CHECKING BATTERY CONDITION

Precautions

CAUTION

BATTERY PRECAUTIONS
The battery produces flammable and explosive

hydrogen gas.
 Do not cause a spark by contacting the battery

terminals with tools.
 Do not smoke or light a match near the battery.
The electrolyte contains poisonous and corrosive

sulfuric acid.

 Avoid contact with eyes, skin or clothes.
 Never inhale or swallow electrolyte.
 Wear protective safety glasses when working near

the battery.
 Keep children away from the battery.
EMERGENCY MEASURES
 If electrolyte gets in your eyes, flush your eyes with

clean water f o r a t l east 15 minutes and get immediate

medical attention. If possible, continue to apply

water with a sponge or cloth while traveling to the

medical office.

349

ELECTRICAL COMPONENTS

 If electrolyte gets on your skin, thoroughly wash the

contact area. If you feel a pain or burn, get medical
attention immediately.

 If electrolyte gets on your clothes, there is a

possibility of its soaking through to your skin, so
immediately take off the exposed clothing and follow
the procedure above, if necessary.

 If you accidentally swallow electrolyte, drink a large

quantity of water or milk. Follow with milk of
magnesia, beaten raw egg or vegetable oil. Then go
immediately for emergency help.

Terminals 2Hold–down clamp

Check the battery for corroded or loose connections,
cracks, or loose hold–down clamps.

1. If the battery is corroded, wash it off with a solution of warm
water and baking soda. Coat the terminals with grease to
prevent further corrosion.

2. If the connections are loose, tighten the clamp bolts –but do
not overtighten.

3. Tighten the hold–down clamp only enough to keep the
battery firmly in place. Overtightening may damage the battery
case.

350

ELECTRICAL COMPONENTS

NOTICE



Make sure the engine and all accessories are turned
off before performing maintenance.



When checking the battery, remove the ground cable
first and reinstall it last.



Be careful not to cause a short circuit with tools.



Take care no solution gets into the battery when
washing it.

BATTERY RECHARGING

PRECAUTIONS

During recharging, the battery is producing hydrogen
gas.

Therefore, before recharging:

1. If recharging with the battery installed on the vehicle, be
sure to disconnect the ground cable.

2. Make sure the power switch on the recharger is off when
connecting the charger cables to the battery and when
disconnecting them.

CAUTION

 Always charge the battery in an unconfined area. Do

not charge the battery in a garage or closed room

where there is not sufficient ventilation.
 Only do a slow charge (5 A or less). Charging at a

quicker rate is dangerous. The battery may explode

causing personal injuries.

1. Turn the ignition switch off and open the fuse box lid.

Determine which fuse may be causing the problem. The lid of
the fuse box shows the name of the circuit for each fuse.

64sa14

2. Make sur e t h e i noperative component is turned off. Pull
the suspected fuse straight out with the pull–out tool and
check it. If it has blown, push a new fuse into the clips.

64g008a



Good

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

b. Install only a fuse with the amperage rating designated on
the fuse box lid.

If you do not have a spare fuse, in an emergency you can pull
out the ”CIG”, ”RADIO NO.1”, ”DOME” or ”HTR” 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 to the amperage as possible. If the
amperage is lower than that specified, the fuse might blow out
again but this does not indicate anything wrong. Be sure to get
the correct fuse as soon as possible and return the substitute
to its original clips.



Blown

353

ELECTRICAL COMPONENTS

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

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

CAUTION

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

If the headlights or other electrical components do not
work and the blade type fuses are O.K., check the
cartridge type fuses. If any of the cartridge type fuses are
blown, they must be replaced.

If there is an overload in the circuits from the battery, the fuses
are designed to blow before the entire wiring harness is
damaged.

Always use a genuine Lexus fuse or equivalent for
replacement. Never install an ordinary wire – even for
a temporary fix. This may cause extensive damage and
possibly a fire.

ADDING WASHER FLUID

64sa01

If the washer tank becomes nearly empty, add washer
fluid.

You may use plain water as washer fluid. However, in cold
areas where temperatures range below the freezing point, use
washer fluid containing antifreeze. This product is available at
your Lexus dealer and most auto parts stores. Follow the
manufacturer’s directions for how much to mix with water.

