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 Eaton 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 at vehicle’s start-up. Otherwise, the system may not
operate properly.

Overview
VORAD EVT-300 Overview
The Eaton 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, respectivily.
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 also has the ability to operate in a mode called “SmartCruise”.
SmartCruise 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
EVT-300 Components
The Eaton 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.

Central
Processing Unit
Figure 1
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 will simultaneously
monitor 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 EVT300 Collision Warning System. The CPU and Antenna Assembly are programmable though a slot located in the opposite end from the cable connection on
the CPU (system parameters can be set with a Prolink Diagnostic Tool or ServiceRanger). 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 SmartCruise. 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 come on to indicate system power, system failure, absence of the Driver
Identification Card, SmartCruise 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 your OEM
literature for 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, lighting of appropriate indicator lamps, and sounding of
appropriate alarms. Side sensors 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 have two sensors
located on the same side.
Side Sensor Display (Optional)
The Side Sensor Display contains red and yellow indicator lights that indicate
whether or not the Side Sensor is detecting an object. The yellow indicator
light is on 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 lights goes off. The red light also illuminates when the
Side Sensor has failed. The red and yellow lights may illuminate together during system start-up, and in certain heavy rain conditions. The Side Sensor
may not be able to detect 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, easy visible by the driver, and usually
along the same line of sight as the side mirror.

When rotated from minimum to maximum*, and
not in SmartCruise*, this control knob provides
range adjustment of the first alert (3 to 2 seconds) and the second alert (2 to 1.75 seconds).
Function may be configured to prevent range
adjustment control* (See Figure 5). When
SmartCruise is selected, rotation of the knob,
from maximum to minimum, will change the following interval from 3.25 to 2.25 seconds. Accident Reconstruction is initiated by pushing and
holding this knob for 5 seconds thereby freezing
the most recent event data in half of the allocated memory. (See “In Case of an Accident”
page 26) (See Figure 5)
Red, System Failure
Illuminates when a problem has been detected
in the forward looking radar system. A pattern of
flashes blink out the faults that are stored in
memory when activated by holding in the volume control knob for five seconds (See “Diagnostic Features”, page 27). (See Figure 5)
Green, SmartCruise*/
Accident Reconstruction*

vehicle cruise control has been engaged. If Accident Reconstruction* has been initiated to store
information, it will flash 8 times. After system
power-up and power-on LED test is completed
and if Accident Reconstruction information was
previously stored, the display will flash 8 times.
(See Figure 5)
Light Sensor
Photo sensor senses ambient lighting and
adjusts intensity of the indicator lights accordingly, i.e., increases brightness of indicator
lights in daytime and decreases brightness of
indicator lights during nighttime. (See Figure 5)

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 reading of the bar code. A high-pitched confirmation tone will sound when the card is correctly scanned. The card should be
removed and stored is a safe place until required again. If the bar code is not
scanned correctly, one low-pitched tone will be heard.
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
EVT-300 Start-Up
WARNING: Be sure the vehicle is not moving during the initial
self-test at vehicle’s start-up. Otherwise, the system may not
operate properly. No Collision Warning System alerts will be
given by the EVT-300 until all lights are extinguished after the
self-test is complete.
1.
2.
3.
4.
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” (SmartCruise) light flashes eight (8) times after the
self-test is completed, an Accident Reconstruction event has been
stored in memory. The light will continue to flash 8 times during
every start-up until the event is cleared. Notify management to assist
you with this procedure. If the event has been stored mistakenly, the
system software should clear the system in 30 days.
If the “FAIL” indicator light (or headway control failure) comes on
and stays on after the self-test or while driving, a component or system failure has occurred. This may render the VORAD system inoperable. If the SmartCruise option is enabled and a failure occurs,
SmartCruise 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 SmartCruise failures occur that are brought on by a component or system failure.

