Limitations of Collision Warning Systems
The Bendix VORAD EVT-300 Collision Warning System is intended solely as an aid
for alert and conscientious professional drivers. It is not to be used, or relied upon, to
operate a vehicle. The system should be used in conjunction with rear view mirrors
and other instrumentation to maintain safe operation. A vehicle equipped with the
EVT-300 Collision Warning System should be operated in the same safe manner
as if the EVT-300 Collision Warning System were not installed. The system is not a
substitute for normal safe driving procedures. It will not compensate for any driver
impairment, such as drugs, alcohol, or fatigue.
The Bendix VORAD EVT-300 Collision Warning System may provide little or no
warning for some hazards, such as pedestrians, animals, oncoming vehicles, and
cross traffic.
WARNING: The system will not sense objects if the sensor view is
obstructed. Therefore, do not place objects in front of the system
sensors. Remove heavy buildups of mud, dirt, ice, and other materials.
WARNING: Proper alignment is critical to correct operation of the
system.
WARNING: Be sure the vehicle is not moving during the initial self-test
conducted at vehicle start-up. If the vehicle is in motion, the system
may not operate properly. No collision warning system alerts will be
given by the EVT-300 system until all lights are extinguished after the
self-test is complete.

Overview
Bendix™ VORAD® EVT-300™ Collision Warning System
Overview
The Bendix™ VORAD® EVT-300 Collision Warning System is a sophisticated,
computerized device that uses forward-looking radar and optional side-looking radar
to constantly monitor vehicles ahead and in the blind spot area, respectively.
The collision warning system uses transmitted and received radar signals to
determine the distance and relative speed between the vehicle and objects in front.
This information is used to warn the driver of potentially dangerous situations
through visual and audible alerts. The system can perform in adverse conditions,
but objects must be within the field of view of the radar beam and must provide a
surface that can reflect the radar beam back for detection.
The optional side sensor is a radar transmitter and receiver mounted on the side
of the vehicle to detect objects from two (2) to ten (10) feet (.6 - 3 m) from the side
of the vehicle. The side sensor can detect vehicles or objects unseen by the driver,
moving or stationary, provided the vehicle or object is moving adjacent to the vehicle.
The EVT-300 system also has the ability to operate in a mode called “SmartCruise”.
The Bendix™ SmartCruise® system is an optional feature requiring installation by the
Original Equipment Manufacturer (OEM). This feature is offered as a convenience to
the driver in conjunction with the standard vehicle cruise control.
WARNING: This system does not work under all conditions and can be
deceived under certain weather types. The driver must stay alert at all
times to avoid an accident.

Component Description
Bendix™ VORAD® EVT-300™ System Components
The Bendix™ VORAD® EVT-300™ Collision Warning System is comprised of four
main components: the Antenna Assembly, Central Processing Unit, Driver Display
Unit, and the Interconnecting Harness. Two components, the side sensor and side
sensor display, are optional. Each of the components are shown in their approximate
location on a vehicle (see Figure 1 below), and their functions are described in the
following paragraphs.

Antenna Assembly
The Antenna Assembly located on the front of the vehicle, transmits and receives
low power, high frequency radar signals. The transmitted radar signals are reflected
off objects in front of the vehicle and are received back at the Antenna Assembly.
The Antenna Assembly compares the difference between the transmitted and
received signals; converts this information into a digital format; and transmits it to
the Central Processing Unit (see page 6) for additional processing. The Antenna
Assembly is usually mounted in the center of the bumper. This mounting location
ensures that the radar beam is aimed directly in front of the vehicle. The Antenna
Assembly simultaneously monitors up to 20 objects within a 350 feet (106 m) range,
whether moving or stationary.
5
Component Description
Central Processing Unit
The Central Processing Unit (CPU) is the electronic control unit for the Bendix™
VORAD® EVT-300™ Collision Warning System. The CPU and Antenna Assembly are
programmable through a slot located in the opposite end from the cable connection
on the CPU (system parameters can be set with a Pro-Link™ Diagnostic Tool or
ServiceRanger 2.8). The CPU compiles information from the Antenna Assembly,
Engine Control Unit, Speedometer, optional Side Sensor (see page 7), Brake, and
Turn Signal Circuits to produce audible and visual warnings.
The CPU can be located in a variety of places, depending upon the orientation of
the CPU inside the vehicle in which it is installed. Typical locations are on the vehicle
firewall, underneath the dashboard, or behind the driver’s seat.
Driver Display Unit
The Driver Display Unit contains controls and indicators related to system operation.
The Driver Display Unit controls system power-up, speaker volume, range for
vehicle warnings, and headway thresholds for the Bendix™ SmartCruise® system.
A slot is also provided at the front bottom edge of the Driver Display Unit to insert
the optional Driver Identification Card (see page 15). Driver Display Unit indicator
lights illuminate to indicate system power, system failure, absence of the Driver
Identification Card, SmartCruise system enabled, and multiple stages of warning
levels.
A light sensor in the face of the Driver Display Unit adjusts indicator brightness with
changes in ambient light. The Driver Display Unit also contains a small speaker that
provides audible alert tones. The alert tones are sounded when the vehicle is closing
on an object, or if an object is detected by the Side Sensor and the turn signal is
activated for a lane change. Additionally, the speaker provides informational tones
such as volume level, system failures, and the Driver Identification Card related
tones.
The Driver Display Unit mounts on top of, or is recessed in, the dashboard in an area
that is easily visible and accessible to the driver.
In certain applications there may not be a Driver Display Unit installed. The
information that is normally displayed on the Driver Display Unit may be included on
an OEM-installed integrated dashboard display. Consult the OEM literature for each
of these integrated systems for proper operation.

