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 compart- ment, using water. Water may
cause an electric shock and may
damage electronic components.
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 place 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
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.
(Continued)
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.

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.
Safety Plug High Voltage Battery Cooling
Duct
The high-voltage battery cooling duct
is located on the left side of the rear
seats.
i
Never touch the safety plug. The
safety plug is attached to high
voltage hybrid battery system.
Touching the safety plug will
result in death or serious injury.
Service personnel should follow
procedures in service manual.

(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 compone nts, it
may result in electric shock.

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 vehiclespeed. 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 flash- ers.
4. Turn OFF the vehicle, and try to start the hybrid system again,
while depressing the brake pedal
and turning on the Engine
Start/Stop button. 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 fur-
ther details, refer to ''If the 12 Volt
Battery Is Discharged'' in the
chapter 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.
