7-2. Steps to take in an emergency
WARNING
●
Failure to follow these precautions
could cause the wheel nuts to
loosen and the tire to fall off, result-
ing 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 tight-
ened, 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 an accident and resulting in
death or serious injury. 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.
• When installing a tire, only use
wheel nuts that have been specifi-
cally designed for that wheel.
• If there are any cracks or deforma-
tions in the bolt screws, nut threads
or bolt holes of the wheel, have the
vehicle inspected by your Toyota
dealer.
• Do not attach a heavily damaged
wheel ornament, as it may fly off the
wheel while the vehicle is moving.

Observe the following precautions.
Failure to do so may result in seri-
ous injury:
• Do not try to remove the wheel
ornament by hand. Take due care in
handling the ornament to avoid
unexpected personal injury.
• Lower the spare tire completely to
the ground before removing it from
under the vehicle.