NOTICE

Do not use engine antifreeze or any other substitute
because it may damage your vehicle’s paint.

REPLACING LIGHT BULBS

The illustrations on the following pages show the locations of
light bulbs. If it is necessary to replace a bulb, take your vehicle
to your Lexus dealer as soon as possible. Use bulbs with the
bulb numbers and wattage ratings given in the table.

CAUTION

 To prevent burning yourself, do not replace the light

bulbs while they are hot.

 Halogen bulbs have pressurized gas inside and

require special handling. They can burst or shatter if
scratched or dropped. Hold a bulb only by its plastic
or metal case. Do not touch the glass part of a bulb

with bare hands.
Vehicles with discharge headlights:
 Do not touch the high voltage socket when the head-

light turns on. 20000 V is momentarily generated and

may cause severe injury by electric shock.
 Do not disassemble, repair or take apart the headlight

bulbs, connector, power supply circuits and rotated

components. Or you may be injured by electric

shocks. Call your dealer when the headlights fail to

work or have to be replaced or disposed of.

The inside of the lens of exterior lights such as headlights may
temporarily fog up when the lens becomes wet in the rain or in
a car wash. This is not a problem because the fogging is
caused by the temperature difference between the outside and
inside of the lens, just like the windshield fogs up in the rain.
However, if there is a large drop of water on the inside of the
lens, or if there is water pooled inside the light, contact your
Lexus dealer.

NOTICE

Only use a bulb of the listed type.

BODY

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 do not dry quickly due to

lack of proper ventilation are exposed to high ambient

temperature.

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

Keep your vehicle clean by regular washing. In addition,

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

the ocean, you should hose off the undercarriage at least

once a month to minimize corrosion.

 High pressure water or steam is effective for cleaning the

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

these areas can cause corrosion.

 Wash the underside of the vehicle thoroughly when winter

is over.
See ”Washing and waxing” on page 366 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.

365

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.

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

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

WASHING AND WAXING

Washing your Lexus

Keep your vehicle clean by regular washing.

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

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

carcass of an insect

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

dust, iron dust or chemical substances

 When the vehicle becomes remarkably dirty with dust and

mud

366

BODY

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.

65sa01

Spray water on the side windows or top seals from above, at
a 45 angle to the ground.

NOTICE

Do not spray water at side windows and top seals in a
way which may cause water to enter the vehicle.

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.

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.

367

BODY

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 types of
brushes, unfiltered washing water, or the washing process
itself. Scratching reduces paint durability and gloss, especially
on darker colors. The manager of the car wash should be able
to advise you whether the process is safe for the paint on your
vehicle.

Waxing your Lexus

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

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

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

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

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

CLEANING THE INTERIOR

CAUTION

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

floor. This may prevent the SRS 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.

Leather–trimmed interior

The selected leather is used in your Lexus. Due to
characteristics of leather products, 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 off 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



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. T ry to keep your
upholstery always clean.



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



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



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

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.

CHECKING BRAKE FLUID

63sa06

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 cap by hand. Add brake fluid up to the
”MAX” line.

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

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

CAUTION

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

NOTICE

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

CHASSIS

63ca03



Type B

The recommended cold tire inflation pressure, tire
size and the combined weight of occupants and
cargo (vehicle capacity weight) are described on the
tire and loading information label.

You should check the tire inflation pressure every two
weeks, or at least once a month. And don’t forget the
spare, if so equipped. The inflation pressure for the
spare tire should be 420 kPa (4.3 kgf/cm
psi).

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

 The inflation pressure should be checked only

when the tires are cold. If your vehicle has been

parked for at least 3 hours and has not been driven for
more than 1.5 km or 1 mile since, you will get an

accurate cold tire inflation pressure reading.

 If you cannot adjust the tire inflation pressure

when the tires are cold, add 10 to 20 kPa more to the

front tires and rear tires than the cold tire inflation
pressure, but never exceed the maximum cold tire

inflation pressure molded on the tire sidewall.

 Always use a tire pressure gauge. The appearance

of the tire can be misleading. Besides, tire inflation
pressures that are even just a few pounds off can

degrade handling and ride.

 Do not bleed or reduce tire inflation pressure after

driving. It is normal for the tire inflation pressure to

be higher after driving.

