R you cut the corner on a bend Towing a trailer
If you couple up a trailer, make sure that you
have correctly established the electrical con-
nection. This can be accomplished by checking
the trailer lighting. Towing a trailer
Important safety notes
G
WARNING
You could lose control of the vehicle/trailer
combination if it begins to swerve. The vehi-
cle/trailer combination could even overturn.
There is a risk of an accident.
On no account should you attempt to
straighten out the vehicle/trailer combina-
tion by increasing speed. Decrease your
speed and do not countersteer. Brake if nec-
essary. G
WARNING
If the maximum permissible load for a carrier system is exceeded, the carrier could come
loose from the vehicle and endanger other
road users. There is a risk of an accident and injury.
Never exceed the maximum permissible load
when using a carrier.
! If you have a trailer tow hitch retrofitted,
changes to the engine cooling system may be necessary, depending on the vehicle type.
If you have a trailer tow hitch retrofitted,
observe the anchorage points on the chassis.
Retrofitting a trailer tow hitch is only permissible
if a trailer load is specified in your vehicle docu-
ments. If this is not the case, then the vehicle is not approved for towing a trailer.
For more information, please contact a qualifiedspecialist workshop.
Exceeding the maximum permissible nose-
weight of the trailer drawbar on the ball coupling
may cause damage.
Damage may be caused to the following:
R towing vehicle
R trailer 218

R
ball coupling
R trailer tow hitch
The vehicle/trailer combination could become
unstable.
The vehicle/trailer combination could also
become unstable if the noseweight used is lower
than the minimum permissible noseweight.
To avoid hazardous situations:
R make sure to check the noseweight before
each journey
R use a noseweight as close as possible to the
maximum noseweight
R do not exceed the maximum permissible
noseweight
R do not use a noseweight lower than the min-
imum noseweight
Make sure that the following values are not
exceeded:
R the permissible noseweight
R the permissible trailer load
R the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
The applicable permissible values, which must
not be exceeded, can be found:
R in your vehicle documents
R on the type plates for the trailer
R on the vehicle identification plate
If the values differ, the lowest value applies.
You will find permissible trailer loads under
"Technical data" (Y page 380).
When reversing the towing vehicle, make sure
there is nobody between the trailer and the vehi- cle.
Couple and uncouple the trailer carefully. If you
do not couple the trailer to the towing vehicle
correctly, the trailer could become detached.
When towing a trailer, your vehicle's handling
characteristics will be different to when driving
without a trailer.
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 circle
This can impair the vehicle's handling charac-
teristics. 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 exceed the maximum permissible speed for
your vehicle/trailer combination. Notes on towing a trailer
General notes When towing a trailer, set the tyre pressure on
the rear axle of the towing vehicle for a maxi-
mum load. Further information on the tyre pres-
sure table in the fuel filler flap (Y page 359).
You will find permissible trailer loads under
"Technical data" (Y page 380).
Driving tips Observe the information on ESP
®
trailer stabili-
sation (Y page 76).
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
permitted speed is. Observe the maximum per-
missible speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum permissible rear axle load is increased
when towing a trailer. See the "Technical data"
section to find out whether this applies to your
vehicle (Y page 381). In the event of increased
rear axle load, the car/trailer combination may
not exceed a maximum speed of 100 km/ hfor
reasons concerning the operating permit. This
also applies in countries in which the maximum
permissible speed for car/trailer combinations
is greater than 100 km/h.
When towing a trailer, your vehicle's handling
characteristics will be different to when driving
without a trailer and the vehicle will consume
more fuel.
Shift to a lower gear in good time on long and
steep downhill gradients.
This also applies in the case of:
R activated DISTRONIC PLUS
R activated cruise control Towing a trailer
219Driving and parking Z

This will use the braking effect of the engine, so
less braking will be required to maintain the
vehicle 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.
Driving tips R
Maintain a greater distance to the vehicle in
front than when driving without a trailer.
R Avoid braking abruptly. If possible, brake gen-
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
R The 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 from a standstill, decrease with increas- ing altitude.
If the trailer swings from side to side:
X Do not accelerate under any circumstances.
X Do not countersteer.
X Brake, if necessary. Swivelling the ball coupling in/out
Important safety notes G
WARNING
If the ball coupling is not engaged, the trailer
may come loose. There is a risk of an accident.
Make sure that the ball coupling is securely
engaged and locked in position.
! Do not attempt to speed the up the swing-
out procedure by applying additional pressure
with your foot. The system could otherwise be
mechanically damaged.

