FOLLOWING DISTANCE ALERT (FDA)

Following Distance Alert is always active whenever the coach is moving to a speed greater than 36 mph (58
km/h), whether or not ACB is turned on.
Following Distance Alert provides both audible and visual warnings whenever the distance between the coach
and the forward vehicle is less than the set distance and getting closer. Once the audible warning is given, the
driver must increase the distance between the coach and the vehicle ahead until the audible warning stops or
maneuver clear of the forward vehicle.
WARNING
Active interventions of ACB to maintain safe following distance (throttle reduction, engine brake application,
service brakes application) are only operational when the ACB is engaged with a cruise speed set.
IMPACT ALERT (IA)
Impact Alerts are always operational when the vehicle is moving above 15 mph (24 km/h) whether or not ACB is
turned on.
The Impact Alert warning is the most severe warning issued by the ACB system. This alert indicates that the
driver must take immediate evasive action by applying more braking power and/or steering clear of the vehicle
ahead to potentially avoid or lessen the severity of a collision. Collision Mitigation Braking CMB applies
vehicle braking to help avoid or lessen the severity of a collision with a forward vehicle.
The Impact Alert is also applicable to stationary metallic objects such as stopped or stalled vehicles. This alert
provides a warning given up to 3.0 seconds before a potential collision with a stationary metallic object in the
coach's lane of travel. The driver can either slow down or maneuver in an attempt to avoid the object.
The Impact Alert will only warn and will not actively decelerate or brake the coach when approaching stationary
objects.
