Brake fluid
WARNING 
The brake fluid constantly absorbs moisture
from the air; this lowers its boiling point.
If the boiling point of the brake fluid is too low,
vapor pockets may form in the brake system when the brakes are applied hard
(e.g. when
driving downhill). This would impair braking
efficiency.
You should have the brake fluid renewed at
regular intervals. The brake fluid change
intervals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes- Benz. Information about approved brake fluids can be obtained from any authorized Mercedes-Benz Center.
