CAUTION!

Use only fresh brake fluid conforming to US
standard FMVSS 116 DOT 4. Genuine
VW/Audi brake fluid conforms to this
specification.
Brake fluid must never be brought into
contact with liquids containing mineral oil
(gasoline, cleaning agents). Mineral oil
damages the pistons and cups in the braking
system.
Brake fluid must not be allowed to come into
contact with paintwork because of its caustic
effect.
Brake fluid is hygroscopic (i.e. it absorbs
moisture from the surrounding air) and
should therefore always be kept in airtight
containers.
When carrying out the following steps, make
sure that no brake fluid escapes onto the
transmission.

Notes:
The clutch system must be bled after carrying
out work on the hydraulic clutch mechanism.
