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 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.
490
ENGINE
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 W orld–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.
491
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.
492
ENGINE
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.
493
ENGINE
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” described below.
USED ENGINE OIL
494
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.

CHECKING THE ENGINE OIL
LEVEL
62X001e
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 o n 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.

Remove the oil filler cap and add engine oil a little at a
time, checking the dipstick. The approximate quantity o f
oil needed to fill between the low line and the full line on
the dipstick is indicated below for reference.
When the level reaches within the correct range, return
the filler cap and turn the cap clockwise until you hear a
click.

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.

Either or both API registered marks are added to some
oil containers to help you select the oil you should use.
The API Service Symbol is located anywhere on the
outside of the container.
The top portion of the label shows the oil quality by
API (American Petroleum Institute) designation such
as SJ. The center portion of the label shows the SAE
viscosity grade such as SAE 5W–30.
”Energy–Conserving”, shown in the lower portion,
indicates that the oil has fuel–saving capabilities.

Radiator 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.
501
ENGINE
CAUTION
To prevent burning yourself, do not remove the radiator
cap when the engine is hot.
502
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 489.
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.

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.
563
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 565 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.
564
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.
565
BODY
Plastic wheel ornaments: The plastic wheel
ornaments are damaged easily by organic substances.
If any organic substance splashes an ornament, be sure
to wash it off with water and check if the ornament is
damaged.
CAUTION
Do not attach the heavily damaged plastic wheel
ornament. It may fly off the wheel and cause accidents
while the vehicle is moving.
566
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 organic substances (gasoline,
kerosene, benzine 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.
567
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.
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.
3. Wax the vehicle again when water does not bead but
remains on the surface in large patches.
CLEANING THE INTERIOR
568
BODY
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.
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.
