Observe the notes on operating fluids.
WARNING Risk of an accident due to vapor pockets forming in the brake system
The brake fluid constantly absorbs moisture from the air. This lowers the boiling point of the brake fluid. If the boiling point is too low, vapor pockets may form in the brake system when the brakes are applied hard.
This causes the braking effect to be impaired.
Have the brake fluid renewed at the specified intervals.
Have the brake fluid regularly replaced at a qualified specialist workshop.
Only use a brake fluid approved by Mercedes- Benz according to MB-Freigabe or MB-Approval 331.0.
