How does the air bag system
operate
Air bags are activated (able to inflate if
necessary) 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 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. The determining, fac-
tors 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, passengers
may be injured by the air bag
expansion force if they are not in
a proper position.
Air bag inflation may cause injuries including facial or bodily
abrasions, injuries from broken
glasses or burns.

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 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.

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. Anchor pre-tensioner assemblies*
7. Air bag warning light
8. SRS control module (SRSCM)
9. Front impact sensors
10. Side impact sensors*
11. PASSENGER AIR BAG “OFF” indi- cator (Front passenger’s seat only)
12. 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. Driver’s and front passenger’s seatbelt buckle sensors
*: 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. 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.

WARNING
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 illuminat- ing for approximately 6 seconds.

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
position.The indications of the system's presence
are the letters "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
KIA dealer inspect the occupant
detection system and the SRS air
bag system as soon as possible.

The driver's seat track position sensor (if
equipped), which is installed on the seat
track, determine if the seat is fore or aft
of a reference position. The seat belt
buckle sensors determine if the driver
and front passenger's seat belts are fas-
tened. These sensors provide the ability to con-
trol the SRS deployment based on how
close the driver's seat is to the steering
wheel, 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 with two lev-
els. A first stage level is provided for mod-
erate-severity impacts. A second stage
level is provided for more severe impacts.
The passenger’s front air bag is designed
to help reduce the injury of children sit-
ting close to the instrument panel in low
speed collisions. However, children are
safer if they are restraint in the rear seat.
According to the impact severity, seating
position 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 sever-
ity 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.
WARNING
If a seat track position sensor (if
equipped) or an occupant detection
system is not working properly, the
SRS air bag warning light on the
instrument panel will illuminate
because the SRS air bag warning
light is connected with the seat
track position sensor and the occu-
pant detection system. 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
KIA dealer inspect the advanced
SRS air bag system as soon as
possible.
WARNING
Modification to the seat structure
can adversely affect the seat
track position sensor (if
equipped) and cause the air bag
to deploy at a different level than
should be provided.
Do not place any objects under- neath the front seats as they
could damage the seat track
position sensor or interfere with
the occupant detection system.
Do not place any objects that may cause magnetic fields near the
front seat. These may cause a
malfunction of the seat track
position sensor.

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. In other words, just because
your vehicle is damaged and even if it
is totally unusable, don’t be surprised
that the air bags did not inflate.

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.
1JBA3513
WARNING
Do not hit or allow any objects to
impact the locations where air
bag 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 KIA dealer.

(Continued)
Problems may arise if the sensorinstallation angles are changed
due to the deformation of the
front bumper, body or B pillar
where side collision sensors are
installed. Have the vehicle
checked and repaired by an
authorized KIA dealer.
Your vehicle has been designed to absorb impact and deploy the
air bag(s) in certain collisions.
Installing aftermarket bumper
guards or replacing a bumper
with non-genuine parts may
adversely affect your vehicles
collision and air bag deployment
performance.

Side air bags (if equipped)
Side air bags (side impact and/or curtain
air bags) are designed to inflate when an
impact is detected by side collision sen-
sors depending on the strength, speed or
angles of impact resulting from a side
impact collision.Although the front air bags (driver’s and
front passenger’s air bags) are designed
to inflate only in frontal collisions, they
also may inflate in other types of colli-
sions if the front impact sensors detect a
sufficient impact. Side air bags (side
impact and/or curtain air bags) are
designed to inflate only in side impact
collisions, but they may inflate in other
collisions if the side impact sensors
detect a sufficient impact.
If the vehicle chassis is impacted by
bumps or objects on unimproved roads,
the air bags may deploy. Drive carefully
on unimproved roads or on surfaces not
designed for vehicle traffic to prevent
unintended air bag deployment.
C040802ATD
Air bag non-inflation conditions
In certain low-speed collisions the air
bags may not deploy. The air bags are
designed not to deploy in such cases
because they may not provide benefits
beyond the protection of the seat belts
in such collisions.

Front air bags are not designed to
inflate in rear collisions, because occu-
pants are moved backward by the
force of the impact. In this case, inflat-
ed air bags would not be able to pro-
vide any additional benefit. Front air bags may not inflate in side
impact collisions, because occupants
move to the direction of the collision,
and thus in side impacts, front air bag
deployment would not provide addi-
tional occupant protection.
However, side impact or curtain air
bags may inflate depending on the
intensity, vehicle speed and angles of
impact. In a slant or angled collision, the force
of impact may direct the occupants in a
direction where the air bags would not
be able to provide any additional bene-
fit, and thus the sensors may not
deploy any air bags.

Safety features of your vehicle
Just before impact, drivers often brakeheavily. Such heavy braking lowers the
front portion of the vehicle causing it to
“ride” under a vehicle with a higher
ground clearance. Air bags may not
inflate in this "under-ride" situation
because deceleration forces that are
detected by sensors may be signifi-
cantly replaced by such “under-ride”
collisions. Air bags may not inflate in rollover acci-
dents because air bag deployment
would not provide protection to the
occupants.
However, side impact and/or curtain air
bags may inflate when the vehicle is
rolled over by a side impact collision, if
the vehicle is equipped with side
impact air bags and curtain air bags. Air bags may not inflate if the vehicle
collides with objects such as utility
poles or trees, where the point of
impact is concentrated to one area and
the full force of the impact is not deliv-
ered to the sensors.