If a gauge and air pump are not available, have your
vehicle checked by your Lexus dealer.

CAUTION

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

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

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

CAUTION

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

Low tire pressure (underinflation):

 Excessive wear

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: Tread wear 200 Traction AA Temperature
A

Tread wear – 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.

327

CHASSIS

Traction AA, A, B, C – The traction grades, from highest

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

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

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.

run–flat tire.

If you cannot distinguish between the standard tire and
run–flat tire, consult Lexus dealer.

A spare tire is not provided on the vehicle equipped with
run–flat tires. Confirm whether your vehicle is equipped
with a spare tire or not. If you have a flat tire, you have
to take a different action depending on whether the tires
are standard tires or run–flat tires.

Run–flat tires characteristics:

The vehicle with run–flat tires allows you to continue
driving for up to 160 km (100 miles) at the moderate
speed and do not ever exceed 90 km/h (55 mph) even
with a flat tire. After such usage, the tire must be
replaced. If you are not sure, consult your Lexus dealer .
If you have a flat tire, decrease the speed and drive at
lower speed to reduce the extent to which the tire is
damaged.

However, in some conditions (such as at high
temperatures), you could not continue driving for up to
160 km (100 miles).

The use of non–genuine wheels may prohibit optimum
performance.

The run–flat tires equipped on this vehicle are ones
dedicated for SC430. Do not use them on another
model.

Do not mix run–flat tires with standard tires.
The tire warranty book covers the detailed information

on run–flat tires. For details, see the tire warranty book.

Tire pressure warning system

The tire pressure warning system is equipped to warn
you of the low tire inflation pressure. For details, see
“Tire pressure warning system” on page 219.

TYPES OF TIRES

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

1. Summer tires

Summer tires are high–speed capability tires best suited
to highway driving under dry conditions.

Since summer tires do not have the same traction
performance as snow tires, summer tires are
inadequate for driving on snow–covered or icy roads.
For driving on snow–covered or icy roads, we
recommend using snow tires. If installing snow tires, be
sure to replace all four tires.

2. All season tires

All season tires are designed to provide better traction
in snow and to be adequate for driving in most winter
conditions, as well as for use all year round.

All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose
snow. Also, all season tires fall short in acceleration an d
handling performance compared with summer tires in
highway driving.

The details about how to distinguish summer tires from
all season tires are described on page 321.

CAUTION

 Do not mix summer and all season tires on your

vehicle as this can cause dangerous handling
characteristics, resulting in loss of control and
could cause death or serious injury.

 Do not use tires other than the manufacturer ’s

designated tires, and never mix tires or wheels
of the sizes different from the originals as this
could result in loss of control and could cause
death or serious injury.

333

CHASSIS

ROTATING TIRES

63sa07a

To equalize tire wear and help extend tire life, Lexus
recommends that you rotate your tires according to
the maintenance schedule. (For scheduled
maintenance information, please refer to the
“Owner’s Manual Supplement” or “Scheduled
Maintenance”.) 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 inflation 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.

Worn tread

Replace the tires when the tread wear indicators
show. The location of tread wear indicators is
shown by the “TWI” or “∆” marks, etc., molded on
the sidewall of each tire.

334

CHASSIS

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.

Your vehicle is equipped with P245/40R18 93V,
245/40ZR18 or 245/40ZR18 93Y tires: Your Lexus has

been fitted with specially developed tires which provide
exceptional dynamic performance under general road
conditions. However your riding comfort may worsen a
little and road noise may increase during driving. Riding
comfort and road noise with the run–flat tires may be a
little worse than that with the standard tires. You may
also notice that your tires will wear more rapidly and tire
grip performance will be reduced on the snowy and/or
icy roads when compared to high aspect ratio tires, etc.
Be sure to have snow tires or tire chains on the snowy
and/or icy roads and drive carefully with the speed
appropriate for road conditions.

NOTICE

Low profile tire like P245/40R18 93V, 245/40ZR18
or 245/40ZR18 93Y may have greater damage than
usual tires to its tire wheel when receiving impact
from the road surface. Therefore, pay attention to
the following.



Be sure to use with proper tire inflation
pressure. If the tire inflation pressure is low, the
tire may have greater damage. For detailed
information about tire inflation pressure, see
page 314 or 317.



