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 higher
amperage 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 tempo-
rary repair. It may cause
extensive wiring damage and
a possible fire.
CAUTION
Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the
system.

Maintenance
✽ ✽
NOTICE
• When replacing 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.
Inner panel fuse replacement
1. Turn the ignition switch and all
other switches off.
2. Open the fuse panel cover.
If the switch is located in the “OFF”
position, a caution indicator will be
displayed in the cluster.
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 new
fuse or relay fits tightly into
the clips. Failure to tightly
install the fuse or relay may
cause damage to the wiring
and electric systems.
Do not remove fuses, relays
and terminals fastened with
bolts or nuts. The fuses, relays
and terminals may not be fas-
tened correctly which may
cause vehicle damage.

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 specified
wattage.
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
network failure or vehicle electrical
control system malfunction. If there is
a problem, we recommend the sys-
tem 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 on
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 light,
firmly apply the parking brake,
ensure that the ignition switch
is turned to the LOCK position
and turn off the lights to avoid
sudden movement of the vehi-
cle, burns to your skin or fin-
gers, or an electric shock.
CAUTION -Light replace-
ment
Be sure to replace the burned-
out bulb with one of the same
wattage rating. Otherwise, it
may cause damage to the fuse
or electric wiring system.
CAUTION -Headlamp
Lens
To prevent damage, do not
clean the headlamp lens with
chemical solvents or strong
detergents.
