ACTIVATING THE ACB
Activation of the Adaptive Cruise with Braking is similar to the regular cruise control activation. Press the
ON/OFF cruise control toggle button (CC) on the steering wheel keypad, the ACB "ON" status pictogram will
appear in the DID.
Accelerate the vehicle to the desired cruising speed and then, press the SET button on the keypad. The ACB
"ON" with set speed confirmation status pictogram will appear in the DID.
ACB is now engaged with the set following distance and driver warning features. Whenever the cruise control
is engaged, the ACB is also engaged. You cannot engage the cruise control alone, without engaging the ACB
features.

MAINTAINING A SET FOLLOWING DISTANCE
Using a radar sensor mounted to the front bumper, the ACB system measures the distance between the
coach and the forward vehicle and intervenes to help maintain a safe set following distance behind the
vehicle. This feature engages automatically once the driver turns on and sets cruise speed.
Following distance refers to the time gap, measured in seconds, between the coach and the vehicle ahead.
The actual physical distance between the coach and the vehicle ahead will vary based on your set cruise
speed; although the set time gap remains the same for all set cruise speeds. Prevost's default set time gap is
1.7 seconds.
