Important Safety Information
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.
The Bendix®Intellipark®Electronic Parking Brake (EPB) system is a driver
assistance, not driver replacement, technology. Safe driving practices,
habits, and driver training are critical for safety on the road.
The driver should always manually set the parking brakes, and not rely on
the Intellipark EPB system to do so. Data captured through the Intellipark
EPB system will show any abuse or misuse of the system.

Introduction
This Operator’s Manual provides an overview of the Bendix®Intellipark®Electronic
Parking Brake (EPB) system Dash Electronic Control Unit (DECU) for buses/non-towing
vehicles. The manual explains the safe practices, functions, features, and alerts of
the system. Vehicles equipped with the Intellipark EPB system include electronic
switches (DECU) instead of pneumatic push/pull parking brake knobs.
Read this manual thoroughly before operating the system. Be familiar with the
controls, system alerts, and what to expect when the system is in operation. Keep this
manual in the vehicle as a reference for the system, its operation, and its performance
characteristics.

Included with the Bendix®Intellipark®EPB System
NOTE: Look for this warning label on
the visor. If this label is present, the
vehicle is equipped with the Intellipark
EPB system.
Pneumatic Push/Pull Knobs
Replaced by the Bendix®Intellipark®DECU (Switch)
This vehicle is equipped with a Bendix®Intellipark™ Electronic
Park Brake (EPB) system. Vehicle operators and maintenance
personnel must observe the LEDs present on the yellow
switches to determine the status of the Intellipark system.
Consult the Intellipark Owner’s Reference if all LEDs do not
illuminate immediately after the system powers ON, or if any
of the LEDs are blinking.

LEDs on the Dash Electronic Control Unit (DECU)
Illuminated LEDs on the parking brake switch indicate that the brakes are set.
Vehicle Startup
During vehicle startup, the LEDs located
on the DECU will illuminate for three (3)
seconds, turn o for two (2) seconds, then
indicate the parking brake status.

Driver Assistance Features
Rollaway Mitigation
The rollaway mitigation feature is intended to mitigate possible rollaway accidents
by automatically setting the parking brakes when the Bendix®Intellipark®Electronic
Parking Brake (EPB) system detects that the driver does not have control over the
vehicle and it is not parked.
The system will determine the driver does not have control when the vehicle speed is
stationary, the accelerator pedal not pressed, and the foot brake is not being applied.
In that scenario, the rollaway mitigation feature can engage after a few seconds (up
to 30 seconds) and automatically park the vehicle.
Smart Unpark™
At vehicle startup, once the brake pedal is depressed and the ignition power is on,
the driver can unpark the vehicle by pushing the parking brake switch. NOTE: The
vehicle will not unpark if the door is open. For electric vehicles, the vehicle will not
unpark if the charging cable is plugged in.
Rollaway Mitigation Acknowledgement
If the rollaway mitigation feature is
activated, both LEDs will continuously
blink. The LEDs will continue to blink until
the driver pulls the parking brake switch.
Releasing the parking brakes will not be
possible until the driver pulls the parking
brake switch.
Exhaust/Park-at-Speed
In an emergency situation, the Intellipark EPB system can help the driver achieve a
stop when service brakes are not available. Pull the parking brake switch until the
spring brakes have been applied. Once an Exhaust/Park-at-Speed event has been
initiated, if the driver stops pulling the parking brake switch at speed, the spring
brakes will release.

System Faults
WARNING: Blinking LEDs could indicate there is a problem or fault with
the system. Service the vehicle as soon as possible. In some instances,
parking brakes may be unavailable and the vehicle should NOT be driven.
WARNING: Non-blinking, illuminated LEDs
could be indicative of a fault. If one LED,
either the left or right, is fully lit and not
blinking, the system is faulted. The vehicle
should NOT be driven.

7
Parking with a Fault
Stop on a level surface. Shut o the engine and open the driver-side window to hear
air exhaust from the parking brakes. Perform the following steps:
1. Attempt to park the vehicle by pulling the parking brake switch. Listen for the
exhaust of air.
2. If the vehicle did not park, key o the vehicle and “fan down” the air reservoirs
by repeatedly depressing the service brake pedal to automatically apply the
spring brakes.
3. Chock the wheels.
4. Turn o the battery power to the vehicle.
Starting After a Fault
1. Ensure the reservoirs are depleted of air.
2. Once the reservoirs are depleted of air, remove the wheel chocks prior to starting
the engine.
3. Start the engine and stay in the driver’s seat as the air brake system builds air,
lling the reservoirs.
4. Keep the brake pedal depressed to hold the vehicle stationary in case the spring
brakes unintentionally release air.
5. Once the system air is at a normal operating range, the vehicle can be unparked
and driven.
