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,
theCheck Additive See Operator'sCheck Additive See Operator's
ManualManualmessage is shown in the
multifunction display.
If you drive the vehicle faster than 10 mph
(16 km/h), theCheck Additive SeeCheck Additive See
Operator'sOperator'sManualManualmessage goes out after
approximately one minute.
When the supply of DEF is down to a reserve
of approximately 1 gal (3.8 l) theRefillRefill
AdBlue/DEF See Operator's ManualAdBlue/DEF See Operator's Manual
message is shown in the multifunction
display.
When the DEF supply drops to a minimum, the
Remaining Starts: 16Remaining Starts: 16message is shown
in the multifunction display.
If theRefill AdBlue/DEF No Start inRefill AdBlue/DEF No Start in
XXXX kmXXXX kmmessage is shown in the
multifunction display, you can still drive the
vehicle over the distance shown. If DEF is not
refilled, you will subsequently beunable to
start the engine. If theRefill AdBlue/Refill AdBlue/
DEF Eng. Start Not PossDEF Eng. Start Not Possmessage
appears in the multifunction display and the
engine does not start, you must add DEF.
XAdd at least 1 gal(3.8l) of DEF.
XSwitch on the ignition for at least 60
seconds.
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
Roadside Assistance (Ypage 25).
If the outside temperature is below 12 ‡
(

water. Seek medical assistance without
delay.
RChange 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.
!The vehicle must be parked on level
ground to fill the DEF tank. The DEF tank
can only be filled as intended with the
vehicle parked on a level surface. This
avoids false level readings. Filling the tank
is not permitted if the vehicle is not parked
on a level surface. There is a danger of
overfilling, which could result in damage to
components of the BlueTEC exhaust gas
aftertreatment.
!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
residues crystallize after time and
contaminate the affected surfaces.
!DEF is not a fuel additive and must not be
added to the fuel tank. If DEF is added to
the fuel tank, this can lead to engine
damage.
For further information on DEF, see
(Ypage 448).
You will find further information on DEF in the
printed Operator's Manual under "Technical
data".

!Do not use the following:
Rmarine diesel
Rheating oil
Rbio-diesel
Rvegetable oil
Rgasoline
Rparaffin
Rkerosene
Do not mix such fuels with diesel fuel and
do not use any special additives. This can
otherwise lead to engine damage.
!Vehicles with diesel particle filters:in
countries outside the EU, only use low
sulfur Euro diesel with a sulfur content of
under 50 ppm. Otherwise, the emission
control system could be damaged.
!Vehicles without a diesel particle
filter:in countries where only diesel fuel
with a high sulfur content is available, you
will need to carry out your vehicle's oil
change at shorter intervals. Further
information on oil change intervals can be
obtained at a qualified specialist workshop.
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.
Information on refueling (Ypage 183).
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 (Ypage 183).
Low outside temperatures
iDiesel 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.
DEF
Important safety notes
Comply with the important safety notes for
service products when handling DEF
(Ypage 445).
DEF is a water-soluble fluid for the exhaust
gas aftertreatment of diesel engines. It is:
Rnot poisonous
Rcolorless and odorless
Rnot 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:
Rincreased emission values
Rdamage to the catalytic converter
Rengine damage
Rmalfunctions 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.

Engine oil
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
(Ypage 445).
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
Center. Or visit the website
