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.

01
1-9
•
Natural degradation may occur with
the high voltage battery depending
on the number of years the vehicle is
used. This may reduce the distance to
empty.
• When the charge capacity and
distance to empty keep falling,
contact an authorized HYUNDAI
dealer for inspection and
maintenance.
• If the vehicle will not be in use for an
extended period of time, charge the
high voltage battery once every three
months to prevent it from discharging.
Also, if the charge amount is not
enough, immediately charge to full
and store the vehicle.
• AC charge is recommended to keep
the high voltage battery in optimal condition.
If the high voltage battery charge
amount is below 20%, you can keep
the high voltage battery performance
in optimal condition if you charge the
high voltage battery to 100%. (Once a
month or more is recommended.)
The value of the high voltage battery
charge level may vary according to
the charging conditions (state of
charger, outside temperature, battery
temperature, etc.). In order to fully
charge the battery, the current of the
high voltage battery will be gradually
decreased, so that the longevity and
safety of the battery can be secured.
CAUTION
• If the vehicle is kept with insufficient
charge for a long period, it may
damage the high voltage battery and
the high voltage battery may have to
be replaced depending on the level
of degradation.
• If the vehicle is in a collision, contact
an authorized HYUNDAI dealer to
inspect whether the high voltage
battery is still connected.
• Using the V2L function may reduce
the mileage due to the use of high
voltage battery energy, and repeated
use of the V2L function may cause
a decrease in the life of the high
voltage battery.
High Voltage Battery Warmer
System
The high voltage battery warmer system
prevents reduction of battery output
when battery temperature is low. If the
charging connector is connected, the
warmer system automatically operates
according to the battery temperature.
Charging time may shorten compare to
vehicles without the high voltage battery
warmer system. But, electricity charge
may increase because of high voltage
battery warmer system operation.
CAUTION
The high voltage battery warmer
system operates when the charging
connector is connected to the vehicle.
However, the high voltage warmer
system may not operate when battery
temperature drops below -31°F (-35°C).

Seats & Safety System
3-2
You will find many safety precautions
and recommendations throughout this
section, and throughout this manual.
The safety precautions in this section are
among the most important.
Always Wear Your Seat Belt
A seat belt is your best protection in all
types of accidents. Air bags are designed
to supplement seat belts, not to replace
them. So even though your vehicle is
equipped with air bags, ALWAYS make
sure you and your passengers wear your
seat belts, and wear them properly.
Restrain All Children
All children under age 13 should ride
in your vehicle properly restrained in a
rear seat, not the front seat. Infants and
small children should be restrained in
an appropriate Child Restraint System.
Larger children should use a booster
seat with the lap/shoulder belt until they
can use the seat belt properly without a
booster seat.
Air Bag Hazards
While air bags can save lives, they can
also cause serious or fatal injuries to
occupants who sit too close to them, or
who are not properly restrained. Infants,
young children, and short adults are at
the greatest risk of being injured by an
inflating air bag. Follow all instructions
and warnings in this manual.
Driver Distraction
Driver distraction presents a serious and
potentially deadly danger, especially for
inexperienced drivers. Safety should be
the first concern when behind the wheel
and drivers need to be aware of the wide
array of potential distractions, such as
drowsiness, reaching for objects, eating,
personal grooming, other passengers, and using mobile phones.
Drivers can become distracted when
they take their eyes and attention off
the road or their hands off the wheel to
focus on activities other than driving.
To reduce your risk of distraction and an
accident: •
Set up your mobile devices (for
example, MP3 players, phones,
navigation units, etc.) ONLY when
your vehicle is parked or safely
stopped.
• ONLY use your mobile device when
allowed by laws and conditions permit
safe use. NEVER text or email while
driving. Most countries have laws
prohibiting drivers from texting. Some
countries and cities also prohibit
drivers from using handheld phones.
• NEVER let the use of a mobile device
distract you from driving. You have a
responsibility to your passengers and
others on the road to always drive
safely, with your hands on the wheel
as well as your eyes and attention on
the road.
Control Your Speed
Excessive speed is a major factor in crash
injuries and deaths. Generally, the higher
the speed, the greater the risk, but
serious injuries can also occur at lower
speeds. Never drive faster than is safe
for current conditions, regardless of the
maximum speed posted.
Keep Your Vehicle In Safe Condition
Having a tire blowout or a mechanical
failure can be extremely hazardous. To
reduce the possibility of such problems,
check your tire pressures and condition
frequently, and perform all regularly
scheduled maintenance.
Important safety precautIons

Do not install a Child Restraint
System on the Front Passenger’s
Seat
OHI039193N
Even though your vehicle is equipped
with the OCS, never install a child
restraint in the front passenger’s seat.
An inflating air bag can forcefully strike a
child or child restraint resulting in serious
or fatal injury.
WARNING
NEVER use a rearward facing Child
Restraint on a seat protected by an
ACTIVE AIRBAG in front of it, DEATH
or SERIOUS INJURY to the CHILD can
occur.
Why didn’t my air bag go off in a
collision?
There are certain types of accidents in
which the air bag would not be expected
to provide additional protection. These
include rear impacts, second or third
collisions in multiple impact accidents,
as well as low speed impacts. Damage to
the vehicle indicates a collision energy
absorption, and is not an indicator of
whether or not an air bag should have
inflated. Air bag collision sensors
WARNING
To reduce the risk of an air bag
deploying unexpectedly and causing
serious injury or death: • Do not hit or allow any objects to
impact the locations where air bags
or sensors are installed.
• Do not perform maintenance on or
around the air bag sensors. If the
location or angle of the sensors is
altered, the air bags may deploy
when they should not or may not
deploy when they should.
• Installing bumper guards with non-
genuine Hyundai or non-equivalent
parts may adversely affect the
collision and airbag deployment
performance.
To ensure correct function of the
airbag system, have the bumper
replaced with genuine Hyundai part
or the equivalent (of the genuine
part) specified for your vehicle.
• Press the Start/Stop button to the
OFF or ACC position and wait for 3
minutes when the vehicle is being
towed to prevent inadvertent air bag
deployment.
• Have all air bag repairs conducted by
an authorized HYUNDAI dealer.

SRS Care
The SRS is virtually maintenance-free
and there are no parts you can safely
service by yourself. If the SRS air bag
warning light does not illuminate
when the Start/Stop button is in the
ON position, or continuously remains
on, have the system be immediately
inspected by an authorized HYUNDAI
dealer.
We recommend any work on the SRS
system, such as removing, installing,
repairing, or any work on the steering
wheel, the front passenger’s panel, front
seats and roof rails be performed by an
authorized HYUNDAI dealer. Improper
handling of the SRS system may result in
serious personal injury. WARNING
To reduce the risk of serious injury or
death take the following precautions: • Do not attempt to modify or
disconnect the SRS components or
wiring, including the addition of any
kind of badges to the pad covers or
modifications to the body structure.
• Do not place objects over or near
the air bag modules on the steering
wheel, instrument panel, and the
front passenger’s panel above the
glove box.
• Clean the air bag pad covers with
a soft cloth moistened with plain
water. Solvents or cleaners could
adversely affect the air bag covers
and proper deployment of the
system.
• Have the inflated air bags be
replaced by an authorized HYUNDAI
dealer.
• If components of the air bag system
must be discarded, or if the vehicle
must be scrapped, certain safety
precautions must be observed.
Consult an authorized HYUNDAI
dealer for the necessary information.
Failure to follow these precautions
could increase the risk of personal
injury.
