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.
Kia HYBRID SYSTEM
OTFH044300N
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.
