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.
This must be done 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-
tensioners become hot and can burn
you.
OHI038175LOHI038175L
The Pre-Tensioner Seat Belt System
consists mainly of the following
components. Their locations are shown
in the illustration above:
1. SRS air bag warning light
2. Retractor pre-tensioner (front)
3. SRS control module
NOTICE
The sensor that activates the SRS air
bag is connected with the pre-tensioner
seat belts. The SRS air bag warning light
on the instrument panel will illuminate
for approximately 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, have an authorized HYUNDAI
dealer inspect the pre-tensioner seat
belts and SRS air bags as soon as
possible.

Where Are the Air Bags?
Driver’s and passenger’s front air
bags
Your vehicle is equipped with an
Advanced 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, in the driver’s side lower crash
pad below the steering wheel column
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.

OCN7030038OCN7030038
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. 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.

Seats & Safety System3-34
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,
cellular phone holder, cup holder,
air fresheners 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
Front seatFront seat
OCN7N031041NOCN7N031041N
OCN7N031042NOCN7N031042N
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
only during certain side impact collisions,
depending on the crash severity. The
side and curtain air bags on both sides
of the vehicle may deploy if a rollover or
possible rollover is detected. For vehicles
equipped with a rollover sensor the side
air bags and pre-tensioners on both sides
of the vehicle may deploy if a rollover or
possible rollover is detected. However,
the side air bags are not designed to
deploy in all side impact or rollover
situations.

Seats & Safety System3-36
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 restraints as far
away from the door as possible.
• Do not hang or 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 Bag System
Operate?
OCN7N031141OCN7N031141
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 assemblies
(6) Air bag warning light
(7) SRS control module (SRSCM)
(8) Front impact sensors
(9) Side impact sensors (acceleration)
(10) Side impact sensors (pressure)
(11) Occupant classification system
(12) Driver’s and front passenger’s seat
belt buckle sensors
The SRSCM (Supplemental Restraint
System Control Module) continually
monitors all SRS components while
the Engine Start/Stop button is in the
ON position or approximately within
3 minutes after the ignition is off 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 (Supplement Restraint System)
air bag w
arning 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 malfunction with your
air bag system, which could include your
side and curtain air bags used for rollover
protection.
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.
Have an authorized HYUNDAI dealer
inspect the SRS as soon as possible if
any of these conditions occur. 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) when the Engine Start/
Stop button is in the ON position or
approximately within 3 minutes after
ignition 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 certain side collisions, vehicles equipped with a
rollover sensor, side and curtain air
bags will inflate if the sensing system
detects a rollover.
When a rollover is detected, side and
curtain air bags will remain inflated
longer to help provide protection
from ejection, especially when used in
conjunction with the seat belts.

Occupant Classification System
(OCS)
OCN7N031139NOCN7N031139N
OCN7030070NOCN7030070N
Your vehicle is equipped with an
Occupant Classification System (OCS) in
the front passenger’s seat.
Main components of the Occupant
Classification System
• A detection device located within the front passenger seat cushion.
• Electronic system to help 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.
CN7 N HMA 3.indd 3-41 2021-09-06  2:24:35

Seats & Safety System3-42
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 small adults it may be
turned 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.
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.
Never install a Child Restraint System in
the front passenger’s seat. If you should
install a CRS (Child Restraint System)
inevitably, use a forward-facing CRS with
3-point ALR safety seat belt and adjust
the front passenger’s seat as far to the
rear as possible. If the PASSENGER AIR
BAG “OFF” indicator is OFF after a CRS
(Child Restraint System) is equipped,
the front passenger’s airbag is operating
so you should install the CRS in the rear
seats of the vehicle immediately. 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 a thick cloth like ski wear or hip protection wear.
• Putting an additional thick cushion on the seat.
• Putting electrical devices (for example, notebook, satellite radio) on
the seat with inverter charging.

• Do not place electronic devices such as laptops, DVD
player, or conductive materials such as water bottles
on the passenger seat.
• Do not use electronic devices such as laptops and
satellite radios which use inverter chargers.
OHI038162OHI038162
• If large amount of liquid has been spilled on the
passenger seat, the air bag warning light may
illuminate or malfunction.
Therefore, make sure the seat has been completely
dried before driving the vehicle.
• Do not place sharp objects on the front passenger seat. These may damage the
occupant detection system, if they puncture the seat cushion.
• Do not place any items under the front passenger seat.
• When changing or replacing the seat or seat cover, use original items only.
The OCS has been developed based on using original HYUNDAI car seats only.
Altering or changing the authentic parts may result in system malfunction and
increase risk of injury when in collision. Any of the above could interfere with the
proper operation of the OCS sensor thereby increasing the risk of an injury in an
accident.
