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

Obser vethefo llowing foryo ur ow n sa fety
and that of other road users:
R always adhere tothe permissible load
capacity of the trailer hitch. Driving and parking

R
only use the bicycle rack totranspo rt

bicycle rack s being used incor rectly #
Only use bicycle rack s appr ovedby
Mercedes-Benz. Depending on
the bicycle rack 's design, up to
th re e bicycles can be transpor ted on the bicycle
ra ck:
R when moun tedby attaching toball head 1,
th e maximum load capacity is 75kg.Up to
th re e bicycles can be transpor ted.
The load capacity is calculated from thewe ight
of the bicycle rack and the bicycle rack load. The
vehicle's handling characteristics change
when a bicycle rack isfitted. The vehicle:
R is heavier
R isrestricted in its accele ration and gradeabil‐
ity
R has an increased braking di stance
This can impair theve hicle's handling character‐
istics. 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 390).
Note s on loads
The larger the dis tance between the load's
cent reof gr avity and the ball head, the greater
th e load on the trailer hitch.
Obser vethefo llowing no tes:
R mount heavy bicycles as close totheve hicle
as possible. 232
Driving and parking

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 the bicycles, e.g. bask ets,
ch ild seats or batteries, before loading them
onto the bicycle rack . This impr oves the wind
re sis tance and centre of gr avity of the bicycle
ra ck.
Alw ays secure the bicycles topreve ntthem from
moving around and check they are secured at
re gular inter vals.
Do not use tarp aulins or other co vers. The han‐
dling characteristics and rear view may be
impaired. In addition, the wind resis tance and
load on the trailer hitch increase. Distribution of
the load on the bicycle rack
