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.

Refilling brake fluid:

1. Turn the ignition switch off.

2. Depress the brake pedal more than 40 times.

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

CAUTION

Take care when filling the reservoir because brake fluid can
harm your hands or eyes and damage painted surfaces. If
fluid gets in your hands or eyes, flush them with clean water.

NOTICE

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

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.

3. Make sure the fluid level is between ”MAX” and ”MIN”.
If the fluid level is lower than ”MIN”, have suspension fluid AHC

filled by your Lexus dealer.

The recommended cold tire pressures, tire size and the vehicle
capacity weight are given on the label.

You should check the tire pressures every two weeks, or at least
once a month. And don’t forget the spare! The pressure for the
spare tire should be 220 kPa (2.2 kgf/cm
tire pressure can reduce tire life and make your vehicle less safe to
drive.

Low tire pressure results in excessive wear, poor handling, reduced
fuel economy, and the possibility of blowouts from overheated
tires. Also, l o w tire pressure can cause poor sealing of the tire bead.
If the tire pressure is excessively low, there is the possibility of
wheel deformation and/or tire separation. So keep your tire
pressures at the proper level. If a tire needs frequent refilling, have
it checked by your Lexus dealer.

CHECKING TIRE PRESSURE

397

CHASSIS

High tire pressure produces a harsh ride, handling problems,
excessive wear at the center of the tire tread, and a greater
possibility of tire damage from road hazards.

The following instructions for checking tire 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 pressure reading.

 Always use a tire pressure gauge. The appearance of the tire

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

 Do not bleed or reduce tire pressure after driving. It is normal

for the tire pressure to be higher after driving.

 Never exceed the vehicle capacity weight. The passengers and

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

 Be sure to r einstall 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.

63X005

ROTATING TIRES

To equalize tire wear and help extend tire life, Lexus
recommends that you rotate your tires approximately every

398

12000 km (7500 miles). However, the most appropriate timing
for tire rotation may vary according to your driving habits and
road surface conditions.

The wheel assemblies must be rotated as illustrated above.
When rotating tires, check for uneven wear and damage. Abnormal

wear is usually caused by incorrect tire pressure, improper wheel

Worn tread

Replace the tires when the tread wear indicators show. The
location of the tread wear indicators is shown by the marks
molded on the sidewall of each tire.

The tires on your Lexus have built–in tread wear indicators to help
you know when the tires need replacement. When the tread depth
wears to 1.6 mm (0.06 in.) or less, the indicators will appear. I f y o u
can see the indicators in two or more adjacent grooves, the tire
should be replaced.

The effectiveness of snow tires is lost if the tread wears down
below 4 mm (0.16 in.).

CHASSIS

If you have tire damage such as cuts, splits, cracks deep enough
to expose the fabric, or bulges indicating internal damage, the
tire should be replaced.

If a tire often goes flat or cannot be properly repaired due to the size
or location of a cut or other damage, it should be replaced. If you
are not sure, consult with your Lexus dealer.

If an air loss occurs while driving, do not continue driving with a
deflated tire. Driving even a short distance can damage a tire
beyond repair.

Any tires which are over 6 years old must be checked by a
qualified technician even if damage is not obvious.

Tires deteriorate with age even if they have never or seldom been
used.

This also applies to the spare tire and tires stored for future use.

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 vehicle tires must conform
to Federal Safety Requirements in addition to these grades.
These quality grades are molded on the sidewall.

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.

T raction A, B , C – The traction grades, from highest to lowest, are
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.

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

T emperature 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 grades for this tire are 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.

Tire selection

When replacing a tire, use only the same size and construction
as originally installed and with the same or greater load
capacity.

Using any other size or type of tire may seriously affect handling,
ride, speedometer/odometer calibration, ground clearance, and
clearance between the body and tires or snow chains.

Do not mix radial, belted, or conventional tires on your vehicle.
Do not use tires or wheels other than the manufacturer’s

recommended size.

It can cause dangerous handling characteristics, resulting in loss of
control. If you need to change from conventional tires to radial tires
or vice versa, replace them as a set.

400

INSTALLING SNOW TIRES AND

CHAINS

When to use snow tires or chains

Snow tires or chains are recommended when driving on snow
or ice.

On wet or dry roads, conventional or radial tires provide better
traction than snow or studded tires.

Snow tire selection

If you need snow tires, select the same size, construction and
load capacity as the original tires on your Lexus.

