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 Assistance center at 1-
800-333-4Kia. 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.

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 U.S. National
Highway Traffic Safety Administration
(NHTSA), are attached to the sunvi-
sor to alert the driver and passen-
gers of potential risks of the air bag
system.
WARNING- Tampering
with 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 by rendering the SRS
inoperative.
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
If an indicator stays on and does not
flash or if it flashes abnormally, one of
the turn signal bulbs may be burned
out and will require replacement.
✽ ✽NOTICE
If an indicator flash is abnormally
quick or slow, a bulb may be burned
out or have a poor electrical connec-
tion in the circuit.
Check headlight
This warning message illuminates if
there is a malfunction (burned-out
bulb except LED lamp or circuit mal-
function) with the headlamp. In this
case, have your vehicle inspected by
an authorized Kia dealer.
✽ ✽NOTICE
• When replacing the bulb, use the
same wattage bulb.
For more information, refer to
“BULB WATTAGE” in chapter 9.
• If a different wattage bulb is installed on the vehicle, this warn-
ing message is not displayed.
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

The use of chains may adversely
affect vehicle handling.
Do not exceed 20 mph (30 km/h) or the chain manufacturer’s recom-
mended speed limit, whichever is
lower.
Drive carefully and avoid bumps, holes, sharp turns, and other road
hazards, which may cause the
vehicle to bounce.
Avoid sharp turns or locked-wheel braking.Use high quality ethylene gly-
col coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 8. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 8. The level of charge in
your battery can be checked by an
authorized Kia dealer or a service
station.
Change to "winter weight" oil
if necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 9 for recommendations. If
you aren't sure what weight oil you
should use, consult 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.CAUTION- Snow chains
Chains that are the wrong size or improperly installed candamage your vehicle's brakelines, suspension, body andwheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.

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.

Maintenance
✽ ✽NOTICE
• When replacing a fuse, turn the
ignition “OFF” and turn off
switches of all electrical devices
then remove battery (-) terminal.
• The actual fuse/relay panel label may differ from equipped items.
WARNING- Electrical Fire
Always ensure replacements
fuses and relays are securely
fastened when installed. Failure
to do so can result in a vehicle
fire.
CAUTION
When replacing a blown fuse or relay, make sure the newfuse or relay fits tightly intothe clips. Failure to tightlyinstall the fuse or relay maycause damage to the wiringand electric systems.
Do not remove fuses, relays and terminals fastened withbolts or nuts. The fuses, relaysand terminals may not be fas-tened correctly which maycause vehicle damage.
CAUTION
Do not input any other objects except fuses or relays intofuse/relay terminals, such as adriver or wiring. It may causecontact failure and systemmalfunction.
Do not plug in screwdrivers or aftermarket wiring into the ter-minal originally designed forfuse and relays only. The elec-trical system and wiring of thevehicle interior may be dam-aged or burned due to contactfailure.
If you directly connect the wire on the taillight or replacethe bulb which is over the reg-ulated capacity to install trail-ers, etc., the inner junctionblock can get burned.

Maintenance
Main fuse
If the main fuse is blown, it must be
removed as follows:
1. Turn off the engine.
2. Disconnect the negative batterycable.
3. Remove the nuts shown in the pic- ture above.
4. Replace the fuse with a new one of the same rating.
5. Reverse these steps to reinstall the main fuse.
✽ ✽NOTICE
The electronic system may not func-
tion correctly even when the engine
compartment and internal fuse
box’s individual fuses are not dis-
connected. In such case the cause of
the problem may be disconnection
of the main fuse (BFT type), which is
located inside the positive battery
terminal (+) cap.
Since the main fuse is designed more
intricately than other parts, have the
vehicle checked by an authorized
Kia dealer.
✽ ✽NOTICE- Random wiring pro-
hibited when retrofitting equip-
ment
Use of random wiring in the vehicle
might cause danger due to failure
and damage of the vehicle’s per-
formance.
Using random wires especially when
retrofitting AVN or theft alarm sys-
tem, remote engine control, car
phone or radio, might damage the
vehicle or cause fire.
✽ ✽ NOTICE- Remodeling
Prohibited
Do not rewire your vehicle in any
way as doing so may affect the per-
formance of several safety features
in your vehicle. Rewiring your vehi-
cle may also void your warranty and
cause you to be responsible for any
subsequent vehicle damage which
may result.CAUTION
Visually inspect the battery capto ensure it is securely closed.If the battery cap is not securelyclosed, moisture may enter thesystem and damage the electri-cal components.

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 9.
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 specified
wattage.✽ ✽ 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.
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.
