WARNING

O

Take care because brake fluid can

harm your hands or eyes and damage

painted surfaces. If fluid gets on your

hands or in your eyes, flush the

affected area with clean water imme-

diately.

If you still experience discomfort, con-

sult a doctor.

Q

When working near the electric cool-

ing fan or radiator grille

Be sure the engine switch is off.

With the engine switch in ON, the elec-

tric cooling fan may automatically start to

run if the air conditioning is on and/or the

coolant temperature is high. (

P.341)

Q

Safety glasses

Wear safety glasses to prevent flying or

falling material, fluid spray, etc. from get-

ting in your eyes.

NOTICE

Q

If you remove the air cleaner filter

Driving with the air cleaner filter

removed may cause excessive engine

wear due to dirt in the air.

Q

If the fluid level is low or high

It is normal for the brake fluid level to go

down slightly as the brake pads wear or

when the fluid level in the accumulator is

high.

If the reservoir needs frequent refilling, it

may indicate a serious problem.

Q

When to replace your vehicle’s tires

Tires should be replaced if:

O

The treadwear indicators are showing on

a tire.

O

You have tire damage such as cuts, splits,

cracks deep enough to expose the fabric,

and bulges indicating internal damage

O

A tire goes flat repeatedly or cannot be

properly repaired due to the size or loca-

tion of a cut or other damage

If you are not sure, consult any authorized

Lexus retailer or Lexus authorized repairer,

or any reliable repairer.

Q

Tire life

Any tire over 6 years old must be checked

by a qualified technician even if it has sel-

dom or never been used or damage is not

obvious.

Q

Low profile tires (21-inch tires)

Generally, low profile tires will wear more

rapidly and tire grip performance will be

reduced on snowy and/or icy roads when

compared to standard tires. Be sure to use

snow tires on snowy and/or icy roads and

drive carefully at a speed appropriate for

road and weather conditions.

Q

If the tread on snow tires wears down

below 4 mm (0.16 in.)

The effectiveness of the tires as snow tires is

lost.

Rotate the tires in the order shown.

WARNING

Q

When inspecting or replacing tires

Observe the following precautions to

prevent accidents.

Failure to do so may cause damage to

parts of the drivetrain as well as danger-

ous handling characteristics, which may

lead to an accident resulting in death or

serious injury.

O

Do not mix tires of different makes,

models or tread patterns.

Also, do not mix tires of remarkably

different treadwear.

O

Do not use tire sizes other than those

recommended by Lexus.

O

Do not mix differently constructed

tires (radial, bias-belted or bias-ply

tires).

O

Do not mix summer, all season and

snow tires.

O

Do not use tires that have been used

on another vehicle.

Do not use tires if you do not know

how they were used previously.

NOTICE

Q

Driving on rough roads

Take particular care when driving on

roads with loose surfaces or potholes.

These conditions may cause losses in tire

inflation pressure, reducing the cushion-

ing ability of the tires. In addition, driving

on rough roads may cause damage to

the tires themselves, as well as the vehi-

cle’s wheels and body.

Q

Low profile tires (21-inch tires)

Low profile tires may cause greater dam-

age than usual to the tire wheel when

sustaining impact from the road surface.

Therefore, pay attention to the following:

O

Be sure to use proper tire inflation

pressure. If tires are under-inflated,

they may be damaged more severely.

O

Avoid potholes, uneven pavement,

curbs and other road hazards. Failure

to do so may lead to severe tire and

wheel damage.

Q

If tire inflation pressure of each tire

becomes low while driving

Do not continue driving, or your tires

and/or wheels may be ruined.

Tire rotation

346

6-3. Do-it-yourself maintenance



Vehicles with front and rear tires of
the same size



Vehicles with front and rear tires of
differing sizes

To equalize tire wear and help extend tire
life, Lexus recommends that tire rotation is
carried out approximately every 10000
km (6000 miles).
Do not fail to initialize the tire pressure
warning system after tire rotation.

