from the yellow coupling head (4) –
yellow.
• Remove the plug (5) of the trailer electrical
system from the socket.
• If necessary, remove the plugs (2) and (3)
from the sockets (ABS and special fittings).
Uncoupling the
trailer
• Secure the trailer with the (trailer) parking
brake and chocks as prescribed to prevent it
from rolling away.

the trailer.
G
Risk of accidents due to trailer moving unintentionally
Always first remove the hose from the supply line so that the trailer is
braked. This prevents the trailer moving when you remove the brake hose.
G
Risk of injury when the automatic closing device is triggered
Never put your hand into the coupling jaw when the towbar coupling is
open.
This prevents the coupling closing automatically, and the cotter pin causing
serious injury to your hand.