Avoid driving onto high, sharp–edged objects
and other road hazards. Failure to do so can
lead to severe tire damage.

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

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.

335

CHASSIS

If air loss occurs while driving, do not continue driving.
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.

NOTICE



When you purchase new tires, consult your
Lexus dealer. If you change from run–flat tires
to standard tires, a spare tire should also be
purchased.



When the tires must be repaired or replaced,
have them repaired or replaced by Lexus dealer
or authorized dealer. The tire pressure sensors
will be affected by the installation or removal of
tires.



When the tires must be replaced, replace the
grommets for tire pressure sensors as well.

Tire selection

When replacing a tire, use a tire of the same size and
construction, and the same or greater maximum
load capacity as the originally installed tires.

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.

Check that the maximum load of the replaced tire is
greater than 1/2 of the Gross Axle Weight Ratings
(GAWR) of either the front axle or the rear axle,
whichever is greater. As for the maximum load of the
tire, see the load limit at maximum cold tire inflation
pressure mentioned on the sidewall of the tire, and as for
the Gross Axle Weight Ratings (GAWR), see the
Certification Label. For details about the Certification
Label and sidewall of the tire, see pages 288 and 321.

336

CHASSIS

CAUTION

Observe the following instructions. Otherwise, an
accident may occur resulting in death or serious
injuries.

 Do not mix radial, bias belted, or bias–ply tires

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

 Do not mix run–flat tires or standard tires on

your vehicle.

 Do not use tires other than the manufacturer ’s

recommended size, as this may 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 road, conventional or radial tires provide better
traction than snow or studded tires.

Snow tire selection

If you need snow tires, select tires of the same size,
construction and load capacity as the originally installed
tires.

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.

CAUTION

Observe the following instruction. Otherwise, an
accident may occur resulting in death or serious
injuries.

 Do not use snow tires other than the manufacturer’s

recommended size, as this may cause dangerous
handling characteristics resulting in loss of control.

337

CHASSIS

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.

CAUTION

 Do not drive with the snow tires incorrectly inflated.
 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 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.

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.

NOTICE



When the snow tires must be repaired or replaced,
have them repaired or replaced by Lexus dealer or
authorized tire dealer. The tire pressure sensor will
be affected by the installation or removal of snow
tires.



When the snow tires must be replaced, replace the
grommets for tire pressure sensors as well.



Do not attempt to use a tire chain on the compact
spare tire, as it may result in damage to the vehicle as
well as the tire.

INFORMATION

If the chains are installed, the tire pressure warning
system may not operate properly.

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.

338

CHASSIS

 When driving with chains installed, be sure to drive

carefully . Slow down before entering curves to avoid
losing control of the vehicle. Otherwise an accident
may occur.

REPLACING WHEELS

As you might have difficulty in identifying a flat or deflated
tire, a tire pressure warning system is provided on this
vehicle.

When replacing the wheels, be sure to install tire pressure
sensors on the wheels.

There are 2 ways to set up the tire pressure sensors.
a. Remove the sensor from the old wheel and install it to the

new wheel.
b. Use a new wheel and sensor.

You have to register an ID code for a new sensor. Up to 2
sets of codes can be registered. As one ID for the originally
installed sensor is registered at “MAIN” of the selector
switch, use the “2nd” position to register an ID for the new

sensor.

You do not need to re–register the ID code for any other
replacements. For the use of the originally installed tires,
put the selector switch at “MAIN” and for the use of tires
purchased later, put the switch at “2nd”. For the sensor

selector switch, see page 225.

CAUTION

 Have the tires, wheels or sensors replaced and ID

codes registered by Lexus dealer. If you need
sensors, purchase from Lexus dealer.

 The use of non–genuine wheels will cause the tire

pressure sensor to transmit the electronic code in
different manner, resulting in the failure of the
system.

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 a damaged wheel, the tire may slip off the
wheel or cause loss of handling control.

339

CHASSIS

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.

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.

CAUTION

Observe the following instruction. Otherwise, an
accident may occur resulting in death or serious
injuries.

 Do not use wheels other than the manufacturer’s

recommended size, as this may cause dangerous
handling characteristics resulting in loss of control.

