The seat belt pre-tensioner system
consists mainly of the following com-
ponents. Their locations are shown in
the illustration:
(1) SRS air bag warning light
(2) Retractor pre-tensioner assembly
(3) SRS control module
(4) Emergency fastening device
(EFD)
✽ ✽NOTICE
• Both the driver's and front pas-
senger's seat belt pre-tensioner
system may be activated not only
in certain frontal collision but also
in certain side collision or rollover,
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.

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.

SRS components and functions
The SRS consists of the following
components:
(1) Driver's front air bag module
(2) Passenger's front air bag module
(3) Side 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 (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) Emergency fastening device
(EFD)
(14) Side pressure sensor
The SRS 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. If the air bag warning light illuminat-
ed for more than, 6 seconds after the
ignition is turned on, or of it illumi-
nates during vehicle operation, an
SRS component may not be func-
tioning properly and you should have
your vehicle checked by an author-
ized Kia dealer.

✽ ✽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 13 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. Any child age 13 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.
✽ ✽

NOTICE
The front passenger seat, dashboard
or door should not be replaced
except by an authorized Kia dealer
using original Kia parts designed for
this vehicle and model. Any other
such replacement or modification
could adversely affect the operation
of the occupant detection system
and the air bag system.

Safety features of your vehicle
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.
WARNING
Modification to the seat struc-
ture can cause the air bag to
deploy at a different 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- 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- 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.

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 and/or B pillar where side
collision sensors are installed. Have
the vehicle checked and repaired by
an authorized 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 bodily
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.
