maximum permissible speed of your trailer. In
Germany, the maximum permissible speed is
80 km/h (100 km/h in exceptional cases).
the trailer tow hitch is one of the most impor-

If you do not require the ball coupling, remove
it from the ball coupling recess.
You can obtain information on the installation of
trailer electrics at any qualified specialist work-
shop.

of the vehicle. If this is case, use a trailer with a
height-adjustable trailer drawbar.
