•Keep the SRS parts and wiringsaway from water or any liquid. Ifthe SRS components are inopera‐tive due to exposure to water orliquids, it may cause fire or severeinjury.
How does the air bag system
operate
• Air bags are activated (able to inflateif necessary) only when the engine
start/stop button is turned to the ON or START position.
• Air bags inflate instantly in the event of a serious frontal collision or side
collision (if equipped with a side air
bag or curtain air bag) in order to
help protect the occupants from seri‐ ous physical injury.
• There is no single speed at which the air bags will inflate.
Generally, air bags are designed to in‐
flate based upon the severity of a
collision and its direction. These two
factors determine whether the sen‐ sors produce an electronic deploy‐
ment/inflation signal. • Air bag deployment depends on a
number of factors including vehicle
speed, angles of impact and the den‐ sity and stiffness of the vehicles or
objects which your vehicle hits in the
collision. The determining factors are
not limited to those mentioned
above.
• The front air bags will completely in‐ flate and deflate in an instant.
It is virtually impossible for you to
see the air bags inflate during an ac‐
cident.
It is much more likely that you will
simply see the deflated air bags
hanging out of their storage com‐ partments after the collision.
NOTICE
nIf equipped with rollover sen‐
sor
Air bags inflate instantly in the
event of a rollover (if equipped with
a side air bag or curtain air bag) in
order to help protect the occupants
from serious physical injury.
• In order to help provide protection in a severe collision, the air bags must
inflate rapidly. The speed of the air bag inflation is a consequence of ex‐
tremely short time in which a collision
occurs and the need 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 in‐
juries in a severe collision and is thus
a necessary part of the air bag de‐
sign.
However, air bag inflation can also cause injuries which can include facial
abrasions, bruises and broken bones
because the inflation speed also cau‐
ses the air bags to expand with a great deal of force.
•
There are even circumstances underwhich contact with the steeringwheel air bag can cause fatal injuries,especially if the occupant is posi‐tioned excessively close to the steer‐ing wheel.

•No objects should be placed overor near the air bag modules on thesteering wheel, instrument panelor the front passenger's panelabove the glove box, because anysuch object could cause harm ifthe vehicle is in a crash severeenough to cause the air bags todeploy.
•Do not tamper with or disconnectSRS wiring or other components ofthe SRS system. Doing so could re‐sult in injury, due to accidental de‐ployment of the air bags or byrendering the SRS inoperative.
•If the SRS air bag warning light re‐mains illuminated while the vehicleis being driven, we recommendthat the system be inspected byan authorized Kia dealer.
•Air bags can only be used once –we recommend that the systembe replaced by an authorized Kiadealer.
(Continued)
(Continued)
•The SRS is designed to deploy thefront air bags only when an impactis sufficiently severe and when theimpact angle is less than 30° fromthe forward longitudinal axis ofthe vehicle. Additionally, the airbags will only deploy once. Seatbelts must be worn at all times.
•Front air bags are not intended todeploy in side-impact, rear-impactor rollover crashes. In addition,front air bags will not deploy infrontal crashes below the deploy‐ment threshold.
•A child restraint system must nev‐er be placed in the front seat. Theinfant or child could be severely in‐jured or killed by an air bag deploy‐ment in case of an accident.
(Continued)
(Continued)
•Children age 12 and under must al‐ways be properly restrained in therear seat. Never allow children toride in the front passenger seat. Ifa child over 12 must be seated inthe front seat, he or she must beproperly belted and the seatshould be moved as far back aspossible.
•For maximum safety protection inall types of crashes, all occupantsincluding the driver should alwayswear their seat belts whether ornot an air bag is also provided attheir seating position to minimizethe risk of severe injury or death inthe event of a crash.Do not sit or lean unnecessarilyclose to the air bag while the vehi‐cle is in motion.

NOTICE
nwithout rollover sensor
However, side and/or curtain air
bags may inflate when the vehicle is
rolled over by a side impact collision,
if the vehicle is equipped with side
air bags and curtain air bags.
SRS Care
The SRS is virtually maintenance-free
and so there are no parts you can safe‐
ly service by yourself. If the SRS air bag
warning light does not illuminate, or
continuously remains on, we recom‐ mend that the system be inspected by
an authorized Kia dealer.
WARNING
•Modification to SRS components orwiring, including the addition ofany kind of badges to the pad cov‐ers or modifications to the bodystructure, can adversely affectSRS performance and lead to pos‐sible injury.
•For cleaning the air bag pad cov‐ers, use only a soft, dry cloth orone which has been moistenedwith plain water. Solvents or clean‐ers could adversely affect the airbag covers and proper deploymentof the system.
•No objects should be placed overor near the air bag modules on thesteering wheel, instrument panel,and the front passenger's panelabove the glove box, because anysuch object could cause harm ifthe vehicle is in a crash severeenough to cause the air bags to in‐flate.
•If the air bags inflate, we recom‐mend that the system be replacedby an authorized Kia dealer.
(Continued)
(Continued)
•Do not tamper with or disconnectSRS wiring, or other componentsof the SRS system. Doing so couldresult in injury, due to accidentalinflation of the air bags or by ren‐dering the SRS inoperative.
•If components of the air bag sys‐tem must be discarded, or if thevehicle must be scrapped, certainsafety precautions must be ob‐served. An authorized Kia dealerknows these precautions and cangive you the necessary informa‐tion. Failure to follow these pre‐cautions and procedures could in‐crease the risk of personal injury.
•If your car was flooded and hassoaked carpeting or water on theflooring, you shouldn't try to startthe engine; we recommend thatyou contact an authorized Kiadealer.
Additional safety precautions
•Never let passengers ride in the cargoarea or on top of a folded down backseat. All occupants should sit upright,
fully back in their seats with their
seat belts on and their feet on the
floor.

A vehicle’s electrical system is protec‐
ted from electrical overload damage by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the others in the engine com‐ partment near the battery.
If any of your vehicle’s lights, accesso‐
ries, or controls do not work, check the
appropriate circuit fuse. If a fuse has blown, the element inside the fuse will
melt.
If the electrical system does not work,
first check the driver’s side fuse panel.
Before replacing a blown fuse, discon‐ nect the negative battery cable.
Always replace a blown fuse with one
of the same rating.
If the replacement fuse blows, this indi‐
cates an electrical problem. Avoid using the system involved and immediately
consult an authorized Kia dealer.
Three kinds of fuses are used: blade
type for lower amperage rating, car‐ tridge type, and multi fuse for higher
amperage ratings.