Component Description
Side Sensor (Optional)
The Side Sensor is also a radar device that senses objects from two (2) to ten (10)
feet (.6 - 3 m) from the side of the vehicle in a blind spot area on either side of the
vehicle. This information is provided to the Central Processing Unit for processing;
to activate the illumination of appropriate indicator lamps; and to sound appropriate
alarms. Side Sensor(s) are generally mounted on the right side of the vehicle, at or
near a blind spot area (see figure 2). The vehicle can be configured to have a Side
Sensor on each side, left or right, or with two sensors located on the same side.
Side Sensor Display (Optional)
The Side Sensor Display contains red and yellow indicator lights that denote whether
or not the Side Sensor is detecting an object. The yellow indicator light is illuminated
when there is no object within the Side Sensor detection zone. When the Side
Sensor detects an object, the red indicator light illuminates and the yellow indicator
light goes off. The red light also illuminates when the Side Sensor has failed. The
red and yellow lights may both illuminate simultaneously during system start-up, and
in certain heavy rain conditions. The Side Sensor may not be able to detect objects
in heavy rain. A light sensor in the Side Sensor display adjusts indicator brightness
with changes in ambient light.
The Side Sensor Display is generally mounted to the right side A-pillar (see figure 2)
on the inside of the vehicle, easily visible by the driver, and usually along the same
line-of-sight as the side mirror.

14
Driver ID Card (Optional)
Driver Identification Card
If the system configuration requires a Driver Identification Card, (see Figure 10), it
must be inserted into the slot provided on the front of the Driver Display Unit (see
Figure 8, page 13). After the system is powered on, insert the Card into the slot with
a smooth, steady, continuous motion. Allow approximately one (1) second to ensure
the bar code is read. A high-pitched confirmation tone will sound when the card
is correctly scanned. The card should be removed and stored in a safe place until
required again. If the bar code is not scanned correctly, the system will sound one
low-pitched tone.
If the Card is not installed into the slot in the Driver Display Unit, when required, two
events can occur: the green “ON” light will flash continuously; or the green “ON”
light will flash continuously accompanied by a matching audible tone. This is a
configurable option.

Initial Start-Up
Bendix™ VORAD® EVT-300™ System Start-Up
WARNING: Be sure the vehicle is not moving during the initial self-test
conducted at vehicle start-up. If the vehicle is in motion, the system
may not operate properly. No collision warning system alerts will be
given by the EVT-300 system until all lights are extinguished after the
self-test is complete.

