• Both the driver's and front pas-
senger's seat belt pre-tensioner sys-
tem may be activated not only in
certain frontal collision, but also in
certain side collisions or rollovers,
if the vehicle is equipped with a
side or curtain air bag.
• 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 illumi-
nate for approximately 6 seconds
after the ignition switch has been
turned to the ON position, and
then it should turn off.
If the pre-tensioner seat belt system
is not working properly, this warning
light will illuminate even if there is not
a malfunction with the SRS air bag. If
the SRS air bag warning light does
not illuminate when the ignition
switch is turned ON, or if it remains
illuminated after illuminating for
approximately 6 seconds, or if it illu-
minates while the vehicle is being
driven, have an authorized Kia dealer
inspect the pre-tensioner seat belt
and SRS air bag system as soon as
possible.
✽ ✽ NOTICE
Do not attempt to service or repair
the pre-tensioner seat belt system in
any manner. Do not attempt to
inspect or replace the pre-tensioner
seat belts yourself. This must be
done by an authorized Kia dealer.
WARNING - Skin Irritation
Wash all exposed skin areas
thoroughly after an accident in
which the pre-tensioner seat
belts were activated. The fine
dust from the pre-tensioner
activation may cause skin irrita-
tion and should not be breathed
for prolonged periods.

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.
The appropriate air bags inflate instantly in the event of a serious
frontal collision or side collision 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
collision and its direction. These
two factors determine whether the
sensors produce an electronic
deployment/ inflation signal.
Air bag deployment depends on a number of 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 determin-
ing 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
simply see the deflated air bags
hanging out of their storage com-
partments after the collision.
In addition to inflating in serious side collisions, side and/or curtain
air bags will inflate if the sensing
system detects a rollover.
When a rollover is detected, side and/or curtain air bags will remain
inflated longer to help provide pro-
tection from ejection, especially
when used in conjunction with the
seat belts. In order to help provide protection,
the air bags must inflate rapidly.
The speed of the air bag inflation is
a consequence of extremely short
time in 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 the air bag design.
However, air bag inflation can also
cause injuries which can include
facial abrasions, bruises and bro-
ken 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
steering wheel or passenger air
bag can cause fatal injuries,
especially if the occupant is
positioned excessively close to
the steering wheel or passenger
air bag.

✽ ✽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 occu-
pant detection sensor will then clas-
sify the front passenger after several
more seconds.
Even though your vehicle is
equipped with the occupant detec-
tion system, never install a child
restraint system in the front pas-
senger's seat. A deploying air bag
can forcefully strike a child result-
ing 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
available lap/shoulder belts. No
matter what type of crash, children
of all ages are safer when
restrained in the rear seat.
If the PASSENGER AIR BAG “OFF” indicator is illuminated when
the front passenger's seat is occu-
pied by an adult 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 comfortably
extended and their feet on the
floor), have that person sit in the
rear seat.WARNING - “AIR BAG
OFF” light
Do not allow an adult passenger
to ride in the front seat when the
PASSENGER AIR BAG “OFF”
indicator is illuminated,
because the air bag will not
deploy in the event of a crash.
The driver must instruct the
passenger to reposition himself
in the seat. Failure to properly
position yourself may lead to air
bag deactivation resulting in air
bag non-deployment in a colli-
sion. If the PASSENGER AIR
BAG “OFF” indicator remains
illuminated after the passenger
repositions themselves proper-
ly 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.

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
passenger with additional protection
than that offered by the seat belt sys-
tem alone in case of a frontal impact
of sufficient severity. 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 deter-
mine if the driver and front passen-
ger's seat belts are fastened.These sensors provide the ability to
control the SRS deployment based on
whether or not the seat belts are fas-
tened, and how severe the impact is.
The advanced SRS offers the ability
to control the air bag inflation with
two levels. A first stage level is pro-
vided for moderate-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 sitting close to the instru-
ment panel in low speed collisions.
However, children are safer if they
are restrained in the rear seat.
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 occu-
pant 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 cer-
tain conditions. For more detail, see
"Occupant detection system" in this
chapter.
Modification to the seat structure can
cause the air bag to deploy at a dif-
ferent level than should be provided.

