When trouble arises
1Remove 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.
2 Install the spare tire and loosely
tighten each wheel nut by hand by
approximately the same amount.
When replacing an aluminum wheel with
an aluminum wheel, turn the wheel nuts
until the washers come into contact
with the disc wheel .
WARNING
■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 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, 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.
