• The installation of tow hitches must comply with the regulations of the country in question. The standard is DIN 74 050 in Germany.
• Observe spacing dimensions*. The standard is DIN 74 058 in Germany.
• In the event of deviations from the accident prevention regulations, a certificate of exemption and approval must be requested in the Federal Republic of Germany from the professional association with liability for industrial safety assurance with regards to vehicle ownership, 22757 Hamburg (tel. +49 40/38 10 91).
• If tow hitches are installed retroactively, only the makes and types approved by us and genuine Volkswagen cross member carriers may be used. Provision is already made for attachment points in our cross member carriers and/or longitudinal members.
• The size of the tow hitch is determined in accordance with the D value.

D = A-frame
m_k = Max. permissible weight of pulling vehicle (Kfz) in t
m_a = Max. permissible weight of trailer in t
g = 9.80665 m/s²

The permissible trailer load can be gleaned from the official sales documents or the trailer operation guide. In order that trailers can be exchanged for border crossing traffic, the spacing dimension x must be max. 300 mm.

* Where the base is extremely low down or the overhang large, and also following overhang extensions, the use of a tow hitch may not be possible. For this reason, the structural criteria must first be established.

Jaw-type coupling (ca be ordered direct from factory via PR no.1D5)

• Spacing from centre of coupling pin of tow hitch to end of body structure max. 420 mm. Maintain clearances.
• In exceptional circumstances, the spacing of 420 mm can be exceeded: Spacing maximum 650 mm on vehicles with tipping bodies or assemblies attached to the rear. Spacing of maximum 1320 mm if height clearance from ground to lower edge of body is at least 1150 mm. A suitable remote operating device for the coupling must be provided. Safe operation of the coupling must not be impaired.

Fifth wheel coupling (can be ordered ex-factory via PR no. 1D1/1D2/1M0/1M4)

• Adhere to clearances.
• Installation only on type approved trailer bracket.
• Installation on underbody protection only is not permissible. Modifications to the underbody protection must be agreed upon with the Vehicle Inspectorate or technical inspection authority.
