battery KIA Optima Hybrid 2014 3.G Owner's Manual

H2
Kia Hybrid-Electric Vehicle (HEV)
uses a gasoline engine and an
electric motor for power. The elec-
tric motor is powered by a 270V
high voltage HEV battery.
The HEV computer decides when
to use the engine and when to use
electric motor, according to driv-
ing conditions. At times, both are
used simultaneously.
By turning off the engine under
certain conditions and using the
electric motor alone, the HEV sys-
tem saves fuel.
When the HEV battery reaches a
low state of charge, the engine will
cycle on and off to recharge the
battery. Charging also occurs
when decelerating by using
regenerative braking.Hybrid System Display
Many of the displays provide infor-
mation about the hybrid system,
such as the ECO Level and ECO
Score.
The ECO Level displays inform the
driver of the vehicle's fuel efficiency.
If the vehicle is driven economically,
the ECO Level rises. When the vehi-
cle is driven in EV mode, there is a
reduction in carbon dioxide (CO2)
emissions.
The Total ECO Score display indi-
cates the number of times the ECO
Level has reached its maximum.ECO Level display
When the vehicle is started, the ECO
Level display will indicate level 4. If
you drive economically, the ECO
Level will increase. However, if you
do not drive economically, the ECO
Level will decrease.

H3
State of charge
The state of charge (SOC) gauge
indicates the hybrid battery's charge
level. If the SOC is near Low (L)
level, the vehicle automatically oper-
ates the engine to charge the battery.
The gauge will rarely approach the
High (H) level. This is normal and is
not an indication of a malfunction.
However, if the service indicator and
MIL(Malfunction indicator lamp) turn
on when the State of Charge(SOC)
is near L, have your vehicle checked
by an authorized Kia dealer immedi-
ately.

WARNING
If the engine will not start after
cranking, press the Start/Stop
button to turn the system off.
This could result in the HEV bat-
tery becoming totally dis-
charged and is likely to be dam-
aged.

H4Kia hybrid system notifies the drivers
of energy flow in various operating
modes. Eleven Modes show drivers
the current operating condition.
Vehicle Stop
The mode means the vehicle at stop.
(No energy flow)
EV Propulsion
Motor power is used to move the
vehicle. (Battery

Regeneration
Hybrid battery is being charged by
regenerative braking.

Engine Brake
The vehicle is being slowed by
engine compression.

Power Reserve
Engine is both driving the vehicle
and charging the hybrid battery.

Engine Generation/Motor Drive
The vehicle is being slowed by
engine compression and regenera-
tive braking. The hybrid battery is

Engine Generation/Regeneration
The engine and regenerative braking
systems charge the hybrid battery
during deceleration.
(Engine & Wheel ➞Battery)
Engine Brake/Regeneration
The engine compression can be
used to slow the vehicle. The regen-
erative braking system can be used
to charge the hybrid battery.

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
Never touch orange or high volt-
age labeled components includ-
ing wires, cables, and connec-
tions. If the insulators or covers
are damaged or removed, severe
injury or death from electrocution
may occur.
WARNING
When touch the HPCU in the
engine compartment, especially
when replacing under hood
fuses or relays.
If you touch the HPCU, you may
get electrocuted resulting in
injury or death.

THE COMPONENTS OF HYBRID VEHICLE (CONT.)
WARNING
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
Do not use an after-market bat-
tery charger to charge the
Hybrid battery. Doing so may
result in death or serious injury.
WARNING - High Waters
• Avoid driving through high waters as this may result in
your vehicle becoming satu-
rated with water and could
compromise the high voltage
components.
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 components once
submerged in water could
result in severe burns or elec-
tric shock that could result in
death or serious injury.
WARNING
-
Carrying Liquids in Trunk
Do not load large amounts of
water in open containers in the
vehicle. If the water spills onto
the HEV battery, it may cause a
short and damage the battery.

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.
