ATTENTION
■Précautions relatives aux coussins gonflables SRS
●Ne touchez à aucun composant des coussins gonflables SRS immédiatement
après leur déploiement (gonflage), car ils pourraient être chauds.
●Si vous avez de la difficulté à respirer après le déploiement des coussins gon-
flables 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, notamment le
tampon de volant, la porte de la boîte à gants et les garnitures des montants avant
et arrière, sont endommagés ou fissurés, faites-les remplacer par votre conces-
sionnaire Lexus.
■Modification et mise au rebut des composants du système de coussins gonflables
SRS
Ne mettez pas le véhicule au rebut et n’effectuez aucune des modifications suiva-
ntes sans d’abord consulter votre concessionnaire Lexus. Les coussins gonflables
SRS pourraient fonctionner de manière incorrecte ou se déployer (gonfler) acci-
dentellement, ce qui serait susceptible d’occasionner des blessures graves, voire
mortelles.
●Installation, retrait, démontage et réparation des coussins gonflables SRS
●Réparations, modifications, retrait ou remplacement du volant, du bloc d’instru-
mentation, du tableau de bord, des sièges ou du capitonnage des sièges, des
montants avant, latéraux ou arrière et des longerons du toit

l’habitacle
●Installation de lames de déneigement, de treuils, etc. sur la calandre avant (barre
