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 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.■

switch ( P. 132). Failure to do so may cause the back door to operat e unintentionally if
the power back door switch is accidentally touched, resulting in hands and fingers
being caught and injured.