ALUMINUM WHEEL PRECAUTIONS

 When installing aluminum wheels, check that the wheel

nuts are tight after driving your vehicle the first 1600 km

(1000 miles).

 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 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 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, occasionally, you may notice light knocking for a
short time whi l e a c c e l e r a t i n g o r d r i v i n g u p h ills. This is normal
and there is no need for concern.

Gasoline containing detergent additives

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

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

299

ENGINE

Quality gasoline

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

Cleaner burning gasoline

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

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

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.

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.

after the fuel pump shut off system activates, turn the ignition
switch to “ACC” or “LOCK” once and start it.

CAUTION

Inspect the ground under the vehicle before restarting
the engine. If you find that liquid has leaked onto the

ENGINE

FACTS ABOUT ENGINE OIL

CONSUMPTION

Functions of engine oil

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

Engine oil consumption

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

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

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

combustion process.

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

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

lubricate the exhaust valve stems.

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

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

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

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

0.9 lmp·qt./600 miles).

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

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

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

302

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” on page 304.

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.

303

ENGINE

CHECKING THE ENGINE OIL LEVEL

61sa04a

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

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

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

3. 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.



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 the coolant. (For the coolant type, see
“Coolant type selection” described below.)

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.

307

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 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.

Coolant type selection

Use of improper coolants may damage your engine cooling
system.

Only use ”Toyota Super Long Life Coolant” or similar high
quality ethylene glycol based non–silicate, non–amine,
non–nitrite, and non–borate coolant with long–life hybrid
organic acid technology. (Coolant with long–life hybrid organic
acid technology is a combination of low phosphates and
organic acids.)

For the U.S.A.—“T oyota Super Long Life Coolant” is a mixture
of 50% coolant and 50% deionized water. This coolant
provides protection down to about –35C (–31F)

For Canada—“Toyota Super Long Life Coolant” is a mixture of
55% coolant and 45% deionized water. This coolant provides
protection down to about –42C (–44F).

NOTICE

Do not use plain water alone.

Lexus recommends “Toyota Super Long Life Coolant”, which
has been tested to ensure that it will not cause corrosion nor
result in malfunction of your engine coolant system with proper

DO–IT–YOURSELF SERVICE

PRECAUTIONS

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

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

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

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

For information on tools and parts for do–it–yourself
maintenance, see ”Parts and tools” on page 293.

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

CAUTION

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

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

 Right after driving, the engine compartment – the

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

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

paper or rags, in the engine compartment.

 Do not smoke, cause sparks or allow open flames

near fuel or the battery. Their fumes are flammable.

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

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

 Be sure the ignition is off if you work near the electric

cooling fan o r radiator grille. With the ignition on, the
electric cooling fan may automatically start to run if
the air conditioning is on and/or if the coolant
temperature is high.

 Use eye protection whenever you work on or under

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

 Be extremely cautious when working on the battery.

It contains poisonous and corrosive sulfuric acid.

MAINTENANCE

MAINTENANCE REQUIREMENTS

Your Lexus vehicle has been designed for 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 / Scheduled Maintenance” are those
required to be serviced at regular intervals.

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

It is recommended that only 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.

280

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. 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.

MAINTENANCE

DOES YOUR VEHICLE NEED

REPAIRING?

Be on the alert for changes in performance and sounds, and
visual tip–offs that indicate service is needed. Some important
clues are:

 Engine missing, stumbling, or pinging
 Appreciable loss of power
 Strange engine noises
 A fluid leak under the vehicle (However, water dripping from

the air conditioning after use is normal.)

 Change in exhaust sound (This may indicate a dangerous

carbon monoxide leak. Drive with the windows open and

have the exhaust system checked immediately.)

 Flat–looking tires, excessive tire squeal when cornering,

uneven tire wear

 Vehicle pulls to one side when driving straight on a level

road

 Strange noises related to suspension movement
 Loss of brake effectiveness, spongy feeling brake pedal,

pedal almost touches floors, vehicle pulls to one side when

braking

 Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to your Lexus

dealer as soon as possible. It probably needs adjustment or
repair.

CAUTION

Do not continue driving with the vehicle unchecked. It
could result in serious vehicle damage and possibly
personal injury.

