The seat belt pre-tensioner system con-
sists mainly of the following components.
Their locations are shown in the illustra-
tion:
1. SRS air bag warning light
2. Retractor pre-tensioner assembly
3. SRS control module
4. Anchor pre-tensioner assembly
✽ ✽NOTICE
• Both the driver's and front passen-
ger's pre-tensioner seat belts may be
activated in certain frontal or side col-
lisions or rollovers.
The pre-tensioners will not be activat-
ed if the seat belts are not being worn
at the time of the collision.
• 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 oper-
ating conditions and are not haz-
ardous.
• Although it is harmless, the fine dust may cause skin irritation and should
not be breathed for prolonged periods.
Wash all exposed skin areas thorough-
ly after an accident in which the pre-
tensioner seat belts were activated.
• Because the sensor that activates the SRS air bag is connected with the pre-
tensioner seat belt, the SRS air bag
warning light on the instrument
panel will illuminate for approximate-
ly 6 seconds after the ignition switch
has been turned to the ON position,
and then it should turn off.

WARNING
To obtain maximum benefit from a
pre-tensioner seat belt:
1. The seat belt must be worn cor-
rectly and adjusted to the proper
position. Please read and follow
all of the important information
and precautions about your vehi-
cle’s occupant safety features –
including seat belts and air bags
– that are provided in this manu-
al.
2. Be sure you and your passen- gers always wear seat belts prop-
erly.

How does the air bag system
operate
Air bags are activated (able to inflate ifnecessary) only when the ignition
switch is turned to the ON or START
position.
Air bags inflate instantly in the event of serious frontal or side collision in order
to help protect the occupants from seri-
ous physical injury.
There is no single speed at which the air bags will inflate.
Generally, air bags are designed to
inflate by the severity of a collision and
its direction. These two factors deter-
mine whether the sensors send out an
electronic deployment/ inflation signal.
Air bag deployment depends on a number of factors including vehicle
speed, angles of impact and the densi-
ty and stiffness of the vehicles or
objects which your vehicle hits in the
collision. Though, factors are not limit-
ed 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 accident.
It is much more likely that you will sim-
ply 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 impact air bags
and curtain air bags will inflate if the
sensing system detects a rollover.
When a rollover is detected, side
impact air bags and curtain air bags
will remain inflated longer to help pro-
vide protection from ejection, especial-
ly when used in conjunction with the
seat belts.
In order to help provide protection in a severe collision, the air bags must
inflate rapidly. The speed of air bag
inflation is a consequence of the
extremely short time in which a collision
occurs and the need to get 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 life-
threatening injuries in a severe collision
and is thus a necessary part of air bag
design.
However, air bag inflation can also
cause injuries which normally 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 exces-
sively close to the air bag.
WARNING
To avoid severe personal injuryor death caused by deploying air
bags in a collision, the driver
should sit as far back from the
steering wheel air bag as possi-
ble (at least 10 inches (250 mm)
away). The front passengers
should always move their seats
as far back as possible and sit
back in their seat.
Air bags inflate instantly in the event of collision, and passen-
gers may be injured by the air bag
expansion force if they are not in
proper position.
Air bag inflation may cause injuries which normally include
facial or bodily abrasions,
injuries from broken glasses or
burns by the air bag inflation
gasses.

Air bag warning light
The purpose of air bag warning light in
your instrument panel is to alert you of a
potential problem with your air bag -
Supplemental Restraint System (SRS).
When the ignition switch is turned ON,
the indicator light should illuminate for
approximately 6 seconds, then go off.
Have the system checked if:
The light does not turn on briefly whenyou turn the ignition ON.
The light stays on after illuminating for approximately 6 seconds.
The light comes on while the vehicle is in motion.
The light blinks when the ignition switch is in ON position.
SRS components and functions
The SRS consists of the following com-
ponents:
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” indi- cator (Front passenger’s seat only)
11. Occupant detection system (Front passenger’s seat only) 12. Driver’s and front passenger’s seat
belt buckle sensors
13. Anchor pre-tensioner
14. Side pressure 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.

