Volvo FH - Driving at Low Speed

J203149
When
ACC
is permitted to use the wheel brakes again,
the symbols to the right are shown:
How long time it takes until
ACC
permits the use of
the wheel brakes again depends among other things on
how much the driver uses the footbrake during the
time the
ACC
has reduced the brake capacity.
If the brake protection is activated at the same time as
the
ACC
brakes for a slower vehicle, the system will
warn the driver (compare with collision warning).
Thereafter the system temporarily goes over to
reduced
ACC
.
Caution!
When
ACC
is in the reduced
mode, the ACC has reduced
braking capacity.
Note!
Economic use of
ACC
on downhill
slopes behind slower vehicles
reduces the risk of the brake
protection being activated and that
ACC
goes to reduced mode.
Driving at low speed
When driving at very low speeds,
ACC
is
automatically disengaged . The symbol to the right is
then shown. See chapter "Cruise control" for more
information.
E.g. this can occur when driving in a slow moving
queue.
