wheels when they are hot, such
as after driving or parking in hot
weather
■ 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.
■ 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 alco-
hol 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 com-
ponents, etc. to catch fire.

(vehicles with rain-sensing
windshield wipers)
Set the wiper switch to off.
If the wiper switch is in "AUTO",
the wipers may operate unexpect-
edly in the following situations,
and may result in hands being
caught or other serious injuries
and cause damage to the wiper
blades.

Off
B
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 sen-
sor
● If something bumps against the
windshield
● If you directly touch the raindrop
sensor body or if something
bumps into the raindrop sensor
■ Precautions regarding the
exhaust pipes
Exhaust gasses cause the
exhaust pipes to become quite
hot.
When washing the vehicle, be
careful not to touch the pipes until
they have cooled sufficiently, as
touching hot exhaust pipes can
cause burns.
