Starting the Hybrid System
1.Carry the smart key into the vehicle.
2.Make sure the parking brake isfirmly applied.
3.Place the shift lever in the P(Park) position.
In N (neutral) position, you can not
start the vehicle.
4.Depress the brake pedal.
5.Press the engine start/stop button.
6.The engine should be started with- out pressing the accelerator. In
extremely cold weather or after the
vehicle has not been operated for
several days, let the engine warm up
without depressing the accelerator.
vehicle, if it is far away from you,
the engine may not start.
ton is in the ACC or ON position,
if any door is open, the system
checks for the smart key. If the
smart key is not in the vehicle, the
warning, "Key is not in vehicle"
will come on, and if all doors are
closed, the chime will also sound
for about 5 seconds. The indica-
tor will turn off while the vehicle is
moving. Keep the smart key in the
vehicle when using the ACC posi-
tion or if the vehicle engine is on. If the starting procedure is fol-
lowed, the " " symbol on the
instrument cluster will turn on. For
more details, Please check chap-
ter 4.

ECONOMICAL and SAFE
OPERATION of Hybrid system
Drive smoothly. Accelerate at amoderate rate and maintain a
steady cruising speed. Don't make
"jack-rabbit" starts. Don't race
between stoplights.
Avoid heavy traffic whenever pos-
sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear.
The regenerative brake generates energy when the vehicle deceler-
ates.
When the hybrid battery power is low, the hybrid system automatical-
ly recharges the hybrid battery.
When the engine runs in "N" posi- tion, the hybrid system cannot gen-
erate electricity. The hybrid battery
cannot recharge in "N" position.
Please refer to chapter 6.
✽ ✽ NOTICE
When the hybrid system is in ready
mode, the engine will automatically
start and stop as needed.
The " " symbol will illuminate in
the cluster when the system is oper-
ational.
CAUTION - Extended
cranking
Do not crank the engine for aprolonged period of time with-out the engine starting. Thiscould result in damage to theHEV battery and becomingtotally discharged.

The Hybrid battery uses high voltage
to operate the electric motor and
other components and other compo-
nents. High voltage is dangerous if
touched.
Your vehicle is equipped with orange
colored insulation and covers over
the high voltage components to pro-
tect people from electric shock. High
voltage warning labels are attached
to some system components as addi-
tional warnings. Have your vehicle
serviced by an authorized Kia dealer.
WARNING - High voltage
components
Never touch orange or high
voltage labeled components
including wires, cables, and
connections. If the insulators or
covers are damaged or
removed, severe injury or death
from electrocution 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.

✽
✽NOTICE - Prolonged parking
Prolonged parking might cause bat-
tery discharge and operation failure
due to natural discharge. Driving
the vehicle approximately once
every 2 months, more than 9 miles
(15 km) is recommended. The bat-
tery will be charged automatically
when driving the vehicle.
WARNING - Exposure to
High Voltage
High voltage in the hybrid bat- tery system is very dangerous
and can cause severe burns
and electric shock. This may
result in serious injury or death.
For your safety, never touch, replace, dismantle or remove
any portion of the hybrid bat-
tery system including compo-
nents, cables and connectors.
WARNING - Use of Water
or Liquids
If water or liquids come into
contact with the hybrid system
components, and you are also
in contact with the water, severe
injury or death due to electrocu-
tion may occur.
WARNING - Hot
Components
When the hybrid battery system
operates, the HEV battery system
can be hot. Heat burns may result
from touching even insulated
components of the HEV system.
CAUTION - Cleaning
Engine
When you clean the engine com- partment, do not wash usingwater. Water may cause electricarcing to occur and damage elec-tronic parts and components.

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.
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.

The HEV system may emit electro-
magnetic waves which can affect the
performance of electronic devices
appliances, such as laptop comput-
ers, 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 approximate-
ly once every 2 months, more than 9
miles (15 km) is recommended.
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.Virtual Engine Sound System
(VESS)
The Virtual Engine Sound System
generates engine sound for pedestri-
ans to hear vehicle sound because
there is limited sound while electric
motor power is used.
If the vehicle is moving at lowspeed, the VESS will operate.
When the gear is shifted to R (Reverse), an additional warning
sound will be heard.
WARNING - Turning off
HEV system
When you leave the vehicle, you
should turn off the hybrid sys-
tem. If you depress the acceler-
ator pedal by mistake and the
vehicle is not in the "P" posi-
tion, the vehicle will accelerate.
This may result in serious injury
or death.

High Voltage Battery Air Intake
The hybrid battery air intake is locat-
ed on bottom and side of the rear
seats. The air intake cools down the
hybrid battery. When the hybrid bat-
tery air intake is blocked, the hybrid
battery may be overheated. Do not
obstruct the air intake with any other
objects.
If An Accident Occurs
Avoid the engine compartment.
Avoid any orange or high voltagewires, cables, or components.
Assume that a high voltage compo- nent is exposed and move away from
the vehicle as promptly as possible.
Refer to Chapter 7 for towing infor- mation.WARNING - Air Intake
Blocking the air intake behind the rear seats may damage
the HEV battery.
Do not allow any water into the air intake even when
cleaning. If any water enters
the air intake, the Hybrid bat-
tery may cause an electric
shock which can cause seri-
ous injury or death due to
electrocution.

WARNING
-
Interference with electron-
ic medical devices
Electromagnetic waves that are
generated from the charger can
impact medical electric devices
such as an implantable cardiac
pacemaker. When using such
medical electric devices, ask
your medical professional and
the device manufacturer
whether charging your electric
vehicle will impact the operation
of the medical electric devices.