Critical Target
Detected but not alerted
Curved Same Lane Tracking
While driving on curved roads, the same lane target discrimination is maintained using host vehicle turn rate information and vehicle azimuth. Due to
limitations on the radar’s field of view, maximum range is limited in sharp

17
Special Road Situations
EVT-300 Road Situations
WARNING: The 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 in conjunction with rear view mirrors and other instrumentation to maintain safe operation of the vehicle.
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. The following examples illustrate 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 Other Side of a Hill
The system cannot detect vehicles over a hill. No 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 (i.e. guard rails, construction walls, tunnels, bridges,
etc.), the “Red” light on the optional Side Sensor Display may stay on.
21
SmartCruise (Optional)
EVT-300 SmartCruise (Optional)
SmartCruise is an optional enhancement to the Eaton VORAD EVT-300 CWS
system. SmartCruise is activated whenever the vehicle’s standard cruise control system is activated and the EVT-300 is powered on. When SmartCruise 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 SmartCruise
“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 SmartCruise.
•
Cruise On and No Vehicle 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 On and Vehicle Detected
The driver can adjust the SmartCruise following interval from
2.25 to 3.25 seconds if enabled. See table on next page for following interval in seconds versus following interval in feet, at
various speeds.
WARNING: SmartCruise does not replace an alert, trained driver.
SmartCruise 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 VORAD-equipped vehicle approaches a target vehicle in
the same lane, the VORAD-equipped vehicle will slow to the
speed of the other vehicle and maintain the set following 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 the host vehicle speed and the target vehicle speed
are drastically different, the driver may need to apply the service
brakes to maintain a safe distance. As with cruise control, SmartCruise 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, SmartCruise may not respond.
23
SmartCruise (Optional)
Cut In and Out
If the speed of the target vehicle is faster than that of the host vehicle, the host
will continue to maintain its speed. However, if the speed of the target vehicle
is less than the host’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 the hosts lane, the host will restore the cruise control speed or resume
the following interval if another target 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 SmartCruise.
Cut in and Stay
If a target vehicle in an adjacent lane cuts in front of the host vehicle and
remains there, the system will respond by slowing the host to restore the set
following interval to the target vehicle. The engine ECM will reduce fuel and
may also engage the engine retarder to accomplish this. Again, the driver may
need to apply the brake to maintain a safe distance.
Vehicle Ahead Changes Lane
When maintaining a following interval to a target vehicle in front, 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), the host will accelerate to the set cruise speed. If there is another vehicle ahead, the host vehicle
will restore the following interval to that vehicle. Again, the driver may need to
apply the brake to maintain a safe distance.
SmartCruise and AutoShift™ Transmissions
Under any situation that causes the system to slow the vehicle, and the engine
RPM reaches a preset minimum, the AutoShift will automatically downshift.
Similarly, any situation that causes the vehicle to accelerate and a preset maximum engine RPM is reached, the AutoShift will upshift.
SmartCruise 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 SmartCruise will be operational again.

Road Curves and SmartCruise
1.
Gentle Curves
SmartCruise 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 target vehicle in front. If this happens, the host vehicle will maintain its current speed. When the target vehicle in
front is again within the view of the EVT-300, SmartCruise 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 Failure
Cruise Control/SmartCruise Fails to Operate
Due to various engine OEM’s, 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 2 times within 10 seconds starting from
the “ON” position. If this does not work, please contact your dealership
or maintenance personnel.
WARNING: SmartCruise 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 SmartCruise 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 Eaton Corporation
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 the Eaton Corporation at
1-800-826-HELP (4357). After confirmation, ship the Central Processor Unit
to Eaton Corporation, Attn: Accident Reconstruction Specialist, 13100 E.
Michigan Ave., Galesburg, MI 49053.

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 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 VOSM-0030 for Antenna Assembly Alignment procedure).
WARNING: Be sure the vehicle is not moving during the initial
self-test at vehicle’s start-up. Otherwise, the system may not
operate properly.
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 EVT-300 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 self-corrected.
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 Eaton Corporation 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.
It there are no faults, a code 41 will be flashed.
Additional fault codes are blinked out at approximately 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.
