High Voltage Battery System
OAEPHQ016040L
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.

•Do not disassemble the high
voltage motor connector. The
high voltage motor connector
may contain residual high
voltage. Coming in contact
with high voltage may result
in death or serious injury.
•Your vehicle's hybrid system
should only be inspected or
repaired by an authorized
HYUNDAI dealer.
WARNING
•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 flam-
mable liquid in luggage com-
partment. It could cause oper-
ational and safety degrada-
tion if the liquid leaks and
flows in high voltage battery.
CAUTION
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 bat-
tery system, serious injury or
death may occur.
WARNING

H49
• When the vehicle is paint baked,
do not bake over 30 minutes in
70°C (158°F) or 20 minutes in
80°C (176°F) degree.
• Do not wash the engine compart-
ment, using water. Water may
cause an electric shock to and
damage the electronic.
NOTICE
•Never use the package mod-
ules (high voltage battery,
inverter and converter) for any
other purpose.
•Do not use an unauthorized
battery charger to charge the
high voltage battery. Doing so
may result in death or serious
injury.
•Never locate the high voltage
system near or in a fire.
•Never drill into or strike the
package module. Otherwise, it
may be damaged. An electric
shock may occur, resulting in
serious injury or death.
WARNING
•Do not disassemble or assem-
ble the high voltage battery
system. Doing so may result
in electric shock, causing
death or serious injury.
•If you disassemble or assem-
ble hybrid system compo-
nents improperly, it may dam-
age the performance and reli-
ability of your vehicle.
•If electrolyte comes in contact
with your body, clothes or
eyes, immediately flush with a
large quantity of fresh tap
water. Have your eyes exam-
ined by a doctor as soon as
possible.
WARNING
Never assemble or disassemble
the high voltage battery system.
•If you assemble or disassem-
ble the high voltage battery
system, the durability and per-
formance of the vehicle may be
damaged.
•When you want to check the
high voltage battery system,
have the vehicle checked and
inspected by an authorized
HYUNDAI dealer.
•Do not touch the high voltage
battery and high voltage cable
connected to motor (orange
color). Severe burns and elec-
tric shock may occur. For your
safety, do not touch the cover
of electronic components and
electronic cable. Do not remove
the cover of electronic compo-
nents and electronic cable. In
particular, never touch the high
voltage battery system when
the hybrid system in operation.
It may result in death or serious
injury.
WARNING

H50
Service Plug
Never touch the service plug.
Service plug is attached to high
voltage hybrid battery system.
Touching the service plug will
result in death or serious injury.
Service personnel should follow
procedure in service manual.

SAFETY PRECAUTIONS FOR HYBRID SYSTEM (CONT.)
(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 seri-
ous 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.

WARNING

H51
Hybrid Battery Cooling Duct
The hybrid battery cooling duct is
located on the left 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.Do not obstruct the cooling duct with
any other objects.
Information
Clean the cooling duct for the hybrid bat-
tery with a dry cloth on a regular basis.
i
(Continued)
•Do not put any objects into
the cooling duct of the hybrid
battery. Doing so may cause
loss of cooling duct volume to
the hybrid battery. When the
cooling duct is blocked with
any objects, immediately con-
tact your HYUNDAI dealer.
•Never place a container of liq-
uid on or near the cooling
duct. If the liquid spills, the
hybrid battery located in the
luggage compartment may be
damaged.
•Secure all loads in the lug-
gage compartment to prevent
them from being tossed about
before driving. When a sharp
or heavy load strike with a
strong impact or pierce the
interior luggage compartment
wall, the hybrid battery sys-
tem may be damaged, deterio-
rating its performance.
•Never clean the cooling duct
of the hybrid battery with a
wet cloth. If any water enters
in the cooling duct of the
hybrid battery, the hybrid bat-
tery may cause an electric
shock, resulting in a serious
damage, an injury or a death.
•The hybrid battery is com-
posed of lithium-ion polymer.
If the hybrid battery is improp-
erly handled, it is dangerous
to the environment. Also it
may cause electrical shock
and severe burns, resulting in
a serious injury or a death.
•Do not spill liquid over the
cooling duct of the hybrid bat-
tery. Doing so is very danger-
ous. It may cause electric
shock or serious injury.
•Do not cover the cooling duct
with objects.

If an Accident Occurs(Continued)
Using small amount of water
or fire extinguishers not
meant for electrical fires
could cause serious injury or
death from electrical shocks.
•Upon witnessing any sparks,
gases, flames, or fuel leakage
of your vehicle, immediately
call emergency services or
contact an authorized
HYUNDAI dealer. Also, advise
them that a hybrid vehicle is
involved.

H53
When the Hybrid Vehicle Shuts
Off
When the high voltage battery is dis-
charged, when the 12-volt battery is
discharged, or when the fuel tank is
empty, the hybrid system may not
operate while driving. When the
Hybrid system does not operate, do
the followings:
1.Gradually reduce the vehicle
speed. Pull over your vehicle off
the road in a safe area.
2. Locate the shift lever in P (Park).
3. Turn ON the hazard warning flashers.
4.Turn OFF the vehicle, and try to
start the hybrid system again,
while depressing the brake pedal
and turning on the ignition switch.5.When the hybrid system still does
not operate, refer to "If the 12 Volt
Battery Is Discharged" in chapter 6.
Before jump-starting the vehicle,
check the fuel level and the exact
procedure to jump start. For further
details, refer to "If the 12 Volt
Battery Is Discharged" in the chap-
ter 6. When the fuel level is low, do
not attempt to drive the vehicle only
with the battery power. The high
voltage battery may be discharged,
and the hybrid system will turn OFF.When a submersion in water
occurs:
When your vehicle is flooded in
water, a high-voltage battery
may cause shock or fires. Thus,
turn the hybrid system OFF, take
the key in your possession and
escape to a safe place. Never
attempt physical contact with
your flooded vehicle.
Immediately contact an author-
ized HYUNDAI dealer and advise
them that a hybrid vehicle is
involved.
