l Brake fluid
Over a period of time, the brake fluid absorbs
moisture from the air; this lowers its boiling
point. G
Risk of accident
If the boiling point of the brake fluid is too
low, vapour pockets may form in the brake
system when the brakes are applied hard
(e.g. when driving downhill). This woul d
impair braking efficiency.
Have the brake fluid renewed every two
years with a brake fluid that has been approved by Mercedes-Benz and have this
confirmed in the Service Booklet.
i There is usually a notice in the engine
compartment to remind you when the next
brake fluid change is due. Windscreen washer system
The washer fluid reservoir holds approxi-
mately 7 litres.
The headlamp cleaning system* and the
windscreen washer system are both supplied
from the washer fluid reservoir.
X At temperatures above freezing point:
Top up the washer fluid reservoir with a
mixture of water and windscreen washer
concentrate (Y page 154).
X At temperatures below freezing point:
Top up the washer fluid reservoir with a
mixture of water, antifreeze and wind-
screen washer concentrate (Y page 154). Technical data
