■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-

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.
