Maintenance and care
●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.
■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 insufficie nt, 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.154)
If AUTO mode is selected, 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 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

2826-1. Maintenance and care
WARNING
■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 fo llowing systems may
not function correctly. If this occurs, con-
sult your Lexus dealer.
