The maximum articulation angle depends on
th e length of the trailer. This is calculated by
th e sy stem bydriving theve hicle forw ards,
including cornering. Before the length of the
trailer has been calculated, the maximum
articulation angle is appr oximately 23°. The
longer the trailer is, the higher the maximum
articulation angle (max. appr oximately 60°).

Alw ays distribute the load on the bicycle rack
as eve nly as possible across theve hicle's
longitudinal axis.
Mercedes-Benz recommends removing all
de tach able parts from bicycles (e.g. bask ets,
ch ild seats, rech arge able bat teries) before load‐
ing them onto the bicycle rack . This will impr ove
th e aerodynamic resis tance and centre of gr avity
of the bicycle rack.
Alw ays secure the bicycles topreve ntthem from
moving around and check them at regular inter‐
va ls to ensure that they are secure.
Do not use tarp aulins or other co vers. The driv‐
ing characteristics and rear view may be
impaired. In addition, aerodynamic resis tance
and the load on the trailer hitch will increase. Load distribution on
