replace the battery, contact an
authorized Kia dealer.
1. Remove the mechanical key.
2. Pry open the rear cover.

to heat or sunlight.
An inappropriately dis- posed battery can be harm-
ful to the environment and
human health. Dispose the
battery according to your
local law(s) or regulations.
Smart key immobilizer system
Your vehicle is equipped with an
electronic engine immobilizer system
to reduce the risk of unauthorized
vehicle use.
Your immobilizer system is com-
prised of a small transponder in the
smart key and electronic devices
inside the vehicle.
With the immobilizer system, when-
ever you turn the engine start/stop
button to the ON position by pressing
the button while carrying the smart
key, it verifies if the smart key is valid.
If the key is determined to be valid,
the engine will start.
If the key is determined to be invalid,
the engine will not start.
✽ ✽NOTICE
Do not put metal accessories near
the ignition switch.
Metal accessories may interrupt the
transponder signal and may prevent
the engine from being started.

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.

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.
