Brake fluid level
If you notice that the brake fluid level in
the brake fluid reservoir has fallen to the
MIN mark or less, check the brake system
immediately for leaks. Also check the
thickness of the brake linings. Contact a
qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center
immediately.
Do not add brake fluid. This does not
correct the error.
Only check the brake fluid level when the vehicle is stationary and on a level surface.
In order to check the brake fluid level, the cover above the brake fluid reservoir must be removed.

– Remove seal 2 in the area around cover 1 in the direction of the arrow.

– Raise cover 1 at the front.
– Pull out cover 1 in the direction of the
arrow.

The brake fluid level is correct if it is between MIN marking 4 and MAX marking 3 on the brake fluid reservoir.
Cover 1 is installed in the reverse order.
When doing so, make sure that the guides of cover 1 engage in the slots in the bulkhead.
