5-2. Steps to take in an emergency
CAUTION
nUsing the jack
Improper use of the jack may lead to death or serious injuries due to the
vehicle suddenly falling off the jack.
lDo not use the jack for any purpose other than replacing tires or install-
ing and removing tire chains.
lOnly use the jack that comes with this vehicle for replacing a flat tire.
Do not use it on other vehicles, an
d do not use other jacks for replac-
ing tires on this vehicle.
lAlways check that the jack is securely set to the jack point.
lDo not put any part of your body under the vehicle supported by a jack.
lDo not start or run the engine while your vehicle is supported by the
jack.
lDo not raise the vehicle while someone is in it.
lWhen raising the vehicle, do not put an object on or under the jack.
lDo not raise the vehicle to a hei ght greater than that required to
replace the tire.
lUse 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 will be injured.
nReplacing a flat tire
Observe the following precautions to reduce the risk of death or serious
injury.
lNever 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.
lHave 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 wheel may fall off, which could lead to an accident causing death
or serious injury.
