WARNING
●Ne laissez pas un enfant rester debout
devant le coussin gonflable passager
avant SRS ou s'asseoir sur les genoux
du passager avant.
●Ne laissez pas les occupants des
sièges avant voyager avec un objet sur
les genoux.
●Ne vous appuyez pas contre la porte,
le rail latéral de toit ou les montants
avant, latéraux et arrière.
●Ne laissez personne s'agenouiller sur
les sièges passagers en appui contre la
porte ou sortir la tête ou les mains à
l'extérieur du véhicule.
●Ne fixez rien et ne posez rien sur des
emplacements tels que la planche de
bord, la garniture du volant et la partie
inférieure du tableau de bord.
Ces éléments peuvent se transformer
en projectiles lorsque les coussins
gonflables conducteur, passager avant
et genoux SRS se déploient.
●Ne fixez rien aux portes, à la vitre du
pare-brise, aux vitres latérales, aux
montants avant et arrière, au rail latéral
de toit et à la poignée de maintien.
●Ne suspendez aucun cintre ou objet
dur aux crochets à vêtements. Tous
ces objets pourraient se transformer
en projectiles et causer des blessures
graves, voire mortelles en cas de
déploiement des coussins gonflables
rideaux SRS.
●Si un cache en vinyle est placé sur la
zone où le coussin gonflable de
genoux SRS se déploie, assurez-vous
de le retirer.

WARNING
●N'utilisez aucun accessoire de siège
recouvrant les zones de déploiement
des coussins gonflables latéraux SRS,
car il risque de gêner le déploiement
des coussins gonflables. De tels acces-
soires peuvent empêcher les coussins
gonflables latéraux de fonctionner
correctement, désactiver le système
ou entraîner le déploiement accidentel
des coussins gonflables latéraux,
occasionnant des blessures graves,
voire mortelles.
●Évitez de faire subir des chocs ou des
pressions excessives aux parties ren-
fermant les composants de coussins
gonflables SRS.
En effet, cela pourra it entraîner un dys-
fonctionnement des coussins gonfla-
bles SRS.
●Ne touchez aucun composant
immédiatement après le déploiement
(gonflage) des coussins gonflables
SRS, car ils peuvent être 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. Essuyez
tout résidu dès que possible afin
d'éviter d'éventuelles irritations de la
peau.
●Si les parties renfermant les coussins
gonflables SRS, comme les garnitures
du volant et des montants avant et
arrière, sont endommagées ou cra-
quelées, faites-les remplacer par votre
concessionnaire Lexus.
●Ne placez rien sur le siège du pas-
sager 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 correctement le
poids du passager. En conséquence,
les coussins gonflables frontaux SRS
du passager avant risquent de ne pas
se déployer en cas de collision.
■Modification et mise au rebut des
composants du système de coussins
gonflables SRS
Ne mettez pas votre véhicule au rebut et
ne procédez à aucune des modifications
suivantes sans consulter votre conces-
sionnaire Lexus. Les coussins gonflables
SRS peuvent ne pas fonctionner cor-
rectement ou se déployer (se gonfler)
accidentellement, provoquant la mort ou
de graves blessures.
●Installation, dépose, démontage et
réparation des coussins gonflables
SRS
●Réparations, modifications, dépose ou
remplacement du volant, du tableau
de bord, de la planche de bord, des
sièges ou de leur garnissage, des mon-
tants avant, latéraux et arrière ou des
rails latéraux de toit
●Réparations ou modifications des ailes
avant, du pare-chocs avant ou des
flancs de l'habitacle
●Installation d'un protège-calandre
(pare-buffle, pare-kangourou, etc.), de
chasse-neige, de treuils ou d'un
porte-bagages de toit
●Modifications du système de suspen-
sion du véhicule
●Installation d'appareils électroniques
tels que les émetteurs/récepteurs
radios mobiles et les lecteurs CD
●Modifications de votre véhicule pour
une personne atteinte d'un handicap
physique
