WARNING

■

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.

• Turn off the vehicle height control.

The vehicle height may change due to the automatic leveling function and you may

catch part of your body in the vehicle, resulting in an accident. (

P. 301)

●

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 97 ft

•

lbf (131 N

m, 13.4

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.

■

Replacing a flat tire for vehicles with power back door
In cases such as when replacing tires, make sure to turn off the power back door main

switch (

P. 130). Failure to do so may cause the back door to operate unintentionally

if the power back door switch is accidentally touched, resulting in hands and fingers

being caught and injured.

543

When trouble

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 nut washers until they come

into contact with the disc wheel.

Lower the vehicle.

Firmly tighten each nut two or three
times in the order shown in the illus-
tration.
