Lexus LX570 (2021 year). Manual in english — page 32

WARNING

■

If both the ABS and the brake system warning lights remain on

Stop your vehicle in a safe place immediately and contact your Lexus dealer. The vehi-

cle will become extremely unstable during braking, and the ABS system may fail, which

could cause an accident resulting in death or serious injury.

■

If the tire pressure warning light comes on

Be sure to observe the following precautions. Failure to do so could cause loss of vehi-

cle control and result in death or serious injury.

●

Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pressure

immediately.

●

If the tire pressure warning light comes on even after tire inflation pressure adjust-

ment, it is probable that you have a flat tire. Check the tires. If the tire is flat, change to

the spare tire and have the flat tire repaired by the nearest Lexus dealer.

●

Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could lose

control of the steering wheel or the brakes.

■

If a blowout or sudden air leakage should occur

The tire pressure warning system may not activate immediately.

When trouble

WARNING

■

Maintenance of the tires

Each tire, including the spare (if provided), should be checked monthly when cold and

inflated to the inflation pressure recommended by the vehicle manufacturer on the

vehicle placard or tire inflation pressure label (tire and load information label). (If your

vehicle has tires of a different size than the size indicated on the vehicle placard or tire

inflation pressure label [tire and load information label], you should determine the

proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure moni-

toring system (TPMS-tire pressure warning system) that illuminates a low tire pressure

telltale (tire pressure warning light) when one or more of your tires is significantly

under-inflated. Accordingly, when the low tire pressure telltale (tire pressure warning

light) illuminates, you should stop and check your tires as soon as possible, and inflate

them to the proper pressure. Driving on a significantly under-inflated tire causes the

tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency

and tire tread life, and may affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a substitute for proper

tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure,

even if under-inflation has not reached the level to trigger illumination of the TPMS low

tire pressure telltale (tire pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning system) mal-

function indicator to indicate when the system is not operating properly. The TPMS

(tire pressure warning system) malfunction indicator is combined with the low tire pres-

sure telltale (tire pressure warning light). When the system detects a malfunction, the

telltale will flash for approximately one minute and then remain continuously illumi-

nated. This sequence will continue upon subsequent vehicle start-ups as long as the

malfunction exists. When the malfunction indicator is illuminated, the system may not

be able to detect or signal low tire pressure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a variety of reasons,

including the installation of replacement or alternate tires or wheels on the vehicle that

prevent the TPMS (tire pressure warning system) from functioning properly. Always

check the TPMS (tire pressure warning system) malfunction telltale after replacing one

or more tires or wheels on your vehicle to ensure that the replacement or alternate

tires and wheels allow the TPMS (tire pressure warning system) to continue to function

properly.

NOTICE

system may not operate properly.

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. 302)

●

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.

544

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.
