3. Pull the shoulder portion of the seat belt all the way out. When the
shoulder portion of the seat belt
is fully extended, it will shift the
retractor to the “Automatic Locking”
(child restraint) mode.
OLF034075
4. Slowly allow the shoulder portion of
the seat belt to retract and listen for
an audible “clicking” or “ratcheting”
sound. This indicates that the retractor
is in the “Automatic Locking” mode.
If no distinct sound is heard, repeat
steps 3 and 4. 5. Remove as much slack from the belt
as possible by pushing down on the
child restraint system while feeding
the shoulder belt back into the
retractor.
6. Push and pull on the child restraint system to confirm that the seat belt
is holding it firmly in place. If it is not,
release the seat belt and repeat steps
2 through 6.
7. Double check that the retractor is in
the “Automatic Locking” mode by
attempting to pull more of the seat
belt out of the retractor. If you cannot,
the retractor is in the “Automatic
Locking” mode.
If your CRS (child restraint system)
manufacturer instructs or recommends
you to use a tether anchor with the lap/
shoulder belt, refer to the previous pages
for more information.
Information
When the seat belt is allowed to retract to
its fully stowed position, the retractor will
automatically switch from the “Automatic Locking” mode to the emergency lock
mode for normal adult usage.
WARNING
If the retractor is not in the “Automatic
Locking” mode, the child restraint
can move when your vehicle turns or
stops suddenly. A child can be seriously
injured or killed if the child restraint
is not properly anchored in the car,
including manually pulling the seat belt
all the way out to shift the rectractor to
the “Automatic Locking” mode.
To remove the child restraint, press the
release button on the buckle and then
pull the lap/shoulder belt out of the
restraint and allow the seat belt to retract
fully.

Seats & Safety System
3-38
This vehicle is equipped with an Advanced 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 and child restraints - 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 or booster seat in the front passenger seat.
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 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.

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.
„„Driver’s front air bag
ODN8039034
„„Driver’s knee air bag
ODN8039035
„„Passenger’s front air bag
ODN8039036
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.

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, 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. Side air bags
ODN8039040
ODN8039041
Your vehicle is equipped with a side air
bag in each front seat and outboard rear
seats. 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.

03
3-41
WARNING
To reduce the risk of serious injury or
death from an inflating side 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 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 put any objects between the
side airbag label and seat cushion. It
could cause harm if the vehicle is in a
crash severe enough to cause the air
bags to deploy.
• Do not cause impact to the doors
when the ignition switch button is in
the ON position as this may cause the
side air bags to inflate.
• If the seat or seat cover is damaged,
have the vehicle checked and
repaired by an authorized HYUNDAI
dealer. Curtain air bags
ODN8039042
ODN8039043
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.
The side and curtain air bags 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.

Seats & Safety System
3-42
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 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?
ODN8039033
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 (front)
4. Curtain air bag modules
5. Retractor pre-tensioner assemblies
6. Air bag warning light
7. SRS control module (SRSCM) /
Rollover sensor
8. Front impact sensors
9. Side impact sensors (acceleration)
10. Side impact sensors (pressure)
11. Driver’s knee air bag module
12. Occupant classification system
13. Side air bag modules (rear)
The SRSCM (Supplemental Restraint
System Control Module) continually
monitors all SRS components while the
Engine Start/Stop button is in the ON or
START position to determine if a crash
impact is severe enough to require air
bag deployment or pre-tensioner seat
belt deployment.

3-43
SRS warning light
The SRS (Supplement 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 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 six seconds when the
Engine Start/Stop button is in the ON position.
• The light stays on after illuminating
for approximately 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. During a frontal collision, sensors will
detect the vehicle’s deceleration. If the
rate of deceleration is high enough, the
control unit will inflate the front air bags.
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. •
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.
• Generally, air bags are designed to
inflate based upon the severity of
a collision, its direction, etc. 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.
