No modifications or additions
should be made by the user which
would either prevent the seat belt
adjusting devices from operating to
remove slack, or prevent the seat
belt assembly from being adjusted
to remove slack.
When you fasten the seat belt, be careful not to latch the seat belt in
buckles of other seat. It's very dan-
gerous and you may not be pro-
tected by the seat belt properly.
Do not unfasten the seat belt and do not fasten and unfasten the seat
belt repeatedly while driving. This
could result in loss of control, and
an accident causing death, serious
injury, or property damage.
When fastening the seat belt, make sure that the seat belt does
not pass over objects that are hard
or can break easily. Driver's seat belt warning
As a reminder to the driver, the seat
belt warning light will illuminate and
warning chime will sound for approx-
imately 6 seconds each time engine
start/stop button is ON if the seat belt
is unfastened.
WARNING- Seat belt
buckle
Do not allow foreign material
(gum, crumbs, coins, etc.) to
obstruct the seat belt buckle.
This may prevent the seat belt
from fastening securely.

Safety features of your vehicle
If the system senses excessive ten-
sion on the driver or passenger's
seat belt when the pre-tensioner sys-
tem activates, the load limiter inside
the retractor pre-tensioner will release
some of the pressure on the affected
seat belt.
✽ ✽NOTICE
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 operating condi-
tions and are not hazardous.
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)✽ ✽NOTICE
• Both the driver's and front pas-
senger's seat belt pre-tensioner sys-
tem may be activated not only in
certain frontal collisions, 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.

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 engine start/stop
button has been changed to ON, or if
it remains illuminated after illuminat-
ing for approximately 6 seconds, or if
it illuminates 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.
Pre-tensioners are designed to oper-
ate only one time. After activation,
pre-tensioner seat belts must be
replaced. If the pre-tensioner must
be replaced, contact an authorized
Kia dealer.
Seat belt precautions
Infant or small child
All 50 states have child restraint laws.
You should be aware of the specific
requirements in your state. Child
and/or infant seats must be properly
placed and installed in the rear seat.
For more information about the use of
these restraints, refer to “Child
restraint system” in this section.
✽ ✽NOTICE
Small children are best protected
from injury in an accident when
properly restrained in the rear seat
by a child restraint system that meets
the requirements of the Federal
Motor Vehicle Safety Standards.
Before buying any child restraint sys-
tem, make sure that it has a label cer-
tifying that it meets Federal Motor
Vehicle Safety Standard 213. The
restraint must be appropriate for
your child's height and weight.
Check the label on the child restraint
for this information. Refer to “Child
restraint system” in this section.
WARNING- Hot preten-
sioner
Do not touch the pre-tensioner
seat belt assemblies for several
minutes after they have been
activated. When the pre-ten-
sioner seat belt mechanism
fires during a collision the pre-
tensioner becomes hot and can
burn you.

How does the air bag system
operate?
Air bags are activated (able toinflate if necessary) only when the
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
If any of the following conditions
occur, this indicates a malfunction in
the air bag system. Have an author-
ized Kia dealer inspect the air bag
system as soon as possible.
The light does not turn on brieflywhen you change the engine
start/stop button to ON.
The light stays on after illuminating for approximately 6 seconds.
The light comes on while the vehi- cle is in motion.
The light blinks when engine start/stop button is ON position. The front air bag modules are locat-
ed 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 mold-
ed 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.

Safety features of your vehicle
The SRS can function only whenengine start/stop button is ON
position. If the SRS air bag warning
light does not illuminate, or contin-
uously remains on after illuminat-
ing for about 6 seconds when
engine start/stop button is ON
position, or after the engine is
started, comes on while driving,
the SRS is not working properly. If
this occurs, have your vehicle
immediately inspected by an
authorized Kia dealer.
✽ ✽ NOTICE
Before you replace a fuse or discon-
nect a battery terminal, change
Engine Start/Stop button to the OFF
position. Never remove or replace
the air bag related fuse(s) when
engine start/stop button is ON posi-
tion. Failure to heed this warning
will cause the SRS air bag warning
light to illuminate.
Occupant Detection System
(ODS)
Your vehicle is equipped with an
occupant detection system in the
front passenger's seat.
The occupant detection system is
designed to detect the presence of a
properly-seated front passenger and
determine if the passenger's front air
bag should be enabled (may inflate)
or not. Only the front passenger front
air bag is controlled by the Occupant
Detection System. Do not put anything in front of the
passenger air bag indicator.
