2013 KIA Optima Hybrid engine

H9
The Hybrid battery uses high voltage top
operate the electric motor and other
components and other components. High
voltage is dangerous if touched.
Your vehicle is equipped with orange col-
ored insulation and covers over the high
voltage components to protect people
from electric shock. High voltage warning
labels are attached to some system com-
ponents as additional warnings. Your
vehicle's hybrid system should therefore
only be inspected or repaired by an
authorized Kia dealer.
WARNING
Never touch orange or high voltage
labeled components including wires,
cables, and connections. If the insu-
lators or covers are damaged or
removed, severe injury or death from
electrocution may occur.
WARNING
When you replace the fuses, in the
engine compartment, never touch
the HPCU.
If you touch the HPCU, you may get
electrocuted resulting in injury or
death.

CAUTION - Cleaning
Engine
When you clean the engine com-partment, do not wash using water.Water may cause electric arcing tooccur and damage electronic partsand components.
WARNING -
Exposure to High Voltage
High voltage in the hybrid battery system is very dangerous and
can cause severe burns and elec-
tric shock. This may result in seri-
ous injury or death.
For your safety, never touch, replace, dismantle or remove any
portion of the hybrid battery sys-
tem including components,
cables and connectors.
WARNING - Use of Water
or Liquids
If water or liquids come into con-
tact with the hybrid system compo-
nents, and you are also in contact
with the water, severe injury or
death due to electrocution 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 com-
ponents of the HEV system.

H12
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. It is to be assured all remaining
charge in the system dissipated.
Some 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 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 vehi-
cles.
When the hybrid system is turned on, the
engine may run. 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 oper-
ate 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.

THE COMPONENTS OF HYBRID VEHICLE (CONT.)

H13
When you start the hybrid system in the
"P" transmission position, the "READY"
symbol is illuminated in the cluster. The
driver can drive the vehicle even if the
engine is stopped.
Virtual Engine Sound
System(VESS)
The Virtual Engine Sound System gener-
ates engine sound for pedestrians to
hear vehicle sound because there is no
sound while motor power is used.The hybrid battery air intake is located
behind the rear seats.The hybrid battery
air intake is used to cool the hybrid bat-
tery. If the hybrid battery air intake is
blocked, the hybrid battery may overheat.
Do not cover the air intake with objects.
WARNING
When you leave the vehicle, you
should turn off the hybrid system. If
you depress the accelerator pedal
by mistake and the vehicle is not in
the "P" position, the vehicle will
accelerate. This may result in seri-
ous injury or death.
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 battery may cause an
electric shock which can cause
serious injury or death due to
electrocution.

H14
If An Accident Occurs
Avoid the engine compartment.
Avoid any orange or high voltagewires, cables, or components.
Assume that a high voltage component is exposed and move away from the
vehicle as promptly as possible.
Refer to Chapter 6 for towing informa- tion or call Kia Roadside Assistance.
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 vehi-
cle 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 tostart the Hybrid system by applying the
brake pedal and pushing the start but-
ton.
3. If the Hybrid system will not operate, refer to "EMERGENCY STARTING" in
chapter 6. Before you try to jump start the vehicle,
confirm the fuel level. If the fuel level is
low add more fuel before attempting as
emergancy start.
THE COMPONENTS OF HYBRID VEHICLE (CONT.)
WARNING - Accident
Vehicle
Never touch electric wires or cable.
If exposed electric wires or cables
are visible inside or outside of your
vehicle, an electric shock may
occur.
WARNING - PUTTING OUT
FIRE
Never use water to put out a fire in
your vehicle. If a fire occurs, evalu-
ate the car immediately and contact
the fire department
