2017 KIA OPTIMA PLUG-IN HYBRID Owners Manual

ENERGY FLOW HYBRID/PLUG-IN HYBRID VEHICLE
Kia 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.
(There is no energy flow.)
EV propulsion
Electric power is used to move the ve‐
hicle. (Battery Wheel)
Power assist
Electric and Engine power are used to
move the vehicle. (Battery & Engine
Wheel)

Engine generation/motor drive
The vehicle is being slowed by engine
compression and regenerative braking. The hybrid battery is being charged by
regenerative braking. (Engine

STARTING THE HYBRID/PLUG-IN HYBRID VEHICLE (SMART KEY)
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, you cannot
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 ex‐
tremely 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 the ve‐ hicle, if it is far away from you, the engine may not start. • When the engine start/stop but‐
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 vehi‐
cle" will come on, and if all doors
are closed, the chime will also
sound for about 5 seconds. The
indicator will turn off while the
vehicle is moving. Keep the smart
key in the vehicle when using the
ACC position or if the vehicle en‐
gine is on.
If the starting procedure is followed,the "READY" symbol on the instrumentcluster will turn on. For more details,please refer to L

NOTICE
When the hybrid system is in READY
mode, the engine will automatically
start and stop as needed. The
"READY" symbol will illuminate in the
cluster when the system is opera‐
tional.

COMPONENTS OF THE HYBRID/PLUG-IN HYBRID VEHICLE
0+')12-
1. Engine: 2.0L
2. Motor: 35 kW
3. Transmission: 6AT
4. Hybrid starter generator (HSG)
5. HPCU (Hybrid Power Control Unit)
6. High-voltage battery system
7. Regenerative brake system
8. Virtual Engine Sound System(VESS)
❈ The actual shape may differ from
the illustration.
The Hybrid battery uses high voltage 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 protect
people from electric shock. High voltage
warning labels are attached to some system components as additional
warnings. Your vehicle is recommended
to be serviced by an authorized Kia dealer.

WARNING
Never touch orange or high voltagelabeled components including wires,cables, and connections. If the insu‐lators or covers are damaged or re‐moved, severe injury or death fromelectrocution may occur.
WARNING
When replacing the fuses in the en‐gine compartment, never touch theHPCU. The HPCU carries high volt‐age. Touching the HPCU could resultin electrocution, serious injury, ordeath.
CAUTION
•Do not pile up any items in an areabehind the high voltage battery. Ina crash, the battery may becomeunstable, or its performance maydegrade.
(Continued)
(Continued)
•Do not apply strong force nor pileup any items above the trunk.Such an attempt may distort thehigh voltage battery case, causinga safety problem or degrading theperformance.
•Be careful when loading inflamma‐ble liquid in trunk. It could causeoperational and safety degrada‐tion if the liquid leaks and flows inhigh voltage battery.
