Rear Occupant Alert is provided to
prevent a driver from leaving a vehicle
with a rear passenger left in the vehicle.
System setting
To use Rear Occupant Alert, it must be
enabled from the Settings menu in the
infotainment system screen. Select:
-Setup → Vehicle Settings → Convenience → Rear Occupant Alert
For detailed information, scan the QR
code in the separately supplied simple
manual.
System operation
• First alert
When you turn off the engine and
open the driver’s door after opening
and closing the rear door or liftgate,
the ‘Check rear seats’ warning
message appears on the cluster.
• Second alert
After the first alert, the second alert
operates when any movement is
detected in the vehicle after the
driver’s door is closed and all the
doors are locked. The horn will sound
for approximately 25 seconds. If
the system continues to detect a
movement, the alert operates up to 8
times.
Unlock the doors with the smart key
to stop the alert.
• The system detects movement in the
vehicle for 8 hours after the door is
locked.
• The second alert is activated only after
the prior activation of the first alert.
System precautions
• Make sure that all the windows are
closed. If the window is open, the
alert may operate by the sensor
detecting an unintended movement
(e.g. wind or bugs).

NOTICE
The sensor that activates the SRS
control module is connected with the
pre–tensioner seat belts. The SRS air
bag warning light on the instrument
cluster will illuminate for approximately
3~6 seconds after the Engine Start/Stop
button is in the ON position, and then it
should turn off.
If the pre-tensioner is not working
properly, the warning light will
illuminate even if the SRS air bag is not
malfunctioning. If the warning light
does not illuminate, stays illuminated
or illuminates when the vehicle is
being driven, we recommend the pre-
tensioner seat belts and/or SRS control
module be inspected by an authorized
HYUNDAI dealer as soon as possible.
Information
• Pre-tensioner seat belts may be
activated in certain frontal or side
collisions or rollover situations (if
equipped with rollover sensor).
• When the pre-tensioner seat belts are
activated, a loud noise may be heard
and fine dust, which may appear to be
smoke, may be visible in the passenger
compartment. These are normal
operating conditions and are not
hazardous.
• Although it is non-toxic, the fine dust
may cause skin irritation and should
not be inhaled for prolonged periods.
Wash all exposed skin areas thoroughly
after an accident in which the pre-
tensioner seat belts were activated.
Additional seat belt safety
precautions
Seat belt use during pregnancy
The seat belt should always be used
during pregnancy. The best way to
protect your unborn child is to protect
yourself by always wearing the seat belt.
Pregnant women should always wear
a lap-shoulder seat belt. Place the
shoulder belt across your chest, routed
between your breasts and away from
your neck. Place the lap belt below your
belly so that it fits SNUGLY across your
hips and pelvic bone, under the rounded
part of the belly.
WARNING
To reduce the risk of serious injury or
death to an unborn child during an
accident, pregnant women should
NEVER place the lap portion of the
seat belt above or over the area of the
abdomen where the unborn child is
located.
Seat belt use and children
Infant and small children
Most countries have Child Restraint
System laws which require children to
travel in approved Child Restraint System
devices, including booster seats. The age
at which seat belts can be used instead
of Child Restraint System differs among
countries, so you should be aware of the
specific requirements in your country,
and where you are travelling. Infant and
Child Restraint System must be properly
placed and installed in a rear seat.
For more information refer to the “Child
Restraint Systems” section in this
chapter.

Where are the air bags?
Driver’s and passenger’s front air
bags
„„Driver’s front air bag
OCN7030036
„„Passenger’s front air bag
ONX4030037
Your vehicle is equipped with a
Supplemental Restraint System (SRS)
and lap/shoulder belts at both the driver
and passenger seating positions.
The SRS consists of air bags which are
located in the center of the steering
wheel and the passenger’s side front
panel pad above the glove box.
The air bags are labeled with the letters
“AIR BAG” embossed on the pad covers.
The purpose of the SRS is to provide the
vehicle’s driver and front passengers with
additional protection than that offered
by the seat belt system alone in case of a
frontal impact of sufficient severity.
The SRS uses sensors to gather
information about the driver’s and front
passenger's seat belt usage and impact
severity.The seat belt buckle sensors determine
if the driver and front passenger's seat
belts are fastened. These sensors provide
the ability to control the SRS deployment
based on whether or not the seat belts are
fastened, and how severe the impact is.
The advanced SRS offers the ability to
control the air bag inflation within two
levels. A first stage level is provided for
moderate-severity impacts. A second
stage level is provided for more severe
impacts.
According to the impact severity, and
seat belt usage, the SRS Control Module
(SRSCM) controls the air bag inflation.
Failure to properly wear seat belts can
increase the risk or severity of injury in an
accident.
WARNING
To reduce the risk of serious injury or
death from inflating front air bags, take
the following precautions:
•
Seat belts must be worn at all times
to help keep occupants positioned
properly.
• Move your seat as far back as
possible from front air bags, while
still maintaining control of the
vehicle.
• Never lean against the door or center
console.
• Do not allow the front passenger
to place their feet or legs on the
dashboard.
• No objects (such as crash pad
cover, mobile phone holder, cup
holder, perfume or stickers) should
be placed over or near the air bag
modules on the steering wheel,
instrument panel, windshield glass,
and the front passenger’s panel
above the glove box. Such objects
could cause harm if the vehicle is in a
crash severe enough to cause the air
bags to deploy.
• Do not attach any objects on the
front windshield and inside mirror.

