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.

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.

H41
If a vehicle accident occurs:
1.Stop the vehicle and shift the trans-mission into "P" position.
And then depress the parking
brake.
2.Turn off the Hybrid system by pushing the Engine Start/Stop
Button.
3.Evacuate to the safety place.
4.Call emergency services for help and let them know the vehicle is a
Hybrid vehicle. If an immersion in water occurs:
If your vehicle was flooded and has
soaked carpeting or water on the
flooring, you should not try to start
the Hybrid system. Have the car
towed to an authorized Kia dealer.When the hybrid vehicle shuts
off
When the high voltage battery or 12-
volt battery discharges, or fuel tank is
empty, the hybrid system may not
operate.
If the Hybrid system stops operating
while the vehicle is moving, reduce
the vehicle speed gradually. Pull
your vehicle off the road in a safe
area, and shift the transmission in to
Park (P) position and;
1. Turn on the hazard warning flashers.
2. Set the start button at OFF, and try
to start the Hybrid system by
applying the brake pedal and
pushing the start button.
3. If the Hybrid system will not oper- ate, refer to "EMERGENCY
STARTING" in chapter 7.
Before you try to jump start the vehi-
cle, confirm the fuel level. If the fuel
level is low add more fuel before
attempting as emergency start.
WARNING
If a submersion in water occurs:
If your vehicle was flooded and
has soaked carpeting or water
on the flooring, you should not
try to start the Hybrid system.
Never touch the high voltage
cables, connectors and pack-
age modules, because an elec-
trical shock may occur causing
injury or death. High Voltage
cables are orange in color.
We recommend that the car
towed to an authorized Kia dealer.
