n t

ris

■

When the electric power steering

system warning light comes on

The steering wheel may become

extremely heavy.

When steering wheel operations are

heavier than usual, grip the steering

wheel firmly and operate it using more

force than usual.

■

If the tire pressure warning light

comes on

Be sure to observe the following precau-

tions. Failure to do so could cause a loss

of vehicle control and result in death or

serious injury.



Vehicles with a spare tire

●

Stop your vehicle in a safe place as

soon as possible. Adjust the tire infla-

tion pressure immediately.

●

If the tire pressure warning light comes

on even after tire inflation pressure

adjustment, it is probable that you have

a flat tire. Check the tires. If a tire is flat,

change it with the spare tire and have

the flat tire repaired by the nearest

Lexus dealer.

●

Avoid abrupt maneuvering and brak-

ing. If the vehicle tires deteriorate, you

could lose control of the steering

wheel or the brakes.



Vehicles with an emergency tire punc-

ture repair kit

●

Stop your vehicle in a safe place as

soon as possible. Adjust the tire infla-

tion pressure immediately.

●

If the tire pressure warning light comes

on even after tire inflation pressure

adjustment, it is probable that you have

a flat tire. Check the tires. If a tire is flat,

repair the flat tire by using emergency

tire puncture repair kit.

●

Avoid abrupt maneuvering and brak-

ing. 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.

WARNING

■

Maintenance of the tires

Each tire, including the spare (if pro-

vided), should be checked monthly when

cold and inflated to the inflation pressure

recommended by the vehicle manufac-

turer on the vehicle placard or tire infla-

tion pressure label (tire and load

information label). (If your vehicle has

tires of a different size than the size indi-

cated on the vehicle placard or tire infla-

tion 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

monitoring system (TPMS-tire pressure

warning system) that illuminates a low

tire pressure telltale (tire pressure warn-

ing light) when one or more of your tires

is significantly under-inflated. Accord-

ingly, 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 signifi-

cantly under-inflated tire causes the tire

to overheat and can lead to tire failure.

Under-inflation also reduces fuel effi-

ciency and tire tread life, and may affect

the vehicle’s handling and stopping abil-

ity.

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 illumina-

tion of the TPMS low tire pressure telltale

(tire pressure warning light).

318

7-2. Steps to take in an emergency

Your vehicle has also been equipped with

a TPMS (tire pressure warning system)

malfunction indicator to indicate when

the system is not operating properly. The

TPMS (tire pressure warning system)

malfunction indicator is combined with

the low tire pressure telltale (tire pres-

sure warning light). When the system

detects a malfunction, the telltale will

flash for approximately one minute and

then remain continuously illuminated.

This sequence will continue upon subse-

quent 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 func-

tioning 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

cations or makers, as the tire pressure

warning system may not operate prop-

erly.

Attach the sticker at a position
where it is easily seen from the
driver’s seat.

Check the specified tire inflation
pressure.

Tire inflation pressure is specified on the

label as shown. (

Start the engine. (

To inject the sealant and inflate the
tire, turn the compressor switch on.

Inflate the tire until the specified air
pressure is reached.

The tire pressure gauge will tempo-
rarily rise to 44-58 psi (300-400
kPa, 3.0-4.0 kg/cm

) and then

gradually decrease.
Approximately 1-5 minutes after
the switch is turned on, the tire
pressure gauge will display the
actual tire inflation pressure..

When checking the tire inflation pressure,

turn the compressor switch off. In order to

not over inflate the tire, check the tire infla-

tion pressure multiple times while inflating

the tire.
It takes approximately 5-20 minutes

(depending on ambient temperature) to

inflate the tire to the specified tire inflation

pressure. If the specified tire inflation pres-

sure is not reached after 25 minutes or

more, the tire cannot be repaired. Turn the

compressor switch off and contact your

Lexus dealer.
If the tire inflation pressure exceeds the

specified air pressure, let out some air to

adjust the tire inflation pressure. (

tion on the appropriate authorized waste

disposal method.

WARNING

■

When a tire is flat

Do not drive continuously on a flat tire.

Driving even a short distance with a flat

tire may damage the tire and wheel

beyond repair. If a flat tire is driven on

continuously, cracks may form in the

sidewall of the tire. If the emergency tire

puncture repair kit is used in this situa-

tion, the tire may explode.

■

When fixing the flat tire

●

Stop your vehicle in a safe and flat

area.

330

7-2. Steps to take in an emergency

WARNING

●

Do not touch the wheels or the area

around the brakes immediately after

the vehicle has been driven.

After the vehicle has been driven, the

wheels and the area around the brakes

may be extremely hot. Touching these

areas with hands, feet or other body

parts may result in burns.

●

Connect the valve and hose securely

with the tire installed on the vehicle.

●

If the hose is not properly connected to

the valve, air leakage may occur or

sealant may be sprayed out.

●

If the hose comes off the valve while

inflating the tire, there is a risk that the

hose will move abruptly due to air

pressure.

●

After inflation of the tire has com-

pleted, the sealant may splatter when

the hose is disconnected or some air is

let out of the tire.

●

Follow the operation procedure to

repair the tire. If the procedure is not

followed, the sealant may spray out.

●

Keep back from the tire while it is

being repaired, as there is a chance of

it bursting while the repair operation is

being performed. If you notice any

cracks or deformation of the tire, turn

off the compressor switch and stop the

repair operation immediately.

●

If the emergency tire puncture repair

kit is continuously operated for a long

time, the compressor may overheat.

Do not operate the compressor for 40

minutes or more continuously.

●

Parts of the emergency tire puncture

repair kit become hot during opera-

tion. Be careful when handling it during

and after operation. Do not touch the

metal parts around where the bottle

and compressor connect as they will

be extremely hot.

●

Do not attach the vehicle speed warn-

ing sticker to an area other than the

one indicated. If the sticker is attached

to an area where an SRS airbag is

located, such as the pad of the steering

wheel, it may prevent the SRS airbag

from operating properly.

■

Driving to spread the liquid sealant

evenly

Observe the following precautions to

reduce the risk of accidents.

Failing to do so may result in a loss of

vehicle control and cause death or seri-

ous injury.

●

Drive the vehicle carefully at a low

speed. Be especially careful when

turning and cornering.

●

If the vehicle does not drive straight or

you feel a pull through the steering

wheel, stop the vehicle and check the

following:

• Tire condition. The tire may have sepa-

rated from the wheel.

• Tire inflation pressure. If tire inflation

pressure is 19 psi (130 kPa, 1.3 kgf/cm

or bar) or below, this may indicate

severe tire damage.

WARNING

■

Installing the tire

Failure to follow these precautions could

cause the wheel bolts to loosen and the

tire to fall off, resulting in death or serious

injury.

●

The contact surfaces of the wheel bolt

and wheel are designed specifically to

fit together. When using wheels that

were installed when the vehicle was

shipped from the factory, use special-

ized Lexus genuine wheel bolts.

Do not use wheel bolts designed for

other models, model years or types

even if they are Lexus genuine parts. If

the vehicle does not have wheels that

were installed to the vehicle when it

was shipped from the factory, the fac-

tory-installed wheel bolts may not be

appropriate for the wheel.

Contact either the retailer where the

wheels were purchased or the manu-

facturer of the wheels for proper

installation advice.

●

Never apply oil or grease to the wheel

bolts or their contact surface on the

wheel

Doing so may cause the wheel bolts to

be tightened excessively, leading to

damage to the wheel bolts, the

threaded portion the wheel bolts install

, or the wheel.
