WARNING Risk of an accident due to
va por poc kets form ing in the brake sys‐
te m
The brake fluid cons tantly absorbs moist ure
from the air. This lo wersthe boiling point of
th e brake fluid. Ifth e boiling point is too lo w,
va por poc kets may form inthe brake sy stem
when the brakes are applied hard.
This causes the braking ef fect to be
impaired.
#Ha ve the brake fluid rene we d at the
specified inter vals.
Ha ve the brake fluid regularly changed at a quali‐
fi ed specialist workshop.
