•
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.

seat belts
This section describes how to use the
seat belts properly. It also describes
some of the things not to do when using
seat belts.
Seat Belt Safety Precautions
Always fasten your seat belt and make
sure all passengers have fastened their
seat belts before starting any trip. Air
bags are designed to supplement the
seat belt as an additional safety device,
not a replacement. Most countries
require all occupants of a vehicle to wear
seat belts.
WARNING
Seat belts must be used by ALL
passengers whenever the vehicle is
moving. Take the following precautions
when adjusting and wearing seat belts: • Children under the age of 13 should
be properly restrained in the rear
seats.
• Never allow children to ride in the
front passenger seat, unless the air
bag is deactivated. If a child is seated
in the front passenger seat, move
the seat as far back as possible and
properly restrain them in the seat.
• NEVER allow an infant or child to be
carried on an occupant’s lap.
• NEVER ride with the seatback
reclined when the vehicle is moving.
• Do not allow children to share a seat
or seat belt.
• Do not wear the shoulder belt under
your arm or behind your back. •
NEVER wear a seat belt over fragile
objects. If there is a sudden stop or
impact, the seat belt can damage it.
• Do not use the seat belt if it is
twisted. A twisted seat belt will not
protect you properly in an accident.
• Do not use a seat belt if the webbing
or hardware is damaged.
• Do not latch the seat belt into the
buckles of other seats.
• NEVER unfasten the seat belt
while driving. This may cause loss
of vehicle control resulting in an
accident.
• Make sure there is nothing in the
buckle interfering with the seat belt
latch mechanism. This may prevent
the seat belt from fastening securely.
• No modifications or additions
should be made by the user which
will either prohibit the seat belt
adjusting devices from operating to
remove slack, or prohibit the seat
belt assembly from being adjusted to
remove slack.
WARNING
Damaged seat belts and seat belt
assemblies will not operate properly.
Always replace: • Frayed, contaminated, or damaged
webbing.
• Damaged hardware.
• The entire seat belt assembly after it
has been worn in an accident, even
if damage to webbing or assembly is
not apparent.

(1) Retractor Pretensioner
The purpose of the retractor pre-
tensioner is to make sure that the
shoulder belts fit in tightly against the
occupant’s upper body in certain frontal
or side collision(s).
If the system senses excessive tension
on the driver or passenger’s seat belt
when the pre-tensioner system activates,
the load limiter inside the retractor
pre-tensioner will release some of the
pressure on the affected seat belt.
WARNING
• Always wear your seat belt and sit
properly in your seat.
• Do not use the seat belt if it is loose
or twisted. A loose or twisted seat
belt will not protect you properly in
an accident.
• Do not place anything near the
buckle. This may adversely affect
the buckle and cause it to function
improperly.
• Always replace your pre-tensioners
after activation or an accident.
• NEVER inspect, service, repair or
replace the pre-tensioners yourself.
Have the pre-tensioners inspected,
serviced, repaired or replaced by an
authorized HYUNDAI dealer.
• Do not hit the seat belt assemblies.
WARNING
Do not touch the pre-tensioner seat
belt assemblies for several minutes
after they have been activated. When
the pre-tensioner seat belt mechanism
deploys during a collision, the pre-
tensioner can become hot and can burn
you.
CAUTION
Body work on the front area of the
vehicle may damage the pre-tensioner
seat belt system. Therefore, have the
system serviced by an authorized
HYUNDAI dealer.

Seats & Safety System
3-38
Care of Seat Belts
Seat belt systems should never be disassembled or modified. In addition,
care should be taken to assure that seat
belts and belt hardware are not damaged
by seat hinges, doors or other abuse.
Periodic inspection
All seat belts should be inspected
periodically for wear or damage of any
kind. Any damaged parts should be
replaced as soon as possible.
Keep belts clean and dry
Seat belts should be kept clean and
dry. If belts become dirty, they can be
cleaned by using a mild soap solution
and warm water. Bleach, dye, strong
detergents or abrasives should not be
used because they may damage and
weaken the fabric.
When to replace seat belts
The entire seat belt assembly or
assemblies should be replaced if the
vehicle has been involved in an accident.
This should be done even if no damage is
visible. Consult an authorized HYUNDAI
dealer.

Seats & Safety System

The vehicles are equipped with a Supplemental Air Bag System for the driver’s seat and
front passenger’s seats.
The front air bags are designed to supplement the three-point seat belts. For these air
bags to provide protection, the seat belts must be worn at all times when driving.
You can be severely injured or killed in an accident if you are not wearing a seat belt.
Air bags are designed to supplement seat belts, but do not replace them. Also, air bags
are not designed to deploy in every collision. In some accidents, the seat belts are the
only restraint protecting you.
WARNING
AIR BAG SAFETY PRECAUTIONS
ALWAYS use seat belts Child Restraint Systems - every trip, every time, everyone!
Even with air bags, you can be seriously injured or killed in a collision if you are
improperly belted or not wearing your seat belt when the air bag inflates.
NEVER place a child in any Child Restraint System or booster seat in the front
passenger seat, unless the air bag is deactivated.
An inflating air bag could forcefully strike the infant or child causing serious or fatal injuries.
ABC - Always Buckle Children under age 13 in the back seat. It is the safest place
for children of any age to ride. If a child age 13 or older must be seated in the front
seat, he or she must be properly belted and the seat should be moved as far back as possible.
All occupants should sit upright with the seatback in an upright position, centered
on the seat cushion with their seat belt on, legs comfortably extended and their feet
on the floor until the vehicle is parked and the vehicle is turned off. If an occupant
is out of position during an accident, the rapidly deploying air bag may forcefully
contact the occupant causing serious or fatal injuries.
You and your passengers should never sit or lean unnecessarily close to the air bags
or lean against the door or center console.
Move your seat as far back as possible from front air bags, while still maintaining
control of the vehicle. The U.S. National Highway Traffic Safety Administration
(NHTSA) recommends that drivers allow at least 10 inches (25 cm) between the
center of the steering wheel and the chest.

What to Expect After an Air Bag
Inflates
After a frontal or side air bag inflates, it
will deflate very quickly. Air bag inflation
will not prevent the driver from seeing
out of the windshield or being able
to steer. Curtain air bags may remain
partially inflated for some time after they
deploy.
WARNING
After an air bag inflates, take the
following precautions: • Open your windows and doors as
soon as possible after impact to
reduce prolonged exposure to the
smoke and powder released by the
inflating air bag.
• Do not touch the air bag storage
area’s internal components
immediately after an air bag has
inflated. The parts that come into
contact with an inflating air bag may
be very hot.
• Always wash exposed skin areas
thoroughly with cold water and mild soap.
• Have an authorized HYUNDAI dealer
replaced the air bag immediately
after deployment. Air bags are
designed to be used only once. Noise and smoke from inflating air bag
When the air bags inflate, they make a
loud noise and may produce smoke and
powder in the air inside of the vehicle.
This is normal and is a result of the
ignition of the air bag inflator. After the
air bag inflates, you may feel substantial
discomfort in breathing because of the
contact of your chest with both the seat
belt and the air bag, as well as from
breathing the smoke and powder. The
powder may aggravate asthma for some
people. If you experience breathing
problems after an air bag deployment,
seek medical attention immediately.
Though the smoke and powder are
nontoxic, they may cause irritation to
the skin, eyes, nose, throat, etc. If this is
the case, wash and rinse with cold water
immediately and seek medical attention
if the symptoms persist.

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.
