PRECAUTIONS

PRECAUTIONS

PFP:00001

Precautions for Battery Service

NCS0009V

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

Service Notice or Precaution

NCS0009W

●

Recommended fluid is brake fluid “DOT 3”. Refer to 

MA-10, "RECOMMENDED FLUIDS AND LUBRI-

CANTS"

 .

●

Never reuse drained brake fluid.

●

Be careful not to splash brake fluid on painted areas.

●

When removing and installing clutch piping, use Tool.

●

Use new brake fluid to clean or wash all parts of master cylinder
and operating cylinder.

●

Never use mineral oils such as gasoline or kerosene. It will ruin
the rubber parts of the hydraulic system.

WARNING:

After cleaning clutch disc, wipe it with a dust collector. Do not
use compressed air.
