Decreasing set speed
The vehicle cruise speed setting can be
decreased by one of the following methods.
1. Press and hold the SET button until the
desired cruising speed is reached. When the
SET button is released, the new cruising
speed will be stored in the cruise control
memory.
or
2. Each brief pressing of the SET button will
decrease set cruising speed by 1 mph
(2 km/h).
or
3. Slightly apply the service brake and when
desired cruise speed is reached, press and
release the
SET button.
Canceling the preset speed
You can cancel the preset cruising speed by:
1. Pressing momentarily the CANCEL button;
2. Depressing the brake pedal.
Resuming Set Speed
If the preset speed is cancelled by pressing the
CANCEL button or depressing the brake pedal,
pressing the RES (RESUME) button will restore
the speed set prior to cancellation, providing that
your speed is above 30 mph (50 km/h).
NOTE
When driving downhill with the cruise control
on and set, the engine brake or the
transmission retarder engage automatically (if
previously activated) when the selected cruise
speed is exceeded by approximately:
•
4 mph (7 km/h) with the engine brake
activated;
•
0.6 mph (1 km/h) with the transmission
retarder activated.
The engine brake or the transmission retarder
is then disengaged when speed has returned
near to selected cruise speed.
The engine brake will provide low braking
power or high braking power depending on
which of the two steering wheel engine brake
control buttons is activated;
= engine brake low
= engine brake high
The transmission retarder maximum braking
level is determined by the retarder hand lever
position on the steering wheel.
NOTE
To avoid sudden vehicle hesitation, slightly
depress the accelerator pedal before
disengaging the cruise control.
NOTE
When the cruise rocker switch is released,
the cruise control is completely shut off and
the cruise speed setting is erased from the
cruise control memory.
IMPORTANT NOTE
If the engine was stopped and the cruise
rocker switch was in the on position, the
rocker switch must be reset by turning it off
then on again in order for the cruise control to
be reactivated.
WARNING
Do not use the cruise control when driving
speed must be constantly adjusted, such as in
heavy traffic or on winding, icy, snow-covered
or slippery roads, or on gravel roads.
WARNING
Do not put the transmission in the neutral (n)
position while driving with cruise control. This
may cause the engine to over-speed and
result in a loss of driving control.

ADAPTIVE CRUISE
BRAKING
Prevost AWARE Adaptive Cruise Braking (ACB)
is an optional cruise control that not only
maintains the set speed, but will also intervene,
as needed, to help the driver maintain a set
following distance behind the forward vehicle by
reducing speed as necessary. As soon as the
forward vehicle is at a safe distance, the coach
will accelerate back to the cruise set speed.
