The factory complete set of the car the traction coupling device provides also all necessary for trailer operation 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. At existence on the trailer of a 7-contact plug fork it is possible to use the corresponding cable available at the Audi enterprises the adapter.
Additional installation of the traction coupling device should correspond to requirements of the manufacturer of this device.
Remember admissible maximum mass of towed cargo, see. Specifications.
Mass of towed cargo
At all do not exceed admissible maximum mass of towed cargo.
If the most admissible mass of the trailer is not used completely, it is possible to overcome liftings with bigger size of a bias.
Standard values of weight of towed cargo are valid only at height to 1000 m above sea level. With increase in height the razrezhennost of air raises both respectively engine capacity and, as a result, ability to overcoming of liftings decreases. Therefore the standard mass of a road train decreases for 10 % for each 1000 m of lifting. The mass of a road train is equal to the sum of mass (loaded) car and (loaded) trailer.
Data on the basic loading, specified in the factory plate of the trailer, are its control sizes. Given which can be lower than these sizes, it is possible to find in registration documents of the car or in Specifications.
Cargo of the trailer distribute so that the heaviest subjects settled down whenever possible closer to its bridge. Besides, fix cargo not to allow its shift at movement.
The permissible basic load transferred to a spherical head through дышло of the trailer, use whenever possible completely, but do not exceed.
Pressure in tires
Establish pressure in the 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 the sufficient back review, it is necessary to establish additional external mirrors. Both external mirrors should fasten on put arms. So adjust the provision of mirrors that the sufficient back review was provided.
Prior to the beginning of 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 review.
Demountable spherical head
The demountable spherical head of the traction coupling device of a factory complete set is together with an erection manual in a niche of a spare wheel of a luggage carrier.
To the instruction but driving
Movement with the trailer demands extra care.
At the empty car and the loaded trailer loading distribution is extremely adverse. In need of movement in this option movement should be especially slow.
With increase in speed dynamic properties of a road train worsen. Therefore under adverse road, weather and aerodynamic conditions do not use the maximum speed resolved by traffic regulations. It especially concerns movement under a bias.
At once reduce speed at the slightest signs of wagging of the trailer. Do not try to "level" at all a road train increase in speed.
Brake in due time! At trailer towage with inertial brake system brake in the beginning softly, and then smoothly. It will help to avoid pushes the blocked wheels of the trailer. For use of possibility of braking by the engine, be in due time switched to a low gear.
Stabilizing adaptations reduce fluctuations of the trailer of rather cross-section axis and its wagging. It is recommended to apply them at considerable mass of the trailer.
Watch indication of temperature of cooling liquid at very high external temperature and movement on long lifting on a low gear and with high frequency of rotation of a shaft of the engine, see. Governing bodies and devices. When calling 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, let's to it work as some minutes idling.
Demountable traction coupling device
Installation and dismantle of the traction coupling device demands accuracy.
The demountable 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 a bicycle), probably hidden damage of a spherical head that in an extreme case can lead to traction coupling device destruction during trailer towage.
Never deblock a spherical head at the attached trailer.
At movement without the trailer remove a spherical head and check correctness of closing by a cover of a fixing nest.
When cleaning car by the steam-ejecting pump remove previously a spherical head and check correctness of closing of a fixing nest a cover.
Installation of a spherical head (the first stage)
Continuation, see. «Installation of a spherical head (the second stage)».
Installation of a spherical head (the second stage)
The preliminary tightness is provided with performance of the following conditions:
It is possible to establish a spherical head only with a preliminary tightness.

Head installation (the fourth stage)
Correctness of fastening is provided with performance of the following conditions:
At default 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 bottom party of the car.
The minimum distance (B) between a bumper and a spherical head should make 65 mm. The distance (C) between the back bridge and a spherical head should make 1056 mm.
