WARNING
■Replacing a tire
Observe the following precautions to reduce the risk of death or serious injury.
●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.
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.
●Do not attach a heavily damaged wheel orname nt, as it may fly off the wheel while the vehicle is moving.
