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 (if
equipped with side impact air bag or
curtain air bag) in order 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 col-
lision and its direction. These two fac-
tors determine whether the sensors
produce an electronic deployment/
inflation signal.
Air bag deployment depends on a number of complex factors including
vehicle speed, angles of impact and
the density and stiffness of the vehi-
cles or objects which your vehicle hits
in the collision. Though, 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 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 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 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 can include facial
abrasions, bruises and broken bones
because the inflation speed also caus-
es the air bags to expand with a great
deal of force.
There are even circumstances under which contact with the steer-
ing wheel air bag can cause fatal
injuries, especially if the occupant
is positioned excessively close to
the steering wheel.
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 250 mm (10 inches)
away). The front passenger
should always move their seat as
far back as possible and sit back
in their seat.
Air bags inflate instantly in an event of a collision, and passen-
gers may be injured by the air bag
expansion force if they are not in
a 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.

Noise and smoke
When the air bags inflate, they make a
loud noise and they leave smoke and
powder in the air inside of the vehicle.
This is normal and is a result of the igni-
tion of the air bag inflator. After the air
bag inflates, you may feel substantial dis-
comfort in breathing due to the contact of
your chest to both the seat belt and the
air bag, as well as from breathing the
smoke and powder. Open your doors
and/or windows as soon as possible
after the impact in order to reduce dis-
comfort and prevent prolonged expo-
sure to smoke and powder.
Though smoke and powder are non-
toxic, it may cause irritation to the skin
(eyes, nose and throat etc). If this is the
case, wash and rinse with the cold water
immediately and consult the doctor if the
symptom persists.
Installing a child restraint on a front passenger’s seat is forbidden
Never place a rear-facing child restraint
in the front passenger’s seat. If the air
bag deploys, it would impact the rear-fac-
ing child restraint, causing serious or
fatal injury.
In addition, do not place front-facing child
restraint in the front passenger’s seat
either. If the front passenger air bag
inflates, it would cause serious or fatal
injuries to the child.

WARNING
When the air bags deploy, the air
bag related parts in the steering
wheel and/or instrument panel
and/or in both sides of the roof rails
above the front and rear doors are
very hot. To prevent injury, do not
touch the air bag storage area’s
internal components immediately
after an air bag has inflated.

Air bag warning light
The purpose of the 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.
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)
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)
WARNING
Extreme Hazard! Do not use arearward facing child restraint on
a seat protected by an air bag in
front of it!
Never put a child restraint in the front passenger’s seat. If the front
passenger air bag inflates, it can
cause serious or fatal injuries.
When children are seated in the rear outboard seats of a vehicle
equipped with side and/or curtain
air bags, be sure to install the
child restraint system as far away
from the door side as possible,
and securely lock the child
restraint system in position.
Inflation of side and/or curtain air
bags could cause serious injury
or death to an infant or child.

13. Anchor pre-tensioner assembly
*: if equipped
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.
The SRS air bag warning light on the
instrument panel will illuminate for about
6 seconds after the ignition switch is
turned to the ON position, after which the
air bag warning light should go out.
If any of the following conditions occurs,
this indicates a malfunction of the SRS.
Have an authorized Kia dealer inspect
the air bag system as soon as possible.
The light does not turn on briefly when you 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 air bag modules are located both in
the center of the steering wheel and in
the front passenger's panel above the
glove box. When the SRSCM detects a
sufficiently severe impact to the front of
the vehicle, it will automatically deploy
the front air bags.
Upon deployment, tear seams molded
directly into the pad covers will separate
under pressure from the expansion of the
air bags. Further opening of the covers
then allows full inflation of the air bags.

Passenger’s front air bag
A fully inflated air bag, in combination
with a properly worn seat belt, slows the
driver's or the passenger's forward
motion, reducing the risk of head and
chest injury.
After complete inflation, the air bag
immediately starts deflating, enabling the
driver to maintain forward visibility and
the ability to steer or operate other con-
trols.

WARNING
Do not install or place any acces-sories (drink holder, cassette
holder, sticker, etc.) on the front
passenger's panel above the
glove box in a vehicle with a pas-
senger's air bag. Such objects
may become dangerous projec-
tiles and cause injury if the pas-
senger's air bag inflates.

When installing a container of liq-uid air freshener inside the vehi-
cle, do not place it near the
instrument cluster nor on the
instrument panel surface.
It may become dangerous projec-
tiles and cause injury if the pas-
senger's air bag inflates.

ODS (Occupant Detection System)
Your vehicle is equipped with an ODS in
the front passenger's seat.
(Continued)
The SRS can function only when
the ignition key is in the ON posi-
tion. If the SRS air bag warning
light does not illuminate, or con-
tinuously remains on after illumi-
nating for about 6 seconds when
the ignition switch is turned to
the ON position, or after the
engine is started, comes on while
driving, the SRS is not working
properly. If this occurs, have your
vehicle immediately inspected by
an authorized Kia dealer.
Before you replace a fuse or dis- connect a battery terminal, turn
the ignition switch to the LOCK
position and remove the ignition
key. Never remove or replace the
air bag related fuse(s) when the
ignition switch is in the ON posi-
tion. Failure to heed this warning
will cause the SRS air bag warn-
ing light to illuminate.WARNING
If an air bag deploys, there maybe a loud noise followed by a fine
dust released in the vehicle.
These conditions are normal and
are not hazardous - the air bags
are packed in this fine powder.
The dust generated during air
bag deployment may cause skin
or eye irritation as well as aggra-
vate asthma for some persons.
Always wash all exposed skin
areas thoroughly with lukewarm
water and a mild soap after an
accident in which the air bags
were deployed.

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 driver's front air bag is
not affected or controlled by the ODS.Main components of ODS
A detection device located within thefront passenger seat track.
Electronic system to determine whether passenger air bag systems
should be activated or deactivated.
A indicator 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.
If the front passenger seat is occupied by
a person that the system determines to
be of adult size, and he/she sits properly
(sitting upright with the seatback in an
upright position, centered on the seat
cushion with their seat belt on, legs com-
fortably extended and their feet on the
floor), the PASSENGER AIR BAG “OFF”
indicator will turn off and the front pas-
senger's air bag will be able to inflate, if
necessary, in frontal crashes.
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 front passenger air bag
based on these conditions. 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 (Occupant Detection System)
may not function properly if the passen-
ger takes actions which can defeat 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 rest- ing them on other locations which
reduce the passenger weight on the
front seat.
(5) Improperly wearing the safety belt.
(6) Reclining the seat back.