The side air bag is supplemental to
the driver's and the passenger's
seat belt systems and is not a sub-
stitute for them. Therefore your
seat belts must be worn at all times
while the vehicle is in operation.
For best protection from the side air bag system and to avoid being
injured by the deploying side air
bag, both front seat occupants
should sit in an upright position
with the seat belt properly fas-
tened. The driver's hands should
be placed on the steering wheel at
the 9:00 and 3:00 positions. The
passenger's arms and hands
should be placed on their laps. If seat or seat cover is damaged,
have the vehicle checked and
repaired by an authorized Kia deal-
er. Inform the dealer that your vehi-
cle is equipped with side air bags
and an occupant detection system.
WARNING- Flying objects
Do not place any objects (an
umbrella, bag, etc.) between the
front door and the front seat.
Such objects may become dan-
gerous projectiles if the side
airbag inflates.
WARNING- Deployment
Do not install any accessories
including seat covers, on the
side or near the side air bag as
this may affect the deployment
of the side air bags.WARNING- Unexpected deployment
Avoid impact to the side impact
airbag sensor when the ignition
switch is ON to prevent unex-
pected deployment of the side
air bag.WARNING- No attaching objects
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 dan-
gerous projectiles if the side
air bag inflates.
Never place or insert any object into any small opening
near side airbag labels
attached to the vehicle seats.
When the air bag deploys, the
object may affect the deploy-
ment and result in unexpected
accident or bodily harm.
Do not install any accessories on the side or near the side air
bags.

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
expected to provide additional pro-
tection.
These include rear impacts, second
or third collisions in multiple impact
accidents, as well as low speed
impacts.Air bag collision sensors

Problems may arise if the sensor
installation angles are changed due
to the deformation of the front
bumper, front end module, body or
front doors where side collision sen-
sors are installed. Have the vehicle
checked and repaired by an author-
ized Kia dealer.
Installing bumper guards (or side
step or running board) or replacing a
bumper (or front door module) with
non-genuine parts may adversely
affect your vehicle’s collision and air
bag deployment performance.Air bag inflation conditions
Front air bags
Front air bags are designed to inflate
in a frontal collision depending on
the intensity, speed or angles of
impact of the front collision.

WARNING- Air bag sen-sors
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 per-
sonal 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.
Therefore, do not try to per-
form maintenance on or
around the air bag sensors.
Have the vehicle checked and
repaired by an authorized Kia
dealer.

❈ The actual air bags in the vehicle may differ
from the illustration.
Side and/or curtain air bags
Side and/or curtain air bags are
designed to inflate when an impact is
detected by side collision sensors
depending on the strength, speed or
angles of impact resulting from a
side impact collision.
Also, the side and curtain air bags are
designed to inflate when a rollover is
detected by a rollover sensor.
Although the front air bags (driver’s
and front passenger’s air bags) are
designed to inflate in frontal colli-
sions, they also may inflate in other
types of collisions if the front impact
sensors detect a sufficient frontal
force in another type of impact. Side
and curtain air bags are designed to
inflate in certain side impact colli-
sions. They may inflate in other types
of collisions where a side force is
detected by the sensors. Side air bag
and/or curtain air bags may also
inflate where rollover sensors indi-
cate the possibility of a rollover
occurring (even if none actually
occurs) or in other situations, includ-
ing when the vehicle is tilted while
being towed. Even where side and/or curtain air
bags would not provide impact pro-
tection in a rollover, however, they
will deploy to prevent ejection of
occupants, especially those who are
restrained with seat belts.
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.

In an 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 benefit, and thus the
sensors may not deploy any air
bags. Just before impact, drivers often
brake heavily. Such heavy braking
lowers the front portion of the vehi-
cle causing it to “ride” under a vehi-
cle with a higher ground clearance.
Air bags may not inflate in this
"under-ride" situation because
deceleration forces that are detect-
ed by sensors may be significantly
reduced by such “under-ride” colli-
sions. Front air bags may not inflate in all
rollover accidents where the
SRSCM indicates that the front air
bag deployment would not provide
additional occupant protection.
