WARNING
Do not disassemble or assemblethe package module. Doing so
may result in death or serious
injury.
If you disassemble or assemble hybrid system components
improperly, it may damage the
performance and reliability 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 examined by a doctor
as soon as possible.
WARNING
Never assemble or disassemble the
high voltage battery system.
If you assemble or disassemblethe high voltage battery system
arbitrarily, the durability and per-
formance of vehicle may be dam-
aged.
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). If not, severe burns and
electric shock may occur. For
your safety, do not touch the
cover of electronic components
and electronic cable. Do not
remove the cover of electronic
components and electronic cable
arbitrarily. In particular, Never
touch the high voltage battery
system when the hybrid system
operated. If not, it may result if
death or serious injury.
OYFH021003N
WARNING
Never use the package modules(high voltage battery, inverter,
converter) for any other purpose.
Do not use an after-market bat- tery charger to charge the high
voltage battery. Doing so may
result in death or serious injury.
Never put into a fire. Doing so may result in serious burns.
Never drill into, strike or other- wise damage the package mod-
ules. Doing so may result in seri-
ous injury or death.
CAUTION
When the vehicle is paint baked, do not pass 30 minutes in 158°F(70°C) or 20 minutes in 176°F(80°C) degree.
When you clean the engine com- partment, do not wash usingwater. Water may cause an elec-tric shock to occur and damageelectronic parts and components.

H11
The special features of hybrid
vehicle.
Hybrid vehicles sound different than
gasoline engine vehicles. When the
hybrid system operates, you may hear a
sound from the hybrid battery system
behind the rear seat. If you apply the
accelerator pedal rapidly, you may hear a
sound. when you apply the brake pedal,
you may hear a sound from the regener-
ative brake system. When the hybrid sys-
tem is turned off or on, you may hear a
sound in the engine compartment. If you
depress the brake pedal repeatedly
when the hybrid system is turned on, you
may hear a sound in the engine com-
partment. None of these sounds indicate
a problem. They are characteristics of
hybrid vehicles.
If any of following occur, it's not a unnor-
mal condition even if you may hear a
motor sound in the engine compartment.
- After turning off the hybrid system, thebrake pedal is released.
- When the hybrid system is turned off, the brake pedal is applied.
- When the driver door is opened. When the hybrid system is turned on, the
engine may run or not. In this situation,
you may feel a vibration. This does not
indicate a malfunction. If the "READY"
symbol is turned on, the hybrid system
starts. Even if the engine is off, you can
operate the vehicle.
WARNING
The hybrid system contains many
electronic components. High volt-
age components like cables and
other parts may emit electromag-
netic waves. Even if the electro-
magnetic cover blocks electromag-
netic emissions, electromagnetic
waves may have an effect on elec-
tronic appliances. If you park the
vehicle for a long time, the hybrid
system will discharge. You need to
drive the vehicle several times per
month. We recommend driving at
least 1 hour or 10 miles when you
drive the vehicle. If the hybrid bat-
tery is discharged and if it is impos-
sible to jump start the vehicle con-
tact your Hyundai dealer.
WARNING
When you start the hybrid system
in the "P" transmission position,
the "READY" symbol is illuminat-
ed in the cluster. The driver can
drive the vehicle even if the
engine is stopped.
When you leave the vehicle, you should turn off the hybrid system
or shift into the "P" position. If
you depress the accelerator
pedal by mistake and the vehicle
is not in the "P" position, the
vehicle will move abruptly. This
may result in serious injury or
death.
