Safety features of your vehicle
Additionally, your vehicle is equipped
with an occupant detection system in
the front passenger's seat. The occu-
pant 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 cer-
tain conditions. For more detail, see
"Occupant detection system" in this
chapter.
Modification to the seat structure can
cause the air bag to deploy at a dif-
ferent level than should be provided.
Manufacturers are required by gov-
ernment regulations to provide a
contact point concerning modifica-
tions to the vehicle for persons with
disabilities, which modifications may
affect the vehicle’s advanced air bag
system. That contact is Kia’s toll-free
Customer Experience Department at
1-877-KIA-AUTO (1-877-542-2886).
However, Kia does not endorse nor
will it support any changes to any
part or structure of the vehicle that
could affect the advanced air bag
system, including the occupant
detection system.Advanced air bags are combined with
pre-tensioner seat belts to help pro-
vide enhanced occupant protection in
frontal crashes. Front air bags are not
intended to deploy in collisions in
which sufficient protection can be pro-
vided by the pre-tensioner seat belt.
✽ ✽
NOTICE
Air bags can only be used once –
have an authorized Kia dealer
replace the air bag immediately
after deployment.
Front air bags are not intended to
deploy in side-impact, rear-impact or
rollover crashes. However, when
frontal deployment threshold is satis-
fied at side-impact, front air bags
may deploy. In addition, front air bags
will not deploy in frontal crashes
below the deployment threshold.
WARNING- Replacement /
modifications
The front passenger seat, dash-
board or door should not be
replaced except by an author-
ized Kia dealer using original
Kia parts designed for this vehi-
cle and model. Any other such
replacement or modification
could adversely affect the oper-
ation of the occupant detection
system and your advanced air
bags.
WARNING- SRS Wiring
Do not tamper with or discon-
nect SRS wiring or other com-
ponents of the SRS system.
Doing so could result in injury
due to accidental deployment of
the air bags or by rendering the
SRS inoperative.

Safety features of your vehicle
Adding equipment to or modi-
fying your air bag-equipped
vehicle
If you modify your vehicle by chang-
ing your vehicle's frame, bumper sys-
tem, front end or side sheet metal or
ride height, this may affect the opera-
tion of your vehicle's air bag system.
Air bag warning label
Air bag warning labels, some
required by the Canada Motor
Vehicle Safety Standards (CMVSS),
are attached to the sunvisor to alert
the driver and passengers of poten-
tial risks of the air bag system.
WARNING- Tamperingwith SRS
Do not tamper with or discon-
nect SRS wiring, or other com-
ponents of the SRS system.
Doing so could result in the
accidental inflation of the air
bags or render the SRS inoper-
ative.
WARNING- Towing Vehicle
Always have the ignition off
when your vehicle is being
towed. The side air bags may
inflate if the vehicle is tilted
such as when being towed
because of the rollover sensors
in the vehicle.

Features of your vehicle
Headlight leveling device
(if equipped)
Automatic type
To ensure the proper headlight beam
is used under various conditions, the
headlight beam levels are automati-
cally adjusted depending on the
number of passengers, the weight in
the trunk, and other driving condi-
tions.
✽ ✽NOTICE
If the headlight beam is irradiated
to the high or low position, have the
system be inspected by an author-
ized Kia dealer.
Do not attempt to inspect or replace
the wiring yourself.
Dynamic Bending Light (DBL)
(if equipped)
Dynamic Bending Light (DBL) uses
the steering angle and vehicle speed,
to keep your field of vision wide by
swiveling and leveling the headlamp.
Change the switch to the AUTO posi-
tion when the engine is running. The
dynamic Bending Light (DBL) will
operate when the headlamp is ON.
To turn off the DBL, change the
switch to other positions. After turn-
ing the DBL off, headlamp swiveling
no longer occurs, but leveling oper-
ates continuously. If the DBL malfunction indicator
comes on, the DBL is not working
properly. Drive to the nearest safe
location and restart the engine. If the
indicator continuously remains on,
have system be checked by an
authorized Kia dealer.

Check spark plugs and ignition
system
Inspect your spark plugs as
described in chapter 8 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.
Use approved window washer
anti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized Kia dealer and most auto
parts outlets. Do not use engine
coolant or other types of anti-freeze
as these may damage the paint fin-
ish.
Don’t let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to happen
when there is an accumulation of
snow or ice around or near the rear
brakes or if the brakes are wet. If
there is a risk the parking brake may
freeze, apply it only temporarily while
you put the gear shift lever in P (Park,
Automatic Transmission) and block
the rear wheels so the vehicle cannot
roll. Then release the parking brake.
Don't let ice and snow accu-
mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
vehicle to be sure the movement of
the front wheels and the steering
components are not obstructed.

