% The maximum articulation angle depends on
t

he length of the trailer. This is calculated by
the system by driving the vehicle forwards,
including cornering. Before the length of the
trailer has been calculated, the maximum
articulation angle is approximately 23°. The
longer the trailer is, the higher the maximum
articulation angle (max. approximately 60°). Using Trailer Manoeuvring Assist

level may be changed unintentionally, e.g. by
other persons. You may become trapped if you
couple up or uncouple a trailer while the vehi-
cle level is changing. In addition, other people
could become trapped if their limbs are
between the vehicle body and the tyres or
underneath the vehicle.
When coupling up or uncoupling a trailer,
make sure that:

t
he vehicle in the following cases:
= the permissible load capacity of the trailer
hitch is exceeded.
= the bicycle rack is used incorrectly.
= the bicycle rack is secured to the ball neck
beneath the ball head.
Observe the following for your own safety and
that of other road users:
= always adhere to the permissible load
capacity of the trailer hitch.
= always observe the permissible rear axle
load of the towing vehicle.
= use the bicycle rack only to transport bicy-
cles. =
alw
ays mount the bicycle rack properly by
attaching to the ball head and the ball
neck guide pin, if possible.
= when transporting four bicycles, always
use bicycle racks that have additional sup-
port on the ball neck guide pin.
= use only bicycle racks approved by

Mercedes-Benz recommends removing all detach-
able par ts from bicycles (e.g. baskets, child seats,
rechargeable batteries) before loading them onto
the bicycle rack. This will improve the aerody-
namic resistance and centre of gravity of the bicy-
cle rack.
Always secure the bicycles to prevent them from
moving around and check them at regular inter-
vals to ensure that they are secure.
Do not use tarpaulins or other covers. The driving
characteristics and rear view may be impaired. In
addition, aerodynamic resistance and the load on
the trailer hitch will increase. Load distribution on the bicycle rack
1 Vertical distance between centre of gravity
and ball head
2 Horizontal distance between centre of gravity
and ball head
3 The centre of gravity is on the vehicle's centre
axis
