■Replacing a flat tire
●Do not touch the disc wheels or the
area around the brakes immediately
after the vehicle has been driven.
After the vehicle has been driven the
disc wheels and the area around the
brakes will be extremely hot. Touching
these areas with hands, feet or other

●Failure to follow these precautions
could cause the wheel nuts to loosen
and the tire to fall of f, 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 76 ft • lbf (103 N •m,
10.5 kgf •m) as soon as possible after
changing wheels.
• 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.
• Do not attach a heavily damaged wheel ornament, as it may fly off the
wheel while the vehicle is moving.
