If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
! Only use fuses that have been approved
for Mercedes-Benz vehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or
systems could be damaged.
Before changing a fuse
XPark the vehicle and apply the parking
brake.XSwitch off all electrical consumers.XRemove the key from the ignition lock.
The fuses are located in various fuse boxes:
R fuse box on the front-passenger side of the
dashboard
R fuse box in the engine compartment on the
right-hand side of the vehicle, when viewed
in the direction of travel
R fuse box in the cargo compartment on the
right-hand side of the vehicle, when viewed
in the direction of travel
The fuse allocation chart is located in the
vehicle tool kit ( Y page 310) in the stowage
compartment under the trunk floor.

! Do not use a pointed object such as a
screwdriver to open the cover in the
dashboard. You could damage the
dashboard or the cover.
XTo open: pull cover : outwards in the
direction of the arrow and remove it.XTo close: clip in cover : on the front of

the use of gasoline or kerosene is not
covered by the Mercedes-Benz Limited
Warranty.
To prevent malfunctions, diesel fuel with
improved flow characteristics is available in
the winter months. Check with your fuel
retailer.
Information on the fuel grade can usually be
found on the gas pump. If the information
cannot be found on the gas pump, ask service
station personnel. For further information,
contact an authorized Mercedes-Benz Center
or visit http://www.mbusa.com (USA
only).
Diesel engines – Fuels containing bio-
diesel (FAME [fatty acid methyl ester])
Mercedes-Benz USA approves the use of B5
(ULSD with a maximum of up to five percent
by volume biodiesel) for all diesel engines
with common rail direct injection (CDI) and
BlueTEC.
Pure biodiesel and diesel fuels that contain a
higher percentage of biodiesel, e.g. B20, may
cause damage to the fuel system/engine and
are, therefore, not approved.
For further information, please ask the
service station personnel. The label on the
gas pump must indicate clearly that the B5
biodiesel blend meets the ULSD standard. If
the label is not clear, do not refuel the vehicle.
The Mercedes-Benz Limited Warranty does
not cover damages caused by the use of fuels
not meeting Mercedes-Benz approved fuel
standards.
Additives in gasoline
One of the major problems in engine design
is the creation of carbon deposits during the
process of burning fuel. Mercedes-Benz
recommends that you use fuel brands that
have the additives which prevent the build up
of carbon deposits.
If you use fuels without these additives for a
longer period of time, there may be a build up
of carbon deposits, especially on the inlet
valves and in the combustion chamber.
This could lead to engine running problems,
e.g.:
R warm-up hesitation
R unstable idle
R knocking/pinging
R misfire
R power loss
In areas where carbon deposits may be
encountered due to lack of availability of
gasoline which contains these additives,
Mercedes-Benz recommends the use of
additives approved for use in Mercedes-Benz
vehicles.
Consult an authorized Mercedes-Benz Center
or visit http://www.mbusa.com (USA only)
to view a list of approved products. Observe
the instructions for use on the product label.
Do not mix other fuel additives with fuel. This
causes unnecessary costs and could damage
the engine.
! Do not refuel with low-grade fuel and do
not use fuel additives that are not tested
and approved for Mercedes-Benz vehicles.
Damage or malfunctions can result that are
not covered:
R by the Mercedes-Benz Limited Warranty
R by an existing Limited Warranty
R by an extended Limited Warranty
AdBlue ®
Important safety guidelines
i For BlueTEC vehicles only.
AdBlue ®
is a non-flammable, non-toxic,
colorless, odorless and water-soluble fluid.
! Only use AdBlue ®
that complies with
ISO 22241. Do not add any special
additives to AdBlue ®
and do not thin
AdBlue ®
with water. This could destroy the
BlueTEC exhaust gas aftertreatment.

! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants and on
filling 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 an authorized Mercedes-
Benz Center.
! Always use a suitable 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 the coolant has antifreeze protection down
to -35 ‡ (-37 †), the boiling point of the
coolant in the pressurized system is
approximately 266 ‡ (130 †).
Your vehicle has a range of aluminum
components. Use of aluminum components
in the engine make it necessary to specifically
match the antifreeze/corrosion inhibitor in
these systems in order to protect the
aluminum parts. Using other antifreeze/
corrosion inhibitors without these
characteristics affects the service life.
The coolant must be used throughout the year
in order to maintain the necessary corrosion
protection and provide protection from
overheating. In the Service Booklet, you can
find information on the intervals for renewal.
The renewal interval is determined by the
coolant type and the cooling system design.
The renewal interval in the Service Booklet is
only valid if the coolant is added or renewed
with Mercedes-Benz approved products.
Therefore, only use MB 326.0 antifreeze/
corrosion inhibitor or another Mercedes-Benz
approved product of the same specification.
Information on other Mercedes-Benz
approved products of the same specification
can be obtained at any authorized Mercedes-
Benz Center or on the Internet at
http://bevo.mercedes-benz.com .The coolant is checked at every service date
at an authorized Mercedes-Benz Center.
The antifreeze/corrosion inhibitor
concentration in the cooling system should:
R be at least 50%. This will protect the cooling
system against freezing down to around
-35 ‡ (-37 †).
R not exceed 55% (antifreeze protection
down to -49 ‡ (-45 †); otherwise, heat will
not be dissipated as effectively.
If the coolant level is too low, MB 326.0
antifreeze/corrosion inhibitor should be
added. Have the cooling system checked for
leaks.

GWarning
Washer solvent/antifreeze is highly
flammable. Do not spill washer solvent/
antifreeze on hot engine parts, because it may
ignite and burn. You could be seriously
burned.
