NOTICE
• Both the driver's and front passen-
ger's pre-tensioner seat belts may be
activated in certain frontal collisions.
The pre-tensioners will not activate if
the seat belts are not worn at the time
of the collision.
• When the pre-tensioner seat belts are activated, a loud noise may be heard
and fine dust, which may appear to be
smoke, may be visible in the passenger
compartment. These are normal oper-
ating conditions and are not haz-
ardous.
• Although it is harmless, the fine dust may cause skin irritation and should
not be breathed for prolonged peri-
ods. Wash all exposed skin areas thor-
oughly after an accident in which the
pre-tensioner seat belts were activat-
ed.
✽ ✽ NOTICE
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 illuminate for approximately
6 seconds after the ignition switch has
been turned to the ON position, and
then it should turn off.CAUTION
If the pre-tensioner seat belt does
not work properly, this warning lightwill illuminate even if the SRS air bag has not malfunctioned. If theSRS air bag warning light does notilluminate when the ignition switch is turned ON, or if it remains illumi-nated after illuminating for approxi- mately 6 seconds, or if it illuminateswhile the vehicle is being driven, please have an authorized Kia deal-er inspect the pre-tensioner seatbelt or SRS air bag system as soonas possible.

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.

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.

belt buckle sensors
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.

When an adult is seated in the front pas-
senger seat, if the PASSENGER AIR
BAG “OFF” indicator is on, turn the igni-
tion switch to the LOCK position and ask
the passenger to sit properly (sitting
upright with the seat back in an upright
position, centered on the seat cushion
with their seat belt on, legs comfortably
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 passenger air bag. If the PASSENGER AIR BAG “OFF” indi-
cator is still on, ask the passenger to
move to the rear seat.
✽ ✽
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 occupant detection sensor
will then classify the front passenger
after several more seconds.

WARNING
Do not allow an adult passenger to
ride in the front seat when the PAS-
SENGER AIR BAG “OFF” indicator
is illuminated, because the air bag
will not deploy in the event of a
crash. If the PASSENGER AIR BAG
“OFF” indicator remains illuminat-
ed after the passenger repositions
themselves properly 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.
Front seat passengers must stay
properly seated to avoid serious
injury from a deploying air bag.
WARNING
Do not put a heavy load in the front
passenger seat. Do not place any
items under the front passenger
seat. Any of these could interfere
with proper sensor operation.

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.

Safety features of your vehicle
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 restrainted 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.

Safety features of your vehicle
The side impact air bags are designed to
deploy only during certain side-impact
collisions, depending on the crash sever-
ity, angle, speed and point of impact. The
side air bags are not designed to deploy
in all side impact situations.(Continued)
For best protection from the sideimpact air bag system and to
avoid being injured by the
deploying side impact air bag,
both front seat occupants should
sit in an upright position with the
seat belt properly fastened. The
driver's hands should be placed
on the steering wheel at 9:00 and
3:00 positions. The passenger's
arms and hands should be
placed on their laps.
Do not use any accessory seat covers.
Use of seat covers could reduce or prevent the effectiveness of
the system.
Do not install any accessories on the side or near the side impact
air bag.
Do not place any objects over the air bag or between the air bag
and yourself.
(Continued)(Continued)
Do not place any objects (anumbrella, bag, etc.) between the
front door and the front seat.
Such objects may become dan-
gerous projectiles and cause
injury if the supplemental side air
bag inflates.
To prevent unexpected deploy- ment of the side impact air bag
that may result in personal injury,
avoid impact to the side impact
sensor when the ignition switch
is on.
If the seat or seat cover is dam- aged, have the vehicle checked
and repaired by an authorized Kia
dealer. Inform the dealer that your
vehicle is equipped with side
impact air bags.
WARNING
Do not allow the passengers tolean their heads or bodies onto
doors, put their arms on the
doors, stretch their arms out of
the window, or place objects
between the doors and passen-
gers when they are seated on
seats equipped with side and/or
curtain air bags.
The side impact air bag is sup- plemental to the driver's and the
passenger's seat belt systems
and is not a substitute for them.
Therefore your seat belts must be
worn at all times while the vehicle
is in motion. The air bags deploy
only in certain side impact condi-
tions severe enough to cause
significant injury to the vehicle
occupants.

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.

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 bumper guards or
replacing a bumper with non-gen-
uine parts may adversely affect
your vehicles collision and air
bag deployment performance.
