Entretien et soin■ Ceintures de sécurité
Nettoyez avec un chiffon ou une éponge humectée d'eau
savonneuse tiède. Profitez de l'occasion pour vérifier
régulièrement que les ceintures ne sont pas effilochées, entaillées,
ou ne paraissent pas exagérément usées.

AT T E N T I O N
■Détérioration et usure des ceintures de sécurité
Inspectez les ceintures de sécurité périodiquement. Contrôlez qu'elles ne
sont pas entaillées, effilochées, et que leurs ancrages ne sont pas
desserrés. N'utilisez pas une ceinture de sécurité défectueuse avant qu'elle
ne soit remplacée. Une ceinture de sécurité défectueuse n'apporte aucune
garantie de protection de l'occupant en cas d'accident.
Si la ceinture de sécurité est sortie de son
guide, repassez-la dedans avant de
l'utiliser.
