CHECKING BRAKE FLUID

63R001b

To check the fluid level, simply look at the
see–through reservoir. T h e 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. So be sure to keep the reservoir
filled.

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.

Remove and replace the reservoir cap by hand. Add
brake fluid up to the ”MAX” line.

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.

446

CAUTION

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

CHASSIS

NOTICE

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

for 20 minutes (a little more in frigid temperatures), the
fluid is hot (60C – 80C or 140F – 175F). You 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 PRESSURE

63R004a

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

Y ou should check the tire pressures every two weeks, or
at least once a month. And don’t forget the spare! The
air pressure for the spare tire should be 210 kPa (2.1

2

or bar, 30 psi). Incorrect tire pressure can

kgf/cm
reduce tire life and make your vehicle less safe to drive.

452

Low tire pressure results in excessive wear, poor
handling, reduced fuel economy, and the possibility of
blowouts from overheated tires. Also, low 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.

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

CHASSIS

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 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.

63E005–1

ROTATING TIRES

453

CHASSIS

To equalize tire wear and help extend tire life, Lexus
recommends that you rotate your tires
approximately every 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 alignment, out–of balance
wheels, or severe braking.

Before storing radial, snow or studded tires, mark the
direction of rotation and be sure to install them in the
same direction when using them again. Tires should be
stored in a cool dry place.

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. If you 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. 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

456

CHASSIS

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.

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 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.

457

CHASSIS

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.

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 front 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.

458

CAUTION

 Snow tires should be inflated to the same pressure as

the original tires.

 Never drive over 120 km/h (75 mph) with any type of

snow tires.

CHASSIS

NOTICE

461

CHASSIS

If the wrong combination of tire and chain is used,
the chains could damage the vehicle body.

Chain installation

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

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.

462

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, the tire may slip
off the wheel or 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.

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.

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.

497

BODY

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 w a te r o r s t ea m i s e ffective 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” on page 499 for more tips.

Check the co n d ition 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.

Check the inte r i o r o f 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.

498

BODY

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 is 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 f r o m t h e 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.

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.

499

BODY

CAUTION

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

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 organic substances (gasoline,
kerosene, benzine or strong solvents), which may
be toxic or cause damage.

500

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.

BODY

Waxing your Lexus

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

Once a month or if the vehicle surface 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.

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

CAUTION

 Be careful not to splash water or spill liquid on the

floor. This may prevent the side airbags from
activating correctly, resulting in serious injury.

 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.

CLEANING THE INTERIOR

501

BODY

Leather Interior

The selected leather is used in your Lexus. Due to a
leather product, some parts of leather may be rough,
uneven or scratched originally.

To keep good appearance, we recommend you to clean
it periodically twice a year.

Remove dirt on the leather in the following ways:

1. Wipe it off lightly using a soft cloth (e.g. gauze)
dampened with 5% solution of neutral detergent for
wool.

2. Wring water from a clean cloth and thoroughly wipe
off all traces of detergent with it.

3. Wipe of f the surface of the leather with a dry soft cloth.
Allow the leather to dry in a ventilated shaded area.
Excess of wet may cause the hardening or shrinking of
the leather.

Dirt or sand adhered to the leather may damage
the treated surface and cause it to wear earlier.
Remove dirt or sand using a vacuum cleaner.



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 (Dash)

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.

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. T o 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

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 ”RAD NO.1”, ”RADIO NO.2” or ”PWR
OUTLET” 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.

FUEL

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.

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/warm up 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 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 Rating or Research
Octane Number lower than stated above will cause
persistent heavy knocking. If it is severe, this will lead
to engine damage.

425

ENGINE

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.

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 three 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.

Oxygenates in gasoline

Lexus allows the use of oxygenate blended gasoline
where the oxygenate content is up to 10% ethanol or
15% MTBE. If you 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.

Sulfur in gasoline

If your vehicle is certified to California Emission
Regulation, the vehicle is designed to operate on
California cleaner burning gasoline (CBG) that
contains lower sulfur. If you cannot use California
CBG, your emission control system may suffer
damage and turn on the Malfunction Indicator Lamp.

If the malfunction is caused by the type of fuel used,
repairs may not be covered by your warranty.

426

ENGINE

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.

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.

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

427

ENGINE

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.

428

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 under driving conditions such as
high speeds 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.

ENGINE

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 431.

429

ENGINE

USED ENGINE OIL

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.

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

430

CHECKING THE ENGINE OIL

LEVEL

62R001c

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. Reinsert the dipstick 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.

434

Engine oil selection

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

Recommended viscosity (SAE):

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.

CHECKING THE ENGINE

COOLANT LEVEL



Reservoir cap 2Upper line 3Lower line

Look at the see–through coolant reservoir when the
engine is cold. The coolant level is satisfactory if it
is between the”FULL” and ”LOW” lines on the
reservoir. If the level is low, add ethylene–glycol
type coolant for a proper corrosion protection of
aluminum components.

The coolant level in the reservoir will vary with engine
temperature. However, if the level is on or below the
”LOW” line, add coolant. Bring the level up to the ”FULL”
line.

Always use ethylene–glycol type coolant for a proper
corrosion protection of aluminum components. See
information in the next column.

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, engine coolant filler cap,
radiator cap and 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.

437

ENGINE

CAUTION

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

438

ENGINE

Coolant type selection

Use of improper coolants may damage your engine
cooling system. Your coolant must contain
ethylene–glycol type coolant for a proper corrosion
protection of your engine that contains aluminum
components. Use ”Toyota Long Life Coolant” or
equivalent.

In addition to preventing freezing and subsequent
damage to the engine, this type of coolant will also
prevent corrosion. Further supplemental inhibitors or
additives are neither needed nor recommended.

Read the coolant container for information on freeze
protection. Follow the manufacturer’s directions for how
much to mix with plain water (preferably demineralized
water or distilled water). The total capacity of the cooling
system is given on page 423.

We recommend to use 50% solution for your Lexus, to
provide protection down to about –35C (–31F). When
it is extremely cold, to provide protection down to about
–50C (–58F), 60% solution is recommended. Do not
use more than 70% solution for better coolant
performance.

NOTICE

Do not use alcohol type antifreeze or plain water
alone.

SPARK PLUGS

62R031c

439

ENGINE

Your engine is fitted with iridium–tipped spark
plugs.

NOTICE

Use only iridium–tipped spark plugs and do not
adjust gaps for your engine performance and
smooth drivability.

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
“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.

405

MAINTENANCE

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

It is recommended that any genuine Lexus parts be
used for maintenance.

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.

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 “Owner’s Guide”, “Owner’s
Manual Supplement” or “Warranty Booklet” for the
details.
