WARNING
ARNING Risk of an accident due to
va pour poc kets form ing in the brake sys-
tem
The brake 0uid constantly absorbs moisture
from the air. This lo wersthe boiling point of
th e brake 0uid. If the boiling point is too lo w,
va pour poc kets may form inthe brake system
when the brakes are applied hard.
This impairs the braking e.ect. #
Have the brake 0uid rene we d at the
speci/ed inter vals. Ha
ve the brake 0uid regula rly re placed at a quali-
/ed specialist workshop.
