358 Practical advice
Changing bulbs Be
fore changing a bulb
! Only fit 12V bulbs of the same type as
before and of the correct wattage.
! Switch off the lights before changing a
bulbto avoid a short-cir cuit. !
Only hold bulbs with a clean, lint-free
cloth.
! Do not work with wet or greasy fingers.
! If the new bulb sti lldoes not light up,
visit a qualified specialist workshop,
e.g. a Merce des-Benz Service Centre.
! Have theLEDs and bulbs spec ifiedbe-
low replaced at a qualified specialist
workshop, e.g. a Mercedes-Benz Serv-
ice Centre. These are the:
! additional turn sign als in the exteri-
or mirrors
! third brake lamp
! front fog lamp bulbs
! xenon bulbs*
i Have the headlamp setting checked
regularly. G
Risk of inju ry Bulbs and lamps can be
come very hot. You
should therefore allow them to cool down
before you cha nge them.
Kee p bulbs out ofthe reach of children.
Never use abulb which has been dropped.
Such a bulb may explode and injure you.
H7 bulbs are pressurised and may explode
when they ar echanged. You should there-
fore wear eye protection and gloves when
you are changin gthem. G
Risk of injury Xe
non bulbs carry ahigh voltage. Do not re-
move the cover of the xenon bulb. Do not
change the xenon bulbs yourself. You should
hav e them chan gedat a qualified speci alist
workshop whic hhas th e necessary special-
ist knowledge and tools to carry out the
work requ ired. Mercedes-Benz recommends
that you use a Mercedes-Benz Service Cen-
tre for this purpose. In parti cular, work rele-
va nt to safety or onsafety-relate dsystems
must be carried out at a quali fied specialist
wor kshop. 209en_d2.boo Seite

416 Technical data
Service products and capacities
The antifreeze and corrosion inhibitor con-
centration in the cooling system should:
! be at least 50%. This will pro tect the
cool ing sy stem against freezing down
to approximately –37 °C.
! not exceed 55% (antifreeze protection
down to –45 °C), since the heat is then
not dissipated as effectively.
If the vehicle has lost coolant, top it up with
equal parts of water and an antifreeze and
corrosion inhibitor. Mercedes-Benz recom-
mends that you use an antifreeze and cor-
rosion inhibitor which has been approved
for Mercedes-Benz.
! The co oling system has a permanent supply
which must be renewed after 15 years or
250,000 km at the most.
Merc edes-Be nzrecommends that you use an an-
tifreeze and cor rosion inhibitor which has been
appr oved for Mercedes-Benz. Over a period of time, the brake fluid ab-
sorbs moisture from the air; this reduces
its boiling point.

There is usually a notice in the engine com-
partment to remind you when the next brakeflu-
id change is due. The windscreen washer reservoir holds
approximately
3litres on all models with
aw indscreen washe rsystem. On models
with a heated windscreen washer fluid res-
ervoir ora headlamp cleaning system*, the
re servoir holds 6litres.
The head lamp cleaning system* and the
windscreen washer system have a com-
mon supply from the windscreen washer
fl uid reservoir.
6 Fill the windscreen washer fluid reser-
voirwith a solution of water and wind-
screen washer concentrate. Adapt the
mix ing ratio to sui tthe outsi detemper-
atures.
The windscreen wipers leave no marks.
The headlamp cleaning system and the
windscreen washer system do not
freeze. Brake fluid
G
Riskofaccident If the boiling
point of the brake fluid is too
low, vapour pockets may fo rmin the brake
system when the brak esare applied hard
(e.g. when driving dow nhill). This would im-
pair braki ngefficiency.
