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 303.
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 smoke, cause sparks or allow open flames
around 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 or 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.
Warning: Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.

2003 IS300 from Aug. ’02 Prod. (OM53439U)
INTRODUCTION
NOTICE
Remember that battery and ignition cables carry high
currents or voltages. Be careful of accidentally
causing a short circuit.
Before closing the engine hood, check to see that you
have not forgotten any tools, rags, etc.
Do not drive with the air cleaner removed, or
excessive engine wear could result. Also backfiring
could cause a fire in the engine compartment.
Do not overfill automatic transmission fluid, or the
transmission could be damaged.
Be careful not to scratch the glass surface with the

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.

2003 IS300 from Aug. ’02 Prod. (OM53439U)
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 ”Owner’s Guide”, ”Owner’s Manual
Supplement” or ”Warranty Booklet” for the details.

295
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.
296
2003 IS300 from Aug. ’02 Prod. (OM53439U)
EMISSIONS 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 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 as readiness codes
have not been set, 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 slowly with the manual transmission in a high
gear.
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).
258
2003 IS300 from Aug. ’02 Prod. (OM53439U)
DRIVING TIPS
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 resulting in tire bursts.
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” (automatic) or in
first or reverse (manual). 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. To 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.
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 235.
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 spin or skid.
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.
2003 IS300 from Aug. ’02 Prod. (OM53439U)
259
DRIVING TIPS
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.
260
WINTER DRIVING TIPS
Make sure you have a proper freeze protection of engine
coolant.
Your coolant must contain ethylene–glycol type coolant for a
proper corrosion protection of aluminum components. Use
”Toyota Genuine Long Life Coolant” or equivalent. See
”Checking the engine coolant level” on page 319 for
instructions.
NOTICE
Do not use alcohol type antifreeze or plain water alone.
When it is extremely cold, we recommend to use 60% solution
for your Lexus, to provide protection down to about –50C
(–58F). Do not use more than 70% solution for better coolant
performance.
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 348 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 317 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.
2003 IS300 from Aug. ’02 Prod. (OM53439U)
DRIVING TIPS
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” (automatic) or into
first or reverse (manual) and block the front 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.

DRIVING TIPS
DINGHY TOWING
SV32002
Your vehicle is not designed to be dinghy towed (with four
wheels on the ground) behind a motorhome.
NOTICE
Do not tow your vehicle with four wheels on the ground.
This may cause serious damage to your vehicle.
TRAILER TOWING

DRIVING TIPS
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 . Avoid 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.
2003 IS300 from Aug. ’02 Prod. (OM53439U)
263
DRIVING TIPS
Keep your vehicle tuned–up and in top shape. A dirty air
cleaner, improper valve clearance, dirty plugs, dirty oil and
grease, brakes not adjusted, etc. all lower engine
performance and contribute to poor fuel economy. For
longer life of all parts and lower operating costs, keep all
maintenance work on schedule, and if you often drive under
severe conditions, see that your vehicle receives more
frequent maintenance. (For scheduled maintenance
information, please refer to the ”Owner’s Manual
Supplement / Scheduled Maintenance”.)
CAUTION
Never turn off the engine to coast down hills. Your
power steering and brake booster will not function
without the engine running. Also, the emission control
system operates properly only when the engine is
running.

IN CASE OF AN EMERGENCY
IF YOUR ENGINE STALLS WHILE
DRIVING
If your engine stalls while driving . . . .
1. Reduce your speed gradually, keeping a straight line.
Move cautiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see ”If your vehicle will not start”.
CAUTION
If the engine is not running, the power assist for the
brakes and steering will not work, so steering and
braking will be much harder than usual.
IF YOU CANNOT INCREASE THE
ENGINE SPEED
If the engine speed does not increase with the accelerator
pedal depressed down to about the middle position, there
may be a problem somewhere in your electronic throttle
control system.
At this time, if you depress the accelerator pedal more firmly
and slowly, you can drive you vehicle at low speeds. Have your
vehicle checked by your Lexus dealer as soon as possible.
Even if the a b n o r m a lity of the electronic throttle control system
is corrected during low speed driving, the system may not be
recovered until the engine is stopped and the ignition key is
turned to ”ACC” or ”LOCK” position.
CAUTION
Be especially careful to prevent erroneous pedal
operation.