Q

When rotating the tires

Make sure that the engine switch is OFF. If

the tires are rotated while the engine switch

is in ON, the tire position information will

not be updated.

If this accidentally occurs, either turn the

engine switch to OFF and then to ON, or

initialize the tire pressure warning system

after checking that the tire pressure is prop-

erly adjusted.

When run-flat tires are installed, the
vehicle can be driven for a maximum of
160 km (100 miles) at a speed below
80 km/h (50 mph) after any tire goes
flat. (However, the vehicle speed may
not increase to near 80 km/h [50
mph] depending on weather or driving
conditions.)

A run-flat tire has a

mark on

the sidewall.

Make sure to replace the flat tire before
the vehicle has been driven for near 160
km (100 miles). Also, do not use a repaired
tire.

Q

Run-flat tires

O

The run-flat tires are for only this vehicle.

Do not use the tires on other vehicles.

O

Do not mix run-flat tires and normal tires.

O

If non-genuine Lexus wheels are used, it

may be impossible to sufficiently demon-

strate the performance of run-flat tires.

Your vehicle is equipped with a tire
pressure warning system that uses tire
pressure warning valves and transmit-
ters to detect low tire inflation pressure
before serious problems arise.



If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and a
warning light. (

mation display.

Q

Routine tire inflation pressure checks

The tire pressure warning system does not

replace routine tire inflation pressure

checks. Make sure to check tire inflation

pressure as part of your routine of daily

vehicle checks.

Q

Situations in which the tire pressure

warning system may not operate prop-

erly

O

In the following cases, the tire pressure

warning system may not operate prop-

erly.

• If non-genuine Lexus wheels are used.

• A tire has been replaced with a tire that is

not an OE (Original Equipment) tire.

• A tire has been replaced with a tire that is

not of the specified size.

• Tire chains etc. are equipped.

• An auxiliary-supported run-flat tire is

equipped.

• If a window tint that affects the radio wave

signals is installed.

• If there is a lot of snow or ice on the vehi-

cle, particularly around the wheels or

wheel housings.

• If the tire inflation pressure is extremely

higher than the specified level.

• If wheels without tire pressure warning

valves and transmitters are used.

• If the ID code on the tire pressure warn-

ing valves and transmitters is not regis-

tered in the tire pressure warning

computer.

O

Performance may be affected in the fol-

lowing situations.

• Near a TV tower, electric power plant,

gas station, radio station, large display,

airport or other facility that generates

strong radio waves or electrical noise

• When carrying a portable radio, cellular

phone, cordless phone or other wireless

communication device

If tire position information is not correctly
displayed due to the radio wave conditions,
the display may be corrected by driving and
changing the radio wave conditions.

O

When the vehicle is parked, the time

taken for the warning to start or go off

could be extended.

O

When tire inflation pressure declines rap-

idly for example when a tire has burst, the

warning may not function.

Q

Warning performance of the tire pres-

sure warning system

The warning of the tire pressure warning

system will change in accordance with the

conditions under which it was initialized. For

this reason, the system may give a warning

even if the tire pressure does not reach a

low enough level, or if the pressure is higher

than the pressure that was adjusted to when

the system was initialized.

356

6-3. Do-it-yourself maintenance

When replacing tires or wheels, tire
pressure warning valves and transmit-
ters must also be installed.
When new tire pressure warning
valves and transmitters are installed,
new ID codes must be registered in the
tire pressure warning computer and
the tire pressure warning system must
be initialized. (



P.358)

Q

When replacing the tires and wheels

If the ID code of the tire pressure warning

valve and transmitter is not registered, the

tire pressure warning system will not work

properly. After driving for about 10 minutes,

the tire pressure warning light blinks for 1

minute and stays on to indicate a system

malfunction.

when performing the above procedure,
contact any authorized Lexus retailer or
Lexus authorized repairer, or any reliable
