6-1.Maintenance and care
Working from top to bottom, liber-
ally apply water to the vehicle body,
wheel wells and underside of the
vehicle to remove any dirt and dust.
 Wash the vehicle body using a
sponge or soft cloth, such as a
chamois.
 For hard-to-remove marks, use car
wash soap and rinse thoroughly with
water.
 Wipe away any water.
 Wax the vehicle when the water-
proof coating deteriorates.
If water does not bead on a clean surface,
apply wax when the vehicle body is cool.
■Black stainless steel window moldings
(IS500)
The stainless steel window moldings are
made of black oxide coated stainless steel.
When cleaning the vehicle, do not scrub the
moldings with an abrasive cleaner as their
finish may be damaged or the color may
change.
■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 contains abrasives.
■Automatic car washes
●Fold the mirrors before washing the vehi-
cle. Start washing from the front of the
vehicle. Make sure to extend the mirrors
before driving.
●Brushes used in automatic car washes
may scratch the vehicle surface, parts
(wheel, etc.) and damage the paint.
■High pressure car washes
As water may enter the cabin, do not bring
the nozzle tip near the gaps around the
doors or perimeter of the windows, or spray
these areas continuously.
■When using a car wash
If the door handle becomes wet while the
electronic key is within the effective range,
the door may lock and unlock repeatedly. In
that case, follow the following correction
procedures to wash the vehicle:
●Place the key in a position 6 ft. (2 m) or
more separate from the vehicle while the
vehicle is being washed. (Take care to
ensure that the key is not stolen.)
●Set the electronic key to battery-saving
mode to disable the smart access system
with push-button start. ( P.98)
■Wheels and wheel ornaments (vehicles
without matte black painted wheels)
●Remove any dirt immediately by using a
neutral detergent.
●Wash detergent off with water immedi-

Maintenance and care
ately after use.
●To protect the paint from damage, make
sure to observe the following precau-
tions.
• Do not use acidic, al kaline or abrasive
detergent
• Do not use hard brushes
• Do not use detergent on the wheels when they are hot, such as after driving or park-
ing in hot weather
■Wheels and wheel ornaments (vehicles
with matte black painted wheels)
As matte black painted wheels require dif-
ferent cleaning methods than conventional
aluminum wheels, be su re to observer the
following. For details, consult your Lexus
dealer.
●Remove dirt using water. If the wheels are
excessively dirty, use a sponge or soft
cloth dampened with a diluted neutral
detergent to remove the dirt.
●When using detergent, make sure to
rinse it off with water immediately. Then
use a soft cloth to wipe off the water.
●To prevent the matte black paint from
being damaged, make sure to observe
the following precautions:
• Do not scrub or polish the wheels using a brush or dry cloth.
• Do not use any wheel coatings or abra-sive detergents.
• When using an automatic car wash,
dis-able/do not select the wheel brush
func-tion(if such an option is available).
• Do not use a high pressure pressure
washer or steam cleaner.
• Do not use detergent on the wheels when they are hot, such as after driving or
park-ing in hot weather.
■Brake pads and calipers
Rust may form if the vehicle is parked with
wet brake pads or disc rotors, causing them
to stick. Before parking the vehicle after it is
washed, drive slowly and apply the brakes
several times to dry the parts.
■Bumpers
Do not scrub with abrasive cleaners.
■Front side windows water-repellent
coating (if equipped)
●The following precautions can extend the
effectiveness of the water-repellent coat-
ing.
• Remove any dirt, etc. from the front side windows regularly.
• Do not allow dirt and dust to accumulate
on the windows for a long period.
Clean the windows with a soft, damp
cloth as soon as possible.
• Do not use wax or glass cleaners that contain abrasives when cleaning the win-
dows.
• Do not use any metallic objects to remove condensation build up.
●When the water-repellent performance
has become insufficient, the coating can
be repaired. Contact your Lexus dealer.
■Plated portions
If dirt cannot be removed, clean the parts as
follows:
●Use a soft cloth dampened with an
approximately 5% solution of neutral
detergent and water to clean the dirt off.
●Wipe the surface with a dry, soft cloth to
remove any remaining moisture.
●To remove oily deposits, use alcohol wet
wipes or a similar product.
WARNING
■When washing the vehicle
Do not apply water to the inside of the
engine compartment. Doing so may
cause the electrical components, etc. to
catch fire.

2726-1. Maintenance and care
WARNING
■When cleaning the windshield (vehi-
cles with rain-sensing windshield wip-
ers)
Set the wipers to the intermittent wind-
shield wipers. ( P.150)
If AUTO mode is se lected, the wipers
may operate unexpectedly in the follow-
ing situations, and may result in hands
being caught or other serious injuries
and cause damage to the wiper blades.
●When the upper part of the windshield
where the raindrop sensor is located is
touched by hand
●When a wet rag or si milar is held close
to the raindrop sensor
●If something bumps against the wind-
shield
●If you directly touch the raindrop sen-
sor body or if something bumps into
the raindrop sensor
■Precautions regarding the exhaust
pipes and rear bumper diffusers
Exhaust gases cause the exhaust pipes
and rear bumper diffusers to become
quite hot.
When washing the vehicle, be careful not
to touch the pipes and diffusers until they
have cooled sufficiently, as touching hot
exhaust pipes and rear bumper diffusers
can cause burns.
■Precaution regarding the rear
bumper
If the paint of the rear bumper is chipped
or scratched, the following systems may
not function correctly. If this occurs, con-
sult your Lexus dealer.
●Lexus Safety System + 2.5
●BSM
●RCTA
●PKSB (if equipped)
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 or tree sap is present on the paint surface
• If dead insects, insect 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 chipped 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.

Maintenance and care
NOTICE
■When using an automatic car wash
(vehicles with rain-sensing windshield
wipers)
Set the wiper switch to the off position.
( P.150)

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 pressure 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 spray water directly on the
radar which is equipped behind the
emblem. Otherwise it may cause the
device to be damaged.
●Do not bring the nozzle tip close to
boots (rubber or re sin 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 near the lower part of
the windshield, the air conditioning sys-
tem may not oper ate correctly.
●Do not wash the underside of the vehi-
cle using a high pressure car washer.
