WARNING
■When installing the tire
Failure to follow these precautions could
cause the wheel nuts to loosen and the
tire to fall off, resulting 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 tightened, lead-
ing 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.
●Have the wheel nuts tightened with a
torque wrench to 103.3 ft•lbf (140
N•m, 14.3 kgf•m) soon as possible
after changing wheels.
●Do not attach a heavily damaged
wheel ornament, as it may fly off the
wheel while the vehicle is moving.
●When installing a tire, only use wheel
nuts that have been specifically
designed for that wheel.
●If there are any cracks or deformations
in the bolt screws, nut threads or bolt
holes of the wheel, have the vehicle
inspected by your Lexus dealer.
■After using the tools
Before driving, make sure all the tools are
stored securely in place. Failure to do so
may cause injury in case of a collision or
sudden braking.
