DRIVING TIPS
270
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 ºToyota Super Long Life Coolantº or similar high
quality ethylene glycol based non-silicate, non-amine,
non-nitrite, and non-borate coolant with long-life hybrid
organic acid technology.
See ºChecking the engine coolant levelº on page 337 for
details of coolant type selection.
ºToyota Super Long Life Coolantº is pre-mixed with 50%
coolant and 50% deionized water. This coolant provides
protection down to about -35 C (-31F).
NOTICE
Do not use plain water alone.
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 378 tells you how to visually inspect the battery.
Your 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.

MAINTENANCE
309
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 ºOwner's Guideº, ºOwner's Manual
Supplementº or ºWarranty Bookletº for the details.
GENERAL MAINTENANCE
Listed below are the general maintenance items that should be
performed at the intervals specified. It is recommended that
any problem you notice be brought to the attention of your
Lexus dealer or qualified service shop for their advice.
CAUTION
Make these checks only with adequate ventilation if you
run the engine.
Engine compartment
Items listed below should be checked from time to time,
e.g. each time when refueling.
Washer fluid
Make sure there is sufficient fluid in the tank. See page 384 for
additional information.
Engine coolant level
Make sure the coolant level is between the Upper and Lower
lines on the see-through reservoir when the engine is cold.
See page 337 for additional information.
Battery
Your Lexus has a maintenance free battery. You do not have
to add distilled water. For longer life of the battery, however,
see page 378 for additional information.

MAINTENANCE
312
DOES YOUR VEHICLE NEEDREPAIRING?
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.

Remember that battery and ignition cables carry high
currents or voltages. Be careful of accidentally causing a short circuit.

Do not overfill automatic transmission fluid, or thetransmission could be damaged.

Be careful not to scratch the glass surface with thewiper frame.
