Starting the Hybrid System
1.Carry the smart key into the vehi-cle.
2.Make sure the parking brake is firmly applied.
3.Place the shift lever in the P(Park) position.
In N (neutral) position, the engine
(hybrid system) will not start.
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 acceler-
ator.
• Even if the smart key is in thevehicle, it muse be within range of
the antenna before the engine
(hybrid system) will 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 "READY" symbol on
the instrument cluster will turn on.

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 excessive idling.
Obey the speed limit.
Monitor the Eco Guide Indicator.
Use Cruise control Whenever
Possible.
Use Auto Mode when setting the
Air Conditioning.
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 5.
✽ ✽ NOTICE
When the hybrid system is in
READY mode, the engine will auto-
matically start and stop as needed.
The "READY" symbol will illumi-
nate in the cluster when the system
is operational.

H10
The high voltage Hybrid battery is
used to operate the electric motor
and other components. 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
additional warnings. Your vehicle's
hybrid system should therefore only
be inspected or repaired by an
authorized Kia dealer.
WARNING- High voltagecomponents
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.

HPCU
HEV Battery
WARNING- Touching HPCU
When replacing fuses or relays
under the hood, do not touch
the HPCU in the engine com-
partment. Touching the HPUC
cause death or severe injury
from electrocution.
THE COMPONENTS OF HYBRID VEHICLE (CONT.)
CAUTION - HPCU Damage
Do not touch the HPCU when replacing fuses or relays in theengine compartment. Touchingthe HPCU can result in damageto the unit.

H11
WARNING - Battery
Electrolyte
As with all batteries, avoid fluid
contact with the Hybrid battery.
If the battery is damaged and if
electrolyte comes in contact
with your body, clothes or eyes,
immediately flush with a large
quantity of fresh water.

WARNING - After-market
Battery Charger
Do not use an after-market bat-
tery charger to charge the Hybrid
battery without confirming that it
meets all safety and effective-
ness specifications for this prod-
uct. An inadequate hybrid battery
may malfunction and result in
death or serious injury.
CAUTION - Immersing
Vehicle in High Water
Avoid driving into or otherwise allowing water to get into yourengine compartment as thismay result in your vehiclebecoming saturated with waterand could damage high voltagecomponents.
CAUTION - Carrying
Liquids in Trunk
Do not load large amounts of water in open containers in thevehicle. If the water spills ontothe HEV battery, it may cause ashort and damage the battery.
WARNING - High Waters
• Avoid driving through high waters as this may result in
your vehicle becoming saturat-
ed with water and could com-
promise the high voltage com-
ponents.
Do not touch the any of the high voltage components within
your vehicle if your vehicle has
been submerged in water equal
to half of the vehicle height.
Touching high voltage compo-
nents once submerged in water
could result in severe burns or
electric shock that could result
in death or serious injury.

H12
THE COMPONENTS OF HYBRID VEHICLE (CONT.)
CAUTION - Cleaning
Engine
When you clean the enginecompartment, do not washusing water. Water may causeelectric arcing to occur anddamage electronic parts andcomponents.
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 sys-
tem can be hot. Heat burns may
result from touching even insu-
lated components of the HEV
system.

H13
Service plug
This service plug (1) located in the
rear trunk as shown should always
be pulled out to disconnect and turn
off the hybrid system.
IMPORTANT: Wait 5 minutes after
this lever is disconnected to work
on the car. This ensures that all
remaining electrical charge in the
system is dissipated.
Some Special Characteristics
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 normal characteristics of
hybrid vehicles.
When the hybrid system is turned
on, the engine may or may not start
immediately. This does not indicate a
malfunction. If the "READY" symbol
is on, the hybrid system is operating.
Even if the gasoline engine is off, you
can operate the vehicle.
OTFH063020
WARNING - Safety plug
Never touch the safety plug. The
safety plug is attached to high
voltage hybrid battery system.
Touching safety plug can result
in death or serious injury.
Service personnel should follow
procedure in service manual.
WARNING - Interference
with electronic 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 elec-
tric devices, ask your medical
professional and the device
manufacturer whether charging
your electric vehicle will impact
the operation of the medical
electric devices.

H14The HEV system may emit electro-
magnetic waves which can affect the
performance of electronic devices,
such as laptop computers.
If you park the vehicle for a long time,
the hybrid system will discharge. The
vehicle should be driven at least
once per month to maintain a
charge.
When you start the hybrid system in
the "P" transmission position, the
"READY" 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 an engine sound for
pedestrians to hear the vehicle while
at low speeds in EV mode.
WARNING - Turning off
HEV system
When you leave the vehicle, turn
off the hybrid system. If you
leave the hybrid system on, you
or another vehicle occupant
could depress the accelerator
pedal and, if it is in a position
other than Park, the vehicle will
begin accelerating. This may
result in an accident causing
serious injury or death.
