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 75 kg. The maximum load capacity is calculated from
the
we ight of the bicycle rack and the bicycle rack
load.
Obser vethe no tes on driving with a roof load,
trailer or fully laden vehicle (/ page 152).
When using a bicycle rack , set the tyre pressure

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 lon-

Mercedes-Benz recommends removing all de tach-
able parts from bicycles (e.g. bask ets, ch ild seats,
re ch arge able batteries) before loading them onto
th e bicycle rack . This will impr ovethe aerody- namic
resis tance and centre of grav ity of the bicy-
cle rack.
Alw ays secure the bicycles toprev ent them 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 driving
ch aracteristics and rear view may be impaired. In
addition, aerodynamic resis tance and the load on
th e trailer hitch will increase. Load distribution on
