Trailer towing -> Ball mount for Your Volkswagen Passat SUV Seventh Generation (2010-2014)

WARNING  
Improper trailer towing can cause loss of vehicle control and  
serious personal injury.  
Driving with a trailer and carrying heavy or bulky items  
changes the way the vehicle handles and increases the dis-  
tance it needs to stop safely.  
Always watch what is happening up ahead and around you.  
Brake earlier than you would if you were not towing a trailer.  
Always adapt your speed and driving to the heavier load and  
the weight distribution in the vehicle. Take road, weather, traf-  
fic, and visibility conditions into account as well.  
Reduce your speed even more than you otherwise would  
when going downhill and under unfavorable load, weather, or  
wind conditions.  
Drive especially carefully and accelerate gently. Always avoid  
sudden maneuvers and hard braking.  
Be especially careful when passing other vehicles.  
Reduce speed immediately if the trailer shows even the  
slightest sign of swaying.  
Never try to stop the swaying by accelerating.  
Always obey speed limits. In some areas speed limits for ve-  
hicles towing trailers are lower than for vehicles without trail-  
ers.

¤ Please first read and note the introductory information and  
heed the WARNINGS  
Your vehicle is not equipped with a trailer hitch or preparations for the  
installation of a trailer hitch. If you must tow a trailer, you must have  
the necessary electrical wiring and socket together with a suitable  
trailer hitch installed. Because towing a trailer places a great deal of  
stress on the vehicle, the attachment of a trailer to the vehicle and the  
dimensions of the receiver and ball mount are very important so that  
the extra forces the vehicle has to withstand can be properly handled.  
The receiver used requires both a ball mount and a ball that meet  
special requirements regarding geometry and size. This applies to  
both the height of the ball above the surface where it attaches  
fig. 108 (A), and the pin-to-ball distance (B).  
These dimensions are important because they help determine the  
way that the forces that arise during towing are applied to the receiver  
and its attachments to the vehicle. If you buy a ball mount and ball,  
make sure that they meet the following specifications.  
Ball mount dimensions  
The drop height (A) from the center of the ball to the center of the  
hole for the securing pin on the ball mount must be at least 1 inch  
(25.4 mm) and at most 27 /8 inches (73 mm).  
The pin-to-ball distance (B) from the center of the ball to the center  
of the hole for the securing pin on the ball mount must be no more  
than 7 inches (178 mm).  
The ball diameter must be no more than 11/4 inches (32 mm).  
A ball mount and ball combination that does not meet these specifica-  
tions can damage your vehicle and may even fail in use ꢀ  
.
Never install a “weight distributing” or “load equalizing” trailer hitch on  
your vehicle. The vehicle is not designed for this kind of trailer hitch ꢀ  
.
WARNING  
An improperly installed or unsuitable trailer hitch can cause the  
trailer to separate from the towing vehicle and result in a major  
accident with serious personal injuries.  
Have any trailer hitch retrofit or other work on a trailer hitch  
done by a qualified workshop.  
CAUTION  
The ball mount sticks out behind the rear bumper and can  
cause injury to pedestrians and cyclists.  
To reduce the risk of injury in rear-end collisions, and the risk  
to pedestrians and cyclists when the vehicle is parked, always  
remove the ball carrier when you are not towing a trailer.  
NOTICE  
Never use a ball larger than 11/4 inches (32 mm) on your vehi-  
cle. The vehicle was not designed to tow heavier trailers with a  
receiver larger than the specified ball. The increased loads can  
damage the attachment points for the trailer hitch.  
Never use an adapter to increase the size of the trailer hitch  
receiver from 11/4 inches (32 mm) to 2 inches (50.8 mm) or more  
to tow a trailer that is heavier than the maximum permissible  
trailer weight that your vehicle can tow.  
You can use an adapter if required for the proper installation  
of a bicycle rack or other similar carrier as long as the maximum  
weight limits are observed. When using bicycle racks or similar  
carriers, make sure that the rear lights are not blocked.  
Only use trailer hitches that are approved by the hitch manu-  
facturer for your vehicle and model.
