When working on or around a vehicle, the following guidelines should be observed AT ALL TIMES:
▲Park the vehicle on a level surface, apply the
parking brakes and always block the wheels.
Always wear personal protection equipment.
▲Stop the engine and remove the ignition key
when working under or around the vehicle.
When working in the engine compartment,
the engine should be shut off and the ignition
key should be removed. Where circumstances
require that the engine be in operation, EXTREME
CAUTION should be used to prevent personal
injury resulting from contact with moving,
rotating, leaking, heated or electrically-charged
components.
▲Do not attempt to install, remove, disassemble
or assemble a component until you have read,
and thoroughly understand, the recommended
procedures. Use only the proper tools and
observe all precautions pertaining to use of those
tools.
▲If the work is being performed on the vehicle’s
air brake system, or any auxiliary pressurized air
systems, make certain to drain the air pressure
from all reservoirs before beginning ANY work
on the vehicle. If the vehicle is equipped with a
Bendix®AD-IS®air dryer system, a Bendix®DRM™

IMPORTANT SAFETY INFORMATION
The driver is always responsible for the control and safe operation of
the vehicle at all times. The Bendix™VORAD®VS-500™system does
not replace the need for a skilled, alert, professional driver, reacting
in a timely manner, and using safe driving practices.
Before driving with the VS-500 system, the driver must fully understand
all audible alerts and visual indicators.
The VS-500 system reacts ONLY to vehicles moving in the same
direction as your vehicle. The system DOES NOT recognize side-to-
side moving traffic, or oncoming traffic. The system WILL NOT slow
your vehicle or provide an alert when approaching vehicles in these
circumstances.
Pedestrians, Animals, Non-metallic or Limited-metallic Objects– The
VS-500 system will not warn or react to pedestrians, animals, and
non-metallic objects. The system may not warn or react to limited-
metallic objects (such as recreational vehicles, horse-drawn buggies,
motorcycles, logging trailers, etc.).
Metallic objects that the radar may detect in or close to the vehicle’s
path (such as crash barriers, guard rails, construction zone barricades,
tunnel entrances, etc.) may decrease the function of the radar.
Inspect the radar and mounting bracket regularly and remove any
mud, snow, ice build-up, or other obstructions. Installing aftermarket
deer guards is not recommended, and could impair the operation of
the radar.
If the bumper and/or radar are damaged or misaligned, or if the radar
was tampered with, do not use the cruise control until the vehicle is
repaired and the radar re-aligned.
If a problem is detected with the VS-500 system, there is an audible
alert, and/or icon on the Driver Interface Unit (DIU™). Depending on
the type of problem, the system may disable cruise control functions
until service is performed.
Approach grades normally, with the appropriate gear selected and at
a safe speed. Cruise control should NOT be used on steep downhill
grades.
Smaller forward vehicles, such as motorcycles, may be difficult for the
radar to identify. It is the driver’s responsibility to be aware of this
type of vehicle and to be cautious.

System Features
The Bendix™VORAD®VS-500™System is a combination of the Bendix™
SmartCruise®adaptive cruise control system and three levels of visual
and audible alerts.
SmartCruise System
The SmartCruise system maintains a set
following distance between your vehicle
and the vehicle ahead when cruise control
is set. See RADAR area in the diagram
above.
The forward looking radar locates and
tracks a moving vehicle approximately 300
feet in the same lane in front. If the vehicle
ahead slows down below the set speed on your cruise control, the system
will take the following actions as necessary:
1) Reduce the engine throttle; then
2) Apply the engine retarder.

If the vehicle ahead slows below the cruise control set speed, but then
accelerates away, the system accelerates back to the original set speed of
the cruise control. The system will again maintain a set following distance
between your vehicle and a vehicle ahead in your lane.
When the cruise control speed is set, a green cruise-enabled icon
illuminates on the Bendix™DIU™(Driver Interface Unit) display. A text
message on the DIU display provides the set speed information.
Adjustable Following Distance
Following distance refers to the time gap,
measured in seconds, between the vehicle
with a Bendix™VORAD®VS-500™system
and the vehicle ahead. The actual physical
distance between the two vehicles changes
based on the speed of each vehicle. The
time gap remains the same for all set cruise
speeds. The adjustable following distance
is set on the DIU display.
Alerts and Warnings
Visual and audible alerts and warnings are
displayed on the DIU display. All alerts
are always available, whether or not cruise
control is turned on.
The three main alerts provided by the
system are Impact Alert (IA), Following
Distance Alert (FDA), and Stationary Object
Alert (SOA).
Following Distance Alert
The Following Distance Alert (FDA) provides
both a single repeating audible tone and a
visual alert whenever the distance between
your vehicle and the detected forward
vehicle ahead is less than 1.5 seconds
(default) and the distance is decreasing.
Once the audible alert starts, increase
the distance between your vehicle and
the vehicle ahead until the audible alert
stops. If the following distance continues
to decrease, there is a double repeating
audible tone and a two LED visual alert.

