VEHICLE IDENTIFICATION

The vehicle identification number (VIN) is the legal
identifier for your vehicle. This number is on the left top
of the instrument panel and can be seen through the
windshield from outside.

This is the primary identification number for your Lexus. It is
used in registering the ownership of your vehicle.

INTRODUCTION

The vehicle identification number (VIN) is also on the
Certification Label.

The engine number is stamped on the engine block as
shown.

535

INTRODUCTION

THEFT PREVENTION LABELS

(U.S.A. ONLY)

Your new vehicle carries theft prevention labels which are
approximately 56 mm (2.20 in.) by 16 mm (0.63 in.).

The purpose of these labels is to reduce the incidence of
vehicle thefts by facilitating the tracing and recovery of parts
from stolen vehicles. The label is designed so that once it is
applied to a surface, any attempt to remove it will result in
destroying the integrity of the label. Transferring these labels
intact from one part to another will be impossible.

536

NOTICE

You should not attempt to remove the theft prevention
labels as it may violate certain state or federal laws.

DO–IT–YOURSELF SERVICE

PRECAUTIONS

If you perform maintenance yourself, be sure to follow the
correct procedure given in this Section.

You should be aware that improper or incomplete servicing
may result in operating problems.

Performing do–it–yourself maintenance during the warranty
period may af fect your warranty coverage. Read the separate
Lexus Warranty statement for details and suggestions.

This Section gives instructions only for those items that are
relatively easy for an owner to perform. As explained in
Section 5, there are still a number of items that must be
performed by a qualified technician with special tools.

For information on tools and parts for do–it–yourself
maintenance, see “Parts and tools” on page 542.

Utmost care should be taken when working on your vehicle to
prevent accidental injury . Here are a few precautions that you
should be especially careful to observe:

CAUTION

 When the engine is running, keep hands, clothing,

and tools away from the moving fan and engine drive
belt. (Removing rings, watches, and ties is
advisable.)

 Right after driving, the engine compartment — the

engine, radiator, exhaust manifold and power
steering fluid reservoir, etc. — will be hot. So be
careful not to touch them. Oil, other fluids and spark
plugs may also be hot.

 If the engine is hot, do not remove the radiator cap or

loosen the drain plugs to prevent burning yourself.

 Do not leave anything that may burn easily, such as

paper or rags, in the engine compartment.

 Do not smoke, cause sparks or allow open flames

around fuel or the battery. Their fumes are
flammable.

 Do not get under your vehicle with just the body jack

supporting it. Always use automotive jack stands or
other solid supports.

 Use eye protection whenever you work on or under

your vehicle where you may be exposed to flying or
falling material, fluid spray, etc.

 Be extremely cautious when working on the battery.

It contains poisonous and corrosive sulfuric acid.

540

NOTICE



Remember that battery and ignition cables carry high
currents or voltages. Be careful of accidentally
causing a short circuit.



Before closing the engine hood, check to see that you
have not forgotten any tools, rags, etc.



Do not drive with the air cleaner removed, or
excessive engine wear could result. Also backfiring
could cause a fire in the engine compartment.



Do not overfill automatic transmission fluid and
power steering fluid, or the transmission and power
steering could be damaged.



Be careful not to scratch the glass surface with the
wiper frame.

PROTECTING YOUR VEHICLE

FROM CORROSION

Proper care of your Lexus can help ensure long–term
corrosion prevention.

The most common causes of corrosion to your vehicle
are:

 The accumulation of road salt, dirt and moisture in

hard–to–reach areas under the vehicle.

 Chipping of paint or undercoating caused by minor

accidents or by stones and gravel.

The following conditions will cause or accelerate
corrosion of your vehicle, so it is important to keep your
vehicle, particularly the underside, as clean as possible
and to repair any damage to paint or protective coatings
as soon as possible.

 The presence of road salt or dust control chemicals, salt in

the air near the sea coast, industrial air pollution.

 High humidity, especially at temperatures just above

freezing point.

 Certain parts of your vehicle are wet or damp for an

extended period of time, even though other parts of the
vehicle are dry.

 Components of the vehicle which are prevented from

quick–drying due to lack of proper ventilation are exposed
to high ambient temperature.

To help prevent corrosion on your Lexus, follow these
guidelines:

Keep your vehicle clean by regular washing. In addition,

observe the following points.
 If you drive on salted roads in the winter or if you live near

the ocean, you should hose off the undercarriage at least
once a month to minimize corrosion.