Do not use tires other than stated above. Since your vehicle has
radial tires as original equipment, make sure your snow tires also
have radial construction. Do not install studded tires without first
checking local regulations for possible restrictions.

Snow tire installation

Snow tires should be installed on all wheels.

Installing snow tires on the rear wheels only can lead to an excessive
difference in road grip capability between the front and rear tires
which could cause loss of vehicle control.

CHASSIS

401

A: Diameter of side chain 5.0 (0.20)
B: Width of side chain 18.0 (0.71)
C: Length of side chain 46.1 (1.81)
D: Diameter of cross chain 6.0 (0.24)
E: Width of cross chain 22.0 (0.87)
F: Length of cross chain 37.5 (1.48)

402

Regulations regarding the use of tire chains vary according to
location or type of road. Always check the local regulations
before installing chains.

Chain installation

Install the chains on the rear tires as tightly as possible. Do not
use tire chains on the front tires. Retighten chains after driving

0.5 – 1.0 km (1/4 – 1/2 mile).

When installing chains on your tires, carefully follow the
instructions of the chain manufacturer.

If wheel covers are used, they will be scratched by the chain band,
so remove the covers before putting on the chains.

CAUTION

 Do not exceed 50 km/h (30 mph) or the chain

manufacturer’s recommended speed limit, whichever is
lower.

 Drive carefully avoiding bumps, holes, and sharp turns,

which may cause the vehicle to bounce.

 Avoid sharp turns or locked–wheel braking, as use of

chains may adversely affect vehicle handling.

403

CHASSIS

REPLACING WHEELS

When to replace your wheels

If you have wheel damage such as bending, cracks or heavy
corrosion, the wheel should be replaced.

If you fail to replace damaged wheels, a tire may slip off a wheel or
they may cause loss of handling control.

Replacement with used wheels is not recommended as they may
have been subjected to rough treatment or high mileage and could
fail without warning. Also, bent wheels which have been
straightened may have hidden structural damage and therefore
should not be used. Never use an inner tube in a leaking wheel
which is designed for a tubeless tire.

Wheel selection

When replacing wheels, care should be taken to ensure that they
are equivalent to those removed in load capacity, diameter, rim
width, and offset.

Correct replacement wheels are available at your Lexus dealer.
A wheel of a different size or type may adversely affect handling,

wheel and bearing life, brake cooling, speedometer/odometer
calibration, stopping ability, headlight aim, bumper height, vehicle
ground clearance, and tire or snow chain clearance to the body and
chassis.

CAUTION

ALUMINUM WHEEL

PRECAUTIONS

 After driving your vehicle the first 1600 km (1000 miles), check

that the wheel nuts are tight.

 If you have rotated, repaired, or changed your tires, check that

the wheel nuts are still tight after driving 1600 km (1000 miles).

 When using tire chains, be careful not to damage the aluminum

wheels.

 Use only the Lexus wheel nuts and wrench designed for your

aluminum wheels.

 When balancing your wheels, use only Lexus balance weights

or equivalent and a plastic or rubber hammer.

 As with any wheel, periodically check your aluminum wheels

for damage. If damaged, replace immediately.

SUSPENSION AND CHASSIS

Do not modify the suspension/chassis with lift kits, spacers,
springs, etc. It can cause dangerous handling characteristics,
resulting in loss of control.

404

REPORTING SAFETY DEFECTS

FOR U.S. OWNERS

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 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 difficult to see all the mud and dirt. It will
do more harm than good to simply wet the mud and debris
without removing them. 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” 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.

433

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 in covered
with water or snow, your garage may be so damp it will 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. Wash your vehicle as soon as possible.

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

carcass of an insect.

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

dust, iron dust and chemical substance

 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.

434

BODY

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.

NOTICE

Do not use gasoline or strong solvents, which may be toxic or
cause damage.

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

NOTICE

To prevent damage to the antenna, make sure it is retracted
before driving your vehicle through an automatic car wash.

Your vehicle may be washed in an automatic car wash, but
remember that the paint can be scratched by some type 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.

Once a month or if the vehicle does not repel water well, apply wax.

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.

435

BODY

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

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 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.

436

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. Try 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.

Synthetic Leather Areas
(Part of door panels)

The synthetic leather areas may be easily cleaned with a mild
soap or detergent and water.

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.

NOTICE

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

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.

NOTICE

 Use a good foam–type shampoo to clean the carpets.
 Do not use dye or bleach on the belts – it may weaken them.
 The windows may be cleaned with any household window

cleaner.

