WARNING

■

When adding washer fluid

Do not add washer fluid when the engine

is hot or running as washer fluid contains

alcohol and may catch fire if spilled on

the engine, etc.

NOTICE

■

Do not use any fluid other than

washer fluid

Do not use soapy water or engine anti-

freeze instead of washer fluid.

Doing so may cause streaking on the

vehicle’s painted surfaces, as well as

damaging the pump leading to problems

of the washer fluid not spraying.

6-3. Do-it-yourself maintenance

Check if the treadwear indicators are
showing on the tires. Also check the
tires for uneven wear, such as excessive
wear on one side of the tread.
Check the spare tire condition and
pressure if not rotated.

New tread
Worn tread
Treadwear indicator

The location of treadwear indicators is
shown by a “TWI” or “

” mark, etc.,

molded into the sidewall of each tire.
Replace the tires if the treadwear indica-
tors are showing on a tire.

■

When to replace your vehicle’s tires

Tires should be replaced if:

●

The treadwear indicators are showing on

a tire.

●

You have tire damage such as cuts, splits,

cracks deep enough to expose the fabric,

and bulges indicating internal damage.

●

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 with your Lexus

dealer.

■

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.

■

Maximum load of tire

Check that the number given by dividing

the maximum load by 1.10 of the replace-

ment tire is greater than 1/2 of the Gross

Axle Weight Ratings (GAWR) of either the

front axle or the rear axle, whichever is

greater.
For the GAWR, see the Certification Label.

For the maximum load of the tire, see the

load limit at maximum cold tire inflation

pressure mentioned on the sidewall of the

tire. (

Tire types

●

Summer tires

Summer tires are high-speed performance
tires best suited to highway driving under
dry conditions. Since summer tires do not
have the same traction performance as
snow tires, summer tires are inadequate for
driving on snow-covered or icy roads. For

Tires

Replace or rotate tires in accor-
dance with maintenance schedules
and treadwear.

driving on snow-covered roads or icy
roads, the use of snow tires is recom-
mended. When installing snow tires, be
sure to replace all four tires.

●

All season tires

All season tires are designed to provide
better traction in snow and to be adequate
for driving in most winter conditions as well
as for use year-round. All season tires,
however, do not have adequate traction
performance compared with snow tires in
heavy or loose snow. Also, all season tires
fall short in acceleration and handling per-
formance compared with summer tires in
highway driving.

●

Snow tires

For driving on snow-covered roads or icy
roads, we recommend using snow tires. If
you need snow tires, select tires of the
same size, construction and load capacity
as the originally installed tires. Since your
vehicle has radial tires as original equip-
ment, make sure your snow tires also have
radial construction. Do not install studded
tires without first checking local regula-
tions for possible restrictions. Snow tires
should be installed on all wheels.

■

If the tread on snow tires wears down

below 0.16 in. (4 mm)

The effectiveness of the tires as snow tires is

lost.

■

Checking the tire valves

When replacing the tires, check the tire

valves for deformation, cracks, and other

damage.

WARNING

■

When inspecting or replacing tires

Observe the following precautions to

prevent accidents.

Failure to do so may cause damage to

parts of the drive train as well as danger-

ous handling characteristics, which may

lead to an accident resulting in death or

serious injury.

●

Do not mix tires of different makes,

models or tread patterns.

Also, do not mix tires of remarkably

different treadwear.

●

Do not use tire sizes other than those

recommended by Lexus.

●

Do not mix differently constructed

tires (radial, bias-belted or bias-ply

tires).

●

Do not mix summer, all season and

snow tires.

●

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.

●

Do not tow if your vehicle has a spare

tire installed.

NOTICE

■

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.

■

If tire inflation pressure of each tire

becomes low while driving

Do not continue driving, or your tires

and/or wheels may be ruined.

6-3. Do-it-yourself maintenance

Rotate the tires in the order shown.

To equalize tire wear and extend tire life,
Lexus recommends that tire rotation is car-
ried out at the same interval as tire inspec-
tion.
Make sure to perform wheel position reg-
istration procedure after rotating the tires.
(



P.442)

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.
The tire pressure warning system of
this vehicle adopts a 2-type warning
system. (



P.471)



When “Adjust Pressure” is dis-
played on the multi-information dis-
play (Normal Warning)

A warning with the tire pressure warning
light and warning buzzer when there is an
unknown level of low tire pressure with the
appearance of the tire due to natural air
leakage as well as the pressure lowering
due to changes in the pressure according
to the outside temperature.



When “Immediately Check tire
when Safe” is displayed on the
multi-information display (Emer-
gency Warning)

A warning with the tire pressure warning
light and warning buzzer when there is a
known level of low tire pressure with the
appearance of the tire due to pressure sud-
denly lowering. (Ways of coping:

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.

■

Tire inflation pressure

●

It may take a few minutes to display the

tire inflation pressure after the engine

switch is turned to ON. It may also take a

few minutes to display the tire inflation

pressure after inflation pressure has been

adjusted.

●

Tire inflation pressure changes with tem-

perature. The displayed values may also

be different from the values measured

using a tire pressure gauge.

■

Situations in which the tire pressure

warning system may not operate prop-

erly

●

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.

• 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 tires not equipped with 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.

●

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 condi-

tions, the display may be corrected by

changing the location of the vehicle as

the radio wave conditions may change.

●

When the vehicle is parked, the time

taken for the warning to start or go off

could be extended.

●

When tire inflation pressure declines rap-

idly for example when a tire has burst, the

warning may not operate.

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.