 High pressure water or steam is effective for cleaning the

vehicle’s underside and wheel housings. Pay particular
attention to these areas as it is dif ficult to see all the mud and
dirt. It will do more harm than good to simply wet the mud
and debris without removing. The lower edge of doors,
rocker panels and frame members have drain holes which
should not be allowed to clog with dirt as trapped water in
these areas can cause corrosion.

 Wash the underside of the vehicle thoroughly when winter

is over.
See “Washing and waxing” on page 630 for more tips.
Check the condition of your vehicle’s paint and trim. If you

find any chips or scratches in the paint, touch them up
immediately to prevent corrosion from starting. If the chips or
scratches have gone through the bare metal, have a qualified
body shop make the repair.

629

BODY

Check the interior of your vehicle. Water and dirt can

accumulate under the floor mats and could cause corrosion.
Occasionally check under the mats to make sure the area is
dry. Be particularly careful when transporting chemicals,
cleansers, fertilizers, salt, etc. These should be transported in
proper containers. If a spill or leak should occur, immediately
clean and dry the area.

Use mud shields on your wheels. If you drive on salted or
gravel roads, mud shields help protect your vehicle. Full–size
shields, which come as near to the ground as possible, are the
best. We recommend that the fittings and the area where the
shields are installed be treated to resist corrosion. Your Lexus
dealer will be happy to assist in supplying and installing the
shields if they are recommended for your area.

Keep your vehicle in a well ventilated garage or a roofed
place. Do not park your vehicle in a damp, poorly
ventilated garage. If you wash your vehicle in the garage, or

if you drive it covered with water or snow, your garage may be
so damp as to cause corrosion. Even if your garage is heated,
a wet vehicle can corrode if the ventilation is poor.

WASHING AND WAXING

Washing your Lexus

Keep your vehicle clean by regular washing.

The following cases may cause weakness to the paint or
corrosion to the body and parts. W ash your vehicle as soon as
possible.

 When driving in a coastal area
 When driving on a road sprinkled with antifreeze
 When exposed to coal tar, tree sap, bird droppings and

carcass of an insect

 When driving in areas where there is a lot of smoke, soot,

dust, iron dust or chemical substances

 When the vehicle becomes remarkably dirty with dust and

mud

Hand–washing your Lexus

Work in the shade and wait until the vehicle body is not hot
to the touch.

1. Rinse off loose dirt with a hose. Remove any mud or road
salt from the underside of the vehicle or in the wheel wells.

2. Wash with a mild car–wash soap, mixed according to the
manufacturer’s instructions. Use a soft cotton mitt and keep it
wet by dipping it frequently into the wash water. Do not rub hard
— let the soap and water remove the dirt.

630

BODY

Fuel filler door: Do not apply water (high–pressure car wash,

for example) at or near the fuel tank inlet with the fuel filler door
opened. If the water enters the air vent, you may experience
trouble with refueling or rough engine idling.

Plastic wheel ornaments: The plastic wheel ornaments are
damaged easily by organic substances. If any organic
substance splashes an ornament, be sure to wash it off with
water and check if the ornament is damaged.

CAUTION

Do not attach the heavily damaged plastic wheel
ornament. It may fly off the wheel and cause accidents
while the vehicle is moving.

NOTICE

Do not use organic substances (gasoline, kerosene,
benzine or strong solvents), which may be toxic or
cause damage.

Aluminum wheels: Use only a mild soap or neutral detergent.
Urethane bumpers and side moldings: Wash carefully. Do

not scrub with abrasive cleaners. The bumper and side
molding faces are soft.

Road tar: Remove with turpentine or cleaners that are marked
safe for painted surfaces.

631

BODY

3. Rinse thoroughly — dried soap can cause streaking. In hot
weather you may need to rinse each section right after you
wash it.

4. To prevent water spots, dry the vehicle using a clean soft
cotton towel. Do not rub or press hard — you might scratch the
paint.

Automatic car wash

Your vehicle may be washed in an automatic car wash, but
remember that the paint can be scratched by some types of
brushes, unfiltered washing water, or the washing process
itself. Scratching reduces paint durability and gloss, especially
on darker colors. The manager of the car wash should be able
to advise you whether the process is safe for the paint on your
vehicle.

