unhitched from the vehicle. The vehicle could move up and down if the load changes or if there is
damage to the tyres, for example. If this happens, a great deal of force will be exerted on the towing
bracket and trailer, which could lead to damage to the vehicle and trailer.

If there is a fault in the vehicle or trailer electrical systems or in the anti-theft alarm, have the vehicle
checked by a qualified workshop.

If the 12-volt vehicle battery charge level is low, the electrical connection to the trailer will be
interrupted automatically.
Loading the trailer
First read and observe the introductoryinformation and safety warnings
Trailer weight and drawbar load
The trailer weight is the weight that the vehicle can pull
The drawbar load is the load that is exerted vertically from above onto the ball head of the towing
bracket.
The figures for trailer weights and drawbar weights that are given on the data plate of the towing
bracket are for certification purposes only. The correct values for your specific model, which may be
lower than these figures, are given in the vehicle registration documents. All data in the official
vehicle documents take precedence over these data.
The maximum permitted drawbar load exerted by the trailer drawbar on the ball head of the towing
bracket must not exceed 80 kg.
In the interest of driving safety, Volkswagen recommends that you always use the maximum
drawbar load. The handling of the vehicle combination will be impaired if the drawbar load is too
low.
The drawbar load increases the weight on the rear axle and reduces the maximum payload of the
vehicle as a result.
Gross combination weight
The gross combination weight is made up of the actual weight of the loaded vehicle and of the
loaded trailer.
In some countries, trailers are divided into different classes. Volkswagen recommends that you
contact a qualified workshop to find out about suitable trailers.
Loading the trailer
The weight of the load should be distributed evenly. The maximum permitted drawbar load should
be utilised. Do not place the load only at the front or the rear of the trailer:

The discharged 12-volt vehicle battery must be properly connected to the vehicle's electrical system.
The vehicles must not touch. Otherwise electricity could flow as soon as the positive terminals are
connected.
Ensure that the battery clamps have good metal-to-metal contact with the battery terminals.
If the engine does not start immediately, switch off the starter after about 10 seconds and try again
after about a minute.
If the engine still does not start, seek expert assistance.
Attaching the jump leads
The jump leads should be connected only in the order A B C DFig. 177
The black jump lead should never be connected to the negative terminal (-volt vehicle
battery. Connecting the lead to the negative terminal can cause incorrect condition evaluation of the
