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).

à OBC : On-Board Charger

à LDC : Low Voltage DC-DC Converter

à VCU : Vehicle Control Unit
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.

WARNING
ONE1Q011038
When the function is activating the
indicator lamp will illuminate and high
voltage electricity will be flowing in the
vehicle. Do not touch the high voltage
electric wire (orange), connector, and
all electric components and devices.
This may cause electric shock and lead
to injuries. Also, do not modify your
vehicle in any way. This may affect your
vehicle performance and lead to an
accident.

fastening.
If you start to drive without the seat belt
fastened or you unfasten the seat belt
when you drive under 12 mph (20 km/h)
or stop, the corresponding warning light
will illuminate.
If you start to drive without the seat
belt fastened or you unfasten the seat
belt when you drive 12 mph (20 km/h)
and faster, the warning light will blink
and warning chime will sound for
approximately 100 seconds.
When the seat belt is unfastened during
driving, the warning light will illuminate when the speed is under 12 mph (20

km/h) and faster, the warning light will
blink and warning chime will sound for
approximately 100 seconds.
WARNING
Riding in an improper position
adversely affects the front passenger’s
seat belt warning system. It is important
for the driver to instruct the passenger
to properly be seated as instructed in this manual.
Information
• Although the front passenger seat is not occupied, the seat belt warning light
will blink or illuminate for 6 seconds.
• The front passenger’s seat belt warning may operate when luggage is placed on
the front passenger seat.

Warning and Indicator Lights
Information
Make sure that all warning lights are OFF
after starting the vehicle. If any light is still ON, this indicates a situation that needs attention.
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.
- Blinking : Emergency driving.
When the ready indicator goes OFF
or blinks, there is a problem with the
system. In this case, have your vehicle
inspected by an authorized HYUNDAI
dealer.
Service warning light
This warning light illuminates:
• When the START/STOP button is in the ON position.
- It illuminates for approximately 3 seconds and then goes off.
• When there is a problem with related

by an authorized HYUNDAI dealer.

Instrument Cluster
4-12
Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking system. This means you
still have braking on two wheels even if
one of the dual systems should fail.
With only one of the dual systems
working, more than normal pedal travel
and greater pedal pressure is required to
stop the vehicle.
Also, the vehicle will not stop in as short
a distance with only a portion of the
brake system working.
If the brakes fail while you are driving,
shift to a lower gear for additional vehicle
braking and stop the vehicle as soon as it
is safe to do so.
WARNING
Parking Brake & Brake Fluid warning
light
Driving the vehicle with a warning light
ON is dangerous. If the Parking Brake
& Brake Fluid warning light illuminates
with the parking brake released, it
indicates that the brake fluid level is
low.
If this occurs, have the vehicle
inspected by an authorized HYUNDAI
dealer. Anti-lock Brake System (ABS)
warning light
This warning light illuminates:
•
When you set the Start/Stop button to the ON position.
- The ABS warning light illuminates for about 3 seconds and then goes
off.
• Whenever there is a malfunction with the ABS.
Note that the hydraulic braking
system will still be operational even if
there is a malfunction with the ABS.
If this occurs, have the vehicle
inspected by an authorized HYUNDAI
dealer.
Electronic Brake Force
Distribution (EBD) system
warning light
When the ABS warning and
Parking Brake warning lights are on
simultaneously, it may indicate a
problem with the Electronic Brake Force
Distribution system.
If this occurs, have the vehicle inspected
by an authorized HYUNDAI dealer.
