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) Front retractor pre-tensioner
assembly
(3) SRS control module
(4) Emergency fastening device (EFD)
(5) Rear retractor pre-tensioner assembly (if equipped)
✽ ✽NOTICE
• 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 engine start/stop button has
been changed to 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
engine start/stop button has been
changed to ON 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.

Safety features of your vehicle
When an adult is seated in the front
passenger seat, if the PASSENGER
AIR BAG “OFF” indicator is on,
change Engine Start/Stop button to
the OFF position and ask the pas-
senger to sit properly (sitting upright
with the seat back in an upright posi-
tion, centered on the seat cushion
with their seat belt on, legs comfort-
ably 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 pas-
senger air bag.If the PASSENGER AIR BAG “OFF”
indicator is still on, ask the passen-
ger to move to the rear seat.
✽ ✽
NOTICE
The PASSENGER AIR BAG “OFF”
indicator illuminates for about 4 sec-
onds after Engine Start/Stop button
is turned to the ON position after the
engine is started. If the front passen-
ger seat is occupied, the occupant
detection sensor will then classify
the front passenger after several
more seconds.

Proper position
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.

Safety features of your vehicle
Your vehicle is equipped with an
Advanced Supplemental Restraint
(Air Bag) System and lap/shoulder
belts at both the driver and passen-
ger seating position.
The indication of the system's pres-
ence are the letters "AIRBAG" locat-
ed on the air bag pad cover on 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
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 sensor deter-
mines if the front passenger's seat
belt is 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.

Side air bag
❈The actual air bags in the vehicle may differ
from the illustration.
Your vehicle is equipped with a side
air bag in each front seat. The purpose of the air bag is to pro-
vide the vehicle's driver and/or the
front passenger with additional pro-
tection than that offered by the seat
belt alone.
The side air bags are designed to
deploy during certain side-impact
collisions, depending on the crash
severity, angle, speed and point of
impact. However, when side deploy-
ment threshold is satisfied at front-
impact, side air bags may deploy.
The side air bags may deploy on the side of the impact or on both sides.
The side and/or curtain air bags on both sides of the vehicle will deploy
if a rollover or possible rollover is
detected.
The side air bags are not designed to deploy in all side impact or
rollover situations.

OJF035040
WARNING- Unexpected
deployment
Avoid impact to the side impact
airbag sensor when Engine
Start/Stop button is ON to pre-
vent unexpected deployment of
the side air bag.
WARNING- No attaching objects
No objects (such as crash pad
cover, cellular phone holder,
cup holder, perfume or stickers)
should be placed over or near
the air bag modules on the
steering wheel, instrument
panel, windshield glass, and the
front passenger's panel above
the glove box. Such objects
could cause harm if the vehicle
is in a crash severe enough to
cause the air bags to deploy. Do
not place any objects over the
air bag or between the air bag
and yourself.

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

Safety features of your vehicle
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.
