D
The red coolant warning lamp
lights up wh ile the engine is
running. There is insufficient coolant in the reservoir. 6
Top up the coolant immediately, oth-
erwise the engine could ove rheat
(= page 247). If this warning lamp lights up frequently,
there is a leak in the cool
ing system. 6
Have the cooling system checked. If the coolant lev
elis correct, the radiator fan
may be faulty. 6
If the coolant temperature is below
12 5° C, you can drive on to the near-
est qualifie dspec ialist wor ksho p, e .g.
a Mercedes-Benz Servi ceCentre.
6 Avoid plac ing a heavy strai non the en-
gi ne (e.g. driving on mountain roads)
and stop /start driving. D
The red coolant warning lamp
lights up while you are dri ving
and you can hear an audible
warning. The coolant temperature has
exceeded
125 °C. 6
Stop as soon as possible and allow
the engine and the coolant to cool
down. 209en_d2.boo Seite

Practical advice
Tr ou bleshooting Problem Possible caus
e/consequ ence Suggested sol
utions The coolant temperature gauge is above
+130 °C. The coolant warning lamp may
also be
lit and a warning signal may sound
( = pag e107). The coolant
level is too low. The coolant is
too hot and the engine is no longer being
cooled sufficiently. 6
Stop as soon as possible and allow the
engine and the coolant to cool down.
6 Check the coolant level, while observing
the warn ings, and top up the coolant if
nec essary (
=page 247). If the coolant
level is correct, the radiator
fan may be faulty. The coolant is too hot
and the engine is no longer being coo led
sufficiently. 6
If the coolant temperature is below
130 °C ,you can drive on to the nearest
qual ified specialist workshop, e.g. a
Mercedes-Benz Serv ice Ce ntre.
6 When doing so, avoid placing a heavy
strain on the engine (e.g. driving on
mo untain roads) and stop /start driving. 209en_d2.boo Seite

Te
chnical data
Service products and capacities
The following values indicate the various
total cooling system capacities.
Co rrosion in hibitorand antifreeze
concentration for antifreeze protection down to –45 °C (55%)
The coolant is a mixture of water, corro-
sion inhibitor and antifreeze. It performs
the following functions in the coo
ling sys-
tem:
! Anti-corrosion protection
! Antifreeze protection
! Raising the boiling point !
Always use a suitable coolan t–even in
co untri eswith high temperature s.
If you do not do so, the cooling system will not be
suffici ently protected from corrosion, and the
boiling point wil lbe too low. If antifreeze
/corrosion inhibitor is present
in the correct concentration, the boiling
point of the coolant will be around 130 °C. Coolant

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.
Have the brake fluid renewed every
tw oy ears. Windscreen washer sys

Riskof fire Winds
creen washer concentrate is highly
