The Pre-Tensioner Seat Belt System
consists mainly of the following com-
ponents. Their locations are shown in
the illustration above:
1. SRS air bag warning light
2. Retractor pre-tensioner assembly
3. SRS control module
4. Anchor pre-tensioner assembly
✽✽NOTICE
The sensor that activates the SRS air
bag is connected with the pre–ten-
sioner seat belts. The SRS air bag
warning light on the instrument panel
will illuminate for approximately 6
seconds after the ignition switch is
placed in the ON position, and then it
should turn off.
If the pre-tensioner is not working
properly, the warning light will illu-
minate 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.
Do not touch the pre-tensioner
seat belt assemblies for several
minutes after they have been
activated. When the pre-ten-
sioner seat belt mechanismfires during a collision the pre-tensioner becomes hot and can
burn you.

Where are the air bags?
Driver’s and passenger’s frontair bags
Your vehicle is equipped with a
Advanced Supplemental RestraintSystem (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 steer-ing wheel and the passenger's side
front panel pad above the glove box. The air bags are labeled with the let-
ters “AIR BAG” embossed on the pad
covers.
The purpose of the SRS is to provide
the vehicle's driver and front passen-gers with additional protection than
that offered by the seat belt system
alone. The SRS uses sensors to
gather information about the driver's
seat position, the driver's and frontpassenger's seat belt usage and
impact severity. To reduce the risk of serious
injury or death from an inflating
front air bags, take the followingprecautions:
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 passen-ger to place their feet or legs on
the dashboard.
No objects should be placed
over or near the air bag mod-ules on the steering wheel,
instrument panel, 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 impact air bags
Your vehicle is equipped with a side
impact air bag in each seat. The pur-
pose of the air bag is to provide the
vehicle's driver and the front passen-ger with additional protection than that
offered by the seat belt alone.The side impact air bags are
designed to deploy only during certain
side impact collisions, depending on
the crash severity, angle, speed andpoint of impact. The side impact air bags do not only
deploy on the side of the impact but
also on the opposite side.
For vehicles equipped with a rollover
sensor the side and curtain air bags
on both sides of the vehicle may
deploy if a rollover or possible
rollover is detected. The side impact air bags are not
designed to deploy in all side impact
or rollover situations.

To reduce the risk of serious
injury or death from an inflating
side impact air bag, take the fol-
lowing 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 effectivenessof the system.
Do not place any objects over
the air bag or between the air
bag and yourself.

Curtain air bags
Curtain air bags are located along
both sides of the roof rails above the
front and rear doors.They are designed to help protect theheads of the front seat occupantsand the rear outboard
seat occupants
in certain side impact collisions.
The curtain air bags are designed to
deploy only during certain side
impact collisions, depending on the
crash severity, angle, speed andimpact.
The curtain air bags do not only
deploy on the side of the impact but
also on the opposite side.
For vehicles equipped with a rollover
sensor 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.
(Continued)
Do not place any objects between the door and the
seat. They may become dan-
gerous projectiles if the side
impact air bag inflates.
Do not install any accessories on the side or near the side
impact air bags.
Do not cause impact to the
doors when the ignition
switch is in the ON position or
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.

How does the air bags system operate?
The SRS consists of the following components:
1. Driver's front air bag module
2. Passenger's front air bag module
3. Side impact air bag modules
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 10. “PASSENGER AIR BAG OFF”
indicator
11. Occupant classification system
12. Driver’s and front passenger’s seat belt buckle sensors
13. Anchor pre-tensioner assembly
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.
To reduce the risk of serious
injury or death from an inflating
curtain air bags, take the follow-ing precautions:
All seat occupants must wear seat belts at all times to helpkeep occupants positioned
properly.
Properly secure child restraints
as far away from the door as
possible.
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 doorsand seats.
Do not open or repair the side
curtain air bags.

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 indi-
cates that there is a potential problem
with your air bag system, which could
include your side and curtain air bags
used for rollover protection.During a moderate to severe frontal
collision, sensors will detect the vehi-
cle’s rapid deceleration. If the rate of
deceleration is high enough, the con-
trol unit will inflate the front air bags. The front air bags help protect the
driver and front passenger byresponding to frontal impacts in
which seat belts alone cannot provide
adequate restraint. When needed,
the side air bags help provide protec-
tion in the event of a side impact or
rollover by supporting the side upperbody area.
Air bags are activated (able to
inflate if necessary) only when the
ignition switch is in the ON position.
Air bags inflate in the event of a severe frontal or side collision tohelp 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 colli-
sion and its direction. These two
factors determine whether the sen-
sors produce an electronic deploy-ment/inflation signal.
If your SRS malfunctions, the
air bag may not inflate properlyduring an accident increasing
the risk of serious injury ordeath.
If any of the following condi-
tions occur, your SRS is mal-functioning:
The light does not turn on for
approximately six seconds
when the ignition switch isplaced in the ON position.
The light stays on after illumi-
nating for approximately sixseconds.
The light comes on while the
vehicle is in motion.
The light blinks when the engine is running.
Have an authorized HYUNDAIdealer inspect the SRS as soon
as possible if any of these con-
ditions occur.
WARNING

Safety system of your vehicle
Air bag deployment depends on anumber of factors including vehicle speed, angles of impact and the
density and stiffness of the vehicles
or objects which your vehicle
impacts during a collision. The
determining factors are not limited
to those mentioned above.
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 acci-
dent. It is much more likely that youwill simply see the deflated air bags
hanging out of their storage com-
partments after the collision.
In addition to inflating in serious 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 pro-tection from ejection, especiallywhen used in conjunction with the
seat belts. To help provide protection, the air
bags must inflate rapidly. Thespeed of air bag inflation is a con-
sequence of extremely short timein which to inflate the air bag
between the occupant and the
vehicle structures before the occu-
pant impacts those structures. This
speed of inflation reduces the risk
of serious or life-threatening
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 theinflation 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, espe-cially 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 needsabout 10 inches (25 cm) of space to
inflate. NHTSA recommends that
drivers allow at least 10 inches
(25 cm) between the center of the
steering wheel and the chest.

Main components of theOccupant Classification System
A detection device located within the front passenger seat cushion.
Electronic system to determine whether the passenger air bag systems (both front and side)
should be activated or deactivated.
An indicator light located on the instrument panel which illuminates
the words "PASSENGER AIR BAGOFF" indicating the front passen-
ger air bag system is deactivated.
The instrument panel air bag indi- cator light is interconnected with
the OCS. Front passenger seat adult occu-
pants who are properly seated and
wearing the seat belt properly,should not cause the passenger air
bag to be automatically 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 otherwisebeing 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 center
facia panel. This system detects the
conditions 1-4 in the following table
and activates or deactivates the frontpassenger air bag based on these
conditions.
Always be sure that you and all vehi-
cle occupants are seated properly
and wearing the seat belt properly for
the most effective protection by theair 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.
