Notes on brake fluid
Obser vethe no tes on operating fluids
(→page 387).
0071 WARNING Risk of an accident due to
va por poc kets form ing in the brake sys‐
te m
The brake fluid constantly absorbs moisture
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.
00BBHa 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.
Only use brake fluid appr ovedby Mercedes-Benz
