Fuel
Important safety notes
GWARNIN G
Fuel is highly flammable. If you handle fuel
incorrectly, there is aris kof fir eand explo-
sion .
You must avoi dfire, open flames, creating
sparks and smoking. Switc hoff th eengin e
and ,if applicable, th eauxiliary heating before
refueling.
GWARNIN G
Fuel is poisonous and hazardous to health.
Ther eis aris kof injury.
You must mak esure that fuel does no tcome
int ocontact wit hyour skin, eyes or clothing
and that it is no tswallowed. Do no tinhale fuel
vapors. Kee pfuel away from children .
If you or other scome int ocontact wit hfuel ,
observ eth efollowing:
RWash away fuel from skin immediately
usin gsoap and water.
RIf fuel comes int ocontact wit hyour eyes,
immediately rinse them thoroughly wit h
clean water. Seek medical assistanc ewith-
out delay.
RIf fuel is swallowed, seek medical assis-
tance without delay. Do no tinduce vomit -
ing .
RImmediately chang eout of clothing whic h
has come int ocontact wit hfuel .

Fuel grade
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the ignition
if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system.
Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. Notify a qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
!Only refuel using unleaded premium grade
gasoline with at least 91 AKI/95 RON.
!Only use the fuel recommended. Operating
the vehicle with other fuels can lead to engine failure.
!Do not use the following:
RE85 (gasoline with 85% ethanol)
RE100 (100% ethanol)
RM15 (gasoline with 15% methanol)
RM30 (gasoline with 30% methanol)
RM85 (gasoline with 85% methanol)
RM100 (100% methanol)
RGasoline with metalliferous additives
RDiesel
Do not mix such fuels with the fuel recom-
mended for your vehicle. Do not use addi-
tives. Otherwise, engine damage may occur.
This does not include cleaning additives for
the removal and prevention of residue build-
up. Gasoline may only be mixed with cleaning
additives recommended by Mercedes-Benz;
see "Additives". You can obtain further infor-
mation from any authorized Mercedes-Benz
Center.
!To ensure the longevity and full perform-
ance of the engine, only premium-grade
unleaded gasoline must be used.

Coolant
Important safety notes
GWARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
!Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants can be found
in the Mercedes-Benz Specifications for Ser-
vice Products, MB BeVo 310.1, e.g. on the
Internet at http://bevo.mercedes-benz.com.
Or contact a qualified specialist workshop.
!Always use a suitable coolant mixture, even
in countries where high temperatures prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
iHave the coolant regularly replaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Comply with the important safety precautions
for service products when handling coolant
(
Ypage 289).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the fol-
lowin g t
asks:
Rcorrosion protection
Rantifreeze protection
Rraising the boiling point
If the coolant has antifreeze protection down to -35 ‡(-37 †), the boiling point of the coolant in
the pressurized system is approximately 266 ‡ (130 †). The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
Rbe at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35 ‡ (-37 †).
Rnot exceed 55% (antifreeze protection down
to -49
‡[-45 †]) .Otherwise ,hea twill no tbe
dissipated as effectively.

corrosion inhibitor in accordance wit hMB Spec -
ification sfo rServic eProducts 310.1.

Yo ur vehicle has a ran ge of alum
inum compo-
nents. Aluminum components in the engine
make itnecessary to use antifreeze/corrosion
inh ibit or that has been specific allyformulated to
protect the aluminum parts. Failure to use such
anticorrosion/antifreeze coolant willresult in a
significantly shortened service life.
The coolant must beused throughout the year in
order to maintain the necessary corrosion pro-
tection and to provide protection from over-
heating. Inthe Maintenance Booklet, you can
find information on the intervals for renewal.
The renewal interval is determined bythe cool-
ant type and the engine co oling system design.
The renewal interval in the Maintenance Booklet
is only valid if the coolant is renewed or added to
wit h Mercedes-Benz approved products. There-
fore, only use MB 326.0 antifreeze/corrosion
inh ibit or or another Mercedes-Benz approved
product of the same specification.
In formation on other products with the same
specifications that are approved byMercedes-
Benz can beobtained at an authorized
Mercedes-Benz Center or on the Internet at
ht tp://bevo.mercedes-benz.com .
If the coolant level is too low, MB 325.0 anti-
freeze/corrosion inh ibitor should beadded.
Have the engine co oling system c
hecked for
possible leaks.
