166 Checking and refilling
Checking fluid level
The fluid level must always be between the "M M A A X X " and "M M I I N N "
marks to ensure perfect operation.
The level of fluid tends to sink slightly when the vehicle is used
due to the automatic adjustment of brake linings. This is quite
normal.
If the level sinks noticeably in a short time or drops below the
"M M I I N N " mark, however, the system may be leaking. A low fluid level
in the reservoir is indicated by the brake warning lamp lighting up
"Warning lamps" chapter. G G o o t t o o a a T T e e c c h h n n i i c c a a l l S S e e r r v v i i c c e e C C e e n n t t r r e e

Renewing the brake fluid
Brake fluid absorbs moisture. In the course of time it takes in water
from the atmosphere. Too high a content of water in the brake fluid
system can cause corrosion damage. Furthermore the boiling point
of the brake fluid is reduced considerably. F F o o r r t t h h i i s s r r e e a a s s o o n n t t h h e e

Only our genuine brake fluid should be used (specification
according to US FM VSS 116 DOT 4 Standard). The fluid must be
new.
