When the vehicle must be braked manually
If the truck catches up with a vehicle that is travelling
so slowly that
ACC
cannot manage to brake
sufficiently, a collision warning occurs: the symbol in
the instrument lights up and all the LEDs in the
speedometer turn red. At the same time, a signal is
sounded. Use the footbrake to reduce the speed
sufficiently!

Caution!
The ACC may identify a vehicle
that is very close to the
identification area, e.g. in an
adjacent lane. This may result in
unexpected braking of your truck.
Brake protection
To protect the wheel brakes from over-use, there is a
built-in protection which limits the use of the wheel
brakes.
ACC
then temporarily changes to reduced
capacity.
The “
ACC
reduced” symbol informs that
ACC
has
changed to only use the auxiliary brakes and that the
braking capacity for
ACC
is reduced.
Note!
If the connected trailer has no ABS
or has a faulty ABS, the system goes
to reduced capacity.
