Electric Vehicle
An electric vehicle is driven using a
battery and an electric motor. While
general vehicles use an internal
combustion engine and gasoline as fuel,
electric vehicles use electrical energy
that is charged inside the high voltage
battery. As a result, electric vehicles are
eco-friendly in that they do not require
fuel and do not emit exhaust gases.
Characteristics of Electric
Vehicles
1. It is driven using the electrical energy that is charged inside the high voltage
battery. This method prevents air
pollution since fuel, like gasoline, is
not required, negating the emission of
exhaust gases.
2. A high performance motor is used in the vehicle as well. Compared to
standard, internal combustion engine
vehicles, engine noise and vibrations
are much more minimal when driving.
3. When decelerating or driving downhill, regenerative braking is
utilized to charge the high voltage
battery. This minimizes energy loss
and increases the distance to empty.
4. When the battery charge is not
sufficient, AC charge, DC charge and
trickle charge are available. (Refer to
“Charge Types for Electric Vehicle” for
details.)
Information
What does regenerative braking do?
It uses an electric motor when decelerating and braking and transforms kinetic
energy to electrical energy in order to
charge the high voltage battery. (Torque
is applied in the opposite direction when
decelerating to generate braking force and
electric energy.)
Battery Information
• 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 or the high
voltage battery is being charged.

Main Components of Electric
Vehicle
• On-Board Charger (OBC) : A device
that charges the high voltage battery
by converting AC power of the power
grid to DC power.
• Inverter : Transforms direct current
into alternate current to supply power
to the motor, and transforms alternate
current into direct current to charge
the high voltage battery.
• LDC : Transforms power from the high
voltage battery to low voltage (12 V) to
supply power to the vehicle (DC-DC).
• VCU : Control the various controls on
the vehicle.
• Motor : Uses electrical energy stored
inside the high voltage battery to drive
the vehicle (functions like an engine in
a standard vehicle).
• Reduction gear : Delivers rotational
force of the motor to the tires at
appropriate speeds and torque.
• High voltage battery (lithium-ion
battery) : Stores and supplies power
necessary for the electric vehicle
to operate (12 V auxiliary battery
provides power to the vehicle features
such as lights and wipers).

WARNING
• Do not intentionally remove
or disassemble high voltage
components and high voltage
battery connectors and wires. Also,
be careful not to damage high
voltage components and the high
voltage battery. It may cause serious
injury and significantly impact the
performance and durability of the
vehicle.
• When inspection and maintenance
is required for high voltage
components and the high voltage
battery, contact an authorized
HYUNDAI dealer.
High Voltage Battery
(lithium-ion battery)
• The charge amount of the high
voltage battery may gradually
decrease when the vehicle is not
being driven.
• The battery capacity of the high
voltage battery may decrease when
the vehicle is stored in high/low
temperatures.
• Distance to empty may vary depending on the driving conditions
(such as outside temperature), even
if the charge amount is the same.
The high voltage battery may expend
more energy when driving at high-
speed or uphill. These actions may
reduce the distance to empty.
• The high voltage battery is used when
using the air-conditioner / heater.
This may reduce the distance to
empty. Make sure to set moderate
temperatures when using the air-
conditioner/heater.

NOTICE
• Ambient temperature affects the tire pressure (about 7kPa (1 psi) for every
12°F (7°C) change). If colder temperatures are anticipated, it is permissible to
increase cold tire inflation pressure by up to 20 kPa (3 psi) over the specification.
If extreme temperature changes are expected, be sure to check and adjust tire
pressure accordingly.
• Tire inflation pressure decreases with higher elevation, and increases with lower
elevation (about 10 kPa (2.4 psi) for every mile (or kilometer) elevation change).
Be sure to check and adjust tire pressure accordingly when driving through
changing elevations.
• Do not exceed the maximum inflation pressure, as found on the sidewall of the
tire(s).
CAUTION
When replacing tires, ALWAYS use the same size, type, brand, construction and
tread pattern supplied with the vehicle. If not, it can damage the related parts or
make it work irregularly.

