tions.
• Do not use acidic, a lkaline 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.
■Bumpers

■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 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 wipers to the intermittent wind-
shield wipers. ( P.141)
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
■Precautions regarding the exhaust
pipes
As exhaust gases cause the exhaust
pipes to become quite hot, do not touch
the exhaust pipes while the engine is run-
ning or immediately after the engine is
turned off.
When washing the vehicle, be careful not
to touch the exhaust pi pes until they have
cooled sufficiently, as touching hot
exhaust pipes can cause burns.

If AUTO mode is selected, the wipers
may operate and the wiper blades may
be damaged.
■When using a high pressure car wash
●When washing the vehicle, do not
spray the camera or its surrounding
area directly with a high pressure
washer. Shock applied from high pres-
sure water may cause the device to not
operate normally.
●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
• Suspension parts
• Steering parts
• Brake parts
●Keep the cleaning nozzle at least 11.9
in. (30 cm) away from the vehicle
