5-2. Steps to take in an emergency

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.

●

Do not attach a heavily damaged wheel ornament, as it may fly off the wheel while

the vehicle is moving.

●

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 ft°lbf (140 N°m,

14.3 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.
