Operating the automatic trailer coupling
WARNING
Danger of crushing due to unintentional actuation of the trailer
coupling!
When the trailer coupling lock is actuated, the trailer pin closes abruptly.
Limbs within the range of the trailer pin can be crushed and severely in-
jured.
► Keep all parts of the body away from the range of action of the auto-
matic trailer coupling.
► Alway keep the trailer coupling closed when it is not in use.
To ensure the prescribed swivel angle when coupled, the trailer coupling
may only be used in conjunction with drawbar lugs in accordance with
DIN 11026 (ISO 5692), DIN 74053 (ISO 1102) or DIN 74054 (ISO 8755).
Observe the maximum permissible drawbar load and trailer load: see

The permissible lugs are listed on the type label on the trailer coupling.