16
The EVT-300 system powers up when turning the vehicle ignition key to the run
position. All Driver Display Unit and Side Sensor indicator lights will illuminate
and stay on until the self-test is complete.
If the green “ON” indicator is flashing, insert the Driver Identification Card (see
page 15) into the Driver Display Unit so the system can identify the driver of the
vehicle.
If the green “S/C” (Bendix™ SmartCruise®) light flashes eight (8) times after
the self-test is completed, an accident reconstruction event has been stored
in the system memory. The light will continue to flash eight (8) times during
every start-up until the event is cleared. Notify your management to assist you
with this procedure. If the event has been stored in error, the system software
should clear the system in 30 days.
If the “FAIL” indicator light (or headway control failure) illuminates and stays on
after the self-test or while driving, a component or system failure has occurred.
This may render the Bendix™ VORAD® system inoperable. If the Bendix™
SmartCruise® option is enabled and a failure occurs, the SmartCruise system
will no longer function (see page 25) until the fault has been corrected and the
ignition switch has been turned OFF and then back ON. Collision warning lights
and tones may still work correctly when the SmartCruise system failures occur
that are brought on by a component or system failure.
Typical System Tracking
Bendix™ VORAD® EVT-300™ System Vehicle Tracking
Straight Ahead Same Lane Tracking
The system’s same-line target discrimination capability eliminates detection of
nuisance objects in adjacent lanes.
Detected but not alerted
Critical Target
Detected but not alerted
Curved Same Line Tracking
While driving on curved roads, the same lane target discrimination is maintained
using the host vehicle turn rate information and vehicle azimuth (angle to object).
Due to limitations on the radar’s field of view, maximum range is limited in sharp
turns.
Detected but not alerted
Critical Target
17
Special Road Situations
Bendix™ VORAD® EVT-300™ System Road Situations
WARNING: The Bendix VORAD EVT-300 Collision Warning System
will not warn of all possible hazards. Do not assume it is “all clear” if
no warning signals are indicated. This system is intended solely as a
driver aid, and not to be relied upon to operate a vehicle. Use the
EVT-300 system in conjunction with rear view mirrors and other
instrumentation to maintain safe vehicle operation.
Certain road situations can affect the system’s ability to detect objects. Curves, dips,
and hills on the road in front of the vehicle can affect detection. The radar system
may sound a warning when it detects an object in front of the vehicle even though
the driver may be planning to turn away, or stop, prior to reaching the object. What
follows illustrates some special road situations that must be taken into account.
Detecting Objects While Vehicle is in a Turn
Audible alarms will not sound with oncoming traffic during very sharp right or left
hand turns of less than 750 feet (228 m) radius.
18
Special Road Situations
Detecting Objects Alongside an Approaching Curve
When approaching a curve, warnings may sound and indicators may illuminate due
to objects – such as a parked car – on the side of a curved portion of the road in
direct line with the radar beam, until the vehicle is actually starting into the turn.
Detected but not alerted
Critical Target
Detected but not alerted
Detecting Elevated Obstacles
Some unusual road elevation angles may cause the system to detect overhead
signs or overpasses.
19
Special Road Situations
Detecting Vehicles on the Other Side of a Hill
The system cannot detect vehicles over a hill. No audible alarm will sound until
objects are within the field of view of the radar antenna.
Approaching a Steep Hill
The system cannot detect objects above its beam. Generally, the alarm does not
sound from the beam hitting the road surface.
20
Special Road Situations
Side Sensor Coverage
Note that the optional Side Sensor(s) only detects object motion within its field of
view. This view includes the 2 to 10 feet (.6 - 3 m) next to the vehicle.
Note: Vehicles outside of the field of view will not be detected.
Side Sensor Range
The Side Sensor(s) range is set to detect vehicles in the adjacent lane two (2) to ten
(10) feet (.6 - 3 m) away.
Note: When a fixed object maintains a continuous presence along the right side of
the vehicle (e.g. guard rails, construction walls, tunnels, bridges, etc.), the
“red” light on the optional Side Sensor display may remain illuminated.
21
Bendix™ SmartCruise® System (Optional)
Bendix™ VORAD® EVT-300™ SmartCruise® System
(Optional)
The SmartCruise system is an optional enhancement to the Bendix VORAD
EVT-300 Collision Warning System. The SmartCruise system is activated whenever
the vehicle’s standard cruise control system is activated and the EVT-300 system is
powered on. When the SmartCruise system is active, the green “S/C” (SmartCruise)
light in the upper right corner of the Driver Display Unit will illuminate, or a headway
control indicator will be evident on an OEM-proprietary messaging center.
The “RANGE” control knob (see Figure 8, page 13) adjusts the Bendix SmartCruise
system’s “following intervals”. The SmartCruise system will either maintain the
selected following interval between the host vehicle and a vehicle ahead or, in the
case of no target vehicle, the set cruise control speed. The following interval takes
precedence over the set cruise control speed.
Listed below are descriptions of the most common situations encountered while
using the SmartCruise system.
•
Cruise Control is On and No Vehicle is Detected
If no vehicle is present in front of the vehicle (or if present and
beyond the range of the EVT-300 system), the vehicle will maintain
the speed selected by the cruise control.
•
Cruise Control is On and A Vehicle is Detected
The driver can adjust the SmartCruise system following interval from
2.25 to 3.25 seconds if enabled. See the table on next page for the
following interval (in seconds) versus the following interval in feet, at
various speeds.
WARNING: The Bendix SmartCruise system does not replace an
alert, trained driver. The SmartCruise system will not react to stationary
objects and cannot bring the vehicle to a complete stop. The driver still
needs to use good driving practices to avoid an accident.

