2015 KIA OPTIMA HYBRID Owners Manual

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.

CAUTION- Extendedcranking
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.

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
➞Wheel)
Power Assist
Electric and Engine power are used
to move the vehicle.
(Battery & Engine ➞ Wheel)
Engine Only Propulsion
Engine power is used to move the
vehicle. (Engine ➞Wheel)
Engine Generation
Vehicle is stopped with the Engine
charging the hybrid battery.

Regeneration
Hybrid battery is being charged by
regenerative braking.
(Wheel ➞Battery)
Engine Brake
The vehicle is being slowed by
engine compression.

Power Reserve
Engine is both driving the vehicle
and charging the hybrid battery.
(Engine ➞ Wheel & Battery)
Engine Generation/Motor Drive
The vehicle is being slowed by
engine compression and regenera-
tive braking. The hybrid battery is
being charged by regenerative brak-
ing.

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.

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.
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 and, even
without injury, can result in
damage to the HPCU.
