AVERTISSEMENT
■Précautions relatives aux coussins gonflables SRS
●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 mor-
telles 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.
●N'utilisez aucun accessoire de siège reco uvrant les zones de déploiement des cous-
sins gonflables latéraux SRS et du coussin gonflable de coussin de siège SRS, car il
risque de gêner le déploiement des coussi ns gonflables SRS. De tels accessoires
peuvent empêcher les coussins gonflables la téraux et le coussin gonflable de coussin
de siège SRS de s'activer correctement, désactiver le système ou entraîner le
déploiement accidentel des coussins gonfla bles latéraux et du coussin gonflable de
coussin de siège SRS, occasionnant de s blessures graves, voire mortelles.
●Évitez de faire subir des chocs ou des pr essions excessives aux parties autour des
composants de coussins gonflables SRS ou aux portes avant.
En effet, cela pourrait entraîner un dysfonctionnement des coussins gonflables SRS.
●Ne touchez aucun composant immédiatement après le déploiement (gonflage) des
coussins gonflables SRS, car ils peuvent être chauds.
●Ne fixez rien et ne posez rien sur des empla-
cements tels que la plan che de bord, la garni-
ture du volant et la partie inférieure du
tableau de bord.
Ces éléments peuvent se transformer en pro-
jectiles 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.