Side air bags
„„Side air bag
ONX4030039
OTM030030
Your vehicle is equipped with a side air
bag in each front seat. The purpose of
the air bag is to provide the vehicle’s
driver and the front passenger with
additional protection than that offered by
the seat belt alone.
The side air bags are designed to deploy
during certain side impact collisions,
depending on the crash severity, angle,
speed and point of impact.
The side air bags on both sides of the
vehicle are designed to deploy when a
rollover is detected by a rollover sensor.
(if equipped with rollover sensor)
The side air bags are not designed to
deploy in all side impact or rollover
situations.
WARNING
To reduce the risk of serious injury or
death from an inflating side air bag and
front center air bag, take the following
precautions:
• Seat belts must be worn at all times
to help keep occupants positioned
properly.
• Do not allow passengers to lean their
heads or bodies onto doors, put their
arms on the doors, stretch their arms
out of the window, or place objects
between the doors and seats.
• Hold the steering wheel at the 9
o’clock and 3 o’clock positions, to
minimize the risk of injuries to your
hands and arms.
• Do not use any accessory seat
covers. This could reduce or prevent
the effectiveness of the system.
• Do not hang other objects except
clothes. In an accident it may cause
vehicle damage or personal injury
especially when air bag is inflated.
• Do not place any objects over the
air bag or between the air bag and
yourself. Also, do not attach any
objects around the area the air bag
inflates such as the door, side door
glass, front and rear pillar.
• Do not place any objects between
the door and the seat. They may
become dangerous projectiles if the
side air bag inflates.
• Do not install any accessories on the
side or near the side air bags.
• Do not cause impact to the doors
when the Engine Start/Stop button
is in the ON or START position as this
may cause the side air bags to inflate.
• If the seat or seat cover is damaged,
we recommend that the system be
serviced by an authorized HYUNDAI
dealer.

Curtain air bags
ONX4030040
OTM030032
Curtain air bags are located along both
sides of the roof rails above the front and
rear doors.
They are designed to help protect the
heads of the front seat occupants and
the rear outboard seat occupants in
certain side impact collisions.
The curtain air bags are designed to
deploy during certain side impact
collisions, depending on the crash
severity, angle, speed and impact.For vehicles equipped with a rollover
sensor the side and/or curtain air bags
and pre-tensioners on both sides of
the vehicle may deploy if a rollover or
possible rollover is detected.
The curtain air bags are not designed
to deploy in all side impact or rollover
situations.
WARNING
To reduce the risk of serious injury or
death from an inflating curtain air bag,
take the following precautions:
•
All seat occupants must wear
seat belts at all times to help keep
occupants positioned properly.
• Properly secure Child Restraint
System as far away from the door as
possible.
• Do not place any objects over the air
bag. Also, do not attach any objects
around the area the air bag inflates
such as the door, side door glass,
front and rear pillar, roof side rail.
• Do not hang other objects except
clothes, especially hard or breakable
objects.
In an accident, it may cause vehicle
damage or personal injury.
• Do not allow passengers to lean their
heads or bodies onto doors, put their
arms on the doors, stretch their arms
out of the window, or place objects
between the doors and seats.
• Do not open or repair the side curtain
air bags.

How does the air bags system
operate?
ONX4030055
The SRS consists of the following
components:
(1) Driver's front air bag module
(2) Passenger's front air bag module
(3) Side air bag modules
(4) Curtain air bag modules
(5) Retractor pre-tensioner
(6) Air bag warning light
(7) SRS control module (SRSCM)/
Rollover sensor
(8) Front impact sensors
(9) Side impact sensors
(10) Side pressure sensors
(11) Emergency fastening device system
(12) Occupant classification system
(13) Seat belt buckle sensor
The SRSCM continually monitors all SRS
components while the ignition switch
is ON to determine if a crash impact
is severe enough to require air bag
deployment or pre-tensioner seat belt
deployment.
SRS warning light
The SRS (Supplemental Restraint System)
air bag warning light on the instrument
panel displays the air bag symbol
depicted in the illustration. The system
checks the air bag electrical system for
malfunctions. The light indicates that
there is a potential problem with your
air bag system, which could include
your side and/or curtain air bags used
for rollover protection (if equipped with
rollover sensor).
WARNING
If your SRS malfunctions, the air bag
may not inflate properly during an
accident increasing the risk of serious
injury or death.
If any of the following conditions occur,
your SRS is malfunctioning:
• The light does not turn on for
approximately three to six seconds
when the Engine Start/Stop button is
in the ON position.
• The light stays on after illuminating
for approximately three to six
seconds.
• The light comes on while the vehicle
is in motion.
• The light blinks when the engine is
running.
We recommend that an authorized
HYUNDAI dealer inspect the SRS
as soon as possible if any of these
conditions occur.

