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.
444
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 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 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.
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.
445
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.
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.
446
BODY
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.
3. Wax the vehicle again when water does not bead but
remains on the surface in large patches.
CLEANING THE INTERIOR
447
BODY
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.
448
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.
NOTICE
449
BODY
450
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
BODY
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.
Do not use the belts until they become dry.
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 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.

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”, ”RAD 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.

To check the fluid level, simply look at the
see–through reservoir . T he 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 cover 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.
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.

or bar, 32 psi). Incorrect tire pressure can
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 press u r e s a t t h e p r oper 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
397
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
398
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.

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.
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
401
CHASSIS
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 grade of 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.
402
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.
403
CHASSIS
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.
Tire chain selection
Regulations regarding the use of tire chains vary
according to location or type of road. Always check
the local regulations before installing chains.
Use SAE Class ”S” type radial tire chains, with the
exception of radial cable chains or V–bar type chains.
404
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.
CHASSIS
405
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.
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.

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 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.
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.
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
373
ENGINE
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.
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.
374
ENGINE
Gasolines 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 that 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
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.
375
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 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.
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 378.
376
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.

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.

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.
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
cap pressure and check for leaks in the cooling system.
384
CAUTION
To prevent burning yourself, do not remove the radiator
cap when the engine is hot.

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 371.
We recommend to use 50% solution for your Lexus, to
provide protection down to about –35C (–31F). When
it is extremely cold, to provide protection down to about
–50C (–58F), 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
62R031a
Your engine is fitted with iridium–tipped spark
plugs.
NOTICE
Use only iridium–tipped spark plugs for your
engine performance and smooth drivability.

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
control 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.
351
MAINTENANCE
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 your Owner’s Guide, Owner’s
Manual Supplement or Warranty Booklet for the details.
