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 240V 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.

Kia hybrid system notifies the drivers
of energy flow in various operating
modes. The operating condition of
the vehicle can be shown in the fol-
lowing eleven modes.
Vehicle Stop
The mode means the vehicle at stop.
(There is no energy flow.)
EV Propulsion
Electric power is used to move the
vehicle. (Battery ➞Wheel)
Power Assist
Electric and Engine power are used
to move the vehicle.

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 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 7.
✽ ✽ NOTICE
When the hybrid system is in ready
mode, the engine will automatically
start and stop as needed.
The " " symbol will illuminate in
the cluster when the system is oper-
ational.
CAUTION - Extended
cranking
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.

H9
The Hybrid battery uses high voltage
top operate the electric motor and
other components and other compo-
nents. 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 is
recommended to be serviced by an
authorized Kia dealer.
WARNING - High voltage
components
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 the fuses in the
engine compartment, never
touch the HPCU. The HPCU car-
ries high voltage. Touching the
HPCU could result in electrocu-
tion, serious injury, or death.

CAUTION - High Voltage
Battery Damage
When loading your vehicle, be careful of transporting items ina manner that could damage thehigh voltage battery. Do notstore items on top of the highvoltage battery or overload thetrunk area. Such actions mayultimately damage the high volt-age battery unit.
CAUTION - Carrying
Liquids in Trunk
Do not load large amounts of liquid in open containers in thevehicle. If spilled onto the HEVbattery, the liquid may cause ashort or further damage to thebattery.

H11
WARNING- Batteryelectrolyte
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- After-market
battery charger
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 high waters as this may result in your vehicle becom-
ing saturated 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 - 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.CAUTION - Cleaning
Engine
When you clean the engine compartment, do not washusing water. Water may causeelectric arcing to occur anddamage electronic parts andcomponents.
