■Lorsque vous utilisez la ceinture du siège central de la troisième rangée de sièges
■Dommages et usure de la ceinture de sécurité
Vérifiez périodiquement le système de ceintures de sécurité. Vérifiez qu’il n’y a pas de
coupures, d’effilochures ni de pièces dess errées. N’utilisez pas une ceinture de sécu-
rité endommagée avant qu’elle ne soit re mplacée. Une ceinture de sécurité endom-
magée ne peut pas protéger les occupants contre des blessures graves, voire
mortelles.
N’utilisez pas la ceinture du siège central de la
troisième rangée de sièges si l’une des boucles
est détachée. Attacher une seule boucle pour-
rait occasionner des blessures graves, voire
mortelles, en cas de freinage ou de dérapage
brusques, ou d’accident.
