accelerates away, and the ACB system did
not need to use the service brakes as it
managed the intervention, the coach will
automatically accelerate back to the original
cruise control set speed, and again maintain
a set following distance behind the forward
vehicle.
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.
NOTE
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 on the dashboard 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.
FORWARD VEHICLE DETECTED telltale light
There are three types of warnings with this
telltale light:

Green: The forward vehicle is detected (in
range).

Flashing red: Collision alert. The forward
vehicle is to close to follow safely or a
metallic stationary object such as a stopped
or stalled vehicle in your lane of travel is
detected. The driver must intervene to avoid
a collision.

Solid red: ACB system malfunction. The ACB
system and the alert functions are not
available.
SPEEDOMETER LEDs
With the cruise control engaged and a cruise
speed set, a green LED illuminates above the
cruise control set speed on the speedometer.
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.

FOLLOWING DISTANCE ALERT (FDA)
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.
