The Hybrid battery uses high-voltage
to operate the electric motor and
other components. High voltage is
dangerous if touched.
Your vehicle is equipped with orange
colored insulation which covers over
the high voltage components to pro-
tect people from electric shock.
High voltage warning labels are
attached to some system compo-
nents as additional warnings. Your
vehicle is recommended to be serv-
iced by an authorized Kia dealer.
WARNING - High voltage
components
Never touch orange or high-volt-
age labeled components includ-
ing wires, cables, and connec-
tors. If the insulators or covers
are damaged or removed, severe
injury or death from electrocu-
tion may occur.
WARNING- Touching HPCU
When replacing the fuses in the
engine compartment, never
touch the HPCU. The HPCU car-
ries high voltage. Touching the
HPCU could result in electrocu-
tion, serious injury, or death.

Safety plugSome Special Features of the
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 regenerative brake
system. When the hybrid system is
turned off or on, you may hear a
sound in the engine compartment. If
you depress the brake pedal repeat-
edly when the hybrid system is
turned on, you may hear a sound in
the engine compartment. None of
these sounds indicate a problem.
They are characteristics of hybrid
vehicles.
When the hybrid system is turned on,
the engine may run. This does not
indicate a malfunction. If the “ ”
symbol is on, the hybrid system is
operating. Even if the gasoline engine
is off, you can operate the vehicle.The HEV system may emit electromag-
netic waves which can affect the per-
formance of electronic devices appli-
ances, such as laptop computers,
which are not part of the vehicle design.
If you park the vehicle for a long time,
the hybrid system will discharge. You
need to drive the vehicle several times
per month to maintain a charge.
When you start the hybrid system in
the "P" transmission position, the
“ ” symbol is illuminated in the
cluster. The driver can drive the vehi-
cle even if the engine is stopped.
OJFHPQ018053
WARNING- Safety Plug
Never touch the safety plug.
Safety plug is attached to high
voltage hybrid battery system.
Touching safety plug will result
in death or serious injury.
Service personnel should follow
procedure in service manual.
WARNING- Turning off HEV system
When you leave the vehicle, you
should turn off the hybrid sys-
tem. If you depress the accelera-
tor pedal by mistake and the vehi-
cle is not in the "P" position, the
vehicle will accelerate. This may
result in serious injury or death.

Virtual Engine Sound System
(VESS)
The Virtual Engine Sound System
generates a simulated engine sound
for pedestrians to hear the vehicle
while at low speeds in EV mode.
High Voltage Battery Air Intake
Hybrid battery air intake
The hybrid battery air intake is locat-
ed at the bottom the rear seats.
The air intake cools down the hybrid
battery.
When the hybrid battery air intake is
blocked, the hybrid battery may over-
heat. Do not obstruct the air intake
with any other objects.
Plug-in Hybrid Vehicle
The high-voltage battery air intake is
located on the left side of the rear
seats. The air intake cools down the
high-voltage battery.
When the high-voltage battery air
intake is blocked, the high-voltage
battery may overheat and the vehicle
performance may become limited
and set a hybrid warning lamp. Do
not obstruct the air intake with any
other objects.OJFHQ015005
