The yellow reserve fuel
warnin
glamp lights up
while the engine is run-
ning. The fuel level has fallen below the reserve range.
The fuel tank must be filled at least to the reserve fuel level to
prevent impairment to the running of the engine.
X Refuel at the nearest filling station. ?
The red coolant warn-
ing lamp lights up while
the engine is running
and the coolant tem-
perature gauge is at the
start of the scale.
The temperature senso
rfor the coolant temperatur egauge is
faulty.
The coolant temperature is no longer being monitored. There is a
risk of engine damage if the coolant temperature is too high.
X Pull over and stop the vehicle safely and switch off the engine,
paying attention to road and traffic conditions. Do not continue
driving under any circumstances.
X Engage the parking brake.
X Consult aqualified specialist workshop. ?
The red coolant warn-
ing lamp comes on
while the engine is run-
ning.
The coolant level is too low.
If the coolant level is correct, the airflow to the radiator may be
blocked or the electric radiator fan may be malfunctioning.
The coolant is too hot and the engine is no longer being cooled
sufficiently.
X Pull over and stop the vehicle safely and switch off the engine,
paying attention to road and traffic conditions.
X Allow the engine and coolant to cool.
X Check the coolant level and top up the coolant (Y page 261).

engine coolant system checked.
X Make sure that the air suppl ytot he radiator is not blocked, e.g.
by snow, slush or ice.
X If the coolant temperature is less than 12 0†,you can con tinue
driving to the neares tqualified specialist workshop.
X Avoid subjecting the engine to heavy loads ,e.g. driving in moun-
tainous terrain, and stop-s tart driving. ?
Th

H
Environmenta
lnote
When toppin guptheoil, tak ecaren ot to spill
any .Ifo il enter sthe soil or waterways, it is
harmful to the environmen t.Engine oil cap (example)
X
Turn cap :anti-clockwise and remove it.
X Top up with the amount of oil required.
Fill carefully to the maximum mark on the oil
dipstick.
i Depending on the engine, the difference
between the minimum mark and the maxi-
mum mark is approximately 1.5 –2litres.
! Do not add too muc hoil. If the oil level is
above the "max "mark on the dipstick, too
much oil has been added. This can lead to
damage to the engine or the catalytic con-
verter .Have excess oil siphoned off.

the instrument cluster. G
Risk of injury
The cooling system is pressurised. Therefore,
only unscrew the cap once the engine has
cooled down. The coolant temperature gauge
must display less than 70 †.Otherwi se,you
could be scalded if ho tcoolant escapes. X
Slowl yturn cap :half aturna nti-clock-

Coolant
Important safety notes The coolan
tisamixture of water and anti-
freeze/corrosio ninhibitor. It performs the
following tasks:
R anti-corrosio nprotection
R antifreeze protection
R raising th eboiling point
i When the vehicle is first delivered, it is fil-
led with acoolant mixtur ethat ensures
adequate antifreeze and corrosion protec-
tion.
! Only top up with coolant that has been
premixed with the desired antifreeze pro-
tec tion. You coul dotherwis edamage the
engine.
Further information on coolants and on fill-
ing can be found in the Mercedes-Benz
Specifications for Service Products, MB
Approval 310.1 ,e.g. on the Internet at
http ://bevo.mercedes-benz.com .You can
also consult aMercedes-Benz Service
Centre.
! Alway suseasuitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the cooling system will not be
sufficiently protected from corrosion, and
the boiling point will be too low.
If antifreeze/corrosio ninhibitor is present in
the correc tconcentration, the boilin gpoint of
the coolant will be around 13 0†.
The antifreeze/ corrosion inhibitor con centra-
tion in the cooling system should:
R be at leas t50%. This wil lprotect the cooling
system against freezing down to around
37 †.
R not exceed 55% (antifreeze protection
down to -45 †); otherwise ,heat will not be
dissipated as effectively. If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor-
rosion inhibitor. Mercedes-Ben
zrecom-
mends an anti freeze/cor rosion inhibitor
whic hhas been approved for Mercedes -Benz.
! The coolin gsystem is filled with coolant
which must be renewed after 15 years, or
after 250,000 km at the latest.
The warrant yisonly valid if you top up with
an antifreeze /corrosion inhibitor which
has been approved by Mercedes-Ben zand