 When cleaning the inside of the rear window, be careful not

to scratch or damage the heater wires.

Air Conditioning Control Panel, Car Audio,
Instrument Panel, Console Panel, and Switches

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

off any dirt.

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

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 ”CIGAR”, ”DOME” or ”A·C” 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 lower than, but
as close as possible to, the amperage. 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.

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.

424

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

ENGINE

FUEL

Fuel type

Your 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 nozzle on pumps with leaded gas will not.

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.

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.

Octane rating

Select premium unleaded gasoline with an Octane Rating of 91
(Research Octane Number 96) or higher for optimum engine
performance. However, if such premium type cannot be
obtained, you may temporarily use unleaded gasoline with an
Octane Rating as low as 87 (Research Octane Number 91).

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, now and then, you may notice light knocking for a short
time while accelerating or driving up hills. This is no cause for
concern.

Gasolines containing detergent additives

Lexus recommends use of gasolines that contain detergent
additives to avoid build–up of engine deposits.

For further details, ask your Lexus dealer or a local gasoline retailer.

379

ENGINE

Improved gasolines

The American Automobile Manufacturers Association
(AAMA) has developed a specification of improved gasolines.
The AAMA specification offers optimal fuel information for
better vehicle performance and better protection of your
engine.

Lexus recommends the use of gasolines that meet the AAMA
specification, if available, for improved drivability and emission
control system.

Gasolines containing MTBE

Gasolines that contain MTBE (Methyl Tertiary–Butyl Ether)
are available in the market. If you use a gasoline mixed with
MTBE, make certain that it does not contain more than 15% of
MTBE.

If the use of gasolines containing MTBE causes poor drivability
and/or poor fuel economy, you should stop using them.

Gasolines containing MMT

Some gasolines contain an octane–enhancing additive called
MMT (methylcyclopentadienyl manganese tricarbonyl).

Lexus does not recommend the use of gasolines that contain MMT.
If fuels containing MMT are 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.

Gasolines containing alcohol

Gasohol is a mixture of gasoline and ethanol. If you use gasohol
in your Lexus, be sure that it is unleaded, has an octane rating
no lower than 87 and does not contain more than 10% ethanol.
Lexus does not recommend the use of gasolines containing
methanol.

If you use gasoline containing methanol, use only gasoline meeting
the requirements above and also containing less than 5% methanol
with cosolvents and corrosion inhibitors for methanol.

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.

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.

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.

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.

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.

NOTICE

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

For detailed information on oil level check, see ”Checking the
engine oil level” on page 383.

CHECKING THE ENGINE OIL

LEVEL

62X001d

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

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

2. Pull out the dipstick, and wipe it clean with a rag.

3. Standing up on the left side of the vehicle, reinsert the dipstick
in the direction so that the ”ENGINE OIL” on top should be read
correctly and push it in as far as it will go, or the reading will not be
correct.

NOTICE

Avoid overfilling, or the engine could be damaged. Check the
oil level on the dipstick once again after adding the oil.

62L005

Temperature range anticipated before next oil change

SAE 5W–30 is the best choice for your vehicle, for good fuel
economy, and good starting in cold weather.

If you use SAE 10W–30 engine oil in extremely low
temperatures, the engine may become difficult to start, so SAE
5W–30 engine oil is recommended.

Engine oil selection

Use API SH, ”Energy–Conserving II” or SJ, ”Energy–Conserving”
multigrade engine oil or ILSAC multigrade engine oil.

CHECKING THE ENGINE

COOLANT LEVEL

62X003d

1

Radiator cap 2Upper line 3Lower line



Park the vehicle at a level spot and look at the see–through
coolant reservoir when the engine is cool. The coolant level is
satisfactory if it is between the upper and lower lines on the
tank. If the level is low, add ethylene–glycol type coolant.

The coolant level in the reservoir will vary with engine coolant
temperature. However, if the level is on or below the lower line, add
coolant to bring the level up to the upper line.

Use only ethylene–glycol type coolant. It will prevent freezing and
corrosion. Neither supplemental inhibitors nor additives are
needed nor recommended. (For information on ethylene–glycol
coolant, see also ”Engine coolant selection” described below.)

ENGINE

If the coolant level drops within a short time after replenishing,
there may be a leak in the system. Visually check the radiator,
hoses, radiator cap, drain cock and water pump.

