If you or others come into contact with fuel,
observe the following:
R
Wash away fuel from skin immediately
using soap and water.
R If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance
without delay.
R If fuel is swallowed, seek medical
assistance without delay. Do not induce
vomiting.
R Immediately change out of clothing which
has come into contact with fuel. G
WARNING
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. G
WARNING
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 gasoline to refuel vehicles with
a diesel engine. 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.
The repair costs are high. Notify a qualified
specialist workshop and have the fuel tank
and fuel lines drained completely. !
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 refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
If you overfill the fuel tank, fuel could spray
out when the fuel pump nozzle is removed.

To open
X
Switch the engine off.
X Remove the SmartKey from the ignition
lock.
X KEYLESS-GO: open the driver’s door.
This corresponds to key position 0: "key
removed".
The driver’s door can be closed again.
X Press the fuel filler flap in the direction of
arrow 0043.
The fuel filler flap opens slightly.
X Open the fuel filler flap fully.
X Turn the fuel filler flap counter-clockwise
and remove it.
X Insert the fuel filler cap into the holder
bracket on the inside of filler flap 0044.
X Completely insert the filler neck of the fuel
pump nozzle into the tank, hook in place
and refuel.
X Only fill the tank until the pump nozzle
switches off.
i Do not add any more fuel after the pump
stops filling for the first time. Otherwise,
fuel may leak out.
To close X
Replace the cap on the filler neck and turn
clockwise until it engages audibly.
X Close the fuel filler flap.
i Close the fuel filler flap
before locking the
vehicle.
i If you are driving with the fuel filler cap
open, the 00B6 reserve fuel warning lamp
flashes. A message appears in the
multifunction display ( Y page 245).
In addition, the 00B9 Check Engine warning
lamp may light up ( Y page 264).

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

Unscrew the protective cap from DEF refill
bottle 0087.
X Set DEF refill bottle 0087 as shown on the
filler neck and screw it on hand-tight.
X Press DEF refill bottle 0087 downward.
The DEF tank is filled. This may take up to
one minute.
i To top up between service intervals, fill
the DEF tank with approximately 1 gal
(3.8 l) of DEF.
1

gal (3.8 l) DEF is equivalent
to approximately 2 DEF refill bottles. Then
have the DEF supply checked at a qualified
specialist workshop and completely refilled
if necessary.
X Release DEF refill bottle 0087.
When DEF refill bottle 0087 is no longer
pressed down, filling stops.
DEF

and remove it.
X Place DEF filler cap 0044 on
the filler
neck
and
turn it clockwise. Refueling

Driving and parking Z

The vehicle/trailer combination:
R
is heavier
R is restricted in its acceleration and
gradient-climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R has a larger turning radius
This could impair the handling
characteristics.
When towing a trailer, always adjust your
speed to the current road and weather
conditions. Do not exceed the maximum
permissible speed for your vehicle/trailer
combination.
General notes R
Do not exceed the legally prescribed
maximum speed for vehicle/trailer
combinations in the relevant country.
This lowers the risk of an accident.
R Only install an approved trailer
coupling on
your vehicle.
Further information on availability and on
installation is available from any authorized
Mercedes-Benz Center.
R The bumpers of your vehicle are not
suitable for installing detachable trailer
couplings.
R Do not install hired trailer couplings or
other detachable trailer couplings on the
bumpers of your vehicle.
R To reduce the risk of damage to the ball
coupling, remove it from the ball coupling
recess when not in use.
i When towing a trailer, set the tire
pressure on the rear axle of the towing
vehicle for a maximum load; see the tire
pressure table in the fuel filler flap
(Y page 349).
You will find installation dimensions and loads
in the "Technical data" section
(Y page 374). Missing values for the maximum noseweight
of the trailer drawbar on the ball coupling
were
unavailable at
the time

of going to print.
However, the actual noseweight must not
exceed the value given on the identification
plates of the trailer tow hitch and trailer. The
lowest weight applies.
Please note that when towing a trailer,
PARKTRONIC ( Y page 180) is only available
with limitations or not at all.
i On vehicles without level control, the
height of the ball coupling will alter
according to the load placed on the vehicle.
If necessary, use a trailer with a height-
adjustable drawbar.
Driving tips i
Observe the notes on ESP ®
trailer
stabilization ( Y page 69).
The maximum permissible speed for

vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check
the trailer's documents to see what the
maximum permissible speed is. Observe the
legally prescribed maximum speed in the
relevant country.
For certain Mercedes-Benz vehicles, the
maximum permissible rear axle load is
increased when towing a trailer. Refer to the
"Technical data" section to find out whether
this applies to your vehicle.
If you utilize any of the added maximum rear
axle load when towing a trailer, the vehicle/
trailer combination may not exceed a
maximum speed of 60 mph (100 km/h) for
reasons concerning the operating permit.
This also applies in countries in which the
permissible maximum speed for vehicle/
trailer combinations is above 60 mph
(100 km/h).
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
with when driving without a trailer.
On long and steep downhill gradients, you
must select shift range 1, 2 or 3 in good time. Towing a trailer
