CAUTION
Using the tire jack
Improper use of the tire jack may lead to death or serious injuries due to the
vehicle suddenly 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 replac-
ing 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 while it is supported
by the 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 work-
ing on or near the vehicle may be injured.
Replacing a flat tire
Do not attach a heavily damaged wheel ornament, as it may fly off the
wheel while the vehicle is moving.
Failure to follow these precautions could cause the wheel nuts to loosen
and the tire to fall off, resulting in death or serious injury.
• Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, causing a
serious accident. Remove any oil or grease from the wheel bolts or
wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 103 N
•m (10.5
kgf
•m, 76 ft•lbf) as soon as possible after changing wheels.
