■Replacing a flat tire
Observe the following precautions to reduce the risk of death or serious injury.
●Never use oil or grease on the wheel bolts or wheel nuts.
The oil or grease can cause the wheel nuts to loosen, causing a serious accident.
Remove any oil or grease on the wheel bolts or wheel nuts.
●Have the wheel nuts tightened with a torque wrench to 76 ft•lbf (103 N•m, 10.5
kgf•m) as soon as possible after changing wheels.
Failure to follow these precautions could cause the nuts to loosen and the wheels
may fall off, which could lead to an accident causing death or serious injury.

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.
ATTENTION
■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.
