Introduction
INTRODUCTION
This manual describes the operating features and safety equipment of the Orion VII EPA10 Hybrid Vehicle. All
personnel involved in the operation of this vehicle should read this manual before providing any public service.
For additional information or assistance, refer to the contact information located at the back of this manual.

General
GENERAL
The Orion VII EPA10 hybrid vehicle incorporates specia lly des igned features that provi de transp orta tion to the mobili ty
impaired and physically challenged. It is the operator’s responsibility to assist each passenger in boarding, seating,
attaching and securing restraining belts, and to provide assistance when leaving the vehicle.
Special features of the vehicle fulfill passenger needs in the following areas:
• Kneeling and wheelchair ramp
features allow coach floor to
street level access for the
wheelchair bound individual.
• Restraining belts and
securement devices are
located at all wheelchair
positions.
• Pull cords and push buttons
alert the operator of the NEXT
STOP request, are easily
accessible.

HYBRID ELECTRIC VEHICLE (H.E.V.) SAFETY INFORMATION
Hybrid Electric Vehicle Propulsion System
Due to extremely high voltage
supplied by the energy storage
system (ESS), the propulsion
system contains a battery isolator
switch which allows the operator to
cut off propulsion system power in
special circumstances such as a
vehicle accident. This switch is
located in the curbside battery
compartment.
of Electrical System” on page 49.
See “Disconnection
High Voltage Hazards
Use extreme caution if any work
has to be performed on the
engine while it is running. High
voltage is present at the
generator terminals, traction
motor terminals, and all high
voltage cabling connecting the
generator and traction motor to
the Propulsion Control System
(PCS).
Use of the Battery Isolator
Switch is mandatory during
propulsion system maintenance.
If the vehicle was running just
prior to conducting
main99tenance, allow four
minutes for propulsion system
components to discharge
electricity before proceeding.
Even with the Battery Isolator
Switch in the OFF position, the
traction battery system remains
a severe shock hazard because
the battery modules themselves
are not disconnected by the use
of this switch. Always use
extreme caution when working
around the rooftop tub.
Although the operator would rarely
have access to any of the
propulsion system components,
he/she must be made aware of the
potential hazards.
Should a problem exist which
requires attention to the propulsion
system, the matter should
immediately be brought to the
attention of qualified service
personnel. For further information
on the HEV system, refer to BAE
Systems™ maintenance manual.

position and the brake pedal is
released.
This foot-operated treadle
valve, located on the
compartment floor to the
immediate right of the steering
wheel, applies the vehicle
service brakes.
13. Accelerator Pedal

20. Driver’s Door Control Push
Buttons
The rear and front door
controller push buttons allow
the operator to activate the
front and/or rear door s. Press
once to open and press again
to close the doors.
21. Tilt/Telescopic Steering
Column Lever
Stop the vehicle and apply the
parking brake before adjusting
the steering column. Failure to
do so could result in loss of
vehicle control, causing perso nal
injury and/or vehicle damage.
The steering column is
equipped with adjustment
features that accom modate the
size and height of most
operators. Tilt and height
features are adjusted using a
lever on the left hand side of
the steering column.
To adjust the tilt angle:
a. Pull back on the lever.

3. Diesel Emission Fluid (DEF)
Gauge
This gauge measures the
amount of DEF in the 10.6
gallon reservoir tank. Diesel
emission fluid is mixed with hot

“Air Brake System
Operation” on page 32.
5. Engine Coolant Temperature
Gauge
This gauge registers the engine
coolant temperature. The
gauge is designed to register a
temperature range from 100° 260°F (38° - 127°C). The
normal operating temperature
is between 180° - 200°F (82° 93°C). If the temperature
continues to rise above this
range, the excessive high
temperature will trigger an
audible alarm and il luminate the
CHECK ENGINE indicator on
the front instrument pa nel. If the
engine temperature continues
to rise above 212°F (100°C),
the engine control unit (ECU)
will commence shutdown
sequence.
See
