7. Check if the charging indicator light of the high voltage battery
on the instrument cluster is turned
ON. Charging is not done when the
charging indicator lamp is OFF.
When the charging connector and
charging plug are not connected
properly, reconnect the charging
cable to charge.
Information
• Even though charging is possible with
the ignition switch in the ON/START
position, for your safety, start charging
when the ignition switch is in the
LOCK/OFF position and the vehicle
shifted to P (Park). After charging
has started, you can use electrical
components such as the radio by
placing the ignition switch in the ACC
or ON position.
• During AC charging, the radio
reception may be bad.
• Moving the shift button from P (Park)
to R (Reverse)/N(Neutral)/D (Drive)
stops the charging process.
To restart the charging process, move
the shift button to P (Park), place the
ignition switch to the LOCK/OFF
position, and disconnect the charging
cable. Then, connect the charging cable.

Information
To control the temperature of the high
voltage battery while charging or when
the battery temperature is high, the air
conditioner is used to cool down the
battery. It may generate noise or vibration
from operation of the air conditioner
compressor and cooling fan, but it is a
normal condition when charging the high
voltage battery. Also, the air conditioner’s
performance may be degraded due to
operation of the cooling system to charge
the high voltage battery. This is a normal
condition.
Information
Even though charging is possible with
the Start/Stop button in the ON/START
position, for you safety, start charging
when the Start/Stop button is in the
OFF position and the vehicle shifted to P
(Park). After charging has started, you
can use electrical components such as the
radio by pressing the Start/Stop button to
the START or ON position.
During charging, the gear cannot be
shifted from P (Park) to any other gear.

10. After charging has started, the estimated charging time is displayed
on the instrument cluster for about 1
minute.
If you open the driver seat door while
charging, the estimated charging time
is also displayed on the instrument
cluster for about 1 minute.
When scheduled charging is set, the
estimated charging time is displayed
as “--” .
Information
Depending on the condition and durability
of the high voltage battery, charger
specifications, and ambient temperature,
the time required for charging the battery
may vary.

Charging connector AUTO/LOCK mode
The charging connector is locked in the
inlet at a different period according to
which mode is selected.
• LOCK mode : The connector locks
when the charging connector is plugged
into the charging inlet.
• AUTO mode : The connector locks
when charging starts.
For more details, refer to “Charging
Connector AUTO/ LOCK Mode” in this
chapter.

Starting the Vehicle
Vehicles with smart key system
1. Carry the smart key or leave it inside the vehicle.
2. Make sure the parking brake is firmly applied.
3. Make sure the shift button is in P (Park). With the shift button in N
(Neutral), you cannot start the vehicle.
4. Depress the brake pedal.
5. Press the Engine Start/Stop button. If the hybrid system starts, the “
”
indicator will come on.
Whether the engine is cold or warm, it
should be started without depressing
the accelerator.
After following the start procedures,
“
” indicator on the instrument
cluster will turn on. For more details,
please check chapter 6.
ECONOMICAL and SAFE OPERATION of
Hybrid system
• Drive smoothly. Accelerate at a moderate rate and maintain a steady
cruising speed. Do not make “jack-
rabbit” starts. Do not race between
stoplights.
Avoid heavy traffic whenever possible.
Always maintain a safe distance
from other vehicles so you can
avoid unnecessary braking. This also
reduces brake wear out.
• The regenerative brake generates energy when the vehicle decelerates.
• When the hybrid battery power is low, the hybrid system automatically
recharges the hybrid battery.
• When the engine is running with the shift button in N (Neutral), the hybrid
system cannot generate electricity.
The hybrid battery cannot recharge
with the shift button in N (Neutral).
Information
In the hybrid system, the engine
automatically 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
condition 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 under the floor. 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
compartment. None of these sounds
indicate a problem. These are normal
characteristics 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.
DRIVING THE HYBRID VEHICLE

Foreword/Starting your Hybrid/Plug-in hybrid vehicle1-56
Warning and Indicator Lights
Ready indicator
This indicator illuminates:
When the vehicle is ready to be driven. -
ON : Normal driving is possible.
- OFF : Normal driving is not possible, or a problem has occurred.
When the ready indicator goes OFF,
there is a problem with the system. If this
occurs, have your vehicle inspected by
an authorized HYUNDAI dealer.
EV mode indicator
This indicator illuminates:
When the vehicle is driven by the electric
mo
tor.
Charging Cable Connection
Indicator (Plug-in hybrid
vehicle)
This indicator illuminates in red when the
charging cable is connected.
Service warning light
This warning light illuminates:
• When you set the ignition switch or the E
ngine Start/Stop button to the
ON position.

- The service warning light illuminates
for approximately 3 seconds and
then turns off when all checks have
been performed.
• When there is a problem with the hybrid vehicle control system or
hardware.
When the warning light illuminates while
driving, or does not go OFF after starting
the vehicle, have the vehicle inspected
by an authorized HYUNDAI dealer.
Regenerative brake warning
light
(yellow)
This warning light illuminates:
When the regenerative brake does not
oper
ate and the brake does not perform
well. This causes the Brake Warning
light (red) and Regenerative Brake
Warning Light (yellow) to illuminate
simultaneously.
If this occurs, drive safely and have
your vehicle inspected by an authorized
HYUNDAI dealer. The operation of the
brake pedal may be more difficult than
normal and the braking distance may
increase.

e-Handling (Electrically Assisted
Handling Performance)/e-EHA
(Electrically Evasive Handling
Assist)
e-Handling controls the electric motor
while turning around to improve the
handling performance, driving safety,
convenience and ride comfort.
e-EHA connects FCA (Forward Collision
Avoidance Assist) and the electric motor
to provide assists to avoid collision
so that prompt collision avoidance is
available while FCA warning appears.
à e-Handling stands for Electrically
Assisted Handling Performance.

à e-EHA means Electrically Evasive
Handling Assist.
Operation condition
e-Handling starts to work by identifying
enter or exit condition if the driver
operates the steering wheel over a
certain level when the vehicle speed is
between 24 mph and 74 mph.
e-EHA operates if there is urgent steering
wheel operation while FCA (Forward
Collision Avoidance Assist) warning
appears
Operation cancel
- When ESC operates
- When ABS operates
CAUTION
The system does not work under the
following conditions.
- When the ESC operation stop light
is on
- When it does not work due to a
malfunction of electronic device
- When the manual transmission mode
is set
- The gear shift is not in D (Drive)
Information
Please refer to the chapter 6 “Paddle shift
(manual transmission mode) of automatic
transmission (electronic transmission
button)”
