●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
■Brake caliper coating (F SPORT mod-
els)
●When using detergent, use neutral deter-
gent. Do not use hard brushes or abra-
sive cleaners, as they will damage the
paint.
●Do not use detergent on the brake cali-
pers when they are hot.
●Wash detergent off immediately after
use.
■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.
■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 side win- dows 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 (vehi-
cles with rain-sensing windshield wip-
ers)
Set the wipers to the intermittent wind-
shield wipers. (
P.145)

ing situations, and may result in hands
being caught or other serious injuries
and cause damage to the wiper blades.

the exhaust pipes while the engine is run-
ning or immediately after the engine is

to touch the exhaust pipes until they have
cooled sufficiently, as touching hot
exhaust pipes can cause burns.

tion. If this occurs, consult your Lexus