If you can find no leak, have your Lexus dealer test the radiator cap
pressure and check for leaks in the cooling system.

CAUTION

To prevent burning yourself, do not remove the radiator cap
when the engine is hot.

387

ENGINE

Engine coolant selection

Your coolant must contain ethylene–glycol antifreeze. In addition
to preventing freezing and subsequent damage to the engine, this
will also prevent corrosion. Further supplemental inhibitors or
additives are neither needed nor recommended.

Read the antifreeze container for information on freeze protection.
Follow the manufacturer’s directions for how much to mix with
water. The total capacity of the cooling system is given on page 378.
We recommend 50% solution be used for your Lexus, or a sufficient
quantity to provide protection to about –35C (–31F).

NOTICE

Do not use alcohol type antifreeze or plain water alone.

MAINTENANCE

MAINTENANCE REQUIREMENTS

Your Lexus vehicle has been designed to have fewer maintenance
requirements with longer service intervals to save both your time
and money. However, each regular maintenance as well as
day–to–day care is more important than ever before to ensure
smooth, trouble–free, safe, and economical driving.

It is the owner’s responsibility to make sure the specified
maintenance, including general maintenance services, is
performed. Note that both the new vehicle and emission control
system warranties specify that proper maintenance and care must be
performed. See the Owner’s Guide, Owner’s Manual Supplement
or Warranty Booklet for complete warranty information.

General maintenance

General maintenance items are those day–to–day care practices that
are important to your vehicle for proper operation. It is the owner’s
responsibility to ensure that the general maintenance items are
performed regularly.

These checks or inspections can be done either by yourself or your
Lexus dealer.

Scheduled maintenance

The scheduled maintenance items listed in the ”Owner’s Manual
Supplement/Maintenance Schedule” are those required to be
serviced at regular intervals.

For details of your maintenance schedule, read the separate
”Owner’s Manual Supplement/Maintenance Schedule”.

It is recommended that any replacement parts used for
maintenance or for the repair of the emission contr ol system be
Lexus supplied.

The owner may elect to use non–Lexus supplied parts for
replacement purposes without invalidating the emission control
system warranty. However, use of replacement parts which are
not of equivalent quality may impair the effectiveness of the
emission control systems.

You may also elect to have maintenance, replacement, or repair
of the emission control devices and system performed by any
automotive repair establishment or individual without
invalidating this warranty. See Owner’s Guide, Owner’s
Manual Supplement or Warranty Booklet for complete
warranty information.

Where to go for service?

Lexus technicians are well–trained specialists and are kept up to
date with the latest service information through technical bulletins,
service tips, and in–dealership training programs. They are well
informed about the operation of all the systems on your vehicle.

You can be confident that your Lexus dealer’s service department
performs the best job to meet the maintenance requirements of your
vehicle – reliably and economically.

361

MAINTENANCE

Your copy of the repair order is proof that all required maintenance
has been performed for warranty coverage. And if any problems
should arise with your vehicle while under warranty, your Lexus
dealer will promptly take care of it. Again, be sure to keep a copy
of the repair order for any service performed on your Lexus.

What about do–it–yourself maintenance?

Many of the maintenance items are easy to do yourself, if you have
a little mechanical ability and a few basic automotive tools. Simple
instructions for how to perform them are presented in Section 6.

If you are a skilled do–it–yourself mechanic, the Lexus service
manuals are recommended. Please be aware that do–it–yourself
maintenance can affect your warranty coverage. See your Owner’s
Guide, Owner’s Manual Supplement or Warranty Booklet for the
details.

IN CASE OF AN EMERGENCY

IF YOUR VEHICLE WILL NOT

START

(a) Simple checks

Before making these checks, make sure you have followed the
correct starting procedure instructions in ”How to start the engine”
on page 259 and that you have sufficient fuel. Since your vehicle
is equipped with the engine immobiliser system, also check whether
the other keys will start the engine. If they work, your key may be
broken. Have the key checked at your Lexus dealer. If none of your
keys work, the system is possibly broken. Call your Lexus dealer.
See ”Keys” on page 7.

If the engine is not turning over or is turning over too slowly –

1. Check that the battery terminals are tight and clean.

2. If the battery terminals are O.K., switch on the interior light.

3. If the light is out, dim or goes out when the starter is cranked, the
battery is discharged. You may try jump starting. See ”(c) Jump
starting” for further instruction.

