Towage of the trailer
The factory complete set of the car the traction coupling device provides also all necessary for operation of the trailer according to technical and standard requirements.
For electric connection of the car and the trailer the car is completed with the 13-contact plug socket. In the presence on the trailer of a 7-contact plug fork it is possible to use the corresponding cable which is available at the Audi enterprises the adapter.
Additional installation of the traction coupling device has to conform to requirements of the manufacturer of this device.
Remember the admissible maximum mass of the towed freight, see Specifications.
The mass of the towed freight
Do not exceed the admissible maximum mass of the towed freight at all.
If the most admissible mass of the trailer is not used completely, it is possible to overcome rises with the bigger size of a bias.
Standard values of mass of the towed freight are valid only at the height up to 1000 m above sea level. With increase in height the sparseness of air raises and respectively the engine capacity and, as a result, ability to overcoming of rises decreases. Therefore the standard mass of the road train decreases by 10% for each 1000 m of rise. The mass of the road train is equal to the sum of mass (loaded) car and (loaded) trailer.
The data on basic loading specified in a name plate of the trailer are its control sizes. Data which can be lower than these sizes, can be found in registration documents of the car or in Specifications.
Placement of freight
Distribute freight of the trailer so that the heaviest subjects settled down whenever possible closer to its bridge. Besides, fix freight not to allow its shift at the movement.
Use the permissible basic load transferred to a spherical head through dyshlo the trailer whenever possible completely, but do not exceed.
Pressure in tires
Install pressure in car tires corresponding to its full load see the plate of pressure of air in tires on a door rack. If necessary modify also pressure of air of tires of the trailer according to recommendations of his manufacturer.
If serial rear-view mirrors do not provide a sufficient rearview, it is necessary to establish additional external mirrors. Both external mirrors have to fasten on the put arms. So adjust the provision of mirrors that the sufficient rearview was provided.
Prior to the movement with the trailer check and if necessary modify installation of headlights by means of the device of regulation of a tilt angle of headlights, see Lighting and providing the review.
Removable spherical head
The removable spherical head of the traction coupling device of a factory complete set is together with the installation guide in a niche of a spare wheel of a luggage carrier.
To the instruction but driving
The movement with the trailer demands extra care.
Distribution of loading
At the empty car and the loaded trailer distribution of loading is extremely adverse. In need of the movement in this option the movement has to be especially slow.
With increase in speed dynamic properties of the road train worsen. Therefore under adverse road, weather and aerodynamic conditions do not use the maximum speed allowed by traffic regulations. It especially concerns the movement under a bias.
At once reduce speed at the slightest signs of wagging of the trailer. Do not try "to level" the road train increase in speed at all.
Brake in due time! At towage of the trailer with inertial brake system brake in the beginning softly, and then smoothly. It will help to avoid pushes the blocked trailer wheels. For use of possibility of braking by the engine, in due time switch to a low gear.
The stabilizing adaptations reduce fluctuations of the trailer of rather cross axis and its wagging. It is recommended to apply them with a considerable mass of the trailer.
Watch indication of temperature of cooling liquid at very high external temperature and the movement on long rise on a low gear and with high frequency rotations of a shaft of the engine, see Governing bodies and devices. When calling an arrow on the right part of a scale at once reduce speed. At a blinking in a control panel of an alarm lamp stop and cool the engine, having allowed it to work as some minutes idling.
Removable traction coupling device
Installation and dismantle of the traction coupling device demands accuracy.
The removable spherical head of the traction coupling device is under a luggage carrier flooring.
For installation and dismantle of a spherical head enough normal muscular efforts of hands.
Use of hinged components / autoaccessories on the traction coupling device
Remember that when using the improper hinged components mounted on the traction coupling device (for example, an arm for the bicycle), perhaps hidden damage of a spherical head that in an extreme case can lead to destruction of the traction coupling device during towage of the trailer.
Never deblock a spherical head at the attached trailer.
At the movement without trailer remove a spherical head and check correctness of closing by a cover of a fixing nest.
When cleaning the car the steam-ejecting pump remove previously spherical head and check correctness of closing of a fixing nest a cover.
Installation of a spherical head (first stage)
Continuation, see. "Installation of a spherical head (second stage)".
Installation of a spherical head (second stage)
The preliminary tightness is provided with performance of the following conditions:
The spherical head can be established only with a preliminary tightness.

Continuation, see. "Installation of a spherical head (fourth stage)".
Installation of a head (fourth stage)
Correctness of fastening is provided with performance of the following conditions:
At non-performance of above-mentioned conditions repeat installation.
Dismantle of a spherical head
Points of fastening of the traction coupling device
Four points of fastening (A) of the traction coupling device are from the lower party of the car.
The minimum distance (B) between a bumper and a spherical head has to make 65 mm. The distance (C) between the back bridge and a spherical head has to make 1056 mm.
