Trailer towing -> Hitching up and connecting a trailer for Your Volkswagen Passat SUV Seventh Generation (2010-2014)

If the trailer uses too much electricity, the vehicle's electronics  
may be damaged.  
Never connect the electrical system for the trailer directly to  
the electrical connections for the rear lights or to any other un-  
suitable power sources. Use only a suitable connector to pro-  
vide power to the trailer.  
If you tow a trailer frequently, Volkswagen recommends having  
the vehicle serviced between the regular maintenance and inspection  
intervals because of the extra load it has to pull.

Safety chains  
Always make sure that the safety chains are properly attached to the  
towing vehicle. Leave enough slack in the chains so that you can go  
around corners without stretching the chains. The safety chains must  
not drag on the ground, however.

Make sure that the trailer lights work properly and meet legal re-  
quirements. Do not exceed the maximum power consumption for the  
trailer Maximum power consumption for the trailer.  
WARNING  
Improper connections to the vehicle electrical system can  
cause malfunctions that affect the entire vehicle electrical sys-  
tem, which can lead to accidents and serious personal injury.  
Have any work on the electrical system done by an author-  
ized Volkswagen dealer or authorized Volkswagen Service Fa-  
cility.  
Never connect the electrical system for the trailer directly to  
the electrical connections for the rear lights or to any other un-  
suitable power sources. Use only a suitable connector to pro-  
vide power to the trailer.  
NOTICE  
Never attach a trailer to the vehicle or leave it attached to the  
vehicle when the trailer is supported by a trailer jack or blocks.  
Various things (such as a change in trailer or vehicle load or a  
flat tire) can lower or raise the vehicle. This subjects the trailer  
hitch and the trailer to strong forces that can damage the vehicle  
or the trailer.  
If the engine is switched off and accessories in the trailer are on  
and use electricity from the vehicle, the vehicle battery will be drained  
as long as the electrical systems of the vehicle and the trailer are  
connected.

Maximum permissible trailer weight and tongue weight  
Maximum permissible trailer weight is the load that the vehicle can  
tow . The tongue load or tongue weight is the load pressing down  
on the trailer hitch ball mount.  
The maximum permissible trailer weight and tongue weight for your  
vehicle are listed on Maximum permissible trailer weight in this  
Manual.  
The trailer load and tongue weight on the type identification plate for  
the trailer hitch are only test values. The vehicle-specific figures are  
often lower than these values. In some countries, but generally not in  
the United States, the vehicle-specific figures are listed in the official  
vehicle documents. Specifications in official vehicle documents al-  
ways take precedence.  
To help ensure optimum handling and driving safety, Volkswagen  
recommends always using the maximum permissible tongue weight.  
If the tongue weight is too low, the vehicle and trailer will not handle  
as well.  
Tongue weight increases the load on the rear axle and, in turn, re-  
duces the remaining load your vehicle can carry Determining the  
correct load limit.