IN CASE OF AN EMERGENCY
IF YOUR VEHICLE WILL NOT
START
(a) Simple checks
Before making these checks, make sure you have followed the
correct starting procedure instructions in ”How to start the
engine” on page 229 and that you have sufficient fuel. Since
your vehicle is equipped with the engine immobiliser system,
also check whether the other keys will start the engine. If they
work, your key may be broken. Have the key checked at your
Lexus dealer. If none of your keys work, the system is possibly
broken. Call your Lexus dealer. See ”Keys” on page 8.
If the engine is not turning over or is turning over too
slowly –
1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is
cranked, the battery is discharged. You may try jump starting.
See ”(c) Jump starting” for further instruction.
If the light is O.K., but the engine still will not start, it needs
adjustment or repair. Call a Lexus dealer, Roadside
Assistance or Customer Service Assistance. (See
”Foreword”.)
NOTICE
Do not pull– or push–start the vehicle. It may damage
the vehicle or cause a collision when the engine starts.
Also the three–way catalytic converter may overheat
and become a fire hazard.
If the engine turns over at its normal speed but will not
start –
1. The engine may be flooded because of repeated cranking.
See ”(b) Starting a flooded engine” for further instructions.
2. If the engine still will not start, it needs adjustment or repair.
Call a Lexus dealer, Roadside Assistance or Customer
Service Assistance. (See ”Foreword”.)

IN CASE OF AN EMERGENCY
(b) Starting a flooded engine
If the engine will not start, your engine may be flooded
because of repeated cranking.
If this happens, turn the key to ”START” with the accelerator
pedal held down. Continue this operation for 30 seconds and
then stop cranking. Then try starting the engine with your foot
off the accelerator pedal.
If the engine does not start after 30 seconds of cranking,
release the key, wait a few minutes and try again.
If the engine still will not start, it needs adjustment or repair.
Call a Lexus dealer, Roadside Assistance or Customer
Service Assistance. (See ”Foreword”.)
NOTICE
Do not crank for more than 30 seconds at a time. This
may overheat the starter and wiring systems.
(c) Jump starting
To avoid serious personal injury and damage to your
vehicle which might result from battery explosion, acid
burns, electrical burns, or damaged electronic
components, these instructions must be followed
precisely.
If you are unsure about how to follow this procedure, we
strongly recommend that you seek help from your Lexus
dealer, Roadside Assistance or Customer Service Assistance.
(See ”Foreword”.)
CAUTION
Batteries contain sulfuric acid which is poisonous
and corrosive. Wear protective safety glasses when
jump starting, and avoid spilling acid on your skin,
clothing, or vehicle.
If you should accidentally get acid on yourself or in
your eyes, remove any contaminated clothing and
flush the affected area with water immediately . Then
get immediate medical attention. If possible,
continue to apply water with a sponge or cloth while
en route to the medical office.
The gas normally produced by a battery will explode
if a flame or spark is brought near. Use only
standardized jumper cables and do not smoke or
light a match while jump starting.

Warning: Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
NOTICE
The battery used for boosting must be 12 V. Do not jump
start unless you are sure that the booster battery is
correct.

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

IN CASE OF AN EMERGENCY
2. If required, remove all the vent plugs from the booster
battery . Lay a cloth over the open vents on the booster battery.
(This helps reduce the explosion hazard, personal injuries and
burns.)
If the booster battery is an extended maintenance interval
battery, it is not necessary to remove the vent plugs.
3. If the engine in the vehicle with the booster battery is not
running, start it and let it run for about 5 minutes. During jump
starting, run the engine at about 2000 rpm with the accelerator
pedal lightly depressed.
4. Locate positive (+) and negative (–) terminals of each
battery . C o n n ect the jumper cables in the exact order (
3 4
) shown in the illustration.
1
Connect a positive (red) jumper cable clamp to the
1 2
positive (+) terminal of the discharged battery.
2
Connect the clamp at the other end of the positive (red)
cable to the positive (+) terminal of the booster battery.
3
Connect a negative (black) cable clamp to the negative
(–) terminal of the booster battery.
4
Connect the clamp at the other end of the negative (black)
cable to a solid, stationary, unpainted metallic point (such
as shown in the illustration) away from the battery. Do not
connect it to o r near any part that moves when the engine
is cranked.
CAUTION
When making the connections, to avoid serious injury,
do not lean over the battery or accidentally let the
jumper cables or clamps touch anything except the
correct battery terminals or the ground.
5. Start your engine in the normal way . After starting, run it at
about 2000 rpm for several minutes with the accelerator pedal
lightly depressed.
6. Carefully disconnect the cables in the exact reverse order:
the negative cable and then the positive cable.
7. Carefully dispose of the battery cover cloths which may
now contain sulfuric acid.
8. If removed, replace all the battery vent plugs.
If the cause of your battery discharging is not apparent (for
example, lights left on), you should have it checked at your
Lexus dealer.
