Special Road Situations

Certain road situations may affect the system's ability
to detect objects. These situations include the effects
of curves, dips, and hills which can provide an unex-
pected result.
NOTE: A warning may sound when an object is
detected in front of the vehicle even though the
driver intends to turn away or stop before reach-
ing the object.
•
When an object is detected in a very sharp
right- or left-hand turn, the audible alarm will
not sound.
•
When approaching a curve, alarms may sound
and lights illuminate, because of an object off
the road directly in line with your vehicle. This
will not occur when the brakes are applied.
•
When approaching a roadway descending to a
lower elevation, elevated obstacles such as
overpasses and overhead signs may be de-
tected.
•
Vehicles cannot be detected on the other side
of a hill. An alarm will not sound until the object
is within the antenna assembly's field of view.

•
Heavy rain or water spray at the side sensor may
cause both the yellow and red lights on the side
sensor display to illuminate at the same time.
Under these conditions the system is temporarily
unable to provide adequate warnings.
Failure to drive safely and use the system prop-
erly could result in personal injury and/or death
and severe property damage.
Maintenance
Keep the antenna and side sensor free of buildup of
mud, dirt, ice, or other debris that might reduce the
system's range.
Failure Display Mode/Fault Codes
The VS-400 performs internal diagnostics at power-
up, then continuously monitors system components
thereafter.
If a failure is detected, depending on what features
are affected, the DIU displays a screen similar to
Fig. 6.15, blinks the orange fault light, and sounds a
tone. Press the OK button to acknowledge the fault.
After the fault has been acknowledged, the DIU will
attempt to return to normal operations. The orange
LED is continuously illuminated while the fault per-
sists. If the fault disappears, the VS-400 transmits a
On approaching a steep hill, objects above the
beam cannot be detected. Generally, the beam
hitting the road surface does not cause an
alarm.
The side sensor only detects objects within its
field of view, next to the tractor. A vehicle be-
hind the field of view will not be detected.
The side sensor range is set to detect
average-sized vehicles 2 to 10 feet (0.5 to 3
meters) away in the adjacent lane.
The radar beam will detect near range cut-ins
of approximately 30 feet (9 meters) or less,
depending on the angle of entrance into the
lane in front of your vehicle.
A continuous fixed object on the right side of
the vehicle such as a guard rail, wall, tunnel, or
bridge may cause the side sensor alert light to
stay on.
