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 applie d 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.

■Checking fluid level
The brake fluid level should be between the “MAX” and “MIN” lines on the
tank.
■Adding fluid
Make sure to check the fluid type and prepare the necessary items.
■Brake fluid can absorb moisture from the air
Excess moisture in the brake fluid can cause a dangerous loss of braking efficiency. Use
only newly opened brake fluid.

■When filling the reservoir
Take care as brake fluid can harm your hands and eyes and damage painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with clean water
immediately.
If you still experience discomfort, see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear out or
when the fluid level in the accumulator is high.
If the reservoir needs frequent refil ling, there may be a serious problem.
