When using a bicycle rack , set the tyre pressure
fo r maximum loading on there ar axle of the
ve hicle. Further information on the tyre pressure
can be found in the tyre pressure table
(/ page 327).
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, rech arge able bat teries) before load‐
ing them onto the bicycle rack . This will impr ove
th e aerodynamic resis tance and centre of gr avity
of the bicycle rack. Alw
ays secure the bicycles topreve ntthem 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 driv‐
ing characteristics and rear view may be
impaired. In addition, aerodynamic resis tance
and the load on the trailer hitch will increase. Load distribution on
the bicycle rack

WARNING Risk of accident from driving
wi th sealed tyres
A tyre temp orarily sealed with tyre sealant
impairs the handling characteristics and is
not suitable for higher speeds. #
Adapt your driving style according lyand
drive carefull y. #
Do not exceed the maximum speed
limit with a tyre that has been repaired
using tyre sealant. #
Obser vethe maximum permissible speed for
a tyre sealed with tyre sealant 80 km/h.