If the light is O.K., but the engine still will not start, it needs
adjustment or repair. Call a Lexus dealer, Roadside Assistance or
Customer Service Assistance. (See ”Foreword”.)

NOTICE

Do not pull– or push–start the vehicle. It may damage the
vehicle or cause a collision when the engine starts. Also the
three–way catalytic converter may overheat and become a fire
hazard.

”(b) Starting a flooded engine” for further instructions.

2. If the engine still will not start, it needs adjustment or repair. Call
a Lexus dealer, Roadside Assistance or Customer Service
Assistance. (See ”Foreword”.)

If the engine turns over at its normal speed but will not start –

1. The engine may be flooded because of repeated cranking. See

329

IN CASE OF AN EMERGENCY

(b) Starting a flooded engine

If the engine will not start, your engine may be flooded because
of repeated cranking.

If this happens, turn the key to ”START” with the accelerator pedal
held down. Continue this operation for 30 seconds and then stop
cranking. Then try starting the engine with your foot off the
accelerator pedal.

If the engine does not start after 30 seconds of cranking, release the
key, wait a few minutes and try again.

If the engine still will not start, it needs adjustment or repair. Call
a Lexus dealer. Roadside Assistance or Customer Service
Assistance. (See ”Foreword”.)

NOTICE

Do not crank for more than 30 seconds at a time. This may
overheat the starter and wiring systems.

330

(c) Jump starting

To avoid serious personal injury and damage to your vehicle
which might result from battery explosion, acid burns,
electrical burns, or damaged electronic components, these
instructions must be followed precisely.

If you are unsure about how to follow this procedure, we strongly
recommend that you seek help from your Lexus dealer, Roadside
Assistance or Customer Service Assistance. (See ”Foreword”.).

CAUTION

 Batteries contain sulfuric acid which is poisonous and

corrosive. Wear protective safety glasses when jump

starting, and avoid spilling acid on your skin, clothing, or

vehicle.
 If you should accidentally get acid on yourself or in your

eyes, remove any contaminated clothing and flush the

affected area with water immediately . Then get immediate

medical attention. If possible, continue to apply water with

a sponge or cloth while en route to the medical office.
 The gas normally produced by a battery will explode if a

flame or spark is brought near. Use only standardized

jumper cables and do not smoke or light a match while

jump starting.

IN CASE OF AN EMERGENCY

NOTICE

The battery used for boosting must be 12 V. Do not jump start
unless you are sure that the booster battery is correct.

JUMP STARTING PROCEDURE

1. If the booster battery is installed in another vehicle, make sure
the vehicles are not touching. Turn off all unnecessary lights and
accessories.

332

2. If required, remove all the vent plugs from the booster battery.
Lay a cloth over the open vents on the booster battery. (This helps
reduce the explosion hazard, personal injuries and burns.)

If the booster battery is an extended maintenance interval battery,
it is not necessary to remove the vent plugs.

3. If the engine in the vehicle with the booster battery is not
running, start it and let it run for about 5 minutes. During jump
starting, run the engine at about 2000 rpm with the accelerator pedal
lightly depressed.

4. Locate positive (+) and negative (–) terminals of each battery.
Connect the jumper cables in the exact order (

shown in the illustration.

1

Connect a positive (red) jumper cable clamp to the positive (+)
terminal of the discharged battery.

2

Connect the clamp at the other end of the positive (red) cable
to the positive (+) terminal of the booster battery.

3

Connect a negative (black) cable clamp to the negative (–)
terminal of the booster battery.

4

Connect the clamp at the other end of the negative (black)
cable to a solid, stationary, unpainted metallic point (e.g.
engine hanger) away from the battery. Do not connect it to or
near any part that moves when the engine is cranked.

333

IN CASE OF AN EMERGENCY

CAUTION

When making the connections, to avoid serious injury, do no t
lean over the battery or accidentally let the jumper cables or
clamps touch anything except the correct battery terminals or
the ground.

5. Start your engine in the normal way . After starting, run it at about
2000 rpm for several minutes with the accelerator pedal lightly
depressed.

6. Carefully disconnect the cables in the exact reverse order: the
negative cable and then the positive cable.

7. Carefully dispose of the battery cover cloths which may now
contain sulfuric acid.

8. If removed, replace all the battery vent plugs.
If the cause of your battery discharging is not apparent (for example,

lights left on), you should have it checked.

IF YOUR VEHICLE OVERHEATS

If your engine coolant temperature gauge indicates
overheating, if you experience a loss of power, or if you hear a
loud knocking or pinging noise, the engine has probably
overheated.