Waxing your Lexus

Polishing and waxing is recommended to maintain the
original beauty of your Lexus’ finish.

Apply wax once a month or if the vehicle surface does not repel
water well.

1. Always wash and dry the vehicle before you begin waxing,
even if you are using a combined cleaner and wax.

2. Use a good quality polish and wax. If the finish has become
extremely weathered, use a car–cleaning polish, followed by
a separate wax. Carefully follow the manufacturer’s
instructions and precautions. Be sure to polish and wax the
chrome trim as well as the paint.

3. Wax the vehicle again when water does not bead but
remains on the surface in large patches.

632

BODY

CLEANING THE INTERIOR

CAUTION

Do not wash the vehicle floor with water, or allow water
to get onto the floor when cleaning the vehicle interior
or exterior. Water may get into audio components or
other electrical components above or under the floor
carpet (or mat) and cause a malfunction; and it may
cause body corrosion.

Leather–trimmed Interior

Remove dirt using a soft cloth dampened with 5% solution of
neutral detergent for wool. Then thoroughly wipe off all traces
of detergent with a clean damp cloth.

After cleaning or whenever any part of the leather gets wet, dry
with a soft clean cloth. Allow the leather to dry in a ventilated
shaded area.

633

BODY

NOTICE



If a stain should fail to come out with a neutral
detergent, apply a cleaner that does not contain an
organic solvent.



Never use organic substances such as benzine,
alcohol or gasoline, or alkaline or acid solutions for
cleaning the leather as these could cause
discoloring.



Use of a nylon brush or synthetic fiber cloth, etc. may
scratch the fine grained surface of the leather.



Mildew may develop on soiled leather upholstery. Be
especially careful to avoid oil spots. T ry to keep your
upholstery always clean.



Long exposure to direct sunlight may cause the
leather surface to harden and shrink. Keep your
vehicle in a shaded area, especially in the summer.



The interior of your vehicle is apt to heat up on hot
summer days, so avoid placing on the upholstery
items made of vinyl or plastic or containing wax as
these tend to stick to leather when warm.



Improper cleaning of the leather upholstery could
result in discoloration or staining.

634

BODY

Non–leather Trim
(Part of door panels)

The non–leather trim may be easily cleaned with a mild
soap or detergent and water.

NOTICE

Do not use solvent, thinner, gasoline or window cleaner
on the interior.

First vacuum over the upholstery to remove loose dirt. Then,
using a sponge or soft cloth, apply the soap solution to the
synthetic leather. After allowing it to soak in for a few minutes
to loosen the dirt, remove the dirt and wipe off the soap with a
clean damp cloth. If all the dirt does not come off, repeat the
procedure. Commercial foaming–type cleaners are also
available which work well. Follow the manufacturer’s
instructions.

635

BODY

Carpets, Windows and Seat Belts

Begin by vacuuming thoroughly to remove as much dirt as
possible. Several types of foam cleaners are available; some
are in aerosol cans and others are powders or liquids which
you mix with water to produce a foam. To shampoo the
carpets, use a sponge or brush to apply the foam. Rub in
overlapping circles. Do not apply water — the best results are
obtained by keeping the carpet as dry as possible. Read the
shampoo instructions and follow them closely.

The seat belts may be cleaned with mild soap and water or
with lukewarm water.

Use a cloth or sponge. As you are cleaning, check the belts for
excessive wear, fraying or cuts.

636

NOTICE



Use a good foam–type shampoo to clean the carpets.



Do not use dye or bleach on the belts — it may
weaken them.



Do not use the belts until they become dry.



The windows may be cleaned with any household
window cleaner.



Do not apply detergent to or wet the automatic wiper
control sensor when cleaning the inside of the
windshield.



When cleaning the inside of the quarter and rear
windows, be careful not to scratch or damage the
wire antennas, heater wires or connectors.

NOTICE



Do not use organic substances (solvents, kerosene,
alcohol, gasoline, etc.) or alkaline or acidic solutions.
These chemicals can cause discoloring, staining or
peeling of the surface.



If you use cleaners or polishing agents, make sure
their ingredients do not include the substances
mentioned above.



If you use a liquid car freshener, do not spill the liquid
onto the vehicle’s interior surfaces. It may contain
the ingredients mentioned above. Immediately clean
any spill using the method mentioned above.

