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.
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.
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.
Do not arbitrarily modify or add-on electric wiring to the
vehicle.
CAUTION
Do not use a screwdriver or anyother metal object to removefuses because it may cause ashort circuit and damage thesystem.

caution
Window tint (especially metallic
film) might cause communication
errors or poor radio reception, and
malfunctioning automatic lighting
system due to reflections from the
mirror tint inside the vehicle. The

the electronic components, causing
malfunctions or damage.

- Electrical wiring repairs
All electrical repairs should be
performed by authorized Kia
dealerships using approved Kia
parts. Using other wiring com-
ponents, especially when retro-
fitting AVN or theft alarm sys-
tem, remote engine control, car
phone or radio may cause vehi-
cle damage and increase the
risk of a vehicle fire.

✽ ✽NOTICE
Do not disassemble nor assemble the
multi fuse when it is secured with

assembly torque may cause a fire.
Have the vehicle checked by an
authorized Kia dealer.
✽ ✽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.