Normal Operation
As the Bendix™ VORAD®-equipped vehicle approaches a target
vehicle in the same line, the VORAD-equipped vehicle will slow to the
speed of the other vehicle and maintain the set following distance
interval at their speed. The speed reduction may be accomplished
by the engine ECM (Engine Control Module) issuing a command to
reduce fuel, and engaging the engine retarder.
WARNING: If your vehicle speed and the forward vehicle speed are
drastically different, the driver may need to apply the service brakes
to maintain a safe distance. As with cruise control, the SmartCruise
system must be reset after brakes have been applied.
WARNING: If another vehicle in an adjacent lane cuts in front and
continues to the opposite lane, the SmartCruise system may not
respond.

Bendix™ SmartCruise® System (Optional)
Cut In and Out
If the speed of the forward vehicle is faster than that of your vehicle, your vehicle
will continue to maintain its speed. However, if the speed of the forward vehicle is
less than your vehicle’s speed, the engine ECM will issue a command to reduce
fuel and may also engage the engine retarder. Once the target vehicle moves out of
your lane, your vehicle will restore the cruise control speed, or resume the following
interval if another forward vehicle is in the lane. Again, the driver may need to apply
the service brake to maintain a safe distance. The driver may also depress the
acceleration pedal at any time to override the SmartCruise® system.
Cut In and Stay
If a forward vehicle in an adjacent lane cuts in front of your vehicle and remains
there, the system will respond by slowing your vehicle to restore the set following
distance interval to the forward vehicle. The engine ECM will reduce fuel and may
also engage the engine retarder to accomplish this. As stated above, the driver may
need to apply the brake to maintain a safe distance.
Vehicle Ahead Changes Lane
When maintaining a following interval to a forward vehicle, and that vehicle moves
into an adjacent lane, the system will respond. If there is no other vehicle ahead (or
within the range of the system), your vehicle will accelerate to the set cruise speed.
If there is another vehicle ahead, your vehicle will restore the following distance
interval to that vehicle. As stated above, the driver may need to apply the brake to
maintain a safe distance.
The Bendix SmartCruise System and AutoShift™ Transmissions
Under any situation that causes the system to slow the vehicle, and the engine RPM
reaches a preset minimum, the vehicle’s AutoShift transmission will automatically
downshift. Similarly, any situation that causes the vehicle to accelerate and a preset
maximum engine RPM is reached, the AutoShift will upshift.
The Bendix SmartCruise System and Manual Transmissions
Under any situation that causes the system to slow the vehicle, and the engine RPM
reaches a preset minimum, the engine ECM will disengage cruise control and the
driver may need to manually downshift the transmission. If this happens, the vehicle
cruise control will need to be re-engaged (Resume or Set) before the SmartCruise
system will resume operation.

Road Curves and the SmartCruise System
1.
Gentle Curves
The SmartCruise system will continue to maintain a set following
interval in a gentle curve as long as the turn is greater than 750 feet
(228 m) radius.
2.
Sharp Curves
When maintaining a set following interval, the system may lose track
of the forward vehicle. If this happens, your vehicle will maintain its
current speed. When the forward vehicle is again within the view of
the EVT-300 system, the SmartCruise system will restore the set
following interval. Refer to pages 17 through 21 for “Typical System
Tracking” and “Special Road Situations”.
Note: The previous paragraphs do not address all the possible driving situations that
the vehicle and driver may encounter while in SmartCruise.
SmartCruise System Failure
Cruise Control/SmartCruise System Fails to Operate
Due to the variety of engines available by OEM, the procedure to override this error
and return to normal cruise control must come from the engine manufacturer.
Note: The most widely used method among engine manufacturers is to toggle the
cruise control on/off switch two (2) times within 10 seconds starting from
the “ON” position. If this does not work, please contact your dealership or
maintenance personnel.
WARNING: The SmartCruise system is not a substitute for an alert,
trained driver. The driver is ultimately responsible for the safe operation
of the vehicle and the driver should fully understand the operating
characteristics of the SmartCruise system and take all necessary
actions to operate the vehicle in a safe manner.

