WARNING
■Precaution regarding the rear
bumper with Blind Spot Monitor (if
equipped)
If the paint of the rear bumper is chipped
or scratched, the system may malfunc-
tion. If this occurs, consult your Lexus
dealer.
NOTICE
■To prevent paint deterioration and
corrosion on the body and compo-
nents (aluminum wheels etc.)
●Wash the vehicle immediately in the
following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar, pollen or tree sap is present on the paint surface
• If dead insects, in sect droppings or
bird droppings are present on the
paint surface
• After driving in an area contaminated with soot, oily smoke, mine dust, iron
powder or chemical substances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gasoline are spilled on the paint surface
●If the paint is chip ped or scratched,
have it repaired immediately.
●To prevent the wheels from corroding,
remove any dirt and store in a place
with low humidity when storing the
wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic
substances or scrub with a hard brush.
This may damage the surfaces of the
lights.
●Do not apply wax to the surfaces of the
lights.
Wax may cause damage to the lenses.
■When using an automatic car wash
(vehicles with rain-sensing windshield
wipers)
Set the wiper switch to the off position.
If the wiper switch is in “AUTO”, the wip-
ers may operate and the wiper blades
may be damaged.
■When using a high-pressure car wash
●When washing the vehicle, do not let
water of the high-p ressure washer hit
directly or the vicinity of the camera.
Due to the shock from the high-pres-
sure water, it is possible the device
may not operate as normal.
●Do not bring the nozzle tip close to
boots (rubber or resin manufactured
cover), connectors or the following
parts. The parts may be damaged if
they come into contact with high-pres-
sure water.
• Traction related parts
•Steering parts
• Suspension parts
• Brake parts
●Keep the cleaning nozzle at least 11.9
in. (30 cm) away from the vehicle
body. Otherwise resin section, such as
moldings and bumpers, may be
deformed and damaged.
Also, do not continuously hold the
nozzle in the same place.
●Do not spray the lower part of the
windshield continuously.
If water enters the air conditioning sys-
tem intake located ne ar the lower part
of the windshield, th e air conditioning
system may not operate correctly.
●Do not wash the underside of the vehi-
cle using a high pressure car washer.

3106-1. 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 for
the surface. It is necessary to clean them
regularly. If dirty areas are left uncleaned
for long periods of time, they may be diffi-
cult 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 cleani ng the interior of
the vehicle at least twice a year to maintain
the quality of the vehicle’s interior.
NOTICE
■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.
■When cleaning the inside of the wind-
shield
Do not allow glass cleaner to contact the
lens. Also, do not touch the lens.
(  P.174)
■Cleaning the inside of the rear win-
dow
●Do not use glass cleaner to clean the
rear window, as this may cause dam-
age 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.

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
●Make sure that the “IGNITION ON”
on the multi-information display and
the “READY” indicator are both off.
●Keep hands, clothi ng and tools away
from the moving fan and engine drive
belt.
●Be careful not to touch the engine,
power control unit, radiator, exhaust

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.
ItemsParts and tools●Do not smoke, cause sparks or expose
an open flame to fuel. Fuel fumes are
flammable.
■When working near the electric cool-
ing fan or radiator grille
Be sure the power switch is off.
With the power switch in ON mode, the
electric cooling fan may automatically
start to run if the air conditioning is on
and/or the coolant temperature is high.
(  P.324)
■Safety glasses
Wear safety glasses to prevent flying or
falling material, fluid spray, etc. from get-
ting in your eyes.

■Brake fluid can absorb moisture from
the air
Excess moisture in the brake fluid can
cause a dangerous loss of braking effi-
ciency. Use only newly opened brake fluid.
If any washer does not work or “Wind-
shield Washer Fluid Low” is shown on
the multi-information display, the
washer tank may be empty. Add
washer fluid.
WARNING

WARNING
■When filling the reservoir
Take care as brake fluid can harm your
hands and eyes and damage painted sur-
faces.
If fluid gets on your hands or in your eyes,
flush the affected area with clean water
immediately.
If you still experience discomfort, see a
doctor.
NOTICE
■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 out
or when the fluid leve l in the accumulator
is high.
If the reservoir needs frequent refilling,
there may be a serious problem.
