 Audi A1   Driving tips   Towing a trailer  Driving the Audi A1 with a trailer or caravan
There are a number of points which need to be checked before towing a trailer or caravan.
Observe the maximum permitted trailer weights Link.
Trailer weights
Never exceed the maximum permitted trailer weights.
If you do not load the trailer up to the maximum permitted trailer weight, you can then climb correspondingly steeper gradients.
The maximum trailer weights listed are only applicable for altitudes up to 1000 m above sea level. With increasing altitude the engine power and therefore the car's climbing ability are impaired because of the reduced air density, so the maximum trailer weight has to be reduced accordingly. The weight of the car and trailer must be reduced by about 10% for every further 1000 m (or part thereof). This figure refers to the combined weight of the (loaded) Audi A1 and (loaded) trailer.
The figures for the draw bar weight that appear on the identification plate of the towing bracket are for certification purposes only. The correct figures for your specific model, which may be lower than these figures for the towing bracket, are given in the registration documents and in Link. Also refer to Link.
Distributing the load
Distribute loads in the trailer so that heavy objects are as near to the axle as possible. Loads carried in the trailer must be secured to prevent them slipping. A badly distributed load can also affect handling. This can activate the trailer stabilisation feature and cause the Audi A1 to reduce speed.
Where possible, operate the trailer with the maximum permitted draw bar weight on the ball joint of the towing bracket, but do not exceed the specified limit.
Tyre pressure
Check the tyre pressures on your car, and adjust for "full load" conditions (refer to the sticker listing the tyre pressures on the fuel filler flap). It may also be necessary to adjust the tyre pressures on the trailer according to the recommendations of the trailer manufacturer.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the standard mirrors. If this is not the case you should have additional mirrors fitted. Both exterior mirrors should be mounted on hinged extension brackets. Adjust the mirrors to give sufficient vision to the rear.
Headlights
Before starting a journey, check the headlight beam settings with the trailer hitched up. Adjust the headlight settings if necessary.
If the car is equipped with manual headlight range control, you only need to turn the adjuster control as required, see Link.
The headlight beam settings will be adjusted automatically if your Audi A1 is equipped with dynamic headlight range control*.
Power supply
The power supply to the trailer is interrupted when the ignition is switched off and while the engine is starting.
Removable ball joint coupling
On Audi A1s with a towing bracket obtained from Audi Genuine Accessories, the ball joint coupling is removable. It is stowed in the storage compartment underneath the floor panel together with the necessary fitting instructions.
Note
We recommend having the car serviced between the normal inspection intervals if it used frequently for towing a trailer.
