Before attaching a trailer, lubricate  
the coupling ball. However, do not do  
so if a stabiliser, which acts on the  
coupling ball, is being used to reduce

maximum values which must not be  
exceeded. The actual trailer load is  
the difference between the actual  
gross weight of the trailer and the  
actual coupling socket load with the  
trailer coupled.  
The permissible trailer loads are  
specified in the vehicle documents. In  
general, they are valid for inclines up  
to 12%.  
The permissible trailer load applies  
up to the specified incline and at sea  
level. Since engine power decreases  
as altitude increases due to the air  
becoming thinner, therefore reducing  
climbing ability, the permissible gross  
train weight also decreases by 10%  
for every 1000 m of altitude. The  
gross train weight does not have to be  
Entrust retrofitting of towing  
equipment to a workshop. It may be  
necessary to make changes that  
affect the cooling system, heat  
shields or other equipment.  
During trailer towing do not exceed a  
speed of 50 mph. A maximum speed  
of 60 mph is only appropriate if an  
oscillation damper is used and the  
permissible gross trailer weight does  
not exceed the vehicle's curb weight.  
For trailers with low driving stability  
and caravan trailers, the use of an  
oscillation damper is strongly  
recommended.  
If the trailer starts snaking, drive more  
slowly, do not attempt to correct the  
steering and brake sharply if  
necessary.  
When driving downhill, drive in the  
same gear as if driving uphill and  
drive at a similar speed.  
The bulb outage detection function for  
trailer brake light cannot detect a  
partial bulb outage. E.g. in case of  
four bulbs with a power of 5 W each,  
the function only detects light outage  
when only a single 5 W light remains  
or none remain.  
Trailers equipped with LED lights are  
not suitable for the wiring harness of  
this trailer hitch.

reduced when driving on roads with  
slight inclines (less than 8%, e.g.  
motorways).  
The permissible gross train weight  
must not be exceeded. This weight is  
specified on the identification plate  
3 256.  
Rear axle load  
Fitting the coupling ball bar  
When the trailer is coupled and the  
towing vehicle fully loaded, the  
permissible rear axle load (see  
identification plate or vehicle  
documents) may be exceeded by  
60 kg, the gross vehicle weight rating  
must not be exceeded. If the  
permissible rear axle load is  
exceeded, a maximum speed of  
60 mph applies.  
Vertical coupling load  
The vertical coupling load is the load  
exerted by the trailer on the coupling  
ball. It can be varied by changing the  
weight distribution when loading the  
trailer.  
The maximum permissible vertical  
coupling load (70 kg) is specified on  
the towing equipment identification  
plate and in the vehicle documents.  
Towing equipment  
Disengage and fold down the socket.  
Remove the sealing plug from the  
opening for the coupling ball bar and  
stow it.  
Caution  
When operating without a trailer,  
remove the coupling ball bar.  
Always aim for the maximum vertical  
coupling load, especially in the case  
of heavy trailers. The vertical coupling  
load should never fall below 25 kg.

Checking the tensioning of the  
coupling ball bar  
Remove the cover from the lock  
of the rotary knob and verify  
whether the rotary knob is  
locked. If the rotary knob cannot  
be turned, it is locked.  
Pull out rotary knob and turn  
clockwise as far as it will go.  
Red marking on rotary knob must  
point towards green marking on  
coupling ball bar.  
The gap between the rotary knob  
and the coupling ball bar must be  
approx. 6 mm.  
Inserting the coupling ball bar  
Otherwise, the coupling ball bar must  
be tensioned before being inserted:  
Unlock coupling ball bar by  
turning key to position c.

marking on coupling ball bar.  
9 Warning  
There must be no gap between  
the rotary handle and the  
coupling ball bar.  
Do not touch rotary handle during

The coupling ball bar must be  
locked and the key removed.  
Open the protective flap and turn the  
key to position c to unlock the  
coupling ball bar.  
Pull out rotary handle and turn  
clockwise as far as it will go. Pull out  
coupling ball bar downwards.

9 Warning  
Towing a trailer is permitted only  
when a coupling ball bar is fitted  
correctly. If the coupling ball bar  
does not engage correctly, seek  
the assistance of a workshop.  
Insert sealing plug in opening. Fold  
away socket.
