Headlight adjustment
Towing a trailer can raise the front end of the vehicle enough for the dipped beam to dazzle other
road users. Use the headlight range control to lower the light cone as required. Vehicles with
dynamic headlight range control are adjusted automatically.
Things to note when driving with a trailer
If the trailer has an overrun brake, apply the brakes gently at first and then firmly. This will
prevent the jerking that can be caused by the trailer wheels locking.

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.

Retrofitting a towing bracket

Fig. 157 Dimensions and mounting points for retrofitting a towing bracket.
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Volkswagen recommends having the towing bracket retrofitted by a qualified workshop. The cooling
system may need to be modified or heat shields may need to be fitted. Volkswagen recommends
using a Volkswagen dealership for this purpose.
Dimensions
The dimensions ⇒ Fig. 157  must be observed in all cases when retrofitting a towing bracket. Always
observe the minimum distance given from the middle of the ball head Ⓓ to the surface of the road.
This also applies when the vehicle is fully laden, including maximum drawbar load.

Petrol
First read and observe the introductoryinformation and safety warnings⇒Introduction 
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 ⇒ .
Information on the fuel standards can be found in the chapter on fuel standards ⇒ Fuel standards .

NOTICE
Errors during refuelling or unsuitable fuel additives may cause damage to the vehicle.

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⇒Introduction 
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.

Winter-grade diesel fuel and filter preheater system
Winter-grade diesel fuel, which can be used at temperatures below -20°C (-4°F), is available during
the cold months. In countries with different climates, diesel with a different temperature behaviour
is offered. Information is available from your Volkswagen dealership, qualified workshops and filling
stations in the respective country.
Diesel vehicles are equipped with a filter preheater system. When using winter-grade diesel fuel, the
fuel system is safe for operation at temperatures down to around -24°C (-11°F). In order to ensure
that the vehicle can also be started at low outside temperatures, Volkswagen recommends parking
the vehicle in a location that is protected from the whether, e.g. in a garage ⇒ Troubleshooting .
Misfuelling prevention device
The tank filler neck in diesel vehicles may be fitted with a misfuelling prevention device. This is
intended to help ensure that the vehicle is refuelled only using diesel filler nozzles.
If the nozzle cannot be inserted correctly into the tank filler neck, first check whether you are using a
diesel filler nozzle. When you have made sure that you are using the correct filler nozzle, move the
diesel filler nozzle to and fro slightly with light pressure. This can open the misfuelling prevention
device and make it possible to refuel the vehicle. If the misfuelling prevention device still remains
closed, go to a qualified workshop and have the system checked.
If it is necessary to refuel the vehicle using a fuel canister in the event of an emergency, the
misfuelling prevention device will not open. In order to nevertheless fill the tank with fuel, pour the
diesel into the tank extremely slowly in very small quantities.
