Self-restoring coat

The vehicle body has a self-restoring coat-

ing that is resistant to small surface

scratches caused in a car wash, etc.

The coating lasts for 5 to 8 years from

when the vehicle is delivered from the

plant.

The restoration time differs depending on

the depth of the scratch and outside tem-

perature. The restoration time may

become shorter when the coating is

warmed by applying warm water.

Deep scratches caused by keys, coins,

etc., cannot be restored.

Do not use wax that contain abrasives.

Automatic car washes

Before washing the vehicle:

• Fold the mirrors

• Turn off the power back door (if

equipped)

Start washing from the front of the vehicle.
Extend the mirrors before driving.

Brushes used in automatic car washes

may scratch the vehicle surface, parts

(wheel, etc.) and harm your vehicle’s

paint.

Rear spoiler may not be washable in

some automatic car washes. There may

also be an increased risk of damage to

vehicle.

What about do-it-yourself mainte-
nance?

Many maintenance items are easy to do
yourself if you have a little mechanical abil-
ity and a few basic automotive tools.
Note, however, that some maintenance
tasks require special tools and skills. These
are best performed by qualified techni-
cians. Even if you’re an experienced do-it-
yourself mechanic, we recommend that
repairs and maintenance be conducted by
any authorized Lexus retailer or Lexus
authorized repairer, or any reliable
repairer. Any authorized Lexus retailer or
repairer will keep a record of maintenance,
which could be useful should you ever
require Warranty Service. Should you
choose to select a qualified and equipped
professional other than an authorized
Lexus repairer to service or maintain your
vehicle, we recommend that you request
that a record of maintenance be kept.

Does your vehicle need repairs?

Be on the alert for changes in performance

and sounds, and visual tip-offs that indicate

service is needed. Some important clues

are:

WARNING

Keep hands, clothing and tools away

from the moving fan and engine drive

belt.

Be careful not to touch the engine,

power control unit, radiator, exhaust

manifold, etc., right after driving as

they may be hot. Oil and other fluids

may also be hot.

Do not leave anything that may burn

easily, such as paper and rags, in the

engine compartment.

Do not smoke, cause sparks or expose

an open flame to fuel. Fuel fumes are

flammable.

Take care because brake fluid can

harm your hands or eyes and damage

painted surfaces. If fluid gets on your

hands or in your eyes, flush the

affected area with clean water imme-

diately. If you still experience discom-

fort, consult a doctor.

When working near the electric cool-

ing fans or radiator grille

Be sure the power switch is OFF.

With the power switch in ON, the elec-

tric cooling fans may automatically start

to run if the air conditioning is on and/or

the coolant temperature is high.

Safety glasses

Wear safety glasses to prevent flying or

falling material, fluid spray, etc., from get-

ting in your eyes.

NOTICE

If you remove the air cleaner filter

Driving with the air cleaner filter

removed may cause excessive engine

wear due to dirt in the air.

If the fluid level is low or high

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 problem.
