Virtual Engine Sound System
(VESS)
The Virtual Engine Sound System
generates engine sounds for pedes-
trians to hear vehicle sound because
there is limited sound while electric
power is used.
What Does Regenerative
Braking Do?
It uses an electric motor when decel-
erating and when braking and trans-
forms kinetic energy to electrical
energy in order to charge the high
voltage battery.
Battery
Hybrid vehicle
- The vehicle is composed of a
high voltage battery that drives
the motor and air conditioner, and
an integrated 12V lithium ion
polymer battery with the HEV
battery that drives the lamps,
wipers, and audio system.
- The integrated 12V battery is
automatically charged when the
vehicle is in the ready ( )
mode.
Plug-in hybrid vehicle
- The vehicle is composed of a
high voltage battery that drives
the motor and air-conditioner,
and an auxiliary battery (12 V)
that drives the lamps, wipers, and
audio system.
- The auxiliary battery is automati-
cally charged when the vehicle is
in the ready ( ) mode.
When you start the hybrid
system with the shift lever in
P (Park), the " " indicator
illuminates on the instrument
cluster. The driver can drive
the vehicle, even when the
gasoline engine is off.
When you leave the vehicle,
you should turn OFF the vehi-
cle and place the shift lever in
P (Park). If you depress the
accelerator pedal by mistake,
or when the shift lever is not in
P (Park), the vehicle will
abruptly move, possibly result-
ing in serious injury or death.
WARNING

H33
Plug-in hybrid mode indicator
CD (Charge Depleting, Electric)
mode : The high-voltage (hybrid)
battery is used to drive the vehicle.
AUTO mode : CD mode and CS
mode are selected automatically
depending on road conditions.
CS (Charge Sustaining, Hybrid)
mode : The high-voltage (hybrid)
battery and gasoline engine is
used to drive the vehicle.
Information
Even when the battery charging rate
is high and driving in electric mode is
possible, engine may turn on in some
areas to protect the system.
Infotainment system Screen
(Plug-in hybrid vehicle)
(if equipped)
Press [PHEV] on the [Home] screen
or the [All menus] screen and the
menus related to plug-in hybrid
([ECO driving], [Energy information],
[EV range], [Set charging times],

are displayed.
For more information, please refer
to the Infotainment System
Manual that was separately sup-
plied with your vehicle.
Aux. Battery Saver+
(Plug-in hybrid vehicle)
The Aux. Battery Saver+ is a function
that monitors the charging status of
the 12 V auxiliary battery.
If the auxiliary battery level is low, the
main high voltage battery charges
the auxiliary battery.
Information
The Aux. Battery Saver+ function will
be ON when the vehicle is delivered. If
the function is not needed, you may
turn it off in the Users Settings mode
on the cluster. For more information,
refer to the following page.

Mode
Cycle Mode :
When the vehicle is OFF with all
doors, hood and liftgate closed, the
Aux. Battery Saver+ activates
according to the auxiliary battery
status.
Automatic Mode :
When the Engine Start/Stop button
is in the ON position with the charg-
ing connector plugged in, the func-
tion activates according to the auxil-
iary battery status to prevent
overdischarge of the auxiliary bat-
tery.Information
• The Aux. Battery Saver+ activates
maximum of 20 minutes. If the Aux.
Battery Saver+ function activates
more than 10 times consecutively
when in the automatic mode, the
function will stop activating, judg-
ing that there is a problem with the
auxiliary battery. In this case, drive
the vehicle for some period of time
or if the auxiliary battery returns to
normal, the function will start acti-
vating.
• The Aux. Battery Saver+ function
cannot prevent battery discharge if
the auxiliary battery is damaged,
worn out, used as a power supply or
unauthorized electronic devises are
used.
• If the Aux. Battery Saver+ function
was activated, a message will be dis-
played on the instrument cluster
and the high voltage battery level
may have decreased.
System Setting
The driver can activate the Aux.
Battery Saver+ function by placing
the Engine Start/Stop button to the
ON position and by selecting:
'User Settings →Other → Aux.
Battery Saver+'
The Aux. Battery Saver+ function
deactivates, when the driver cancels
the system setting.
