Trailer towing -> Ball mount for Your Volkswagen Passat SUV Sixth Generation (2005-2010)

Do not release the parking brake lever until the engine starts to move the vehicle forward. If your  
vehicle has an automatic transmission, you can also depress and hold the brake pedal for added  
braking and then let up on the brake pedal when you feel that the vehicle “wants” to move forward.  
Drive ahead slowly.  
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 distance 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, traffic, 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 vehicles towing trailers are lower  
than for vehicles without trailers.  
Ball mount  
Fig. 117 Dimensions of the ball mount support.  
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. 117 (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 17/8 inches (47.6 mm).  
A ball mount and ball combination that does not meet these specifications 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 17/8 inches (47.6 mm) on your vehicle. 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 17/8 inches  
(47.6 mm) to 2 inches (50.8 mm) or more than 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 manufacturer for your vehicle and  
model.
