using the bicycle rack incor rectly
The bicycle rack may become de tach ed from
th eve hicle in thefo llowing cases:
R the permissible load capacity of the
trailer hitch is exceeded.
R the bicycle rack is used incor rectl y.
R the bicycle rack is secured tothe ball
neck beneath the ball head.
Obser vethefo llowing foryo ur ow n sa fety
and that of other road users: #

Depending on
the bicycle rack 's design, up to
th re e bicycles can be transpor ted on the bicycle
ra ck.
When mounted byattaching toball head 1,the
maximum load capacity is 75kg.
The load capacity is calculated from thewe ight
of the bicycle rack and the bicycle rack load.
The vehicle's driving characteristics will change
when a bicycle rack isfitted. Adapt your driving st
yle according ly. Drive carefully and maintain a
sa fe dis tance.
When using a bicycle rack , set the tyre pressure
fo r maximum loading on there ar axle of the
ve hicle. Further information on the tyre pressure
can be found in the tyre pressure table
(/ page 333).
Note s on loading
The lar gerth e dis tance between the load's
cent reof gr avity and the ball head, the greater
th e load on the trailer hitch.
Therefore, obser vethefo llowing no tes:
R mount heavy bicycles as close totheve hicle
as possible
R always distribute the load on the bicycle rack
as evenly 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
the bicycle rack

ity and ball head
