CAUTION
■
Replacing a flat tire
●
Observe the following precautions.
Failure to do so may result in serious injury:
• Lower the spare tire completely to the ground before removing it from under the
vehicle.
• 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 nuts to loosen and the wheel may
fall off, which could lead to an accident causing 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 76 ft•lbf (103 N•m,
10.5 kgf•m) 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 your Lexus dealer.

7-2. Steps to take in an emergency
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, and the
tire may come off the vehicle.
Install the spare tire and loosely
tighten each nut by hand to approxi-
mately the same amount.
Turn the lug nuts until the washers come
into contact with the disc wheel.
Lower the vehicle.
