High Voltage Battery System
OLFHQ014002K
OLFHQ014009L
■ HPCU (Hybrid Power Control Unit)
■ High Voltage Battery System
Never touch orange colored or
high voltage labeled compo-
nents, including wires, cables,
and connections. When the insu-
lators or covers are damaged or
removed, severe injury or death
from electrocution may occur.
WARNING
While replacing the fuses in the
engine compartment, never
touch the HPCU. The HPCU car-
ries high voltage. Touching the
HPCU may result in electrocu-
tion, serious injury, or death.
WARNING
In the hybrid system, the hybrid
battery uses high voltage to
operate the motor and other
components. This high voltage
hybrid battery system can be
very dangerous. Never touch the
hybrid system. When you touch
the hybrid battery system, seri-
ous injury or death may occur.
WARNING

H45
Information
Gradual capacity reduction of the
high voltage battery.
The high voltage Battery capacity
gradually reduces with time and use.
This is natural characteristic of the
high voltage batteries. The extent at
which capacity is reduced changes
drastically depending on the environ-
ment(ambient temperature, etc.) and
usage conditions such as how the vehi-
cle is driven and how the high voltage
battery is charged. Reduction of the
high voltage battery capacity is not
covered under warranty.
i(Continued)
Do not drop water or liquid on
to HPCU, HSG, motor and
fuses. The hybrid system com-
ponents are covered. If you
drop water or liquid on to
hybrid system components, it
may result in electric shock.This hybrid vehicle uses the
hybrid battery system inverter
and converter to generate high
voltage. High voltage in the hybrid
battery system is very dangerous
and may cause severe burns and
electric shock. This may result in
serious injury or death.
For your safety, never touch,
replace, disassemble or remove
the hybrid battery system
including components, cables
and connectors. Severe burns
or electric shock may result in
serious injury or death when
you fail to follow this warning.
When the hybrid battery sys-
tem operates, the hybrid bat-
tery system can be hot. Always
be careful because burns or
electric shock may be caused
by high voltage.