If you have any questions about the cleaning of your
Lexus, your local Lexus dealer will be pleased to answer
them.

638

Use a soft damp cloth for cleaning.
Soak a clean soft cloth in water or lukewarm water then lightly

wipe off any dirt.

RAIN CLEARING MIRRORS

The rear view mirrors have been coated to produce a “rain
clearing” effect. This coating causes the raindrops to
spread, clearing the driver’s rear view when it rains.

It is sufficient to wash the mirrors with water for day to day care.
The rain clearing effect is reduced in drizzle and light rain.
In the following cases, the rain clearing effect will be reduced

temporarily, but will gradually recover.

 After wiping dirt off the mirrors
 When the mirrors fog up

BODY

 After waxing your vehicle in an automatic car wash  After your vehicle has been parked for a long period in

underground parking lots, etc. where there is no direct

sunlight.
If you would like to restore the rain clearing effect to its normal

level immediately in the above cases, wash the mirrors with
neutral detergent, then rinse thoroughly.

639

BODY

NOTICE

To maintain the rain clearing ability, and prevent the
mirrors from being scratched, observe the following
precautions.



Do not use any glass cleaners that contain
compounds.



If ice should jam the mirror, do not scrape the mirror.
Use a spray de–icer to free the mirror.



Wash off any wax stuck to the mirrors with neutral
detergent and rinse thoroughly as any wax on the
surface of the mirrors can cause the rain clearing
effect to be lost.



Do not use any water repellents as they can destroy
the rain clearing effect. If any repellent gets stuck on
the surface of the mirrors, wash it off with neutral
detergent, then rinse thoroughly.

the suspected fuse straight out with the pull–out tool and
check it. If it has blown, push a new fuse into the clips.



Good

a. Look carefully at the fuse. If the thin wire is broken, the fuse
has blown. If you are not sure or if it is too dark to see, try
replacing the suspected fuse with one of the same value that
you know is good.

b. Only install a fuse with the amperage rating designated on
the fuse box lid.

If you do not have a spare fuse, in an emergency you can pull
out the “CIG”, “RADIO NO.1” or “SEA T HEATER” fuse, which
may be dispensable for normal driving, and use it if its
amperage rating is the same.

If you cannot use one of the same amperage, use one that is
lower, but as close to the rating as possible. If the amperage
is lower than that specified, the fuse might blow out again but
this does not indicate anything wrong. Be sure to get the
correct fuse as soon as possible and return the substitute to its
original clips.

615

ELECTRICAL COMPONENTS

It is a good idea to purchase a set of spare fuses and keep them
in your vehicle for emergencies.

If the new fuse immediately blows out, there is a problem with
the electrical system. Have your Lexus dealer correct it as
soon as possible.

CAUTION

Never use a fuse with a higher amperage rating, or any
other object, in place of a fuse. This may cause
extensive damage and possibly a fire.

CHECKING THE CARTRIDGE TYPE

Fuel type

Y our vehicle must use only unleaded gasoline.

To help prevent gas station mixups, your Lexus has a smaller
fuel tank opening. The special nozzle on pumps with unleaded
fuel will fit it, but the larger standard nozzle on pumps with
leaded gas will not.

NOTICE

Do not use leaded gasoline. Use of leaded gasoline will
cause the three–way catalytic converter to lose its
effectiveness and the emission control system to
function improperly. Also, this can increase
maintenance costs.

At a minimum, the gasoline you use should meet the
specifications of ASTM D4814 in the U.S.A. and CGSB

3.5–M93 in Canada.

550

ENGINE

Octane rating

Select Octane Rating 87 (Research Octane Number 91) or
higher. For improved vehicle performance, the use of
premium unleaded gasoline with an Octane Rating of 91
(Research Octane Number 96) or higher is recommended.

Use of unleaded fuel with an octane number or rating lower
than stated above will cause persistent heavy knocking. If
severe, this will lead to engine damage.

If your engine knocks...

If you detect heavy knocking even when using the
recommended fuel, or if you hear steady knocking while
holding a steady speed on level roads, consult your Lexus
dealer.

However, occasionally, you may notice light knocking for a
short time while accelerating or driving up hills. This is normal
and there is no need for concern.

Gasoline containing detergent additives

Lexus recommends the use of gasoline that contains
detergent additives to avoid build–up of engine deposits.