Main components of occupant
detection system
A detection device located within thefront passenger seat.
Electronic system to determine whether the front passenger air bag
system should be activated or deacti-
vated.
A warning light located on the instru- ment panel which illuminates the
words PASSENGER AIR BAG "OFF"
indicating the front passenger air bag
system is deactivated.
The instrument panel air bag warning light is interconnected with the occu-
pant detection system.
The ODS is designed to detect the pres-
ence of a properly-seated front passen-
ger 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 detection 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 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.
Always be sure that you and all vehicle
occupants are seated and restrained
properly (sitting upright with the seat in
an upright position, centered on the seat
cushion, with the person's legs comfort-
ably extended, feet on the floor, and
wearing the safety belt properly) for the
most effective protection by the air bag
and the safety belt. The ODS may not function properly if
the passenger takes actions which can
affect the detection system. These
include:
(1) Failing to sit in an upright position.
(2) Leaning against the door or center console.
(3) Sitting towards the sides or the front of the seat.
(4) Putting legs on the dashboard or resting them on other locations.
(5) Improperly wearing the safety belt.
(6) Reclining the seat back.
(7) Unauthorized replacement of seat cover.
(8) Covering seat with blanket

Safety features of your vehicle
When an adult is seated in the front pas-
senger seat, if the PASSENGER AIR
BAG "OFF" indicator is on, turn the igni-
tion switch to the LOCK or OFF position
and ask the passenger to sit properly
(sitting upright with the seat back in an
upright position, centered on the seat
cushion with their seat belt on, legs com-
fortably extended and their feet on the
floor). Restart the engine and have the
person remain in that position. This will
allow the system to detect the person
and to enable the passenger air bag.
If the PASSENGER AIR BAG "OFF" indi-
cator is still on, ask the passenger to
move to the rear seat.
✽ ✽NOTICE
The PASSENGER AIR BAG "OFF"
indicator illuminates for about 4 sec-
onds after the ignition switch is turned
to the ON position or after the engine is
started. If the front passenger seat is
occupied, the occupant detection sensor
will then classify the front passenger
after several more seconds.

Proper position
WARNING
Do not allow an adult passenger to
ride in the front seat when the PAS-
SENGER AIR BAG "OFF" indicator
is illuminated because the air bag
will not deploy in the event of a
crash. If the PASSENGER AIR BAG
"OFF" indicator remains illuminat-
ed after the adult passenger reposi-
tions themselves properly and the
car is restarted, it is recommended
that passenger move to the rear
seat because the passenger's front
air bag will not deploy.
Front seat passengers must stay
properly seated to avoid serious
injury from a deploying air bag.
WARNING
Do not put a heavy load in the front
passenger seatback pocket or on the
front passenger seat. Do not hang
onto the front passenger seat. Do not
hang any items, such as a seatback
table, on the front passenger seat-
back. Do not place feet on the front
passenger seatback. Do not place
any items under the front passenger
seat. Any of these could interfere
with proper sensor operation.
WARNING
Even though your vehicle is
equipped with the occupant
detection system, never install a
child restraint system in the front
passenger's seat. A deploying air
bag can forcefully strike a child
resulting in serious injuries or
death. Any child age 12 and
under should ride in the rear seat.
Children too large for child
restraints should use the avail-
able lap/shoulder belts. No matter
what type of crash, children of all
ages are safer when restrained in
the rear seat.

Safety features of your vehicle
Driver's and passenger's front air
bag
Your vehicle is equipped with an
Advanced Supplemental Restraint (Air
Bag) System and lap/shoulder belts at
both the driver and passenger seating
positions. The indications of the system's
presence are the letters "SRS AIR BAG"
or “AIR BAG" embossed on the air bag
pad cover in the steering wheel and the
passenger's side front panel pad above
the glove box.
The SRS consists of air bags installed
under the pad covers in the center of the
steering wheel and the passenger's side
front panel above the glove box.The purpose of the SRS is to provide the
vehicle's driver and/or the front passen-
ger 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 gath-
er information about the driver's seat
position, the driver's and front passen-
ger's seat belt usage and impact severi-
ty.
WARNING
If the occupant detection system is
not working properly, the SRS air
bag warning light on the instru-
ment panel will illuminate because
the passenger's front air bag is
connected with the occupant
detection system. If there is a mal-
function of the occupant detection
system, the PASSENGER AIR BAG
"OFF" indicator will not illuminate
and the passenger's front air bag
will inflate in frontal impact crashes
even if there is no occupant in the
front passenger's seat. If the SRS
air bag warning light does not illu-
minate when the ignition switch is
turned to the ON position, remains
illuminated after approximately 6
seconds when the ignition switch is
turned to the ON position, or if it
illuminates while the vehicle is
being driven, have an authorized
HYUNDAI dealer inspect the occu-
pant detection system and the SRS
air bag system as soon as possible.