334

When the engine overheats

Pull safely off the road, stop the vehicle and turn on your emergency
flashers. Put the transmission in ”P” and apply the parking brake.

A: If steam is coming from your engine:

Turn off the engine. Leave the hood closed until there is no sign of
steam or coolant. Your engine could have been seriously damaged
already. Call your Lexus dealer for assistance.

CAUTION

T o help avoid personal injury, keep the hood closed until there
is no steam. Escaping steam or coolant is sign of very high
pressure.

IN CASE OF AN EMERGENCY

335

IN CASE OF AN EMERGENCY

B: If no steam is coming from your engine:

Leave the engine running and turn off the air conditioning. Check
the following.

 Is the cooling fan operating?

acceptable range, turn off the engine and call your Lexus dealer.

If both conditions are O.K., after the engine coolant temperature has
cooled to normal, continue driving your vehicle.

If the engine coolant temperature does not cool down, or your
vehicle overheats again, have it checked as soon as possible by your
Lexus dealer.

336

IF YOU HAVE A FLAT TIRE

1. Reduce your speed gradually, keeping a straight line. Move
cautiously off the road to a safe place – well away from the traffic.
Avoid stopping on the center divider of a highway. Park on a level
spot with firm ground.

2. Stop the engine and turn on your emergency flashers.

3. Firmly set the parking brake and put the transmission in ”P”.

4. Have everyone get out of the vehicle on the side away from
traffic.

5. Read the following instructions thoroughly.

CAUTION

 Make sure to set the jack properly in the jack point.

Raising the vehicle with jack improperly positioned will
damage the vehicle or may allow the vehicle to fall off the
jack and cause personal injury.

 Never get under the vehicle when the vehicle is supported

by the jack alone.

 Use the jack only for lifting your vehicle during wheel

changing.

 Do not raise the vehicle with someone in the vehicle.
 When raising the vehicle, do not put an object on or under

the jack.

 Raise the vehicle only high enough to remove and change

the tire.

NOTICE

Do not continue driving with a deflated tire. Driving even a
short distance can damage a tire beyond repair.

1. Get the tool, jack and spare tire.

To prepare yourself for an emergency, you should familiarize
yourself with the use of the jack and each tool, and their storage
locations.

When storing the jack, put it into place and secure to prevent it from
flying forward during a collision or sudden braking.

To remove the spare tire:

1. Remove the spare tire carrier lid using a slotted screwdriver.

2. Insert the end of the jack handle extension into the lowering
screw and turn it counterclockwise with the handle, making sure the
handle remains firmly fitted onto the jack handle extension.

3. After the tire is lowered completely to the ground, remove the
holding bracket.

When storing the spare tire, put it in place with the outer side of the
wheel facing up. Then secure the tire, taking care that the tire goes
straight up without catching on any other part, to prevent it from
flying forward during a collision or sudden braking.

4. Loosen all the wheel nuts.

Always loosen the wheel nuts before raising the vehicle.
Turn the nuts counterclockwise to loosen them. To get maximum

leverage, fit the wrench to the nut so that the handle is on the right
side, as shown above. Grab the wrench near the end of the handle
and pull up on the handle. Be careful that the wrench does not slip
off the nut.

Do not remove the nuts yet – just unscrew them about one–half turn.

6. After making sure no one is in the vehicle, raise it high
enough so that the spare tire can be installed.

Allow for the fact that you need more ground clearance when
putting on the spare tire than when removing the flat tire.

To raise the vehicle, insert the jack handle extension into the jack
(it is a loose fit) and turn it clockwise with the handle, making sure
the handle remains firmly fitted onto the jack handle extension. As
the jack touches the vehicle and begins to lift, double–check that it
is properly positioned.

7. Remove the wheel nuts and remove the flat tire.

Lift the flat tire straight off and put it aside.
Roll the spare wheel into position and align the holes in the wheel

with the bolts. Then lift up the wheel and get at least the top bolt
started through its hole. Wiggle the tire and press it back over the
other bolts.

Before putting on the wheel, remove any corrosion on the mounting
surfaces with a wire brush or such. Installation of wheels without
good metal–to–metal contact at the mounting surface can cause
wheel nuts to loosen and eventually cause a wheel to come off while
driving. Therefore after the first 1600 km (1000 miles), check to see
that the wheel nuts are tight.