FUSES
❈Left side : Normal , Right side : Blown
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the other in the engine com-
partment near the battery.
If any of your vehicle’s lights, acces-
sories, 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.
Always replace a blown fuse with
one of the same rating.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized Kia
dealer.
Three kinds of fuses are used: blade
type for lower amperage rating, car-tridge type, and multi fuse for higheramperage ratings.
Do not arbitrarily modify or add-on electric wiring to the vehicle.
WARNING- Fuse replace-
ment
Never replace a fuse with any- thing but another fuse of the
same rating.
A higher capacity fuse could cause damage and possibly a
fire.
Never install a wire or alu- minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
a possible fire.
CAUTION
Do not use a screwdriver or anyother metal object to removefuses because it may cause ashort circuit and damage thesystem.

LIGHT BULBS
Bulb replacement precaution
Please keep extra bulbs on hand
with appropriate wattage ratings in
case of emergencies.
Refer to “Bulb Wattage” in chapter 8.
When changing lamps, first turn off
the engine at a safe place, firmly
apply the parking brake and detach
the battery’s negative (-) terminal.
Use only bulbs of the specifiedwattage. net-work failure
The headlamp, taillight, and fog light
may light up when the head lamp
switch is turned ON, and not light up
when the taillight or for light switch is
turned ON. This may be cause by net-
work failure or vehicle electrical control
system malfunction. If there is a prob-
lem, we recommend the system be
serviced by an authorized Kia dealer.
trical control system stabilization
A normally functioning lamp may
flicker momentarily. This momentary
occurrence is due to the stabilization
function of the vehicle's electrical
control system. If the lamp stops
flickering after a few moments, the
vehicle does not require service.
However, if the lamp goes out after
the momentary flickering, or the flick-
ering continues, we recommend the
system be serviced by an authorized
Kia dealer.
WARNING- Working on the lights
Prior to working on the lights,
firmly apply the parking brake,
ensure that the engine
start/stop button is in OFF posi-
tion and turn off the lights to
avoid sudden movement of the
vehicle that may cause burning
your fingers or receiving an
electric shock.
CAUTION -Light replace-
ment
Be sure to replace the burned- out bulb with one of the samewattage rating. Otherwise, itmay cause damage to the fuseor electric wiring system.
CAUTION -Headlamp
Lens
To prevent damage, do notclean the headlamp lens withchemical solvents or strongdetergents.

✽ ✽
NOTICE
• If the light bulb or lamp connector
is removed while the lamp is still
on, the fuse box's electronic sys-
tem may log it as a malfunction.
Therefore, a lamp malfunction
incident may be recorded as a
Diagnostic Trouble Code (DTC) in
the fuse box.
• It is normal for an operating lamp to flicker momentarily. This is due
to a stabilization function of the
vehicle’s electronic control device.
If the lamp lights up normally
after momentarily blinking, then
it is functioning as normal.
However, if the lamp continues to
flicker several times or turns off
completely, there may be an error
in the vehicle’s electronic control
device. Please have the vehicle
checked by an authorized Kia
dealer immediately.
✽ ✽ NOTICE
You can find moisture inside the lens
of lamps after a car wash or driving
in the rain. It is a natural event
caused by the temperature differ-
ence between the inside and the out-
side of the lamp and does not mean a
problem with its functions. The
moisture inside the lamp would dis-
appear if you drive the vehicle with
the headlamp turned on, however,
the level at which the moisture is
removed may differ depending on
the size/location/condition of the
lamp. If the moisture continues to
stay inside the lamp, have the vehicle
checked by an authorized Kia dealer.
If you don’t have the necessary tools,
the correct bulbs and the expertise,
consult an authorized Kia dealer. In
many cases, it is difficult to replace
vehicle light bulbs because other
parts of the vehicle must be removed
before you can get to the bulb. This is
especially true if you have to remove
the headlamp assembly to get to the
bulb(s).
Removing/installing the headlamp
assembly can result in damage to
the vehicle.
If non-genuine parts or substandard
bulbs are used, it may lead to blow-
ing a fuse or other wiring damages.
Do not install extra lamps or LEDs to
the vehicle. If additional lights are
installed, it may lead to lamp mal-
functions and flickering. Additionally,
the fuse box and other writing may
be damaged.
