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 ªOwner's Guideº, ªOwner's Manual
Supplementº or ªWarranty 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

lines on the see±through reservoir when the engine is cold.
See page 337 for additional information.

Your Lexus has a maintenance free battery. You do not have
to add distilled water. For longer life of the battery, however,

BODY
397
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
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.
