Trailer hitch  
General information  
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  
snaking movements.  
Only use towing equipment that has  
been approved for your vehicle.  
Entrust retrofitting of towing  
particular vehicle. Additional  
equipment may result in slightly  
higher results than the stated  
consumption and CO2 figures.  
Furthermore, fuel consumption is  
dependent on personal driving style  
as well as road and traffic conditions.  
equipment to a workshop. It may be  
necessary to make changes that  
affect the cooling system, heat  
shields or other equipment.  
For trailers with low driving stability  
and caravan trailers with a permitted  
gross vehicle weight of more than  
1000 kg a speed of 50 mph must not  
be exceeded; the use of a stabiliser is  
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.  
Adjust tyre pressure to the value  
specified for full load 3 250.  
The bulb outage detection function for  
trailer brake light cannot detect a  
partial bulb outage, e.g. in case of four  
times five watt bulbs, the function only  
detects lamp outage when only a  
single five Watt lamp remains or none  
remain.  
Fitting of towing equipment could  
cover the opening of the towing eye.  
If this is the case use the coupling ball  
bar for towing. Always keep the  
coupling ball bar in the vehicle when  
not in use.

The permissible gross train weight  
must not be exceeded. This weight is  
specified on the identification plate  
3 238.  
Rear axle load  
Petrol and diesel engines  
When the trailer is coupled and the  
towing vehicle fully loaded, the  
permissible rear axle load (see  
identification plate or vehicle  
documents) for passenger vehicles  
may be exceeded by 70 kg for the 5-  
door vehicle and 60 kg for the 3-door  
vehicle, the gross vehicle weight  
rating by 55 kg.  
Trailer towing  
Trailer loads  
The permissible trailer loads are  
vehicle and engine-dependent  
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 gradients  
up to max. 12%  
The permitted trailer loads apply up to  
the specified incline and up to an  
altitude of 1000 metres above 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 metres of additional  
altitude. The gross train weight does  
not have to be reduced when driving  
on roads with slight inclines (less than  
8%, e.g. motorways).  
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.  
Petrol and diesel engines  
Engine B14XEL LPG  
The maximum permissible vertical  
coupling load (55 kg) is specified on  
the towing equipment identification  
plate and in the vehicle documents.  
Always aim for the maximum load,  
especially in the case of heavy  
trailers. The vertical coupling load  
should never fall below 25 kg.  
When the trailer is coupled and the  
towing vehicle fully loaded, the  
permissible rear axle load (see  
identification plate or vehicle  
documents) for passenger vehicles  
may be exceeded by 70 kg for the 5-  
door vehicle and 70 kg for the 3-door  
vehicle and the gross vehicle weight  
rating by 45 kg.  
Engine B14XEL LPG  
The maximum permissible vertical  
coupling load (45 kg) is specified on  
the towing equipment identification  
plate and in the vehicle documents.  
Always aim for the maximum load,  
especially in the case of heavy  
trailers. The vertical coupling load  
should never fall below 25 kg.  
Delivery van  
When the trailer is coupled and the  
towing vehicle fully loaded, the  
permissible rear axle load (see  
identification plate or vehicle  
documents) for passenger vehicles  
may be exceeded by 60 kg and the  
gross vehicle weight rating by 55 kg.

Driving and operating  
General  
Disengage and fold down the socket.  
Remove the sealing plug from the  
opening for the coupling ball bar and  
stow it.  
If the permitted rear axle load is  
exceeded a maximum speed of  
60 mph applies. If lower national  
maximum speeds are specified for  
trailer operation, they must be  
complied with.  
Checking the tensioning of the  
coupling ball bar  
Towing equipment  
Caution  
When inserting, fit protective cap over  
rotary knob with key.  
When operating without a trailer,  
remove the coupling ball bar.  
Fitting the coupling ball bar  
Stowage of coupling ball bar  
The coupling ball bar is stowed in a  
bag in the spare wheel well and  
secured to the lashing eyes in the  
load compartment.  
The rotary knob rests on the  
coupling ball bar.  
Green marking on the rotary  
knob is not visible.  
Locking pin at the top of the  
coupling ball bar is set inwards.  
The key is in the lock.

Otherwise, the coupling ball bar must  
be tensioned before it is inserted into  
the coupling housing:  
Inserting the coupling ball bar  
Green marking on the rotary knob is  
visible.  
Lock coupling ball bar and remove  
key.  
Insert the tensioned coupling ball bar  
in the opening and push firmly  
upwards until it audibly engages.  
Place the key in the lock and  
unlock the coupling ball bar.  
Push the rotary knob onto the  
coupling ball bar and rotate right  
while pressed down until it  
engages. The key remains in the  
lock.  
The rotary knob snaps back into its  
original position resting against the  
coupling ball bar without a gap.  
9 Warning  
Do not touch rotary knob during  
insertion.

Driving and operating  
Eye for break-away stopping cable  
Insert sealing plug in opening for  
coupling ball bar. Fold away socket.  
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.  
Trailer stability assist  
If the system detects snaking  
movements, engine power is reduced  
and the vehicle/trailer combination is  
selectively braked until the snaking  
ceases. While system is working keep  
steering wheel as still as possible.  
Dismounting the coupling ball bar  
Trailer stability assist is a function of  
the Electronic Stability Control 3 151.  
Attach breakaway stopping cable to  
eye.  
Check that the coupling ball bar is  
correctly installed  
Green marking on rotary knob is  
visible.  
There must be no gap between  
the rotary knob and the coupling  
ball bar.  
Insert the key in the lock and unlock  
the coupling ball bar.  
Push the rotary knob onto the  
coupling ball bar and rotate right while  
pressed down until it engages. Pull  
out the ball bar downwards.  
The coupling ball bar must be  
firmly engaged in the opening.  
The coupling ball bar must be  
locked and the key removed.