The seat belt buckle sensors determine if
the driver and front passenger's seat
belts are fastened. These sensors pro-
vide the ability to control the SRS deploy-
ment 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 lev-
els. A first stage level is provided for mod-
erate-severity impacts. A second stage
level is provided for more severe impacts.
According to the impact severity and seat
belt usage, the SRSCM (SRS Control
Module) controls the air bag inflation.
Failure to properly wear seat belts can
increase the risk or severity of injury in
an accident.
Additionally, your vehicle is equipped
with an occupant detection system in the
front passenger's seat. The occupant
detection system detects the presence of
a passenger in the front passenger's seat
and will turn off the front passenger's air
bag under certain conditions. For more
detail, see "Occupant detection system"
in this section.
✽ ✽
NOTICE
• Be sure to read information about the
SRS on the labels provided on the sun
visor.
• Advanced air bags are combined with pre-tensioner seat belts to help pro-
vide enhanced occupant protection in
frontal crashes. Front air bags are not
intended to deploy in collisions in
which protection can be provided by
the pre-tensioner seat belt.
WARNING
If the occupant detection system is
not working properly, the SRS air
bag warning light on the instru-
ment panel will illuminate because
the SRS air bag warning light is
connected with the occupant
detection system. If the SRS air bag
warning light does not illuminate
when the ignition switch is turned
to the ON position, remains illumi-
nated after approximately 6 sec-
onds when the ignition switch is
turned to the ON position, or if it
illuminates while the vehicle is
being driven, have an authorized
HYUNDAI dealer inspect the
advanced SRS air bag system as
soon as possible.
WARNING
Do not place any objects under-
neath the front seats as they could
interfere with the occupant detec-
tion system.

Curtain air bag
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 cer-
tain side impact collisions.
The curtain air bags are designed to
deploy only during certain side impact
collisions, depending on the crash sever-
ity, angle, speed and impact. The side
impact air bags 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 situa-
tions.
(Continued)
Use of seat covers could reduceor prevent the effectiveness of
the system.
Do not install any accessories on the side or near the side air bag.
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 pil-
lar.
Do not place any objects between the door and the seat. They may
become dangerous projectiles if
the side air bag inflates.
Do not place any objects (an umbrella, bag, etc.) between the
front door and the front seat.
Such objects may become dan-
gerous projectiles and cause
injury if the supplemental side air
bag inflates.
Do not put any objects between the side air bag label and seat
cushion. It could cause harm if
the vehicle is in a crash severe
enough to cause the air bags to
deploy.
(Continued)(Continued)
To prevent unexpected deploy-ment of the side impact air bag
that may result in personal injury,
avoid impact to the side impact
sensor when the ignition switch
is on.
If the seat or seat cover is dam- aged, have the vehicle checked
and repaired by an authorized
HYUNDAI dealer because your
vehicle is equipped with side
impact air bags and an occupant
detection system.

Why didn’t my air bag go off in a
collision? (Inflation and non-infla-
tion conditions of the air bag)
There are many types of accidents in
which the air bag would not be expect-
ed to provide additional protection.
These include rear impacts, second or
third collisions in multiple impact
accidents, as well as low speed
impacts.

Air bag inflation conditions
Front air bags
Front air bags are designed to inflate in a
frontal collision depending on the intensi-
ty, speed or angles of impact of the front
collision.Side impact and curtain air bags
(if equipped)
Side impact and curtain air bags are
designed to inflate when a side impact of
sufficient severity is detected.
WARNING
Do not hit or allow any objects to
impact the locations where air
bags or sensors are installed.
This may cause unexpected air
bag deployment, which could
result in serious personal injury
or death.
If the installation location or angle of the sensors is altered in
any way, the air bags may deploy
when they should not or they may
not deploy when they should,
causing severe injury or death.
Therefore, do not try to perform
maintenance on or around the air
bag sensors. Have the vehicle
checked and repaired by an
authorized HYUNDAI dealer.
Problems may arise if the sensor installation angles are changed
due to the deformation of the
front bumper, body or B pillars or
front door where side collision
sensors are installed. Have the
vehicle checked and repaired by
an authorized HYUNDAI dealer.

(Continued)
Your vehicle has been designedto absorb impact and deploy the
air bag(s) in certain collisions.
Installing bumper guards or
replacing a bumper with non-gen-
uine parts may adversely affect
your vehicle's collision and air
bag deployment performance.
