Trailer socket
A 13-pin trailer socket produces the electrical connection between the towing vehicle and the trailer.
When the vehicle electrically detects a trailer, the consumers in the trailer are supplied with an
electrical voltage via the electrical connection (pins 9 and 10). Pin 9 is assigned as the permanent
positive, enabling operation of the trailer interior lighting, for example.
Electrical consumers such as a caravan refrigerator are supplied with power only when the engine is
running (pin 10).
To avoid overloading the electrical system, do not connect the earth wires (pins 3, 11 and 13) with
each other.
If the trailer has a 7-pin plug you will need to use a suitable adapter cable. The function of pin 10 is
then not available.

trailer load and the increased combined towing weight of the vehicle and trailer.
When driving with this combination, drive particularly carefully and slowly.
Pulling off on slopes when towing a trailer
Depending on the steepness of the uphill gradient and the total weight of the trailer and vehicle, a
vehicle towing a trailer could roll back a short distance when moving off on a hill.
When towing a trailer, pull off on slopes as follows:

Petrol
First read and observe the introductoryinformation and safety warnings
Fill vehicles with a petrol engine only with unleaded petrol or petrol with a maximum ethanol
content of 10 % (E10)
Fuel grades differ according to the octane number. The vehicle may be filled with petrol that has a
higher octane number than the engine requires. However, this does not provide any advantage in
terms of fuel consumption or engine output.
The fuel quality affects the running properties, performance and service life of the engine. Refuel
with fuel that already contains suitable service additives

drive at medium engine speeds and avoid high engine loading. Avoid high engine speeds and heavy
engine loads. Refuel with petrol with the correct octane number as soon as possible.
Diesel
First read and observe the introductoryinformation and safety warnings
Fill vehicles with a diesel engine only with diesel or diesel with a maximum RME fuel content of 7 %

If you use diesel with a high sulphur content, the service intervals are shorter. Information on
countries where the diesel has a high sulphur content is available from your Volkswagen dealership
or a qualified workshop.

Periodic regeneration
The soot in the particulate filter is burnt off at high temperatures on a periodic basis.
To assist the regeneration of the particulate filter, Volkswagen recommends that you avoid making
only short journeys.
Noises, slight smells and increased engine speeds may occur during regeneration. The radiator fan
may run on while the vehicle is moving or when the engine has been switched off.

During the periodic regeneration process, the yellow indicator lamp does not light up.
