If the load on the front axle is reduced when
pulling away on a steep uphill slope, the front
wheels have a tendency to spin. 4ETS recog-
nises this and brakes the wheels accordingly. The rear wheel torque is increased and it is
easier to pull away.

ent-climbing capability, see (Y page 180).Trailer tow hitch
Trailer loads
Trailer loads, noseweights and axle
loads !
Use a drawbar noseweight as close as pos-
sible to the maximum permissible nose-
weight. Do not use a noseweight of less than
50kg, otherwise the trailer may come loose.
Note that the payload and the rear axle load
are reduced by the actual payload.

The actual drawbar load may not be higher than
the specified value. The value can be found on
the trailer tow hitch or trailer identification
plates. The lowest weight applies.
You can attach carrier systems, e.g. bicycle
racks or load-bearing implements, to the ball
coupling. The maximum payload of 75 kg applies
when using carrier systems on the ball coupling. Trailer tow hitch
