WARNING Risk of an accident when
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: #
always adhere tothe permissible load
capacity of the trailer hitch. #
only use the bicycle rack totranspo rt
bicycles. #
always proper lysecure the bicycle rack
by attaching it tothe ball head. #
only use bicycle rack s appr ovedby

257

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:
R The vehicle will be heavier.
R Acceleration and slope-climbing ability will
be restricted.
R Braking di stances will be lon ger.
This may impair theve hicle's driving characteris‐
tics. Adapt your driving style accordingly. Drive
carefully and maintain a safe dis tance.
When using a bicycle rack , set the tyre pressure
fo r maximum load on there ar axle of theve hicle.
Fu rther information on the tyre pressure can be
fo und in the tyre pressure table (→ page443).
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 or rech arge able bat teries, before
loading them onto the bicycle rack . This will
impr ovethe aerodynamic resis tance and centre
of gr avity of the bicycle rack.
Alw ays secure the bicycles topreve ntthem from
moving around and check that they are secure at
re gular inter vals.
Do not use tarp aulins or other co vers. The driv‐
ing characteristics and rear view may be
impaired. In addition, the aerodynamic resist‐
ance and the load on the trailer hitch will
increase. 258
