DEF (BlueTEC vehicles only)
Important notes on use To function properly, BlueTEC exhaus
tgas
aftertreatment must be operated with the
reducing agen tDEF. 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 almos tused up,
the Check Additive See Operator's Manual message is shown in the
multifunction display.
When the DEF supply sinks to a minimum
level, 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 added, it will then not be possible to
restart the engine. Refill the DEF tank with
approximately 1gal(3.8 l)of DEForh ave the
DE Ftank refilled at a qualified specialist
workshop.
Use the special DE Frefill bottle when filling
between maintenance intervals. Contact a
qualified specialist workshop with any
questions or, if necessary, contact Roadside
Assistance (Y page 22).
If the outside temperature is lower than
12 ‡ (Ò11) †, damage may occur when
adding DEF. 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 DEFh as
become fluid again .Itwill the nbe possible to
add DEF again. Alternatively, have the DEF
tank refilled at a qualified specialist
workshop.
Further information about BlueTEC exhaust
gas aftertreatmen tand DEF is available at any
authorized Mercedes-Benz Center. Important notes on topping up G
WARNING
Make sure
R DEF does not come into contact with skin,
eyes, or clothing
R to keep DEF out of the reach of children
If you and/or others have come into contact
with DEF:
R If DEF has gotten into contact with eyes,
flush with plenty of water immediately and
see km edical help.
R Clean affected skin immediately with plenty
of water.
R If DEFw as swallowed, rinse mouth
immediately with plenty of wate rand drink
plenty of water. Consult a physician. G
WARNING
If you open the DEF tank cap, small amounts
of ammonia vapor may be released .This
depends in particular upon the age of the DEF.
Ammonia vapors have a pungent odor and are
particularly irritating to:
R skin
R mucous membranes
R eyes
You may experience a burning sensation in
your eyes, nose and throat, as well as
coughing and watering of the eyes.
Do not inhale any ammonia vapors that may
be released. Fill the DEF tank only in well-
ventilated areas.
! 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 164
RefuelingDriving and parking

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.
! Only screw on the DEF refill bottle hand-
tight. It could otherwise be damaged.
The DEF filler neck is under the cargo
compartment floor.
X Switch the ignition off.
X Open the tailgate.
X Lift up the cargo compartment floor
(Y page 298). X
Remove lug wrench ;and ratchet wrench
=, if present.
X Turn DEF cap :counter-clockwise and
remove it. X
Turn DEF filler cap ?counter-clockwise
and open it.
Filler cap ?is secured with a plastic strip. X
Unscrew the protective cap from DEF refill
bottle A.
X Position DEF refill bottle Aas show non
the filler neck and screw it on hand-tight.
X Press DEF refill bottle Adownwards.
The DEF tank is filled .This may take up to
one minute.
i To add between service intervals, fill the
DEF tank with approximately 1gal (3. 8l) of
DEF. 1 gal (3.8 l) of DEF is equivalent to
approximately 2DEF refill bottles. Then
have the DEF supply checked at a qualified
specialis tworkshop and completely refilled
if necessary.
X Release DEFr efill bottleA.
When DEFr efill bottleAis no longer
pressed down, filling stops. DEFr efill bottle
A can be removed when it has been only
partially emptied.
X Turn DEFr efill bottle Acounter-clockwise
and remove it.
X Place DEFf iller cap?on the filler necka nd
turn it clockwise. Refueling

Never exceed the maximum permissible tire
inflation pressure. Always observe the
recommended tire pressure for yourv
ehicle
when adjusting the tire pressure
(Y page 316).
i The actual values for tires are vehicle-
specific and may deviate from the values in
the illustration. Checking the tire pressures
Important safety notes Observe the notes on tire pressure
(Y
page 316).
Information on air pressure for the tires on
your vehicle can be found:
R on the vehicle's Tire and Loading
Information placard loading information
table on the B-pillar (Y page 323)
R on the tire pressure label on the fuel filler
flap
R in the "Tire pressure" section
R under "Tire pressure" (Y page 316)
Checking tire pressures manually To determine and set the correct tire
pressure, proceed as follows:
X
Remove the valve cap of the tire that is to
be checked.
X Press the tire pressure gauge securely onto
the valve.
X Read the tire pressure and compare it with
the recommended value on the Tire and
Loading Information placard (Y page 316).
X If the tire pressure is too low, increase it to
the recommended value.
X If the tire pressure is too high, release air
by pressing down the metal pin in the valve.
Use the tip of a pen, for example. Then,
chec kthe tire pressure again using the tire
pressure gauge.
X Screw the valve cap onto the valve.
X Repeatt hese steps for the other tires. Tire pressure loss warning system
(Canada only)
Important safety notes While the vehicle is in motion, the tire
pressure loss warning system monitors the
set tire pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in a tire. If the speed
of rotation of a wheel changes as a result of
a loss of pressure, a corresponding warning
message will appearint
he multifunction
display.
The tire pressure warning system does not
warn you of an incorrectly set tire pressure.
Observe the notes on the recommended tire
pressure (Y page 316).
The tire pressure loss warning system does
not replace the need to regularly check your
vehicle's tire pressures, since an even loss of
pressure on several tires at the same time
cannot be detected by the tire pressure loss
warning system.
The tire pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tire is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Avoid
abrupt steering maneuvers.
The function of the tire pressure loss warning
system is limited or delayed if:
R snow chains are mounted to your vehicle's
tires.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt a very sporty driving style
(cornering at high speeds or driving with
high rates of acceleration).
R you are towing a very heavy or large trailer.
R you are driving with a heavy load (in the
vehicle or on the roof). Tire pressure

Pure biodiesel and diesel fuel with a higher
percentage of biodiesel, 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 160).
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.
Flow improver
To improve the low-temperature resistance of
diesel fuel, a flow improver can be attached.
The effectiveness of a flow improver is not
guaranteed for every fuel.
Only use flow improvers tested and approved
by Mercedes-Benz.D uringuse, please
observe the information on operation.
Correct dosage and sufficient mixing are
decisive in improving low-temperature
resistance with the flow improver.
Overdosage can potentially even decrease
low-temperature resistance and must
therefore be avoided.F ollow the
manufacturer's guidelines on dosage.
Mix the additive into the diesel in good time,
before the flow characteristics of the diesel
become insufficient. Otherwise, malfunctions
can arise through heating the fuel system,
e.g. through parking in a heated garage.
More information about recommended flow
improvers can be obtained from any qualified
specialist workshop. DEF