284

EMISSION INSPECTION AND

MAINTENANCE (I/M) PROGRAMS

Some states have vehicle emission inspection programs
which include OBD (On–Board Diagnostics) checks.

The OBD system monitors the operation of the emission
control system. When the OBD system determines that a
problem exist s somewhere in the emission control system, the
malfunction indicator lamp comes on. In this case, your vehicle
may not pass the I/M test and need to be repaired. Contact
your Lexus dealer to service the vehicle.

Even if the malfunction indicator lamp does not come on, your
vehicle may not pass the I/M test as readiness codes have not
been set in the OBD system.

Readiness codes are automatically set during ordinary driving.
However, when the battery is disconnected or run down, the
codes are erased. Also, depending on your driving habits, the
codes may not be completely set.

Also, if the malfunction indicator lamp had come on recently
due to temporary malfunction such as a loose fuel tank cap,
your vehicle may not pass the I/M test.

The malfunction indicator lamp will go off after taking several
driving trips, but the error code in the OBD system will not be
cleared unless about 40 trips or more are taken.

If your vehicle does not pass the I/M test and the malfunction
indicator lamp does not come on, contact your Lexus dealer to
prepare the vehicle for re–testing.

DRIVING TIPS

BREAK–IN PERIOD

Drive gently and avoid high speeds.

Y ou need not follow a break–in schedule with your new Lexus.
But following a few simple tips for the first 1600 km (1000 miles)
can add to the future economy and long life of your vehicle:

 Avoid full throttle acceleration when starting and driving.
 Avoid racing the engine.
 Try to avoid hard stops during the first 300 km (200 miles).
 Do not drive for a long time at any single speed, either fast

or slow.

OPERATION IN FOREIGN

COUNTRIES

If you plan to drive your Lexus in another country ...
First, comply with the vehicle registration laws.
Second, confirm the availability of the correct fuel (unleaded

and minimum octane rating).

TIPS FOR DRIVING IN VARIOUS

CONDITIONS

 Always slow down in gusty crosswinds. This will allow you

much better control.

 Drive slowly onto curbs and, if possible, at a right angle.

Avoid driving onto high, sharp–edged objects and other
road hazards. Failure to do so can lead to severe tire

damage such as a tire burst.
Drive slowly when passing over bumps or travelling on a
bumpy road. Otherwise, the impact could cause severe

damage to the tires and/or wheels.

 When parking on a hill, turn the front wheels until they touch

the curb so that the vehicle will not roll. Apply the parking
brake, and place the transmission in ”P”. If necessary , block

the wheels.

 Washing your vehicle or driving through deep water may get

the brakes wet. To see whether they are wet, check that
there is no traffic near you and then press the pedal lightly.
If you do not feel a normal braking force, the brakes are
probably wet. T o dry them, drive the vehicle cautiously while
lightly pressing the brake pedal with the parking brake
applied. If they still do not work safely, pull to the side of the

road and call a Lexus dealer for assistance.

228

DRIVING TIPS

CAUTION

 Before driving off, make sure the parking brake is

fully released and that the parking brake reminder
light is off.

 Do not leave your vehicle unattended while the

engine is running.

 Do not rest your foot on the brake pedal while driving.

It can cause dangerous overheating, needless wear,
and poor fuel economy.

 To drive down a long or steep hill, reduce your speed

and downshift. Remember, if you ride the brakes
excessively, they may overheat and not work
properly. See page 204.

 Be careful when accelerating, upshifting,

downshifting or braking on a slippery surface. The
abrupt change in engine speed, such as sudden
acceleration or engine braking, could cause the
vehicle to skid or spin.

 Do not drive in excess of the speed limit. Even if the

legal speed limit permits it, do not drive over 140 km/h
(85 mph) unless your vehicle has high–speed
capability tires. Driving over 140 km/h (85 mph) may
result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine
whether the tires on your vehicle are high–speed
capability tires or not before driving at such speeds.

 Do not continue normal driving when the brakes are

wet. If they are wet, your vehicle will require a longer
stopping distance, and it may pull to one side when
the brakes are applied. Also, the parking brake will
not hold the vehicle securely.

WINTER DRIVING TIPS

Make sure your coolant is properly protected against
freezing.

