CAUTION

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
body parts while changing a tire, etc. may result in burns.

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 acci-
dent. 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.
• 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 any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