However, all gasoline sold in the U.S. contains detergent
additives to keep clean and/or clean intake systems.

Quality gasoline

Automotive manufacturers in the U.S., Europe and Japan
have developed a specification for quality fuel named
World–Wide Fuel Charter (WWFC) that is expected to be
applied world wide. The WWFC consists of four
categories that depend on required emission levels. In the
U.S., category 3 has been adopted. The WWFC improves
air quality by providing for better emissions in vehicle
fleets, and customer satisfaction through better vehicle
performance.

Cleaner burning gasoline

Cleaner burning gasoline, including reformulated
gasoline that contains oxygenates such as ethanol or
MTBE is available in many areas.

Lexus recommends the use of cleaner burning gasoline and
appropriately blended reformulated gasoline. These types of
gasoline provide excellent vehicle performance, reduce
vehicle emissions, and improve air quality.

551

ENGINE

Oxygenates in gasoline

Lexus allows the use of oxygenate blended gasoline
where the oxygenate content is up to 10% ethanol or 15%
MTBE. If y o u use gasohol in your Lexus, be sure that it has
an octane rating no lower than 87.

Lexus does not recommend the use of gasoline containing
methanol.

Gasoline containing MMT

Some gasoline contain an octane enhancing additive
called MMT (Methylcyclopentadienyl Manganese
Tricarbonyl).

Lexus does not recommend the use of gasoline that contains
MMT. If fuel containing MMT is used, your emission control
system may be adversely affected. The Malfunction Indicator
Lamp on the instrument cluster may come on. If this happens,
contact your Lexus dealer for service.

NOTICE



Do not use gasohol other than stated above. It will

cause fuel system damage or vehicle performance

problems.



If drivability problems are encountered (poor hot

starting, vaporizing, engine knock, etc.), discontinue

its use.



Take care not to spill gasohol during refueling.

Gasohol may cause paint damage.

Gasoline quality

In a very few cases, you may experience driveability problems
caused by the particular gasoline that you are using. If you
continue to have unacceptable driveability, try changing
gasoline brands. If this does not rectify your problem, then
consult your Lexus dealer.

FUEL PUMP SHUT OFF SYSTEM

The fuel pump shut off system stops supplying fuel to the
engine to minimize the risk of fuel leakage when the engine
stalls or an airbag inflates upon collision. To restart the engine
after the fuel pump shut off system activates, turn the ignition
switch to “ACC” or “LOCK” once and start it.

CAUTION

Inspect the ground under the vehicle before restarting
the engine. If you find that liquid has leaked onto the
ground, it is the fuel system that has been damaged and
it is in need of repair. In this case, do not restart the
engine.

FACTS ABOUT ENGINE OIL

CONSUMPTION

Functions of engine oil

Engine oil has the primary function of lubricating and cooling
the inside of the engine, and plays a major role in maintaining
the engine in proper working order.

Engine oil consumption

It is normal that an engine should consume some engine
oil during normal engine operation. The causes of oil
consumption in a normal engine are as follows.

 Oil is used to lubricate pistons, piston rings and cylinders.

A thin film of oil is left on the cylinder wall when a piston
moves downwards in the cylinder. High negative pressure
generated when the vehicle is decelerating sucks some of
this oil into the combustion chamber. This oil as well as
some part of the oil film left on the cylinder wall is burned by
the high temperature combustion gases during the
combustion process.

 Oil is also used to lubricate the stems of the intake valves.

Some of this oil is sucked into the combustion chamber
together with the intake air and is burned along with the fuel.
High temperature exhaust gases also burn the oil used to
lubricate the exhaust valve stems.

553

ENGINE

The amount of engine oil consumed depends on the
viscosity of the oil, the quality of the oil and the way the
vehicle is driven.

More oil is consumed by high–speed driving and frequent
acceleration and deceleration.

A new engine consumes more oil, since its pistons, piston rings
and cylinder walls have not become conditioned.

Oil consumption: Max. 1.0 L per 1000 km (1.1 qt./600 miles,

0.9 Imp. qt./600 miles)

When judging the amount of oil consumption, keep in
mind that the oil may have become diluted, making it
difficult to judge the true level accurately.

For example, if a vehicle is used for repeated short trips and
consumes a normal amount of oil, the dipstick may not show
any drop in the oil level at all, even after 1000 km (600 miles)
or more. This is because the oil is gradually becoming diluted
with fuel or moisture, making it appear that the oil level has not
changed.