In Case of an Accident
Accident Reconstruction Capability (Optional)
The Accident Recorder can store two segments of system data in the system’s
non-volatile memory. The first of the two segments may be stored by pushing
and holding the “RANGE” knob on the Driver Display Unit for approximately five
(5) seconds. Within six (6) seconds, the green “S/C” light will blink eight times,
confirming storage of the data (see Figure 11). Subsequent pushing of the
“RANGE” knob will cause the system to respond with a “FAIL” tone. After the first
segment is frozen, the second segment runs continuously recording system data
until the system is powered down.
The system’s Central Processing Unit must be returned to Bendix Commercial
Vehicle Systems to download and interpret the recorded data in the non-volatile
memory. This must be done before 30 days have elapsed, or the event will be
removed from the system memory. Before shipping the unit, contact Bendix at
1-800-247-2725. After confirmation, ship the Central Processor Unit to Bendix,

Maintenance/Diagnostic
Preventive Maintenance
The only maintenance required should be to keep the Antenna Assembly and Side
Sensor clean of heavy buildups of mud, dirt, ice, and other materials that could
reduce the range of the system. Antenna alignment should also be checked if any
occurrence may have caused it to be misaligned.
WARNING: The system will not sense objects if the sensor view is
obstructed. Therefore, do not place objects in front of the system
sensors. Remove heavy buildups of mud, dirt, ice, and other materials.
WARNING: Proper alignment is critical to correct operation of the
system (See BW2863 for Antenna Assembly Alignment procedure).
WARNING: Be sure the vehicle is not moving during the initial self-test
conducted at vehicle start-up. If the vehicle is in motion, the system
may not operate properly. No collision warning system alerts will be
given by the EVT-300 system until all lights are extinguished after the
self-test is complete.
Diagnostic Features
The system performs testing on a continuous basis. Every 15 seconds, the results of
these tests are evaluated by the Central Processing Unit to determine whether or not
to report a failure. If a failure occurs within the front radar system, the red “FAIL” light
on the Driver Display Unit will illuminate continuously as long as the failure is active,
and the associated failure code is stored in the Central Processing Unit memory until
maintenance personnel are able to check the system.
The Bendix™ VORAD® EVT-300 system can indicate active and inactive fault codes
stored in the Central Processing Unit memory when it is placed into its “Failure
Display Mode”. Inactive fault codes are faults which have occurred and have selfcorrected. Active faults are faults that are still present. These fault codes provide
the driver the ability to record the system fault during a trip and call either the
maintenance department or Bendix Commercial Vehicle Systems for assistance.
When placed into its “Failure Display Mode” (see “How to Activate Failure Display
Mode” on page 28), specific fault codes are indicated by a pattern of flashes blinked
out on the Driver Display Unit’s red “FAIL” light indicator.

Press in and hold the Driver Display Unit “VOLUME” knob for at least five
(5) seconds. If the knob is released before five (5) seconds has lapsed,
the system will turn off. After five (5) seconds the Driver Display Unit’s red
“FAIL” indicator light begins to blink out the failures. If there are no faults
found, the Driver Display Unit will flash a 41 code. At the conclusion of
flashing the fault codes, the system will flash a 41 code.
To read active fault codes, position the Driver Display Unit “RANGE”
knob to the left of center and only active codes will be sent to the “FAIL”
indicator light. Position the Driver Display Unit “RANGE” knob to the right
of center and inactive faults will flash the “FAIL” indicator light.
Each fault code consists of a two digit number. A pause (approximately 3/4
of a second in duration) separates the blinking of the first and second digit
of the fault code. Example: Fault code 22 is indicated by two (2) blinks,
a 3/4 second pause, and two (2) more blinks. In this case, the fault code
of 22, suspects a faulty “LT Turn Signal”. There is a pause of three (3)
seconds between each flash code fault. If there are no faults, a code 41
will be flashed.
Additional fault codes are blinked out at approximately eight (8) second
intervals. After all fault codes have been displayed, a code 41 will be
flashed.

No Fault or End of Fault Codes
Report any failures indicated by the Driver Display Unit or Side Sensor Display to
maintenance personnel for service. If the red “FAIL” indicator light comes on while
driving, turn the system off (if available), and do not use until it has been repaired.
Side Sensor failures will illuminate either the red or yellow lights on the Side Sensor
Display. The lights will remain illuminated as long as a failure is detected.
