6-1. Maintenance and care

■

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.

■

Shampooing the carpets

There are several commercial foaming-type cleaners available. Use a sponge or brush to

apply the foam. Rub in overlapping circles. Do not use water. The excellent results are

obtained when keeping the carpet as dry as possible.

■

Seat belts

Clean with mild soap and lukewarm water using a cloth or sponge. Also check the belts

periodically for excessive wear, fraying or cuts.

WARNING

■

Water in the vehicle

●

Do not splash or spill liquid in the vehicle.

Doing so may cause electrical components etc. to malfunction or catch fire.

●

Do not get any of the SRS components or wiring in the vehicle interior wet. (



P. 40)

An electrical malfunction may cause the airbags to deploy or not function properly,

resulting in death or serious injury.

■

Cleaning the interior (especially instrument panel)

Do not use polish wax or polish cleaner. The instrument panel may reflect off the wind-

shield, 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 substances such as benzene or gasoline, alkaline or

acidic solutions, dye, and bleach

• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alcohol

●

Do not use polish wax or polish cleaner. The instrument panel’s or other interior part’s

painted surface may be damaged.

NOTICE

■

Preventing damage to leather surfaces

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, especially during summer.

●

Do not place items made of vinyl, plastic, or containing wax on the upholstery, as they

may stick to the leather surface if the vehicle interior heats up significantly.

■

When cleaning the inside of the windshield (vehicles with Lexus Safety System +)

Do not allow glass cleaner to contact the lens. Also, do not touch the lens. (



P. 252)

■

Water on the floor

Do not wash the vehicle floor with water.

Vehicle systems such as the audio system 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.

■

Cleaning the inside of the rear quarter windows and rear window

●

Do not use glass cleaner to clean the rear quarter windows and rear window, as this

may cause damage to the rear window defogger heater wires or antenna. Use a cloth

dampened with lukewarm water to gently wipe the window clean. Wipe the window

in strokes running parallel to the heater wires or antenna.

●

Be careful not to scratch or damage the heater wires or antenna.

Emission inspection and maintenance (I/M) programs

The OBD system determines that a problem exists somewhere in the emission
control system. Your vehicle may not pass the I/M test and may need to be
repaired. Contact your Lexus dealer to service the vehicle.

●

When the battery is disconnected or discharged
Readiness codes that are set during ordinary driving are erased.
Also, depending on your driving habits, the readiness codes may not be com-
pletely set.

●

When the fuel tank cap is loose
The malfunction indicator lamp comes on indicating a temporary malfunction
and your vehicle may not pass the I/M test.

The error code in the OBD system will not be cleared unless the vehicle is driven
40 or more times.

Contact your Lexus dealer to prepare the vehicle for re-testing.

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.

If the malfunction indicator lamp comes on

Your vehicle may not pass the I/M test in the following situations:

When the malfunction indicator lamp still remains on after several driv-
ing trips

If your vehicle does not pass the I/M test

WARNING

The engine compartment contains many mechanisms and fluids that may move suddenly,

become hot, or become electrically energized. To avoid death or serious injury, observe

the following precautions:

■

When working on the engine compartment

●

Keep hands, clothing and tools away from the moving fan and engine drive belt.

●

Be careful not to touch the 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 or rags, in the engine com-

partment.

●

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 corro-

sive sulfuric acid.

■

When working near the electric cooling fans or radiator grille

Be sure the engine switch is off. With the engine switch in IGNITION ON mode, the

electric cooling fans may automatically start to run if the air conditioning is on and/or

the coolant temperature is high. (



P. 483)

■

When working on or under the vehicle

Do not get under the vehicle with just the jack supporting it.

Always use automotive jack stands or other solid supports.

■

Safety glasses

Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting in

your eyes.

NOTICE
