Functions and activation conditions
ATTENTION ASSIST assesses your level of fati-
gue or lapses in concentration by taking the fol-
lowing criteria into account:
R
personal driving style, e.g. remaining in lane,
steering characteristics
R
journey-related parameters, e.g. length of
journey
ATTENTION ASSIST is restricted and a warning
does not occur or is delayed:
R
if you are predominantly driving slower than
60 km/h

ficult to distinguish

on the part of the driver:

Lane Keeping Assist is reactivated automati-
cally
During long journeys, take regular breaks in
good time. If you do not take a break, ATTEN-
TION ASSIST can only warn you again after
15 minutes at the earliest.

stationary for some time, ATTENTION ASSIST
resets the detection sequence.

always activated. You can deactivate/activate
ATTENTION ASSIST using the
Systems

Sideguard Assist
General notes
Sideguard Assist is only available on left-hand
drive vehicles. Sideguard Assist monitors the
area to the right of the tractor vehicle and
trailer/semitrailer using two radar sensors. The
radar sensors are mounted to the right-hand
wing bracket in front of the rear axle. Sideguard
Assist provides assistance when turning right
and changing into the right-hand lane. A warning
lamp in the warning element on the right-hand A-
pillar informs you that an object has been detec-
ted in the monitored area. A warning tone also
sounds if there is a risk of collision.
Sideguard Assist is not active while reversing.
The trailer monitoring of Sideguard Assist is not
active:
R
shortly after reversing
R
shortly after coupling up
It is not possible to switch the trailer monitoring
of Sideguard Assist on or off:
R
shortly after reversing
R
shortly after coupling up
Important safety notes
G
WARNING
When detection is restricted, Sideguard
Assist may issue a warning too late or not at
all.
In particular, the detection of obstacles can
be impaired in the following situations:
R
dirty, icy or obscured sensors
R
very wide lanes
R
vehicles not driving in the middle of their
lane
R
barriers or other road boundaries
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and maintain a safe distance at the side
of the vehicle.
Sideguard Assist is only an aid. It may fail to
detect some objects and is not a substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users, pedestrians and obstacles.
Make sure that the area to the right next to the
towing vehicle and the trailer/semitrailer is free
before you turn right.
