KIA Optima Hybrid 2013 - Manual (Page 373)

H2
Kia Hybrid-Electric Vehicle (HEV) uses
a gasoline engine and an electric
motor for power. The electric motor is
run from a 270V high voltage HEV bat-
tery.
The HEV computer decides when to
use the engine and when to use elec-
tric motor, according to driving condi-
tions. At times, both are used simulta-
neously.
By turning off the engine under cer-
tain conditions and using the electric
motor alone, the HEV system 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 decelerat-
ing by using regenerative braking. Hybrid System Display
Many of the displays provide information
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 vehi-
cle is driven economically, the ECO Level
rises. When the vehicle is driven in EV
mode, there is a reduction in carbon diox-
ide (CO2) emissions.
The Total ECO Score display indicates
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 number 4.
If you drive economically, the ECO Level
will increase. However, if you do not drive
economically, the ECO Level will
decrease.
