Maintenance and care
■Bumpers
Do not scrub with abrasive cleaners.
■Front side windows water-repellent
coating (vehicles with 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.
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 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
pipe
Exhaust gasses cause the exhaust pipe to
become quite hot.
When washing the vehicle, be careful not
to touch the pipe until it has cooled suffi-
ciently, as touching a hot exhaust pipe
can cause burns.
■Precautions regarding the rear
bumper with Blind Spot Monitor (if
equipped)
If the paint of the re ar bumper is chipped
or scratched, the system may malfunc-
tion. If this occurs, consult your Lexus
dealer.
