Windscreen washer concentrate is highly
flammable. Fire, naked flames and smoking
are prohibited when windscreen washer
concentrate is being handled.

R aw indscreen washer fluid additive
such as MB Summerwash to prevent

ing).
R aw indscreen washer fluid additive with

wash (if there is arisk of frost).

Brake fluid
Over aperiod 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 pocketsm ay form in the brake
system when the brakes are appliedh ard
(e.g. when driving downhill). This would
impair braking efficiency. Have the brake fluid renewed every two
years with
abrake fluid that has been
approved by Mercedes-Benz and have this
confirmed in the Service Booklet.
i There is usually anotic eint he engine
compartment to remind you when the next
brake fluid change is due. Windscreen washer system
The washer fluid reservoir holds approxi-
mately 7litres.
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 181).
