CAUTION
■Using the tire jack
Improper use of the tire jack may lead to death or injuries due to the vehicle sud-
denly falling off the jack.
●Do not use the tire jack for any purpose other than replacing tires or installing and
removing tire chains.
●Only use the tire jack that comes with this vehicle for replacing a flat tire.
Do not use it on other vehicles, and do not use other tire jacks for replacing tires
on this vehicle.
●Always check that the tire jack is securely set to the jack point.
●Do not put any part of your body under the vehicle supported by a jack.
●Do not start or run the engine while your vehicle is supported by the jack.
●Do not raise the vehicle while someone is in it.
●When raising the vehicle, do not put an object on or under the jack.
●Do not raise the vehicle to a height greater than that required to replace the tire.
●Use a jack stand if it is necessary to get under the vehicle.
Take particular care when lowering the vehicle to ensure that no one working on or
near the vehicle may be injured.
■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.
