KIA OPTIMA PLUG-IN HYBRID 2017 User Guide

HEV (HYBRID ELECTRIC VEHICLE) SYSTEM
The Kia Hybrid Electric Vehicle (HEV) uses both the gasoline engine and the electric motor for power. The electric motor is run by a 270V high-voltage HEV battery.
Depending on the driving conditions, the HEV computer selectively operates between the engine and the electric motor or
even both at the same time.
Fuel efficiency increases when the engine is at idle, or when the vehicle is driven by the electric motor with the HEV battery.
The HEV battery charge must be maintained for the times when the engine acts as a generator, such as when stopped at idle.
Charging also occurs when decelerating or by regenerative braking.

PHEV (PLUG-IN ELECTRIC VEHICLE) SYSTEM
The Kia Plug-in Hybrid Electric Vehicle (PHEV) shares the characteristics of both a conventional hybrid electric vehicle and an
all-electric vehicle.
When used as a conventional hybrid electric vehicle, the HEV computer selectively operates between the engine and the elec‐ tric motor or even both at the same time.
When it is operating in the electric vehicle mode, the vehicle is driven only using the electric motor over a certain distance until
the hybrid battery becomes low. The driving distance in EV mode depends on customer driving style and road conditions. Ag‐ gressive driving maneuvers may at times temporarily enable the engine to operate for maximum power.
The hybrid battery can be fully charged by connecting a plug to an external electric power source.

• You can set reserved charging using the AVN.
Refer to the AVN for detailed infor‐mation about setting reserved charg‐
ing.
• Scheduled charging can only be done when using a normal charger or the
portable charging cable (ICCB: In-Ca‐
ble Control Box).

• When scheduled charging is set and the normal charger or the portable
charging cable (ICCB: In-Cable Control Box) is connected for charging, the
indicator lamp blinks (for 3 minutes)
to indicate that scheduled charging is
set. • When scheduled charging is set,
charging is not initiated immediatelywhen the normal charger or portable
charging cable (ICCB: In-Cable Control
Box) is connected. When immediate
charging is required, use the AVN to
deactivate the scheduled charge set‐ ting.

(Continued)
Do not connect the charging cableconnector plug to the vehicle if thereis water or dust on the charging in‐let. Connecting while there is wateror dust on the charging cable con‐nector and plug may cause a fire orelectric shock. There may be a riskof fire and injury when using oldworn out public electrical outlets.
WARNING
nInterference with electronicmedical devices
When using medical electric devicessuch as an implantable cardiac pace‐maker, make sure to ask the medicalteam and manufacturer whethercharging your electric vehicle will im‐pact the operation of the medicaldevices. In some instances, electro‐magnetic waves that are generatedfrom the charger can seriously im‐pact medical electric devices such asan implantable cardiac pacemaker.
WARNING
nTouching the charging connec‐tor
Do not touch the charging connector,charging plug, and the charging inletwhen connecting the cable to thecharger and the charging inlet on thevehicle. Doing so may result in elec‐trocution.
• Comply with the following in order toprevent electrical shock when charg‐
ing: - Use a waterproof charger
- Make sure to not touch the charg‐ ing connector and charging plug
when your hand is wet
- Do not charge when there is light‐ ning
- Do not charge when the charging connector and plug is wet
WARNING
nCharging cable
(Continued)
(Continued)
•Immediately stop charging whenyou find abnormal symptoms(smell, smoke).
•Replace the charging cable if thecable coating is damaged to pre‐vent electrical shock.
•When connecting or removing thecharging cable, make sure to holdthe charging connector handle andcharging plug.If you pull the cable itself (withoutusing the handle), the internalwires may disconnect or get dam‐aged. This may lead to electricshock or fire.
WARNING
nCooling fan
Do not touch the cooling fan whilevehicle is charging. When the vehicleis switched OFF while charging, thecooling fan inside the motor com‐partment may automatically oper‐ate.

4. Remove any dust on the chargingconnector and charging inlet.
5. Hold the charging connector handle. Then, insert it into the charging in‐
let, until you hear a click sound. If it
is not fully connected, a bad con‐
nection between the charging con‐
nector and the charging terminals
may cause a fire.

6. Check if the charging cable connec‐ tion indicator of the high voltage
battery in the instrument cluster is
turned ON.
Charging does not occur when the
indicator is OFF. When the charging
connector is not connected proper‐
ly, reconnect the charging cable to
charge.
NOTICE
•The charging is in progress only
with the shift lever is in P (Park).
Charging the battery with the
Engine Start/Stop button in the
ACC position is possible. Howev‐
er, it may discharge the 12-V
battery. Thus, if possible, charge
the battery with the Engine
Start/Stop button in the OFF po‐
sition.
•Moving the shift lever from P
(Park) to R (Reverse)/
N(Neutral)/D (Drive) stops the
charging process. To restart the
charging process, move the shift
lever to P (Park), press the En‐
gine Start/Stop button to the
OFF position, and disconnect the
charging cable. Then, connect
the charging cable.

How to disconnect normal charger
1. The vehicle doors must be unlockedin order to be able to disconnect
the charging connector. A lock sys‐
tem prevents charger cable discon‐
nection when the vehicle's doors
are locked.
