternum. Si vous êtes assis à moins de
10 in. (250 mm), vous pouvez changer votre position de conduite de plu-
sieurs façons:
• Reculez votre siège le plus possible, tout en continuant à pouvoir

atteindre confortablement les pédales.

• Inclinez légèrement le dossier du siège.

Bien que la conception des véhicules varie, de nombreux conducteurs
peuvent atteindre la distance de 10 in. (250 mm), même avec le siège
du conducteur tout en avant, simplement en inclinant légèrement le
dossier du siège. Si vous avez des difficultés à voir la route après avoir
incliné votre siège, utilisez un coussin ferme et antidérapant pour vous
rehausser ou, si votre véhicule est équipé du réglage en hauteur du
siège, remontez-le.

• Si votre volant de direction est réglable, inclinez-le vers le bas. Cela

vous permet d’orienter le coussin gonflable vers votre buste plutôt que
vers la tête et le cou.

Le siège doit être réglé selon les recommandations de la NHTSA ci-des-
sus, tout en conservant le contrôle des pédales et du volant, et la vue des
commandes au tableau de bord.

504

MIRAI_OM_USA_OM62073U

AVERTISSEMENT

■

Précautions avec les coussins gonflables SRS

●

Le coussin gonflable SRS passager avant se déploie également avec une
puissance 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 peut infliger des blessures graves,
voire mortelles, aux nourrissons et aux enfants mal assis et/ou mal
attachés. Installez dans un siège de sécurité enfant les enfants trop jeunes
pour pouvoir utiliser la ceinture de sécurité. Toyota recommande vivement
que tous les nourrissons et enfants soient installés dans les sièges arrière
du véhicule et convenablement attachés. Les sièges arrière sont plus sûrs
pour les nourrissons et les enfants que le siège passager avant.

●

N’installez jamais un siège de sécurité enfant type dos à la route sur le
siège passager avant, même si le témoin indicateur “AIR BAG OFF” est
allumé. En cas d’accident, la force exercée par le déploiement rapide du
coussin gonflable passager avant peut causer des blessures graves, voire
mortelles à un enfant, si le siège de sécurité enfant type dos à la route est
installé sur le siège passager avant.

●

Si vous attachez une rallonge de cein-
ture de sécurité aux boucles des cein-
tures de sièges avant, mais pas au
pêne de la ceinture de sécurité propre-
ment dite, les coussins gonflables SRS
frontaux déterminent que le conducteur
et le passager avant portent leur cein-
ture de sécurité, alors même qu’elle
n’est pas attachée. Dans ce cas, les
coussins gonflables SRS frontaux ris-
quent de ne pas se déployer correcte-
ment en cas de collision, causant des
blessures graves, voire mortelles.
Veillez à porter la ceinture de sécurité
avec la rallonge de ceinture de sécurité.

Précautions avec les coussins gonflables SRS

●

Ne pas s’asseoir sur le bord du siège et
ne pas s’appuyer contre la planche de
bord.

●

Ne pas laisser un enfant rester debout
devant le coussin gonflable SRS pas-
sager avant ni assis sur les genoux du
passager avant.

●

Ne pas laisser les occupants des sièges
avant voyager avec un objet sur les
genoux.

●

Ne pas s’appuyer contre la porte, contre
le rail latéral de toit ou contre les mon-
tants avant, latéraux et arrière.

●

Interdisez à quiconque de s’agenouiller
sur le siège passager en appui contre la
porte ou de sortir la tête ou les mains à
l’extérieur du véhicule.

506

MIRAI_OM_USA_OM62073U

AVERTISSEMENT

■

Précautions avec les coussins gonflables SRS

●

Ne pas suspendre aux crochets à vêtements un cintre nu ni aucun objet
dur ou tranchant. En cas de déploiement des coussins gonflables SRS
rideau, tous ces objets pourraient se transformer en projectiles et causer
des blessures graves, voire mortelles.

●

Si une housse en vinyle recouvre la partie où le coussins gonflable SRS
de genoux se déploie, veillez à l’enlever.

●

N’utilisez pour les sièges aucun accessoire venant recouvrir les parties où
se déploient les coussins gonflables SRS latéraux et le coussin gonflable
SRS d’assise de siège, car il risquerait de gêner le déploiement des cous-
sins gonflables SRS. De tels accessoires peuvent empêcher les coussins
gonflables SRS latéraux et d’assise de siège de s’activer correctement,
neutraliser le système ou provoquer le déploiement accidentel des couss-
ins gonflables SRS latéraux et d’assise de siège, provoquant ainsi des
blessures graves, voire mortelles.

●

Ne rien fixer ou disposer sur la planche
de bord, la garniture centrale du moyeu
de volant de direction et la partie
inférieure du tableau de bord.
Lors du déploiement des coussins gon-
flables SRS conducteur, passager
avant et de genoux, tout objet risque de
se transformer en projectile.

●

Ne rien fixer sur les parties telles que
les portes, la vitre de pare-brise, les vit-
res latérales, les montants avant et
arrière, les rails latéraux de toit et les
poignées de maintien.
(Sauf l’autocollant de limitation de
vitesse)

AVERTISSEMENT

■

Précautions avec les coussins gonflables SRS

●

Évitez de faire subir des chocs ou des pressions excessives aux parties
renfermant les composants des coussins gonflables SRS.
En effet, cela pourrait entraîner un mauvais fonctionnement des coussins
gonflables SRS.

●

Ne touchez aucun composant du système immédiatement après le
déclenchement (déploiement) des coussins gonflables SRS, car ils sont
alors encore très chauds.

●

Si vous avez des difficultés à respirer après le déploiement des coussins
gonflables SRS, ouvrez une porte ou une vitre pour faire entrer de l’air
frais, ou bien descendez du véhicule si cela ne présente pas de danger.
Retirez tout résidu dès que possible afin d’éviter d’éventuelles irritations
de la peau.

●

Si les parties renfermant les coussins gonflables SRS, telles que la garni-
ture centrale du volant de direction et les garnitures de montants avant et
arrière, apparaissent abîmées ou craquelées, faites-les remplacer par
votre concessionnaire Toyota.

●

Ne rien poser sur le siège du passager avant, comme un coussin par
exemple. Cela a pour conséquence de répartir le poids du passager sur
toute la surface du siège, ce qui empêche le capteur de détecter normale-
ment le poids du passager. En conséquence, les coussins gonflables SRS
frontaux du passager avant peuvent ne pas se déployer en cas de colli-
sion.
