When the hybrid system is turned ON,
the gasoline engine may run or may not.
In this situation, you may feel a vibration.
This does not indicate a malfunction.
When the “
” indicator illuminates, the
hybrid system is ready to begin driving.
Even if the engine is off, you can operate
the vehicle as long as the “
” indicator
is illuminated.
NOTICE
The hybrid system contains many
electronic components. High voltage
components, such as cables and other
parts, may emit electromagnetic waves.
Even when the electromagnetic cover
blocks electromagnetic emissions,
electromagnetic waves may have an
effect on electronic devices. When your
vehicle is not used for a long period of
time, the hybrid system will discharge.
You need to drive the vehicle several
times a month. Drive at least for 1 hour
or 10 miles. When the hybrid battery
is discharged, or when it is impossible
to jump start the vehicle, contact your
authorized HYUNDAI dealer.
WARNING
• When you start the hybrid system
with the shift button in P (Parking),
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 hybrid system
or locate the shift button in P (Park).
When you depress the accelerator
pedal by mistake, or when the shift
button is not in P (Park), the vehicle
will abruptly move, possibly resulting
in serious injury or death.
Virtual Engine Sound System (VESS)
The Virtual Engine Sound System
generates engine sound for pedestrians
to hear vehicle sound because there is
limited sound while motor power is used.
• When the engine is running, the gear
shift button is not in P (Park), the VESS
will operate.
• When the gear is shifted to R (Reverse), an additional warning
sound will be heard.
What does regenerative braking do?
It uses an electric motor when
decelerating and when braking and
transforms 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 lead 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 automatically charged when the
vehicle is in the ready (
) mode.

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

For more information, please refer to
the Infotainment 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 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+ periodically activates according
to the auxiliary battery 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 status
to prevent overdischarge of the auxiliary
battery.

01
1-55
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 vehicle 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 devices are used.
• If the Aux. Battery Saver+ function was
activated, the high voltage battery level
may have decreased.
System Setting
OAEPHQ049855LOAEPHQ049855L
The driver can activate the Aux. Battery
Saver+ function by placing the ignition
switch to the ON position and by
selecting:
‘User Settings
Ÿ Other
Ÿ Aux. Battery
Saver+’
The Aux. Battery Saver+ function
deactivates, when the driver cancels the
system setting.
WARNING
ONX4EPHQ011025LONX4EPHQ011025L
When the function is activating, the
charging indicator lamp will be on in
red and high voltage electricity will be
flowing in the vehicle. Do not touch
the high voltage electric wire (orange),
connector, and all electric components
and devices. This may cause electric
shock and lead to injuries. Also, do not
modify your vehicle in any way. This
may affect your vehicle performance
and lead to an accident.
