corrosion on the body and compo-
nents (aluminum wheels etc.)
●Wash the vehicle immediately in the
following cases:

■Cleaning the exterior lights
●Wash carefully. Do not use organic
substances or scrub with a hard brush.
This may damage the surfaces of the
lights.

ers may operate and the wiper blades
may be damaged.
■When using a high-pressure car wash
●When washing the vehicle, do not let
water of the high-p ressure washer hit
directly or the vicinity of the camera.
Due to the shock from the high-pres-
sure water, it is possible the device may
not operate as normal.

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
• 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
