out delay.
RIf fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-

RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic buildup can create sparks and
ignite fuel vapors. There is a risk of fire and
explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existing electrostatic buildup is
thereby discharged.
Do not get into the vehicle again during the refu-
eling process. otherwise electrostatic charge
could build up again.
GWARNING
Vehicles with a diesel engine:
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.
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the ignition
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 qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.

Even small amounts of the wrong fuel could

!Overfilling the fuel tank could damage the
fuel system.
!Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
!Use a filter when adding fuel from a fuel can.
The fuel lines and/or the fuel injection system
could otherwise be blocked by particles from
the fuel can.
If you overfill the fuel tank, fuel could spray out
when the fuel pump nozzle is removed.

General information
Pay attention to the important safety notes
(Ypage 143).
If you unlock/lock the vehicle from the outside,
the fuel filler flap also unlocks/locks.
The position of the fuel filler cap is displayed in
the instrument cluster 8. The arrow next to
the filling pump indicates the side of the vehicle.

When the DEF supply drops to a minimum, the
Remaining Starts: 16message is shown in
the multifunction display.
The Remaining Starts: 16
message in the
multifunction display indicates how many more
times you can start the vehicle. If DEF is not
refilled, you will subsequently be unable to
start the engine.
If the 10 starts display message is shown and a
warning tone also sounds, then the DEF system
is malfunctioning. Have the DEF system
checked at a qualified specialist workshop.
XAdd at least 1.3 gal (5.0 l) of DEF.
XSwitch on the ignition for at least 60 seconds.
XStart the engine.
iHave the DEF tank refilled at a qualified spe-
cialist 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 28).
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 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
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 experi-
ence 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:
RRinse DEF from your skin immediately with
soap and water.
RIf DEF comes into contact with your eyes,
immediately rinse them thoroughly with clean
water. Seek medical assistance without
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
ISO 22241. Do not mix any additives with
DEF, and do not dilute DEF with water. This
may destroy the BlueTEC exhaust gas after-
treatment 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 overfil
ling, 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 crys-
tallize after time and contaminate the affec-
ted 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.
Have the DEF tank refilled at a qualified special-
ist workshop. However, you can also refill the
DEF tank:
Rat a gas station with a DEF filling pump
Rwith DEF refill bottles
Rwith a DEF refill canister
When the pump nozzle switches off automati-
cally during filling at a filling pump, the DEF tank
has been completely filled. Do not fill the DEF
tank any further. DEF may leak out.

!Do not operate the tire inflation compressor
for longer than ten minutes at a time without
a break. It may otherwise overheat.
The tire inflation compressor can be operated
again once it has cooled down.
Comply with the manufacturer’s safety instruc-
tions on the sticker on the tire inflation com-
pressor.
Using the TIREFIT kit
XDo not remove any foreign objects which have
penetrated the tire, e.g. screws or nails.
XRemove the tire sealant bottle, the accompa-
nying TIREFIT sticker and the tire inflation
compressor from the stowage well under-
neath the cargo compartment floor
(
Ypage 314).
XAffix part :of the TIREFIT sticker to the

XInsert plug ?into cigarette lighter socket
(Ypage 287) or into another 12 V socket in
your vehicle (Ypage 287).
XTurn the SmartKey to position 1in the igni-
tion lock (Ypage 127).
XPress on and off switch =on the tire inflation
compressor.
The tire inflation compressor is switched on.
The tire is inflated.
First, tire sealant is pumped into the tire. The
pressure may briefly rise to approximately
500 kPa (5 bar/73 psi).
Do not switch off the tire inflation com-
pressor during this phase.
XLet the tire inflation compressor run for a
maximum of ten minutes. The tire should then
have attained a pressure of at least 200 kPa
(2.0 bar/29 psi).
If a pressure of 200 kPa (2.0 bar/29 psi) has
been attained after five minutes, see "Tire pres-
sure reached" (
Ypage 318).
If a tire pressure of 200 kPa (2.0 bar/29 psi) has
not been attained after five minutes, see "Tire
pressure not reached" (
Ypage 318).
If tire sealant has escaped, clean it off affected
areas as quickly as possible. Use plain water if
possible.