WARNING
If you uncouple a trailer with an engaged over- run brake, you could trap your hand between
the vehicle and the trailer drawbar. This poses a risk of injury.
Do not uncouple a trailer with an engaged
overrun brake. G
WARNING
Vehicles with level control:
If you disconnect the trailer cable, the vehicle is lowered. This can cause you or others to
become trapped between the vehicle body
and tyres, or underneath the vehicle. This
poses a risk of injury.
Make sure that no-one is in the immediate
vicinity of the wheel arch or underneath the
vehicle when disconnecting the trailer cable. !
Do not disconnect a trailer with an engaged
overrun brake. Otherwise, your vehicle could
be damaged by the rebounding of the overrun
brake.
! Remove the adapter cable before folding in
the ball coupling. You could otherwise dam-
age the rear bumper and the adapter cable.
X Apply the electric parking brake manually.
X Shift the transmission to position P.
X Switch off the engine.
X Secure the vehicle and trailer against rolling
away.
X Remove the trailer cable and uncouple the
trailer. Trailer power supply
! Accessories with a maximum power con-
sumption of 180 W can be connected to the
permanent power supply.
The trailer battery may not be charged from
the power supply.
When it leaves the factory, your vehicle's trailer
socket is equipped with a permanent power
supply and a power supply that is switched on
via the ignition lock.
The permanent power supply is supplied via
trailer socket pin 9.
The power supply that is switched on via the
ignition lock is supplied via trailer socket pin 10.
The trailer's permanent power supply is
switched off in the event of low on-board voltage
and after six hours at the latest.

or
X Press the Start/Stop button once on vehicles
with KEYLESS-GO or the KEYLESS-GO start
function (Y page 144). Failure check for LEDs
If LED lamps are fitted in the trailer, a malfunc-
tion message may appear in the multifunction
display even if there is no fault. The reason for
the error message may be that the current has
fallen below the minimum of 50 mA.
To ensure reliable operation of the failure indi-
cator, each LED chain in the trailer lighting must
be guaranteed a minimum current of 50 mA. Trailer with 7-pin connector
General notes Trailer with 7-pin connector:

General notes
Trailer tow hitch (example with additional
guide pin)
Depending on the bicycle rack's design, you can transport up to four bicycles on it:
R When attached by clamping onto the ball cou-
pling :, the maximum payload is 75 kg. You
can transport up to three bicycles.
R When attached to the ball coupling :and
also the guide pin ;, the maximum payload is
100 kg. You can transport up to four bicycles.
The payload is calculated from the weight of the
bicycle rack and the load of the bicycle rack. To transport bicycles with a total weight
between 75 kg and 100 kg, use only bicycle
racks with additional support on the guide
pin
;. Important safety notes
G
WARNING
The bicycle rack can detach from the vehicle if
you
R exceed the permissible payload of the
trailer tow hitch
R use the bicycle rack incorrectly
R attach the bicycle rack to the ball coupling
beneath the ball head
There is a risk of an accident.
For your safety and that of other road users,
observe the following:
R Always observe the permissible payload of
the trailer tow hitch.
R Use the bicycle rack only to transport bicy-
cles. Bicycle rack

R
Always attach the bicycle rack correctly by
clamping onto the ball head and, if possible,
to the guide pin on the ball coupling as well.
R To transport four bicycles, always use bicy-
cle racks with additional support on the ball
coupling's guide pin.
R Use only bicycle racks approved by
Mercedes-Benz.
R Always comply with the bicycle rack's oper-
ating manual.
! Using unsuitable bicycle racks or using
them incorrectly can cause damage to and
fractures in the trailer tow hitch.
Use only bicycle racks approved by
Mercedes-Benz. Bicycle racks cause your vehicle's driving char-
acteristics to change. The vehicle
R is heavier
R is restricted in its acceleration and gradient-
climbing capability
R has an increased braking distance
This can impair the vehicle's handling charac-
teristics. Adapt your driving style accordingly.
Maintain a safe distance and drive carefully.
When using bicycle racks, set the tyre pressure on the rear axle of the vehicle for the maximum
load. Further information on tyre pressure can
be found on the tyre pressure table
(Y page 359). Loading instructions
The greater the distance between the load's centre of gravity and the ball head, the higher the load exerted on the trailer tow hitch.
Therefore, observe the following notes:
R Attach heavy bicycles as close as possible to the vehicle.
R Always distribute the load on the bicycle rack as symmetrically as possible to the vehicle longi-
tudinal axis.
Before loading the bicycle rack, Mercedes-Benz advises you to remove all add-on parts from the
bicycles, e.g. bicycle baskets, child seats or batteries. This will allow you to improve the aerody-
namic resistance and the bicycle rack's centre of gravity.
Always secure bicycles against slipping and check that they are firmly seated at regular intervals.
Do not use tarpaulins or other covers. This could impair the driving characteristics and rear visibility. The aerodynamic resistance would also rise, and so would the load exerted on the trailer tow hitchas a result. 226