2 Second Warning -
Two LEDs Illuminated
3 Second Warning -

Adjustable Following
Distance

7
Following Distance Alert (continued)
When the FDA reaches its highest level,
there is a continuously repeating audible
tone and a three LED visual alert. The FDA
is active when the vehicle is moving above
5mph (8 kph).
The Bendix™ VORAD®VS-500™FDA default is
1.5 seconds. This value may vary by fleet.
Impact Alert
The Impact Alert (IA) is the most severe
warning issued by the system. The IA alert
indicates that a collision with the detected
forward vehicle is likely and the driver must
immediately act to avoid a collision. The IA
is active when the vehicle is moving above
15mph (24 kph).
Stationary Object Alert
The Stationary Object Alert (SOA) provides
up to three (3) seconds alert time when
approaching a detected, stationary object
with metallic (radar-reflective) surfaces in
your lane. The SOA indicates that a collision
with a stationary object is likely with a single
audible tone and a two LED visual alert.
The driver must immediately act to avoid
a collision.
Be especially careful when approaching certain types of vehicles and
objects. The radar may not be able to detect objects with limited metal
surfaces (such as recreational vehicles, horse-drawn buggies, motorcycles,
logging trailers, etc). Entering a curve may reduce the alert time to less
than three (3) seconds.
The SOA is active when the vehicle is moving above 10mph (16 kph). The
SOA will sound a continuous tone and an icon appears on the DIU display.

When Not to Use Cruise Control
The Bendix™SmartCruise®adaptive cruise control system is active when
a speed is set and the cruise control is on.
Use cruise control only in recommended conditions. Do not use cruise
control when the following situations exist:
Inclement Weather – Do not use cruise control in rain, snow,
fog, ice or other severe weather conditions that may affect
the performance of the system.
Dense Traffic – Do not use cruise control in heavy traffic.
Sharp Curves and Winding Roads – Do not use cruise control
when traveling sharply curved or winding roadways.
Road curvature may impact the ability of the radar to track
vehicles ahead in the same lane.
Entrance or Exit Ramps – Do not use cruise control when
entering or exiting roadways.
Downhill Grades – Do not use cruise control on steep
downhill grades.
Construction Zones – Do not use cruise control in
construction zones.

System Maintenance and Troubleshooting
Potential False Alerts
The Bendix™VORAD®VS-500™system is one of the latest advances in
commercial vehicle technology. However, radar technology is not perfect
and false alerts occasionally occur. Radar misalignment may increase
false alerts. Take into account road conditions and other factors when
choosing how to react to system alerts.
System Warnings and Trouble Codes
The system monitors itself. If a malfunction is detected, a Diagnostic
Trouble Code (DTC) is set and the driver is alerted. The system determines
if the cruise control functions continue, or should be disabled. Service the
system as soon as possible.
Preventive Maintenance:
The VS-500 system is relatively maintenance free. The key items to keep
the system functioning properly include:
1. Keep the radar clean and free of obstructions.
NOTE: Installing aftermarket deer guards is not recommended and
could impair the operation of the radar.
2. Inspect for any damage to the bumper or the radar sensor cover,
bracket, or radar to ensure that the alignment has not been
compromised. Never use the radar unit as a step.
3. Periodically check the radar alignment.
4. Clear the cause of the trouble codes. Document trouble codes and
their causes.
Bendix safety technologies complement safe driving practices.
No commercial vehicle safety technology replaces a skilled,
alert driver exercising safe driving techniques and proactive,
comprehensive driver training. Responsibility for the safe
operation of the vehicle remains with the driver at all times.
