■Ceintures de sécurité
Avec un chiffon ou une éponge, nettoyez à l’aide d’un savon doux et de
l’eau tiède. Vérifiez aussi les ceintures régulièrement pour vous assurer
qu’elles ne présentent pa s d’usure excessive, d’effilochage ou de cou-
pures.
Entretien et soin
ATTENTION
■Dommages et usure de la ceinture de sécurité
Vérifiez périodiquement le système de ceintures de sécurité. Assurez-vous qu’il
n’y a pas de coupures, d’effilochures ni de pièces desserrées. N’utilisez pas une
ceinture de sécurité endommagée avant qu’elle ne soit remplacée. Les ceintures
de sécurité endommagées ne peuvent pas protéger les occupants contre les
blessures graves, voire mortelles.
