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

Hybrid System Gauge
The hybrid system gauge indicates
whether the current driving condition
is fuel efficient or not.
CHARGE :
Shows that the energy made by
the vehicle is being converted
to electrical energy. (Regenerated
energy)
ECO :
Shows that the vehicle is being
driven in an Eco-friendly manner.
POWER :
Shows that the vehicle is exceeding
the Eco-friendly range.According to the hybrid system
gauge area, the "EV" indicator comes
on or off.
- "EV" indicator ON : Vehicle is driven
using the electric motor or the
gasoline engine is stopped.
- "EV" indicator OFF : Vehicle is driv-
en using the gasoline engine.
Battery State of Charge (SOC)
This gauge indicates the remaining
hybrid battery power. If the SOC is
near the "L (Low)" level, the vehicle
automatically operates the engine to
charge the battery.
However, if the Service Indicator ( )
and Malfunction Indicator Lamp (MIL)
( ) turn on when the SOC (State of
charge) gauge is near the "L (Low)"
level, have the vehicle checked by an
authorized HYUNDAI dealer.
❈The actual cluster in the vehicle
may differ from the illustration.

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],
[Charging stations], [Petrol stations])
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.