NOTICE
Driving with wheels and tires with
different sizes may cause the ESC
system to malfunction. Before replacing
tires, make sure all four tires and wheels
are the same size. Never drive the
vehicle with different sized wheels and
tires installed. ESC OFF usage
When Driving
The ESC OFF mode should only be used
briefly to help free the vehicle if stuck in
snow or mud, by temporarily stopping
operation of ESC, to maintain wheel
torque.
To turn ESC off while driving, press the
ESC OFF button while driving on a flat
road surface.
NOTICE
To prevent damage to the reduction gear: • Do not allow wheel(s) of one axle to
spin excessively while the ESC, ABS,
and Parking Brake warning lights
are displayed. The repairs would not
be covered by the vehicle warranty.
Reduce motor power and do not spin
the wheel(s) excessively while these
lights are displayed.
• When operating the vehicle
on a dynamometer, make sure
ESC is turned off (ESC OFF light
illuminated).
Information
• Turning ESC off does not affect ABS or standard brake system operation.
• Select 0 step of the regenerative
braking system and depress the brake
pedal around 10 times to efficiently apply brake disc cleaning.
Brake disc cleaning may decrease the
driving distance by restraining the
regenerative braking system. After
brake disc cleaning, the regenerative
braking system may be restored.
If the regenerative braking system
is not restored after the brake disc cleaning, have the vehicle inspected by
an authorized HYUNDAI dealer.

Drive Mode
ONE1061021
Drive mode may be selected according
to the driver's preference or road condition.
ONE1061041
The mode changes whenever the driver
pushes the DRIVE MODE button. NORMAL mode
Normal mode is a driving mode used
when driving on general roads, city
center and highways. ECO mode
ECO mode is a driving mode improving
energy efficiency by controlling motors
and reduction gear.
Electric energy efficiency varies
according to the driver's driving habit
and road condition. •
When ECO mode is selected, the
ECO indicator will illuminate on the
instrument cluster and the color of the mood lamp will change.
• When ECO mode is activated:
- The acceleration response may be slightly reduced if the accelerator
pedal is depressed moderately.
- The air conditioner performance may be limited.
The above situations are normal
conditions when ECO mode is
activated to help improve electric
energy efficiency.
Limitations of ECO mode
If the following conditions occur while
ECO mode is operating, the system
operation is limited even though there is
no change in the ECO indicator. • When coolant temperature is low:
The system will be limited until motor
performance becomes normal.
• When driving up a hill:
The system will be limited to gain
power when driving uphill because
motor torque is restricted.

• When driving up a hill:
The system will be limited to gain

SPORT mode
SPORT mode is a driving mode
improving driving performance by fixing
AWD system and controlling reduction
gear.
In SPORT mode, the electric energy
efficiency may decrease. • When SPORT mode is selected, the
SPORT indicator will illuminate on the
instrument cluster and the color of the mood lamp will change.
• Whenever the vehicle is restarted,
the drive mode will revert back to
NORMAL mode. If SPORT mode is
desired, re-select SPORT mode.
SNOW mode
SNOW mode is a driving mode improving
driving performance by changing
the engagement status of the motor
according to the situation required. Auto
changing the driving mode(2WD/AWD)
helps improve driving stability. • Press and hold the drive mode button
to select SNOW mode.
• When SNOW mode is selected, the
SNOW indicator will illuminate on the
instrument cluster and the color of the mood lamp will change.
• When SNOW mode is activated, the
driving power is distributed to four
wheels automatically, increasing the
stability of the vehicle.
NOTICE
• Depress the accelerator pedal softly
on the snow and the ice.
• Keep the distance from the vehicle in
the front.
• Prevent rapid acceleration,
deceleration and steering control.
Abrupt driving on the snow may
cause the accident.
