2019 Hyundai Ioniq Hybrid BATTERY CHARGE

H29
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 RegenerativeBraking 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 ahigh 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 ahigh 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.

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.
Hybrid Battery SOC (State of Charge) Gauge
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.

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.

Stop vehicle and check power
supply
This message is displayed when a
failure occurs in the power supply
system.
In this case, park the vehicle in a
safe location and tow your vehicle to
the nearest authorized HYUNDAI
dealer and have the vehicle inspect-
ed.
Stop vehicle to charge battery/Park with engine On to chargebattery
Either message is displayed when
the hybrid battery power (SOC) level
is low.
In this case, park the vehicle in a
safe location and wait until the hybrid
battery is charged.
You can increase the hybrid battery
charging rate by holding the acceler-
ator pedal to the floor with transmis-
sion in P. The engine will rev high but
it will be limited for charging purpose
when you hold the pedal to the floor.
Refuel to prevent Hybrid batterydamage
This message is displayed when the
fuel tank is nearly empty.
You should refill the fuel tank to pre-
vent hybrid battery damage.
