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 Additive See Operator's
Manual message is shown in the
multifunction display.
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 . Refill the DEF tank with
around 1 gal (3.8 l) of DEF or have the DEF
tank refilled at a qualified specialist
workshop.
Use the special DEF refill bottle when adding
DEF between maintenance intervals. Contact
a qualified specialist workshop with any
questions or, if necessary, contact Roadside
Assistance ( Y page 24).
If the outside temperature is below 12 ‡
(00FC11 †) it may be difficult to top up. If DEF is
frozen and there is an active warning
indicator, 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 specialist workshop.
Further information about BlueTEC exhaust
gas aftertreatment and DEF is available at any
authorized Mercedes-Benz Center. Important safety notes on the refilling
procedure DEF is a water-soluble fluid for the exhaust
gas aftertreatment of diesel engines. It is:
R
not poisonous
R colorless and odorless
R not flammable
When you open the DEF container, small
amounts of ammonia vapor may
be released.
Ammonia vapors have a pungent odor and are
particularly irritating to the skin, to mucous
membranes and to the eyes. You may
experience 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 be
swallowed. Keep DEF away from children.
If you or other persons come into contact with
DEF, observe the following:
R Rinse DEF from your skin immediately with
soap and water.
R If DEF comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance
without delay.
R If DEF has been swallowed, rinse your
mouth out immediately. Drink plenty of
water. Seek medical assistance without
delay.
R Change out of clothing contaminated with
DEF immediately.
! Only use DEF in accordance with
ISO 22241. Do not mix any additives with
DEF, and do not dilute DEF with water. This
may destroy the BlueTEC exhaust gas
aftertreatment system.
! Rinse surfaces that have come into
contact with DEF immediately with water or
remove DEF using a damp cloth and cold
water. If the DEF has already crystallized,
use a sponge and cold water to clean it. DEF 158

Technical data

One of the main problems of poor fuel quality
is the forming of deposits that are created
during the gasoline combustion process.
Mercedes-Benz recommends that you use
branded fuels that have additives.
If you use fuels without these additives over
a longer period of
time,
carbon deposits may
build up. These deposits form at the inlet
valves and in the combustion chamber in
particular.
This could lead to engine problems, e.g.:
R longer engine warm-up phase
R uneven idle
R engine noise
R misfiring
R loss of power
Carbon deposits may form if the availability
of gasoline with relevant additives is
insufficient (in certain regions). In this case,
Mercedes-Benz recommends additives
approved for use in Mercedes-Benz vehicles;
see http://bevo.mercedes-benz.com.
For a list of approved products, consult an
authorized Mercedes-Benz Center. Comply
with 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.
Diesel Fuel grade
G
WARNING
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
system 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
system 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
assistance.
i For further information, consult a
qualified specialist workshop or on the
Internet at http://www.mbusa.com (USA
only).
Information on refueling (Y page 154).
Bio-diesel - FAME (fatty acid methyl ester)
Mercedes-Benz USA approves the use of bio-
diesel B5 for all BlueTEC diesel engines. The
concentration of bio-diesel in the ULSD may
not exceed 5% by volume.
Pure bio-diesel and diesel fuel with a higher
percentage of bio-diesel, such as B20, can
damage the engine and the fuel system. For
this reason, they are not approved.
For more information, consult the gas station
staff. The bio-diesel B5 label on the gasoline
pump must clearly state that the standard for
ULSD has been fulfilled. If the label is not
clear, do not refuel the vehicle.
Do not refuel your vehicle with fuels unless
they have been approved by Mercedes-Benz.
Information on refueling (Y page 155).
Low outside temperatures
i Diesel fuel with improved cold flow
properties is available during the winter
months. Further information about fuel
properties can be obtained from oil
companies, e.g. at gas stations. 368

DEF
Important safety notes Comply with the important safety notes for
service products when handling DEF
(Y page 365).
DEF is a water-soluble fluid for the exhaust
gas aftertreatment of diesel engines. It is:
R
not poisonous
R colorless and odorless
R not flammable
When you open the DEF container, small
amounts of ammonia vapor may
be released.
Ammonia vapors have a pungent odor and are
particularly irritating to the skin, to mucous
membranes and to the eyes. You may
experience 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.
Low outside temperatures DEF freezes at a temperature of
approximately
12 ‡ (-11
†). The vehicle is
delivered from the factory equipped with a
DEF preheating
system.

Winter operation can
thus be guaranteed even at temperatures
below 12 ‡ (-11 †).
Additives !
Only use DEF in accordance with ISO
22241. Do not use additives with DEF and
do not dilute DEF with water. This may
destroy the BlueTEC exhaust gas
aftertreatment system.
Purity !
Impurities in DEF (e.g. due to other
service products, cleaning agents or dust)
lead to:
R increased emission values
R damage to the catalytic converter R
engine damage
R malfunctions in the BlueTEC exhaust

gas
aftertreatment system
Assuring the purity of DEF is particularly
important with respect to avoiding
malfunctions in the BlueTEC exhaust gas
aftertreatment system.
If DEF is pumped out of the DEF tank, e.g.
during repair work, it must not be returned to
the tank. The purity of the fluid can no longer
be guaranteed.

General notes !
Never use engine oil or an oil filter of a
specification other than is necessary to
fulfill the prescribed service intervals. Do
not change the engine oil or oil filter in
order to achieve longer replacement
intervals than those prescribed. You could
otherwise cause engine damage or

damage
to the exhaust gas aftertreatment.
Follow the instructions in the service
interval display regarding the oil change.
Otherwise, you may damage the engine and
the exhaust gas aftertreatment.
When handling engine oil, observe the
important safety notes on service products
(Y page 365).
The engine oils are matched to the
performance of Mercedes-Benz engines and
service intervals. You should therefore only
use engine oils and oil filters that are
approved for vehicles with maintenance
systems.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz Service products and filling capacities
