Maintenance and care
■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 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 wiper switch to off.
If the wiper switch is in “AUTO”, the wip-
ers may operate unexpectedly in the fol-

●If something bumps against the wind-
shield
●If you directly touch the raindrop sen-
sor body or if something bumps into

pipes and rear bumper diffusers to
become quite hot, do not touch the
exhaust pipes and rear bumper diffusers
while the engine is running or immedi-
ately after the engine is turned off.
When washing the vehicle, be careful not
to touch the exhaust pipes and rear
bumper diffusers until they have cooled
sufficiently, as touching hot exhaust pipes
and rear bumper diffusers can cause
burns.
