2021 MERCEDES-BENZ E-CLASS SALOON ECU

The
following bicycle rack designs are possible:
R When mounted byattaching toball head 1,
th e maximum load capacity is 75 kg. You can
transport up tothre e bicycles.
R When mounted on ball head 1and guide pin
2, the maximum load capacity is 100 kg. Yo u
can transport up tofour bicycles.
The maximum load capacity is calculate d fromthe
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 172).
When using a bicycle rack , set the tyre pressure
fo r increased load on there ar axle of theve hicle.
Fu rther information on the tyre pressure can be
fo und in the tyre pressure table (/ page 397).

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-
gitudinal axis
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
the bicycle rack

and ball head
2 Horizontal distance between centre of grav ity
and ball head
