Pre-tensioner safety belt
Your vehicle is equipped with driver's and
front passenger's pre-tensioner safety
belts. The purpose of the pre-tensioner
is to make sure that excess slack is taken
up in certain frontal collisions. The pre-
tensioners may activate along with the
front air bags in frontal collisions based
on angle of impact, seat belt usage and
impact severity.
✽
NOTICE
The pre-tensioner seat belt is installed at
the front seats, and the sensor is
equipped inside the buckle, where pres-
ence of passenger is sensed by the fas-
tening of the seat belts. Therefore, pre-
tensioner will not activate if the passen-
ger is not fastened with the seat belts.
Likewise, it will activate if buckled even
without a passenger in the seat. Pre-ten-
sioner seat belt is designed to activate
when the seatbelt is in use. To ensure the
pretensioner seatbelts activate in event
of a possible seatbelt buckle switch mal-
function, the system is designed to acti-
vate regardless of whether a seat belt is
in use or if no seat belt use is detected
within 6 seconds of turning the ignition
switch ON.
The seat belt pre-tensioner system con-
sists mainly of the following components.
Their locations are shown in the illustra-
tion.

Air bag system components
The main components of your SRS are:
• To indicate that your vehicle is
equipped with air bags, the corre-
sponding air bag covers are marked
with “SRS AIR BAG”.
- Driver’s air bag
- Driver’s knee air bag
- Front passenger’s air bag
- Curtain air bag
• A diagnostic system that continually
monitors the system operation.
• An indicator light to warn you of a pos-
sible problem with the system.
• Emergency power backup in case your
car’s electrical system is disconnected
in a crash.
Your vehicles SRS uses a variety of sen-
sors to monitor the driver’s and front pas-
senger’s safety belt usage and impact
severity.
The safety belt usage sensors determine
if the driver and front passenger’s safety
belts are fastened. These sensors pro-
vide the ability to control the SRS deploy-
ment based on whether or not the safety
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.
According to the impact severity and
safety belt usage, the SRSCM (SRS
Control Module) controls the air bag infla-
tion. Failure to properly wear safety belts
can increase the risk or severity of injury
in an accident.
Additionally, your SRS is equipped with
an occupant classification system in the
front passenger’s seat. The occupant
classification system detects the pres-
ence of a passenger in the front passen-
ger’s seat and will turn off the front pas-
senger’s air bag under certain conditions.
For more detail, see “Occupant
Classification System” later in this sec-
tion.
(Continued)
They will generally not provide
protection in side impacts (except
curtain air bags) or rear impacts,
rollovers,less severe frontal colli-
sions. They will not provide pro-
tection from later impacts in a
multi-impact collision.
• If your vehicle has been subject-
ed to flood conditions (e.g.
soaked carpeting/standing water
on the floor of the vehicle, etc.) or
if your vehicle has become flood
damaged in any way, do not
attempt to start the vehicle or put
the key in the ignition before dis-
connecting the battery. This may
cause air bag deployment, which
could result in serious personal
injury or death. If your vehicle has
been subjected to flooded condi-
tions, before attempting to start
the vehicle, have the vehicle
towed to an authorized Kia dealer
for inspection and necessary
repairs.

✽
NOTICE
 If luggage or other objects are placed
on the front passenger's seat or if the
temperature of the seat changes while
the seat is unoccupied, the "PASSEN-
GER AIR BAG OFF" indicator may
blink. These conditions do not indi-
cate a problem.
 Do not put heavy objects on the front
passenger's seat. This may cause front
passenger air bag deployment in the
event of an accident, thus increasing
your repair costs.

-Always sit in a proper seating
position. - Never place feet on the dash-
board.

• Do not modify or replace the front
passenger’s seat. Don't place or
attach anything on the front pas-
senger’s seat. This can adversely
affect the occupant classification
system.
• Do not place sharp objects on the
front passenger seat. These can
damage the occupant classifica-
tion system, if they puncture the
seat cushion.
• Do not install accessory seat cov-
ers on the front seats,since these
will interfere with proper sensor
operation.

Why didn’t my air bag go off in a
collision?
(Inflation and non-inflation conditions
of the air bag)
There are many types of accidents in
which the air bag would not be expected
to provide additional protection.
These include rear impacts, second or
third collisions in multiple impact acci-
dents, as well as low speed impacts. In
other words, just because your vehicle is
damaged and even if it is totally unus-
able, don’t be surprised that the air bags
did not inflate.

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 severe 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 the
authorized Kia dealer.
• Problems may arise if the sensor
installation angles are changed
due to the deformation of front
bumper, body or B pillar where
side collision sensors are
installed. Have the vehicle
checked and repaired by the
authorized Kia dealer.
(Continued)
(Continued)
• 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.
Air bag inflation condition
Front air bag
Front air bags (driver’s and front passen-
ger’s air bags and driver’s knee air bag)
are designed to inflate when the impact
is delivered to front collision sensors
depending on the intensity, speed or
angles of impact of the front collision -
generally from an area a little to the left to
a little to the right of straight ahead.

Knowing your vehicle
Curtain air bag
Curtain air bags are designed to inflate
when the impact signal is delivered to the
side collision sensors, depending on the
severity, speed, and/or angle of the
impact or rollover.Although the front air bags (driver’s and
front passenger’s air bags and driver’s
knee air bag) are designed to inflate only
in frontal collision, it may inflate in any
collision if front impact sensors detect a
sufficient impact.
Curtain air bags are designed to inflate
only in side impact collision, but may
inflate in any collision if side impact sen-
sors detect a sufficient impact.
If the vehicle chassis is impacted by
bumps or objects on unimproved roads
or sidewalks, air bags may deploy. Drive
carefully on unimproved roads or on sur-
faces not designed for vehicle traffic to
prevent unintended air bag deployment.
To protect occupants, front air bags and
pre-tensioner safety belts may deploy in
certain side impact collisions.
Air bag non-inflation conditions
• In collisions, the vehicle safety belts
are sufficient to protect the vehicle
occupants and the air bags may not
deploy. In some cases, deploying air
bags in low-speed collisions can cause
a secondary impact to the occupants
(light abrasions, cuts, burns, etc.), or
loss of vehicle control.

Knowing your vehicle
• Just before impact, drivers often brake
heavily. 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 altered by such “under-ride” col-
lisions.• Air bags may not inflate in rollover acci-
dents. Air bag deployment would not
provide proper protection to the occu-
pants.
However, curtain air bags may inflate
when the vehicle is rolled over by a
side impact collision.• 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.
