Problems with fuel and the fuel tank
This section provides descriptions of and solutions to safety-relevant problems. Descriptions
of and solutions to further problems can be found in the Digital Operator's Manual.
ProblemPossible causes/consequences and MSolutions
Fuel is leaking from the
vehicle.GWARNING
The fuel line or the fuel tank is faulty.
Risk of explosion or fire.
XApply the electric parking brake.
XSwitch off the engine.
XRemove the SmartKey from the ignition lock.
or, on vehicles with KEYLESS‑GO:
XOpen the driver's door.
The on-board electronics now have status 0. This is the same as
the SmartKey having been removed.
XDo not restart the engine under any circumstances.
XConsult a qualified specialist workshop.
DEF (BlueTEC vehicles only)
Important notes on use
To function properly, BlueTEC exhaust gas
aftertreatment must be operated with the
reducing agent DEF. Adding DEF is one of the
tasks performed during maintenance. Under
normal operating conditions, a tank of DEF
lasts until the next service due date.
When the supply of DEF is almost used up, the
Check
AdditiveSeeOperator'sManual
message is shown in the multifunction dis-
play.
When the DEF supply drops to a minimum, the
Remaining Starts: 16
message is shown
in the multifunction display.
If the Remaining Starts: 16
message
appears in the multifunction display, you can
start the engine another 16 times. If DEF is
not refilled, you will subsequently be unable
to start the engine.
XAdd at least 1 gal (3.8 l)of DEF.
XSwitch on the ignition for at least 60 sec-
onds.
XStart the engine.
iHave the DEF tank refilled at a qualified
specialist workshop.
Use the special DEF refill bottle when adding
DEF between maintenance intervals. Contact
an authorized Mercedes-Benz Center with
any questions or, if necessary, contact Road-
side Assistance (
Ypage 29).
If the outside temperature is below 12 ‡
(Ò11 †) it may be difficult to top up. If DEF is frozen and there is an active warning indica-
tor, it may not be possible to add DEF. Park
the vehicle in a warmer place, e.g. in a garage,
until DEF has become fluid again. It will then
be possible to add DEF again. Alternatively,
have the DEF tank refilled at a qualified spe-
cialist workshop.
Further information about BlueTEC exhaust
gas aftertreatment and DEF is available at any
authorized Mercedes-Benz Center.

Important notes on topping up
DEFisa water-soluble fluid for the exhaust
gas aftertreatment of diesel engines. Itis:
Rnot pois onous
Rcolorless and odorless
Rnot flammable
When you open the DEF container, small
amounts of ammonia vapor may be released. Ammon iavapors have a pungent odor and are
particularly irr itating to the skin, to mucous
membranes and to the eyes. You may expe-
rience a burning sensation in your eyes, nose and throat. Coughing and watering of the
eyes are possible.
Do not inhale ammonia vapors. Fill the DEF
tank only in well- ventilated areas.
DEF must not come into contact with your
skin, eyes or clothing and must not beswal-
lowed. Keep DEF away from children.
If you or other persons come into contact with
DEF, observe the fol lowing:
RRinse DEF from your skin immediatelywith
soap and water.
RIf DEF comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
RIf DEF has been swallowed,rinse your
mouth out immediately. Drink plenty of
water. Seek medical assistance without
delay.
RChange out of clothing contaminated with
DEF immediately.
!Only use DEF in accordance with
IS O 22241. Do not mix any additives with
DEF, and donot dilute DEF with water. This
may destroy th e B
lueTEC exhaust gas after-
treatment system.
!Rins e surfaces that have come into con-
tact with DEF immediately with water or
remove DEF using a damp cloth and co ld
water. Ifthe DEF has already crystallized,
use a sponge and co ldwater to clean it. DEF residues crystallize after time and contam-
inate the affected surfaces.
!DEF
isnot a fuel additive and must not be
added to the fuel tank. IfDEF isadded to
the fuel tank, th iscan lead to engine dam-
age.
!Only screw on the DEF ref illbottle hand-
tight. Itcould otherwise bedamaged.

Gasoline
Fuel grade
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the igni-
tion 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 quali-
fied 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. Operat-
ing 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 addi-
tives for the removal and prevention of res- idue build-up. Gasoline may only be mixed
with cleaning additives recommended by
Mercedes-Benz; see "Additives". You can
obtain further information from any author-
ized Mercedes-Benz Center.
!To ensure the longevity and full perform-
ance of the engine, only premium-grade
unleaded gasoline must be used.
338Service products and filling capacities
Technical data
If standard unleaded gasoline is unavaila-
ble and you have to refuel with unleaded
gasoline of a lower grade, observe the fol-
lowing precautions:
ROnly fill the fuel tank to half full with reg-
ular unleaded gasoline and fill the rest
with premium-grade unleaded gasoline
as soon as possible.
RDo not drive at the maximum speed.
RAvoid sudden acceleration and engine
speeds over 3,000 rpm.
You will usually find information about the fuel
grade on the pump. If you cannot find the
label on the pump, ask the staff for assis-
tance.
iFor further information, consult a quali-
fied specialist workshop or visit
http://www.mbusa.com (USA only).
iE10 fuel contains up to 10% bioethanol.
Your vehicle is E10-compatible. You can
refuel your vehicle using E10 fuel.
As a temporary measure, if the recommended
fuel is not available, you may also use regular
unleaded gasoline with an octane rating of
87 AKI/91 RON. This may reduce engine per-
formance and increase fuel consumption.
Avoid driving at full throttle and sudden accel- eration. Never refuel using fuel with a lower
AKI.
Information on refueling (
Ypage 146).
Additives
!Operating the engine with fuel additives
added later can lead to engine failure. Do
not mix fuel additives with fuel. This does
not include additives for the removal and
prevention of residue buildup. gasoline
must only be mixed with additives recom-
mended by Mercedes-Benz. Comply with
the instructions for use on the product
label. More information about recommen-
ded additives can be obtained from any
authorized Mercedes-Benz Center.
Mercedes-Benz recommends that you use
branded fuels that have additives. The quality of the fuel available in some coun-
tries may not be sufficient. Residue could
build up in the injection system as a result. In
such cases, and in consultation with an
authorized Mercedes-Benz Center, the gaso-
line may be mixed with the cleaning additive
recommended by Mercedes-Benz.
You mu
st
observe the notes and mixing ratios specified
on the container.
Diesel
Fuel grade
GWARNING
If you mix diesel fuel with gasoline, the flash
point is lower than that of pure diesel fuel.
When the engine is running, exhaust system
components could overheat without being
noticed. There is a risk of fire.
Never refuel with gasoline. Never mix gasoline with diesel fuel.
!Only use commercially available vehicular
ULTRA-LOW SULFUR DIESEL FUEL (ULSD,
15 ppm maximum sulfur content) that
meets the ASTM D975 standard. If you do
not refuel with ULSD, you may damage the
BlueTEC exhaust gas aftertreatment sys-
tem of the vehicle.
!Do not use gasoline to refuel vehicles with
a diesel engine. Do not mix diesel fuel with
gasoline, kerosene or paraffin. This may
otherwise result in damage to the fuel sys- tem and engine.
You will usually find information about the fuel grade on the pump. If you cannot find the
label on the pump, ask the staff for assis-
tance.
