Trailer loads
! Use a drawbar noseweight as close as possible to the maximum permissible noseweight.
Do not use a noseweight of less than 50 kg, as the vehicle/trailer combination may other-
wise become unstable. Note that the payload and the rear axle load are reduced by the
actual noseweight.

S 400 HYBRID

dient-climbing capability of 8% from a standstill).
Permissible trailer load, braked (at a minimum gra-
dient-climbing capability of 12 % from a standstill).
Maximum drawbar noseweight (the drawbar nose-
weight is not included in the trailer load)
However, the actual noseweight must not exceed the value given on the trailer tow hitch
identification plate. In addition, a distinction should be made between towing a trailer and
using a carrier system on the ball coupling of the trailer tow hitch.
Note also that the payload and the rear axle load are reduced by the actual noseweight.
You can attach carrier systems, e.g. bicycle racks or load-bearing implements, on the ball
coupling. The maximum noseweight of 75 kg applies when using carrier systems on the ball
coupling.
