Changing the bulbs
313Do not change xenon bulbs yourself, but
have them replaced at a qualified specialist
workshop which has the necessary special-
ist knowledge and tools to carry out the
work required.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist work-
shop.

could otherwise damage the LEDs or parts
of the vehicle. Overview

372 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 would
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 7.2 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 223).
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 223).
Adapt the mixing ratio to the outside tem-
peratures. G
Risk of fire
Windscreen washer concentrate is highly
flammable. Fire, naked flames and smoking
are prohibited when windscreen washer
concentrate is being handled. Technical data
