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.

The brake fluid level is correct if it is between MIN marking 2 and MAX marking 1 on the brake fluid reservoir.
