CAUTION
■Using the tire jack
Improper use of the tire jack may lead to death or injuries due to the
vehicle suddenly falling off the jack.
●Do not use the tire jack for any pu rpose 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 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 hei ght greater than that required to
replace the tire.
●Use a jack stand if it is necessary to get under the vehicle.
●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.
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 seri-
ous 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.