Only use ”Toyota Super Long Life Coolant” or similar high
quality ethylene glycol based non–silicate, non–amine,
non–nitrite, and non–borate coolant with long–life hybrid
organic acid technology (Coolant with long–life hybrid organic
acid technology is a combination of low phosphates and
organic acids.)

See “Checking the engine coolant level” on page 307 for
details of coolant type selection.

For the U.S.A.—“T oyota Super Long Life Coolant” is a mixture
of 50% coolant and 50% deionized water. This coolant
provides protection down to about –35C (–31F).

For Canada—“Toyota Super Long Life Coolant” is a mixture of
55% coolant and 45% deionized water. This coolant provides
protection down to about –42C (–44F).

NOTICE

Do not use plain water alone.

229

DRIVING TIPS

Check the condition of the battery and cables.

Cold temperatures reduce the capacity of any battery, so it
must be in top shape to provide enough power for winter
starting. Page 349 tells you how to visually inspect the battery.
Y our Lexus dealer and most service stations will be pleased to
check the battery charge level.

Make sure the engine oil viscosity is suitable for the cold
weather.

See page 306 for recommended viscosity. Leaving a heavy
summer oil in your vehicle during winter months may cause
harder starting. If you are not sure about which oil to use, call
your Lexus dealer – they will be pleased to help.

Check the electronic ignition system for loose
connections or obvious damage.

Keep the door locks from freezing.

Squirt lock de–icer or glycerine into the locks to keep them from
freezing.

Use a washer fluid containing an antifreeze solution.

This product is available at your Lexus dealer and most auto
parts stores. Follow the manufacturer’s directions for how
much to mix with water.

NOTICE

Do not use engine antifreeze or any other substitute
because it may damage your vehicle’s paint.

Do not use your parking brake when there is a possibility
it could freeze.

When parking, put the transmission into ”P” and block the f ron t
wheels. Do not use the parking brake, or snow or water
accumulated in and around the parking brake mechanism may
freeze the parking brake, making it hard to release.

Keep ice and snow from accumulating under the fenders.

Ice and snow built up under your fenders can make steering
difficult. During bad winter driving, stop and check under the
fenders occasionally.

Depending on where you are driving, we recommend you
carry some emergency equipment.

Some of the things you might put in the vehicle are tire chains,
window scraper, bag of sand or salt, flares, small shovel,
jumper cables, etc.

HOW TO SAVE FUEL AND MAKE

YOUR VEHICLE LAST LONGER

Improving fuel economy is easy – just take it easy . It will help
make your vehicle last longer, too. Here are some specific tips
on how to save money on both fuel and repairs:

 Keep your tires inflated at the correct pressure. Check

the pressure every two weeks, or at least once a month.

Underinflation causes tire wear and wastes fuel.

 Do not carry unneeded weight in your vehicle. Excess

weight puts a heavier load on the engine, causing greater

fuel consumption.

 Avoid lengthy warm–up idling. Once the engine is

running smoothly, begin driving – but gently. Remember,
however, that on cold winter days this may take a little

longer.

 Accelerate slowly and smoothly . A void jackrabbit starts.
 Avoid long engine idling. If you have a long wait and you

are not in traffic, it is better to turn off the engine and start

again later.

 Avoid engine over–revving. Use a gear position suitable

for the road on which you are traveling.

 Avoid continuous speeding up and slowing down.

Stop–and–go driving wastes fuel.

 Avoid unnecessary stopping and braking. Maintain a

steady pace. Try to time the traffic signals so you only need
to stop as little as possible or take advantage of through
streets to avoid traffic lights. Keep a proper distance from
other vehicles to avoid sudden braking. This will also

reduce wear on your brakes.

 Avoid heavy traffic or traffic jams whenever possible.
 Do not rest your foot on the brake pedal. This causes

premature wear, overheating and poor fuel economy.

 Maintain a moderate speed on highways. The faster you

drive, the greater the fuel consumption. By reducing your

speed, you will cut down on fuel consumption.

 Keep the front wheels in proper alignment. Avoid hitting

the curb and slow down on rough roads. Improper
alignment not only causes faster tire wear but also puts an

extra load on the engine, which, in turn, wastes fuel.

 Keep the bottom of your vehicle free from mud, etc.

This not only lessens weight but also helps prevent

corrosion.
