CAUTION
Replacing a flat tire
Observe the following precautions.
Failure to do so may result in serious injury:
• Do not try to remove the wheel ornament by hand. Take due care in
handling the ornament to avoid unexpected personal injury.
• 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,
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 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 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 profes-
sional.

7927-2. Steps to take in an emergency
GS350/250_EE (OM30C36E)Remove any dirt or foreign
matter from the wheel contact
surface.
If foreign matter is on the wheel
contact surface, the wheel nuts
may loosen while the vehicle is in
motion, causing the tire to come
off.
Install the tire and loosely tighten each wheel nut by hand by
approximately the same amount.
When replacing an aluminum
wheel with a steel wheel,
tighten the wheel nuts until the
tapered portion comes into
loose contact with the disc
wheel seat.
When replacing an aluminum
wheel with an aluminum
wheel, turn the wheel nuts
until the washers come into
contact with the disc wheel.
