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

Obser vethefo llowing foryo ur ow n sa fety
and that of other road users: #

Driving and parking

Depending on
the bicycle rack 's design, up to
th re e bicycles can be transpor ted on the bicycle
ra ck.
When mounted on ball head 1and guide pin
2, 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 change
when a bicycle rack isfitted:
R The vehicle is heavier.
R The acceleration and slope-climbing ability is
restricted.
R The braking di stance is lon ger.
This can 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 (→ page 430).
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 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 or rech arge able bat teries, before
loading them onto the bicycle rack . This
impr ovesth e wind resis tance and centre of gr av‐
ity of the bicycle rack.
Alw ays secure the bicycles toprev ent them from
moving around and check they are secured 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 wind resis tance and
load on the trailer hitch increase. Driving and parking
