Towing a trailer
Important safety notes
GWARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi- cle/trailer combination could even rollover.
There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
GWARNING
If you install a ball coupling other than the one
delivered with the vehicle, the trailer tow hitch
and the rear axle may be overloaded. This
applies especially if the ball coupling in ques-
tion is longer or angled differently. This could
seriously impair the driving characteristics
and the trailer can come loose. There is a risk
of an accident.
Only install the ball coupling delivered with
the vehicle or a ball coupling that is designed to meet your trailer towing requirements. Do
not modify the ball coupling or the trailer tow
hitch.
GWARNING
If the ball coupling is not installed correctly or not secured with the bolt provided and the
corresponding spring cotter, the trailer may
come loose. There is a risk of an accident.
Always install and secure the ball coupling as
described. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter.
!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
frame.
The installation of a trailer tow hitch is only per-
missible if a towing weight is specified in your
vehicle documents. If this is not the case, then
the vehicle is not approved for the towing of a
trailer.
For more information, please contact a qualified
specialist workshop.
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 of the trailer drawbar on the ball coupling may cause damage.
Damage may be caused to the following:
RTowing vehicle
RTrailer
RBall 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.

This also applies if you have activated cruise
control or the speed limiter.
XIf necessary, shift the transfer case toLOW
RANGE (Ypage 149).
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
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 (
Ypage 291). In the event of increased
rear axle load, the car/trailer combination may
not exceed a maximum speed of 60 mph
(100 km/h) for reasons concerning the operat-
ing permit. This also applies in countries in
which the maximum permissible speed for car/ trailer combinations is greater than 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.
Driving tips
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.
If the trailer swings from side to side:
XDo not accelerate.
XDo not counter-steer.
XBrake if necessary.
Assembling the ball coupling
GWARNING
The ball coupling can be damaged if the nut on
the ball coupling is tightened using the incor-
rect torque. As a result, the trailer may
detach. There is a risk of an accident.
Immediately after installing, have the tighten-
ing torque checked at a qualified specialist
workshop.
!Mercedes-Benz recommends that you only
use ball couplings tested and approved for
use on Mercedes-Benz vehicles. This helps to avoid damage to the vehicle.
Observe the manufacturer's installation
instructions if you use a ball coupling other
than the one supplied.
XSlide ball coupling :through the hole in ball
coupling carrier bar ;to the stop.
XSlide lock washer ?onto the thread of ball
coupling =to the stop.
XScrew on nut Aas far as it will go.

XUsing a torque wrench, tighten nutBwith a
torque of 516 lb-ft (700 Nm) .
XCheck that the length of overhanging thread
Cbeneath nut Bis at least 0.32 in (8 mm) .
XCheck that the assembled ball coupling has
been assembled correctly.
Also observe the height of the trailer coupling
and the trailer manufacturer's instructions.
Depending on the height of the trailer coupling,
it may be necessary to rotate the ball coupling
by 180° when assembling on the ball coupling
carrier bar. The assembly process is identical.
Installing the ball coupling
GWARNING
If the ball coupling is not installed correctly or not secured with the bolt provided and the
corresponding spring cotter, the trailer may
come loose. There is a risk of an accident.
Always install and secure the ball coupling as
described. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter.
GWARNING
If the ball coupling is not correctly installed
and secured, it can come loose during the
journey and endanger other road users. There is a risk of an accident and injury.
Always install and secure the ball coupling as
described. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter.
XPull protective cap =in the direction of the
arrow, out of the ball coupling recess.
XInsert the ball coupling horizontally into ball
coupling recess ?in the direction of the
arrow.
XMake sure that the hole in ball coupling Ais
in line with the hole in ball coupling recess B.

Towing a trailer
There are several legal requirements for towing
a trailer, e.g. the maximum permissible speed.
Make sure that your car/trailer combination
complies with the local regulations:
Rin your place of residence
Rat your destination
The police and local authorities can provide reli- able information.
In order to accumulate driving experience and
accustom yourself to the new handling charac-
teristics, practice the following at a location
where there is no traffic:
RCornering
RStopping
RBacking up
Before driving, check the following:
RTrailer tow hitch
RSafety switch for braked trailers
RSafety chains
RElectrical connections
RLighting system
RWheels and tires
RLoad-securing measures
Adjust the exterior mirrors to provide an unob-
structed view of the rear section of the trailer.
Trailers with electronically controlled
brakes: pull away carefully in the vehicle/trailer
combination, brake manually using the brake
controller and check whether the brakes func-
tion correctly.
Check the load securing measures on a regular
basis.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
with when driving without a tra
iler.
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
Avoid sudden steering movements.
Avoid braking abruptly. If possible, brake gently
at first to allow the trailer to run on. Then,
increase the braking force rapidly. When overtaking, pay particular attention to the
extended length of your vehicle/trailer combi-
nation.
Due to the length of the vehicle/trailer combi-
nation, you require additional road space when
overtaking before you can change back to the
original lane.
If the automatic transmission repeatedly shifts
between gears on uphill or downhill gradients,
shift to a lower gear.
Driving in a lower gear and at a reduced speed
decreases the risk of engine damage.
Avoid constant braking. Otherwise, the vehicle
brakes and possibly also the trailer brakes may
overheat.
When driving downhill, shift to a lower gear to
utilize the engine's braking effect.
If the coolant temperature increases dramati-
cally while the air-conditioni ng s
ystem is
switched on, switch off the air-conditioning sys- tem.
Coolant heat can also be dissipated by opening
the windows and switching the ventilation
blower and the interior temperature to the high-
est level.
Decoupling a trailer
GWARNING
If you uncouple a trailer with the overrun
brake engaged, you could trap your hand
between the vehicle and the trailer drawbar.
There is a risk of injury.
Do not uncouple a trailer if the overrun brake
is engaged.
!Do not disconnect a trailer with an engaged
overrun brake. Otherwise, your vehicle could
be damaged by the rebounding of the overrun
brake.
XApply the parking brake.
XMake sure that the automatic transmission is
set to position P.
XSecure the vehicle and trailer against rolling
away.
XClose all doors, including the rear door.
XRemove the trailer cable.
XRemove the safety chains, if there are any.
XUncouple the trailer.
