Trailer towing -> Technical requirements for Your Volkswagen Jetta 4 Door Sixth Generation (2011-2018)

Technical requirements  
Please first read and note the introductory information and heed the WARNINGS  
Use only a weight-carrying trailer hitch designed and approved for the gross weight of the trailer you  
want to tow. The trailer hitch must be suitable for your vehicle and trailer and must be securely bolted  
to the appropriate place on the vehicle chassis. Use only a trailer hitch with a removable ball mount.  
Always check with the trailer hitch manufacturer to make sure that you are using the correct trailer  
hitch and carefully follow the hitch manufacturer's instructions. Never install a “weight-distributing” or  
“load-equalizing” trailer hitch on your vehicle. The vehicle is not designed for this kind of trailer hitch

.
Do not use a bumper-mounted trailer hitch  
Never install a trailer hitch on the bumper or on the bumper attachments. The trailer hitch must not  
interfere with the impact-absorbing bumper system. Do not make any changes to the vehicle exhaust  
and brake systems. From time to time, check that all trailer hitch mounting bolts are securely fastened.  
When you are not towing, remove the trailer hitch. This helps keep the trailer hitch from causing  
damage if your vehicle is hit from behind.  
Engine cooling system  
Towing a trailer makes the engine and its cooling system work harder. It is important that the engine  
cooling system is up to the job. Make sure that the cooling system has enough coolant.  
Trailer brakes  
If your trailer has its own brakes, make sure it meets all regulations. The trailer brake system must  
never be directly connected to the vehicle's brake system.  
Safety chains  
Always use safety chains between your vehicle and the trailer, Hitching up and connecting a trailer.  
Trailer taillights  
Trailer lights must meet all regulations, Hitching up and connecting a trailer.  
Never connect the trailer lights directly to the electrical system of your vehicle.  
Outside mirrors  
If you cannot see the traffic behind you using the regular outside mirrors, then you must install  
extended mirrors. Extended mirrors may also be required by law in some countries/states/provinces.  
Always adjust the outside mirrors before driving. It's vital that you always have a clear view to the rear  
of the vehicle.

WARNING  
An improperly installed or incorrect trailer hitch can cause a trailer to separate from the  
tow vehicle and cause serious personal injuries.  
If you don't have to tow a trailer any more, remove the entire trailer hitch. Always seal all  
bolt holes to prevent water and deadly exhaust fumes from getting into the vehicle.  
NOTICE  
If the trailer lights are not connected properly, the vehicle's electronics may be damaged.  
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 unsuitable power sources. Use only a suitable connector to  
provide 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.  
Hitching up and connecting a trailer  
Please first read and note the introductory information and heed the WARNINGS  
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.  
Trailer taillights  
Make sure that the trailer lights work properly and meet legal requirements. Do not exceed the  
maximum power consumption for the trailer, Technical requirements.  
WARNING  
Improper connections to the vehicle electrical system can cause malfunctions that affect the  
entire vehicle electrical system, which can lead to accidents and serious personal injury.  
Have any work on the electrical system done by an authorized Volkswagen dealer or  
authorized Volkswagen Service Facility.  
Never connect the electrical system for the trailer directly to the electrical connections for  
the rear lights or to any other unsuitable power sources. Use only a suitable connector to  
provide 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.
