NOTICE
■When using an automatic car
wash (vehicles with rain-
sensing windshield wipers)
Set the wiper switch to off posi-
tion.
If the wiper switch is in “AUTO”,
the wipers may operate and the
wiper blades may be damaged.
■When using a high pressure
car wash
●When washing the vehicle, do
not let water from the high-pres-
sure washer directly hit the
camera or the area around the
camera. Due to th e shock from
the high pressure water, it is
possible that the device may not
operate normally.
●Do not spray water directly on
the radar which is equipped
behind the radar sensor cover.
Otherwise it may cause the
device to be damaged.
●Do not bring the nozzle tip close
to boots (rubber or resin manu-
factured cover), or connectors
or the following parts.
The parts may be damaged if
they come into contact with
high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
●Keep the cleaning nozzle at
least 11.9 in. (30 cm) away from
the vehicle body. Otherwise
resin section, such as moldings
and bumpers, may be deformed
and damaged. Also, do not con-
tinuously hold the nozzle in the
same place.
●Do not spray the lower part of
the windshield continuously. If
water enters the air conditioning
system intake located near the
lower part of the windshield, the
air conditioning system may not
operate correctly.
●Do not wash the underside of

sure car washer.