The diluting ingredients evaporate out when the vehicle is then
driven at high speeds, as on an expressway , making it appear
that oil is excessively consumed after driving at high speeds.

NOTICE

Failure to check the oil level regularly could lead to
serious engine trouble due to insufficient oil.

Importance of engine oil level check

One of the most important points in proper vehicle
maintenance is to keep the engine oil at the optimum level so
that oil function will not be impaired. Therefore, it is essential
that the oil level be checked regularly. Lexus recommends that
the oil level be checked every time you refuel the vehicle.

For detailed information on oil level check, see “Checking the
engine oil level” described below.

554

USED ENGINE OIL

ENGINE

CAUTION

 Used engine oil contains potentially harmful

contaminants which may cause skin disorders such
as inflammation or skin cancer, so care should be
taken to avoid prolonged and repeated contact with
it. To remove used engine oil from your skin, wash
thoroughly with soap and water.

 Dispose of used oil and used oil filters only in a safe

and acceptable manner. Do not dispose of used oil
and used oil filters in household trash, in sewers or
onto the ground. Call your Lexus dealer or a service
station for information concerning recycling or
disposal.

 Do not leave used oil within the reach of children.

CHECKING THE ENGINE OIL LEVEL

With the engine at operating temperature and turned off,
check the oil level on the dipstick.

1. To get a correct reading, the vehicle should be on level
ground. After turning off the engine, wait a few minutes for the
oil to drain back into the bottom of the engine.

2. Pull the dipstick out, hold a rag under the end and wipe it
clean.

3. Reinsert the dipstick and push it in as far as it will go, or the
reading will not be correct.

when adding oil. The approximate quantity of oil needed to
raise the level between low line and full line on the dipstick is
indicated below for reference.

When the level reaches within the correct range, return the filler
cap and turn the cap clockwise until you hear a click.

CHECKING BRAKE FLUID

To check the fluid level, simply look at the see–through
reservoir. The level should be between the “MAX” and
“MIN” lines on the tank.

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
mechanical problem.

If the level is low, add FMVSS No.116 DOT 3 or SAE J1703
brake fluid to the brake reservoir.

NOTICE

If you spill some of the fluid, be sure to wipe it off to
prevent it from damaging the parts or paintwork.

Refilling brake fluid:

1. Turn the ignition switch off.

2. Depress the brake pedal more than 20 times (until the brake
pedal resistance decreases and pedal travel increases).

3. Remove the reservoir cap by hand. Add brake fluid up to the
“MAX” line.

If you do not follow the procedure above, the reservoir may
overflow.

Use only newly opened brake fluid. Once opened, brake fluid
absorbs moisture from the air, and excess moisture can cause
a dangerous loss of braking efficiency.

CAUTION

Take care when filling the reservoir because brake fluid
can harm your hands or eyes. If fluid gets on your hands
or in your eyes, flush the affected area with clean water
immediately. If you still feel uncomfortable with your
hands or eyes, go to the doctor.

CHECKING POWER STEERING

FLUID

The power steering fluid reservoir is located under the
right side engine compartment cover. Before checking
the power steering fluid, remove the cover. (For details,
see “Removing the engine compart covers” on page 538.)

Check the fluid level, simply look at the see–through
reservoir. If necessary, add automatic transmission fluid
DEXRON

If the vehicle has been driven around 80 km/h (50 mph) for 20
minutes (a little more in frigid temperatures), the fluid is hot
(60C – 80C or 140F – 175F). Y ou may also check the level
when the fluid is cold (about room temperature, 10C – 30C
or 50F – 85F) if the engine has not been run for about five
hours.

CHECKING TIRE INFLATION

PRESSURE

63PY020

The recommended cold tire inflation pressures,
tire sizes and the combined weight of occupants
and cargo (vehicle capacity weight) are described
on page 570 and 627. They are also described
on the tire and loading information label as
shown.

You should check the tire inflation pressure every two
weeks, or at least once a month. And do not forget
the spare!

The following instructions for checking tire
inflation pressure should be observed:

 The pressure should be checked only when the

tires are cold. If your vehicle has been parked

for at least 3 hours and has not been driven for
more than 1.5 km or 1 mile since, you will get an
accurate cold tire inflation pressure reading.

