Unlock Charging Connector in
Emergency
If the charging connector does not
disconnect due to battery discharge
and failure of the electric wires, open
the hood and slightly pull the emer-
gency cable. The charging connector
will then disconnect .
Precautions for Portable
Charger (ICCB: In-Cable Control
Box)
• Use the portable charger that is
certified by HYUNDAI Motors.
• Do not try to repair, disassemble,
or adjust the portable charger.
• Do not use an extension cord or
adapter.
• Stop using immediately when fail-
ure occurs.
• Do not touch the plug and charging
connector with wet hands.
• Do not touch the terminal part of
the normal charging connector and
the normal charging inlet on the
vehicle.
• Do not connect the charging con-
nector to voltage that does not
comply with regulations.
• Do not use the portable charger if it
is worn out, exposed, or there
exists any type of damage on the
portable charger.
• If the ICCB case and normal charg-
ing connector is damaged, cracked,
or the wires are exposed in any way,
do not use the portable charger.• Do not let children operate or touch
the portable charger.
• Keep the control box free of water.
• Keep the normal charging connec-
tor or plug terminal free of foreign
substances.
• Do not step on the cable or cord.
Do not pull the cable or cord and
do not twist or bend it.
• Do not charge when there is light-
ning.
• Do not drop the control box or
place a heavy object on the control
box.
• Do not place an object that can
generate high temperatures near
the charger when charging.
• Charging with the worn out or dam-
aged household electric outlet can
result in a risk of electric shock. If
you are in doubt to the household
electric outlet condition, have it
checked by a licensed electrician.
• Stop using the portable charger
immediately if the household elec-
tric outlet or any components is
overheated or you notice burnt
odors.

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
- 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 auto-
matically charged when the vehicle
is in the ready ( ) mode.
• Plug-in hybrid vehicle
- The vehicle is composed of a
highvoltage 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.
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.

Plug-in hybrid mode indicator
• CD (Charge Depleting, Electric)
mode : The high-voltage (hybrid)
battery is used to drive the vehicle.
• 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.
AVN 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 Multimedia System Manual
that was separately supplied 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 aux-
iliary battery level is low, the main
high voltage battery charges the aux-
iliary 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 tailgate closed, the
Aux. Battery Saver+ periodically acti-
vates according to the auxiliary bat-
tery status.
• Automatic Mode :
When the ignition switch is in the ON
position with the charging connector
plugged in, the function activates
according to the auxiliary battery sta-
tus to prevent overdischarge of the
auxiliary battery.Information
• The Aux. Battery Saver+ activates
maximum of 20 minutes. If the Aux.
Battery Saver+ function activates
more than 10 times consecutively, in
the Automatic Mode the function
will stop activating, judging that
there is a problem with the auxiliary
battery. In this case, drive the vehi-
cle for some period of time. The
function will start activating if the
auxiliary battery returns to normal.
• 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 ignition switch to the ON position
and by selecting:
'User Settings →Other Features →
Aux. Battery Saver+'
The Aux. Battery Saver+ function
deactivates, when the driver cancels
the system setting.

OAEE046143L
When the function is activating,
the third Charging Indicator
Lamp will blink and high voltage
electricity will be flowing in the
vehicle. Do not touch the high
voltage electric wire (orange),
connector, and all electric com-
ponents and devices. This may
