SAFETY PRECAUTIONS FOR HYBRID SYSTEM
Hybrid Vehicle Components
High voltage battery system
„„HPCU (Hybrid Power Control Unit) *1
OCN7HQ010006
„„High voltage battery system *2
OAEQ046019
*1 : Located in the engine compartment
*2 : Located under the rear seats
WARNING
Never touch orange colored or high
voltage labeled components, including
wires, cables, and connections. When
the insulators 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 carries high voltage.
Touching the HPCU may result in
electrocution, 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,
serious injury or death may occur.
CAUTION
• Do not pile up any items in an area
behind the high voltage battery. In
a crash, the battery may become
unstable, or its performance may
degrade.
• Do not apply strong force nor pile
up any items above the luggage
compartment. Such an attempt
may distort the high voltage battery
case, causing a safety problem or
degrading the performance.
• Be careful when loading flammable
liquid in the luggage compartment.
It could cause operational and safety
degradation if the liquid leaks and
flows in the high voltage battery.

NOTICE
• When the vehicle is paint baked, do
not bake over 30 minutes in 158°F
(70°C) or 20 minutes in 176°F (80°C)
degree.
• Do not wash the engine
compartment, using water. Water
may cause an electric shock and
damage the electronic components.
WARNING
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 system
operates, the hybrid battery system
can be hot. Always be careful
because burns or electric shock may
be caused by high voltage.
• Do not spill liquid on the HPCU, HSG,
motor and fuses. If the hybrid system
components come in contact with
liquid, it may result in electric shock.
Service Interlock Connector
OCN7HQ010001
In case of emergency, cut the service
interlock connector cable to isolate the
high voltage of the battery.
WARNING
Never disconnect the service interlock
connector or cut the wire except in an
emergency situation.
Serious problems may occur, such as
the vehicle will not start.
Hybrid Battery Cooling Duct
OCN7HQ010002
The hybrid battery cooling duct is
located on the middle side of the rear
seats. The cooling duct cools down the
hybrid battery. When the hybrid battery
cooling duct is blocked, the hybrid
battery may be overheated.
Clean the cooling duct for the hybrid
battery with a dry cloth on a regular
basis.

NOTICE
Do not install any accessories on the
windows. The automatic reverse
feature may not operate.
Power window lock switch
OCN7050027
The driver can disable the power window
switches on the rear passenger doors by
pressing the power window lock switch.
When the power window lock switch is
pressed:
• The rear passenger control will not
be able to operate the rear passenger
power window
• Note that the front passenger control
is still able to operate the front
passenger window, and that the driver
master control can still operate all the
power windows.
NOTICE
• To prevent possible damage to the
power window system, do not open
or close two windows or more at the
same time. This will also ensure the
longevity of the fuse.
• Never try to operate the main
switch on the driver’s door and the
individual door window switch in
opposite directions at the same time.
If this is done, the window will stop
and cannot be opened or closed.
WARNING
• NEVER leave the keys in your vehicle
with unsupervised children, when
the engine is running.
• NEVER leave any child unattended in
the vehicle. Even very young children
may inadvertently cause the vehicle
to move, entangle themselve s in
the windows, or otherwise injure
themselves or others.
• Always double check to make
sure arms, hands, head and other
obstructions are safely out of the
way before closing a window.
• Do not allow children to play with the
power windows. Keep the driver’s
door power window lock switch in
the LOCK position (pressed). Serious
injury can result from unintentional
window operation by the child.
• Do not extend your head, arms or
body outside the windows while
driving.
