RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)NOTICE ■
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 appli ed from high pressure water may cause the
device to not operate normally. ●
Do not bring the nozzle tip close to boots (rubber or resin manufactured cover), con-
nectors or the following parts. The parts may be damaged if they come into contact
with high-pressure water.
■
Hood vent (RC F)• Traction related parts
• Steering parts • Suspension parts
• Brake parts●
RC F: Do not point the nozzle of a high pres-
sure washer at the areas shown in the illustra-
tion, as high pressure water may damage the
oil coolers.
When washing the vehicle, do not allow a large
amount of water to enter the hood vent at once,
such as when using a bucket, etc. or point the
nozzle of a high pressure washer at the hood
vent.
Water may get inside the engine compartment
and affect the engine and other components.
