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.
High Voltage Hazards
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.
DANGER
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).
DANGER
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.
DANGER
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.