 If you cannot adjust the tire pressure when the

tires are cold, add 20 kPa (0.2 kgf/cm

psi) to 30 kPa (0.3 kgf/cm
to the front tires and rear tires than the cold tire
pressure, but never exceed the maximum cold tire
pressure molded on the tire sidewall.

2

or bar, 4.3 psi) more

or bar, 2.9

574

CHASSIS

 Always use a tire pressure gauge. The

appearance of a tire can be misleading. Besides,
tire inflation pressures that are even just a few
pounds off can degrade handling and ride.

 Do not bleed or reduce tire inflation pressure

after driving. It is normal for the tire inflation

pressure to be higher after driving.

 Never exceed the vehicle capacity weight.

Passengers and luggage weight should be located
so that the vehicle is balanced.

center of the valve and release the air to adjust.

575

CHASSIS

5.After completing the tire inflation pressure
measurement and adjustment, apply soapy water to
the valve and check for leakage.

6. Install the tire valve cap.
If a gauge and air pump are not available, have your

vehicle checked by your Lexus dealer.

CAUTION

Be sure to reinstall the tire valve caps. Without
the valve caps, dirt or moisture could get into
the valve core and cause air leakage. If the caps
have been lost, have new ones put on as soon
as possible.

NOTICE

Use only the original valve cap. If any other
valve cap is used, it may corrode or melt and
become difficult or impossible to remove.

576

CHASSIS

Incorrect tire inflation pressure may waste fuel, reduce
the comfort of driving, reduce tire life and make your
vehicle less safe to drive.

If a tire frequently needs refilling, have it checked by
your Lexus dealer.

CAUTION

Keep your tires properly inflated. Otherwise, the
following conditions may occur and cause an
accident resulting in death or serious injuries.

Low tire pressure (underinflation) —

 Excessive wear
 Uneven wear
 Poor handling
 Possibility of blowouts from an overheated

Uniform tire quality grading

This information has been prepared in accordance
with regulations issued by the National Highway
Traffic Safety Administration of the U.S.
Department of Transportation. It provides the
purchasers and/or prospective purchasers of
Lexus vehicles with information on uniform tire
quality grading.

Your Lexus dealer will help answer any questions
you may have as you read this information.

DOT quality grades — All passenger car tires must
conform to Federal Safety Requirements in
addition to these grades. Quality grades can be
found where applicable on the tire sidewall
between tread shoulder and maximum section
width. For example: Treadwear 200 Traction AA
Temperature A

Treadwear — The treadwear grade is a comparative

rating based on the wear rate of the tire when tested
under controlled conditions on a specified government
test course. For example, a tire graded 150 would
wear one and a half (1 — 1/2) times as well on the
government course as a tire graded 100. The relative
performance of tires depends upon the actual
conditions of their use, however, and may depart
significantly from the norm due to variations in driving
habits, service practices and differences in road
characteristics and climate.

Traction AA, A, B, C — The traction grades, from
highest to lowest, are AA, A, B and C, and they
represent the tire’s ability to stop on wet pavement
as measured under controlled conditions on specified
government test surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.

Warning: The traction grade assigned to this tire is
based on braking (straight ahead) traction tests and
does not include cornering (turning) traction.

582

Temperature A, B, C — The temperature grades are
A (the highest), B, and C, representing the tire’s
resistance to the generation of heat and its ability to
dissipate heat when tested under controlled conditions
on a specified indoor laboratory test wheel. Sustained
high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The
grade C corresponds to a level of performance which
all passenger car tires must meet under the Federal
Motor Vehicle Safety Standard No. 109. Grades B
and A represent higher levels of performance on the
laboratory test wheel than the minimum required by
law.

Warning: The temperature grade for this tire
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.

TYPES OF TIRES

Determine what kind of tires your vehicle is originally
equipped with.

1. Summer tires

Summer tires are high–speed capability 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 driving on snow–covered or icy roads, we
recommend using snow tires. If installing snow tires,
be sure to replace all four tires.

2. 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 all 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 performance compared
with summer tires in highway driving.

The details about how to distinguish summer tires
from all season tires are described on page 578.

CAUTION

 Do not mix summer and all season tires on

your vehicle as this can cause dangerous
handling characteristics, resulting in loss of
control.

 Do not use tires other than the manufacturer’s

designated tires, and never mix tires or
wheels of the sizes different from the
originals.