Seats & Safety System

During a moderate to severe frontal
collision, sensors will detect the
vehicle’s rapid deceleration. If the rate of
deceleration is high enough, the control
unit will inflate the front air bags, at the
time and with the force needed.
The front air bags help protect the driver
and front passenger by responding to
frontal impacts in which seat belts alone
cannot provide adequate restraint. When
needed, the side air bags help provide
protection in the event of a side impact
or rollover by supporting the side upper
body area.
• Air bags are activated (able to
inflate if necessary) only when the
Engine Start/Stop button is in the
ON or START position, and it can be
activated within about 3 minutes after
the engine is turned off.
• Air bags inflate in the event of certain
frontal or side collisions to help
protect the occupants from serious
physical injury.
• There is no single speed at which the
air bags will inflate. Generally, air bags
are designed to inflate based upon the
severity of a collision and its direction.
These two factors determine whether
the sensors produce an electronic
deployment/inflation signal.
• The front air bags will completely
inflate and deflate in an instant. It is
virtually impossible for you to see the
air bags inflate during an accident. It is
much more likely that you will simply
see the deflated air bags hanging out
of their storage compartments after
the collision. •
In addition to inflating in serious side
collisions, vehicles equipped with a
rollover sensor, side and/or curtain air
bags will inflate if the sensing system
detects a rollover.
When a rollover is detected, curtain
air bags will remain inflated longer to
help provide protection from ejection,
especially when used in conjunction
with the seat belts. (if equipped with a
rollover sensor)
• To help provide protection, the air
bags must inflate rapidly. The speed
of air bag inflation is a consequence
of extremely short time in which
to inflate the air bag between the
occupant and the vehicle structures
before the occupant impacts those
structures. This speed of inflation
reduces the risk of serious or
lifethreatening injuries and is thus a
necessary part of air bag design.
However, the rapid air bag inflation
can also cause injuries which can
include facial abrasions, bruises and
broken bones because the inflation
speed also causes the air bags to
expand with a great deal of force.
• There are even circumstances under
which contact with the air bag can
cause fatal injuries, especially if the
occupant is positioned excessively
close to the air bag.
You can take steps to reduce the risk
of being injured by an inflating air bag.
The greatest risk is sitting too close to
the air bag. An air bag needs about 10
in. (25 cm) of space to inflate. NHTSA
recommends that drivers allow at least
10 in. (25 cm) between the center of the
steering wheel and the chest.

Main components of the Occupant
Classification System
• A detection device located within the
front passenger seat cushion.
• Electronic system to determine
whether the passenger air bag
systems should be activated or
deactivated.
• An indicator light located on the
instrument panel which illuminates
the words “PASSENGER AIR BAG OFF”
indicating the front passenger air bag
system is deactivated.
• The instrument panel air bag indicator
light is interconnected with the OCS.
The OCS is designed to help detect
the presence of a properly-seated
front passenger and determine if the
passenger’s front air bag should be
enabled (may inflate) or not.
The purpose is to help reduce the risk
of injury or death from an inflating air
bag to certain front passenger seat
occupants, such as children, by requiring
the air bag to be automatically turned
OFF.
For example, if a child restraint of the
type specified in the regulations is on the
seat, the occupant classification sensor
can detect it and cause the air bag to
turn OFF.
Front passenger seat adult occupants
who are properly seated and wearing the
seat belt properly, should not cause the
passenger air bag to be automatically
turned OFF. For smaller adults it may turn
OFF, however, if the occupant does not
sit in the seat properly (for example, by
not sitting upright, by sitting on the edge
of the seat, or by otherwise being out of
position), this could cause the sensor to
turn the air bag OFF. You will find the “PASSENGER AIR BAG
OFF” indicator on the overhead console
panel. This system detects the conditions
1-4 in the following table and activates or
deactivates the front passenger air bag
based on these conditions.
Always be sure that you and all vehicle
occupants are seated properly and
wearing the seat belt properly for the
most effective protection by the air bag
and the seat belt.
The OCS may not function properly if the
passenger takes actions which can affect
the classification system. These include:
•
Failing to sit in an upright position.
• Leaning against the door or center
console.
• Sitting towards the sides of the front
of the seat.
• Putting their legs on the dashboard or
resting them on other locations which
reduce the passenger weight on the
front seat.
• Wearing the seat belt improperly.
• Reclining the seatback.
• Wearing thick clothes like ski wear or
hip protection wear.
• Putting an additional thick cushion on
the seat.
• Putting electrical devices (e.g.
notebook, satellite radio) on the seat
with inverter charging.
