Trailer assist display
Make sure that the dark indicator is correctly
aligned with the trailer orientation. It may not
be possible to detect the correct steering angle
in poor visibility or on heavily structured surfa-
ces.
It is only possible to switch the trailer assist
on/off when the vehicle is stationary or driving
forwards at no more than 10 km/h.
When you switch on the system, the display
shows the picture from the reversing camera
with a sector 1 and a dark indicator 4 . The dark
indicator shows the current orientation of the
trailer; the sector indicates the possible adjust-
ment range of the articulation angle. When re-
verse gear is engaged, the current articulation
angle setting is indicated by a light indicator 2 .
The white markings 3 indicate the area in which
the vehicle and trailer would be travelling in a
straight line.

Press to switch off the trailer assist.
Long trailers with a large distance between the
trailer axle and the vehicle reach larger articula-
tion angles than short trailers while in motion.
They therefore react with a greater delay.
When reversing with a trailer, the articulation an-
gle gradually changes as more distance is cov-
ered. If you want to drive in a straight line again,
it is advisable to first make a forward movement
in order to straighten up the trailer.

Initialising the trailer
If the trailer was hitched up with a large articula-
tion angle or if automatic initialisation has not
yet been performed, it will be necessary for the
system to initialise the trailer. When the vehicle
is reversing, this process is indicated by a smaller
sector as soon as the trailer starts moving. In ad-
dition, the centre display shows the message
Drive carefully and operate brakes yourself to
initialise trailer.

tion angle to zero and drive straight ahead with
the trailer. If the articulation angle is wide, the
system first suggests making a corrective
movement forwards. In this case, the vehicle
will also steer when driving forwards. If the
dark indicator is within the white markings, the
trailer’s direction of travel can be maintained. If
the indicator is outside the markings, the trail-
er will not drive straight ahead again until a cer-
tain distance has been travelled. In this case, it
may be necessary to correct the orientation.
To initialise the trailer, the vehicle must be slowly
driven forwards in a straight line and through
several corners to reduce the articulation angle.
During the initialisation procedure, the system is
available with limited functionality.
The initialisation process can take longer, de-
pending on outside conditions such as poor light
conditions, etc.
