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.
■
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
●
Before washing the vehicle:
• Fold the mirrors
• Turn off the power back door
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.
■
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. (
■
Wheels and wheel ornaments
●
Remove any dirt immediately by using a
neutral detergent.
●
Wash detergent off with water immedi-
ately after use.
●
To protect the paint from damage, make
sure to observe the following precau-
tions.
• Do not use acidic, alkaline 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
Cleaning and protecting the
vehicle exterior
Perform cleaning in a manner
appropriate to each component
and its material.

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
●
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.
■
When cleaning the windshield
Set the wiper switch to off.
If the switch is in “AUTO”, the wipers may
operate unexpectedly in the following sit-
uations, and may result in hands being
caught or other serious injuries and
cause damage to the wiper blades.
Off
AUTO
●
When the upper part of the windshield
where the raindrop sensor is located is
touched by hand
●
When a wet rag or similar 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 gasses 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.

operate normally.
●
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 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 near the lower part of
the windshield, the air conditioning sys-
tem may not operate correctly.
●
Do not wash the underside of the vehi-
cle using a high pressure car washer.
