Reporting safety defects for
U.S. owners
If you believe that your vehicle has a
defect which could cause a crash or
could cause injury or death, you
should immediately inform the
National Highway Traffic Safety
Administration (NHTSA) in addi-
tion to notifying the Lexus Division
of Toyota Motor Sa les, U.S.A., Inc.
(Toll-free: 1-800-25-LEXUS).
If NHTSA receives similar com-
plaints, it may open an investiga-
tion, and if it finds that a safety
defect exists in a group of vehicles,
it may order a recall and remedy
campaign. However, NHTSA can-
not become involved in individual
problems between you, your dealer,
or Lexus Division of Toyota Motor
Sales, U.S.A., Inc.
To contact NHTS A, you may call
the Vehicle Safety Hotline toll-free
at 1-888-327-4236 (TTY: 1-800-
424-9153); go to
http://www.safer-
car.gov
; or write to: Administrator,
NHTSA, 1200 New Jersey Ave,
S.E., Washington, DC 20590. You

4529-1. For owners
Module de capteur de coussin gonflable
Coussins gonflables latéraux arrière
Capteurs d’impact latéral (portière avant)
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 gon-
flables en fonction des informations obtenues des capteurs et d’autres éléments affichés
dans le diagramme des composants du systèm e ci-dessus. Ces informations comprennent
des données relatives à la grav ité de l’accident et aux occupants. Au moment du déploie-
ment des coussins gonflables, une réaction chimique se produi t dans les gonfleurs de cous-
sin gonflable et les coussins gonflables se remplissent rapidement d’un gaz non toxique
pour aider à limiter le mouvement des occupants.

AVERTISSEMENT
■Précautions relatives aux coussins
gonflables SRS
Observez les précautions suivantes en
ce qui concerne les coussins gonflables
SRS.
Négliger de le faire pourrait occasionner
des blessures graves, voire mortelles.
●Le conducteur et tous les passagers du
véhicule doivent porter leur ceinture
de sécurité de la manière appropriée.
Les coussins gonflables SRS sont des
dispositifs supplémentaires qui doivent
être utilisés avec les ceintures de sécu-
rité.
●Le coussin gonflable SRS du conduc-
teur se déploie avec une force con-
sidérable et peut occasionner des
blessures graves, voire mortelles,
notamment 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 déploie-
ment du coussin gonflable. Pour
assurer une marge de sécurité suff-
isante, 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 maxi- male vous permettant d’atteindre
encore aisément les pédales.
