NOTE
The maximum radar range is approximately 500 feet (150 meters). Rain, snow, fog, ice and other severe
weather conditions may affect the performance of the ACB system and shorten radar range.
As part of your pre-trip vehicle inspection, check to see that there is no mud, snow, ice build-up or other
obstruction in front of the radar sensor. You should inspect the radar sensor mounting and remove any
obstruction that may impair the sensor functioning.
DRIVER WARNINGS
Before using the ACB, the driver should fully understand all the audible and visual warnings that the system
provides. Any audible warning (beeping or tone) means that your vehicle is too close from the vehicle ahead.
DASHBOARD TELLTALE
When ACB is turned on and a cruise speed is set, if the forward vehicle is detected (in range) by the radar, the
FORWARD VEHICLE DETECTED telltale light will illuminate. This is an indication to the driver that the forward
vehicle is being tracked, that the ACB is actively managing the distance between the coach and the vehicle
ahead and that the ACB system may automatically intervene to maintain the set following distance. There are
three types of warnings with this telltale light.
FORWARD VEHICLE
DETECTED telltale light
SPEEDOMETER LED
With the cruise control engaged and a cruise speed set, a green LED illuminates above the cruise control set
speed on the speedometer.
FIGURE 34: THE CRUISE SET SPEED IS 80 KM/H
With a cruise speed set, the vehicle ahead slows moderately. The system will display to the driver the
approximate speed of the vehicle ahead with yellow LEDs above the speedometer.
