may cause the charger to become hot

and cause burns or could cause elec-

tric shock resulting in death or serious

injury.

■

Cleaning the interior (especially

instrument panel)

Do not use a polish wax or polish cleaner.

The instrument panel may reflect off the

windshield, obstructing the driver’s view

and leading to an accident, resulting in

death or serious injury.

NOTICE

■

Cleaning detergents

●

Do not use the following types of

detergent, as they may discolor the

vehicle interior or cause streaks or

damage to painted surfaces:

• Non-seat portions: Organic sub-

stances such as benzene or gasoline,

alkaline or acidic solutions, dye, and

bleach

• Seats: Alkaline or acidic solutions,

such as thinner, benzene, and alcohol

●

cleaner. The instrument panel’s or

other interior part’s painted surface

may be damaged.

■

Preventing damage to leather sur-

faces

Observe the following precautions to

avoid damage to and deterioration of

leather surfaces:

●

Remove any dust or dirt from leather

surfaces immediately.

●

Do not expose the vehicle to direct

sunlight for extended periods of time.

Park the vehicle in the shade, espe-

cially during summer.

●

Do not place items made of vinyl, plas-

tic, or containing wax on the uphol-

stery, as they may stick to the leather

surface if the vehicle interior heats up

significantly.

■

Water on the floor

Do not wash the vehicle floor with water.

Vehicle systems such as the audio sys-

tem may be damaged if water comes into

contact with electrical components such

as the audio system above or under the

floor of the vehicle. Water may also

cause the body to rust.

Maintenance and

care



Remove dirt using a water-damp-
ened soft cloth or synthetic chamois.



Wipe the surface with a dry soft
cloth to remove any remaining
moisture.

■

Cleaning the areas with satin-finish

metal accents

The metal areas use a layer of real metal to

the surface. It is necessary to clean them

regularly. If dirty areas are left uncleaned

for long period of time, they may be difficult

to clean.



Remove dirt and dust using a vac-
uum cleaner.



Wipe off any excess dirt and dust
with a soft cloth dampened with
diluted detergent.

Use a diluted water solution of approxi-
mately 5% neutral wool detergent.



Wring out any excess water from
the cloth and thoroughly wipe off all
remaining traces of detergent.



Wipe the surface with a dry, soft
cloth to remove any remaining
moisture. Allow the leather to dry in
a shaded and ventilated area.

■

Caring for leather areas

Lexus recommends cleaning the interior of

the vehicle at least twice a year to maintain

the quality of the vehicle’s interior.



Remove dirt and dust using a vac-
uum cleaner.



Wipe it off with a soft cloth damp-
ened with neutral detergent diluted
to approximately 1%.



Wring out any excess water from
the cloth and thoroughly wipe off
remaining traces of detergent and
water.

Repair and replacement

It is recommended that genuine Lexus parts

be used for repairs to ensure performance

of each system. If non-Lexus parts are used

in replacement or if a repair shop other than

a Lexus dealer performs repairs, confirm

the warranty coverage.

■

Allow inspection and repairs to be per-

formed by a Lexus dealer

●

Lexus technicians are well-trained spe-

cialists and are kept up to date with the

latest service information. They are well

informed about the operation of all sys-

tems on your vehicle.

●

Keep a copy of the repair order. It proves

that the maintenance that has been per-

formed is under warranty coverage. If

any problem should arise while your vehi-

cle is under warranty, your Lexus dealer

will promptly take care of it.

General maintenance should be per-
formed on a daily basis. This can be
done by yourself or by a Lexus dealer.

Scheduled maintenance should be
performed at specified intervals
according to the maintenance sched-
ule.

For details about maintenance items and
schedules, refer to the “Warranty and Ser-
vice Guide”, “Owner’s Manual Supple-
ment” or “Scheduled Maintenance”.

ents, and a wide variety of automobile

components contain or emit chemicals

known to the State of California to

cause cancer and birth defects and

other reproductive harm. Work in a

well ventilated area.

●

Oils, fuels and fluids contained in vehi-

cles as well as waste produced by

component wear contain or emit

chemicals known to the State of Cali-

fornia to cause cancer and birth

defects or other reproductive harm.

Avoid exposure and wash any affected

area immediately.

●

Battery posts, terminals and related

accessories contain lead and lead

compounds which are known to cause

brain damage. Wash your hands after

WARNING

The engine compartment contains many

mechanisms and fluids that may move

suddenly, become hot, or become elec-

trically energized. To avoid death or seri-

ous injury, observe the following

precautions.

■

When working on the engine com-

partment

●

Keep hands, clothing and tools away

from the moving fan and engine drive

belt.

●

Be careful not to touch the engine,

engine 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 or the battery.

Fuel and battery fumes are flammable.

●

Be extremely cautious when working

on the battery. It contains poisonous

and corrosive sulfuric acid.

●

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 cooling fan

or radiator grille

Be sure the engine switch is off. With the

engine switch in ON, the cooling fan may

automatically start to run if the air condi-

tioning is on and/or the coolant tempera-

ture is high. (



■

When working on or under the vehi-

cle

Do not get under the vehicle with just the

jack supporting it. Always use automo-

tive jack stands or other solid supports.

Maintenance and

care

Pull the hood lock release lever.

The hood will pop up slightly.

Pull up the auxiliary catch lever and
lift the hood.

WARNING

■

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.

Hood

Release the lock from the inside of
the vehicle to open the hood.

Opening the hood

WARNING

■

Pre-driving check

Check that the hood is fully closed and

locked.

If the hood is not locked properly, it may

open while the vehicle is in motion and

cause an accident, which may result in

death or serious injury.

WARNING

■

Used engine oil

●

Used engine oil contains potentially

harmful contaminants which may

cause skin disorders such as inflamma-

tion and skin cancer, so care should be

taken to avoid prolonged and

repeated contact. To remove used

engine oil from your skin, wash thor-

oughly with soap and water.

●

Dispose of used oil and filters only in a

safe and acceptable manner. Do not

dispose of used oil and filters in house-

hold trash, in sewers or onto the

ground. Call your Lexus dealer, ser-

vice station or auto parts store for

information concerning recycling or

disposal.
