!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 sys-
tem could be blocked by particles from the
fuel can.
If you overfill the fuel tank, pressure may build
up in the fuel tank. This could cause fuel to spray
out when the fuel pump nozzle is removed.
There is a risk of injury. The fuel tank is full when
the fuel pump nozzle first switches off. End the
refueling process.
For further information on fuel and fuel quality
(
Ypage 289).

XRemove the SmartKey from the ignition lock.
XTurn the fuel filler cap counterclockwise and
remove it.
XInsert the fuel filler cap into the holder
bracket on the inside of filler flap ?.
Refueling
XCompletely insert the filler neck of the fuel
pump nozzle into the tank and refuel.
iDo not add any more fuel after the pump
stops filling for the first time. Otherwise, fuel
may leak out.
Closing
XReplace the fuel filler cap and turn it clock-
wise. The fuel filler cap audibly engages.
XClose the fuel filler flap.
iClose the fuel filler flap before locking the
vehicle. A locking pin otherwise prevents the
fuel filler flap from closing after the vehicle
has been locked.
128Refueling
Driving and parking

Always install and secure the ball coupling asdescribed. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter.
Please observe the manufacturer's operating
instructions for the trailer coupling if a detach-
able trailer coupling is used.
Exceeding the maximum permissible nose-
weight may cause damage to the following:
Ryour vehicle
Rthe trailer
Rthe ball coupling
Rtrailer tow hitch
The vehicle/trailer combination could become
unstable.
If the noseweight used is lower than the mini-
mum permissible noseweight, the vehicle/
trailer combination could also become unstable.
To avoid hazardous situations:
Rmake sure to check the noseweight before
each journey
Ruse a drawbar noseweight as close as possi-
ble to the maximum noseweight
Rdo not exceed the maximum permissible
noseweight
Rdo not use a noseweight lower than the min-
imum permissible trailer drawbar noseweight
When backing up the vehicle towards the trailer,
make sure there is nobody between the trailer
and the vehicle.
The applicable permissible values, which must
not be exceeded, can be fou nd:
Rin your vehicle documents
Ron the type plate of the trailer tow hitch and
trailer
Ron the vehicle identification plate
Couple and uncouple the trailer carefully. If you
do not couple the trailer to the towing vehicle
correctly, the trailer could become detached.
Make sure that the following values are not
exceeded:
Rthe permissible trailer drawbar noseweight
Rthe permissible trailer load
Rthe permissible rear axle load of the towing
vehicle
Rthe maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer When towing a trailer, your vehicle's handling
characteristics will be different in comparison
with when driving without a trailer.
The vehicle/trailer combination:
Ris heavier
Ris restricted in its acceleration and gradient-
climbing capability
Rhas an increased braking distance
Ris affected more by strong crosswinds
Rdemands more sensitive steering
Rhas a larger turning radius
This could impair the handling characteristics.
Adapt your driving style accordingly. Maintain a
safe distance. Drive carefully.
When towing a trailer, always adjust your speed
to the current road and weather conditions. Do
not excee
d the maximum permissible speed for
your vehicle/trailer combination.
You will find the values approved by the manu-
facturer on the vehicle identification plates and
those for the towing vehicle in the "Technical
data" section (
Ypage 297).
General notes
RDo not exceed the legally prescribed maxi-
mum speed for vehicle/trailer combinations
in the relevant country.
This lowers the risk of an accident.
ROnly install an approved trailer coupling on
your vehicle.
Further information on availability and on
installation is available from any authorized
Mercedes-Benz Center.
RThe bumpers of your vehicle are not suitable
for installing detachable trailer couplings.
RDo not install hired trailer couplings or other
detachable trailer couplings on the bumpers
of your vehicle.
RIf you do not need the ball coupling, remove
the ball coupling from the ball coupling
recess. This reduces the risk of damage to the
ball coupling.
iCheck the tire pressures when towing a
trailer. You will find the values in the tire pres-
sure table in the fuel filler flap of the vehicle
(
Ypage 266).
You will find installation dimensions and loads
under "Technical data" (
Ypage 297).
Towing a trailer167
Driving an d parking
Z

The maximum noseweight of the trailer drawbar
on the ball coupling for up to 3 people is 562 lbs
(255 kg). The maximum permissible trailer draw-bar noseweight for more than 3 persons and the
maximum load in the trunk can be found in the
trailer drawbar noseweight table (
Ypage 298).
However, the actual noseweight must not
exceed the value given on the trailer tow hitch or trailer identification plates. The lowest weight
applies.
Please note that when towing a trailer,
PARKTRONIC (
Ypage 158) and Blind Spot
Assist (Ypage 154) are only available with lim-
itations, or not at all.
iOn 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
XOn long and steep downhill gradients, select
shift range 1,2or 3(Ypage 123) in good
time.
iThis also applies if you have activated cruise
control or SPEEDTRONIC.
XIf necessary, shift the transfer case to LOW
RANGE (Ypage 162).
This will use the braking effect of the engine,
so that less braking will be required to main-
tain the speed. This relieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly. If you
need additional braking, depress the brake
pedal repeatedly rather than continuously.
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 pre-
scribed maximum speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum 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 max- imum rear axle load when towing a trailer, the
vehicle/trailer combination may not exceed a
maximum speed of 60 mph (100 km/h) for rea-
sons concerning the operating permit. This also applies in countries in which the permissible
maximum speed for vehicle/trailer combina-
tions is above 60 mph (100 km/h). When towing a trailer, your vehicle's handling
characteristics will be different in comparison to
when driving without a trailer and it will con-
sume more fuel.
On long and steep downhill gradients, you must
select shift range
1,2or 3in good time.
iThis also applies if you have activated cruise
control or DISTRONIC PLUS.
This will use the braking effect of the engine, so
that less braking will be required to maintain the
speed. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly. If you need additional
braking, depre ss the bra
ke pedal repeatedly
rather than continuously.
Driving tips
If the trailer swings from side to side:
XDo not accelerate.
XDo not counter-steer.
XBrake if necessary.
RMaintain a greater distance from the vehicle
in front than when driving without a trailer.
RAvoid braking abruptly. If possible, brake gen- tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
RThe values given for gradient-climbing capa-
bilities from a standstill refer to sea level.
When driving in mountainous areas, note that
the power output of the engine and, conse-
quently, the vehicle's gradient-climbing capa-
bility, decreases with increasing altitude.
Trailer power supply
!
You can connect accessories with a maxi-
mum power consumption of 180 W to the
permanent power supply.
You must not charge a trailer battery using the
power supply.
The trailer socket of your vehicle is equipped at
the factory with a permanent power supply.
The permanent power supply is supplied via
trailer socket pin 9.
A qualified specialist workshop can provide
more information about installing the trailer
electrics.
