2018 Hyundai Ioniq Hybrid Engine

H27
Information
In the hybrid system, the engine auto-
matically runs and stops. When the
hybrid system operates, the " "
indicator is illuminated.
In the following situation, the engine
may operate automatically.
- When the engine is ready to run
- When the hybrid battery is being
charged
- Depending on the temperature con-
dition of the hybrid battery
Special Features
Hybrid vehicles sound different than
gasoline engine vehicles. When the
hybrid system operates, you may
hear a sound from the hybrid battery
system behind the rear seat. If you
apply the accelerator pedal rapidly,
you may hear an unconventional
sound. When you apply the brake
pedal, you may hear a sound from
the regenerative brake system.
When the hybrid system is turned off
or on, you may hear a sound in the
engine compartment. If you depress
the brake pedal repeatedly when the
hybrid system is turned on, you may
hear a sound in the engine compart-
ment. None of these sounds indicate
a problem. These are normal charac-
teristics of hybrid vehicles.If any of following occur, it's a normal
condition if you hear a motor sound
in the engine compartment:
- After turning off the hybrid system,
the brake pedal is released.
- When the hybrid system is turned
off, the brake pedal is applied.
- When the driver door is opened.
When the hybrid system is turned
ON, the engine may run or may not.
In this situation, you may feel a vibra-
tion. This does not indicate a mal-
function. When the “ ” indicator
illuminates, the hybrid system is ready
to start. Even if the engine is off, you
can operate the vehicle as long as the
“ ” indicator is illuminated.

The hybrid system contains many
electronic components. High volt-
age components, such as cables
and other parts, may emit electro-
magnetic waves. Even when the
electromagnetic cover blocks elec-
tromagnetic emissions, electro-
magnetic waves may have an effect
on electronic devices. When your
vehicle is not for a long period of
time, the hybrid system will dis-
charge. You need to drive the vehi-
cle several times a month. We rec-
ommend driving at least for 1 hour
or 16 km. When the hybrid battery is
discharged, or when it is impossi-
ble to jump start the vehicle, con-
tact your HYUNDAI dealer.
Virtual Engine Sound System
(VESS)
The Virtual Engine Sound System
generates engine sound for pedestri-
ans to hear vehicle sound because
there is limited sound while motor
power is used.
• The VESS may be turned ON or
OFF by pressing the VESS button.
(if equipped)
• If the vehicle is moving at low
speed, the VESS will operate.
• When the gear is shifted to R
(Reverse), an additional warning
sound will be heard.
NOTICE
•When you start the hybrid
system with the shift lever in
P (Parking), the “ ” indica-
tor illuminates on the instru-
ment cluster. The driver can
drive the vehicle, even when
the engine is stopped.
•When you leave the vehicle,
you should turn OFF the
hybrid system or locate the
shift lever in P (Park). When
you depress the accelerator
pedal by mistake, or when the
shift lever is not in P (Park),
the vehicle will abruptly move,
possibly resulting in serious
injury or death.

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.

Hybrid Battery SOC
(State of Charge) Gauge
This gauge indicates the remaining
hybrid battery power. If the SOC is
near the "0 or 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 gauge is near the "0 or L (Low)"
level, we recommend the vehicle be
checked by an authorized HYUNDAI
dealer.
Plug-in Hybrid Mode
(Plug-in hybrid vehicle)
EV/HEV Button
Pressing the [EV/HEV] button
changes the plug-in hybrid system
modes, between Electric (CD) mode
and Hybrid (CS) mode.
Each time the mode is changed a
corresponding indicator is displayed
on the instrument cluster as follows.

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.
