•Vehicle Control Unit (VCU) : Controls the various controllers and sensors on the
vehicle.
• Motor : Uses electricity accumulated on the high voltage battery to drive the vehicle
(same role as an engine in gasoline vehicles).
• Gear: Delivers the 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. (The separately installed 12 V battery provides power to
the vehicle when the vehicle is in ACC or OFF.)
WARNING • Do not remove or disassemble any high voltage battery’s connectors and wires. Doing so may lead to accidents, such as electric shock, and result in serious injury and
significantly degrade the vehicle’s performance and durability.
• When the high voltage battery or its related components require inspection and maintenance, contact an authorized HYUNDAI dealer.

Precautions When Using the High Voltage Battery
Precautions for high voltage battery when driving and storing the vehicle are as follows:
CAUTION • Keep the gauge of the high voltage battery from going below 10 %. Storing the vehicle while the battery level is too low for a long time may damage the battery or reduce the
battery’s capacity.
• If a collision occurs and the vehicle is impacted, have the vehicle inspected by an authorized HYUNDAI dealer and check the battery connection status.
• Using the V2L function may reduce the driving distance due to the use of high voltage battery energy, and repeated use of the V2L function may impact battery life.
• Frequent use of DC charging may impact battery life.

• The high voltage battery level may reduce naturally even if the vehicle is not driven.
• Storing the vehicle in temperatures that are too hot or cold may degrade the battery performance.
• The distance to empty or power output may vary depending on the driving conditions, such as the outside temperature. Driving on highway at high speeds or uphill will
increase battery consumption, resulting in a shorter distance to empty.
• If you use the air conditioner or heater, which is powered by the high voltage battery, the distance to empty will be reduced. Maintain reasonable temperature when using
the air conditioner or heater to maximize distance to empty.
• Depending on the vehicle’s period of use, natural degradation of the battery may occur that reduces distance to empty over long period of vehicle life. When the charge

Understanding virtual engine sound system
Electric vehicles do not use an internal combustion engine, so there is no engine noise
while driving. The Virtual Engine Sound System (VESS) generates engine sound to make
pedestrians aware of the approaching vehicle when driving.
• If the vehicle is in the ready ( ) mode and the gear is not in P (Park), the VESS is operated.
• When the gear is shifted to R (Reverse), an additional warning sound will be heard.
CAUTION • Be aware that the vehicle does not make engine noise while driving.
• Pay attention to the surrounding environment and drive carefully.
• After parking or waiting for a traffic light, please check around for children, or other obstacles before departure.
• When reversing, check directly behind you before driving. Pedestrians may not be able to recognize vehicle sounds.

Checking Electric Vehicle Driving Information
During vehicle operation, the instrument cluster displays the main information, such as
distance to empty, real-time energy status, battery charge level, and warning messages,
via the user interface and indicators.
Factors affecting the distance to empty
The distance to empty refers to the distance that can be driven by the current charged
battery level and is displayed on the bottom of the instrument cluster while driving the
electric vehicle.
B0002901
The distance to empty vary depending on many factors such as driving habits, power
usage, driving conditions, and high voltage battery. The distance to empty may be
increased or decreased from the certified figures as it reflects all the factors
comprehensively. Check the distance to empty considering the following:

Stop vehicle and check power
supply
This warning 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 inspected.
Check electric vehicle system
This warning message is displayed when
there is a problem with the electric
vehicle control system.
Refrain from driving when the warning
message is displayed.
In this case, have the vehicle inspected by
an authorized HYUNDAI dealer.
Check active air flap system
OOSEV040510L
This warning message is displayed in the
following situations:
• There is a malfunction with the actuator flap
• There is a malfunction with the actuator air flap controller
• The air flap does not open
When all of the above conditions are
fixed, the warning will disappear.
Check virtual engine sound system
OOSEV040512L
This message is displayed when there is a
problem with the Virtual Engine Sound
System (VESS).
In this case, have the vehicle inspected by
an authorized HYUNDAI dealer.

Information Virtual Engine Sound System (VESS)
VESS generates virtual engine sound to make
pedestrians to aware. VESS operates when the
vehicle can be driven. When the vehicle in P
(parking) gear status, VESS doesn't work.

CAUTION Always check your surroundings while
driving, backing up, or before driving
from a stop because your electric vehicle
does not make vehicle sounds.

Emergency starting
B6000501
If the smart key battery is weak or the
smart key does not work correctly, press
the Start/Stop button with the smart key
in the direction of the illustration shown
above.
Turning Off the Vehicle
1. Stop the vehicle and depress the brake pedal fully.
2. Shift to P (Park).
3. Press the Start/Stop button to the OFF position and apply the parking brake.
4. Make sure the indicator is turned off on the instrument cluster.
CAUTION If the indicator on the instrument
cluster is still on, the vehicle is not turned
off and can move when the gear is in any
position except P (Park).
