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.

3. Pull the suspected fuse straight
out. Use the removal tool provided
on the engine compartment fuse
panel cover.
4. Check the removed fuse; replace it
if it is blown.
Spare fuses are provided in the
engine compartment fuse panel.
5. Push in a new fuse of the same
rating, and make sure it fits tightly
in the clips.
If it fits loosely, consult an authorized
Kia dealer.
If you do not have a spare, use a
fuse of the same rating from a circuit
you may not need for operating the
vehicle, such as the power outlet
fuse.
If the head lamp, turn signal lamp,
stop signal lamp, fog lamp, tail lamp,
HMSL do not work and the fuses are
OK, check the fuse panel in the
engine compartment. If a fuse is
blown, it must be replaced.
✽ ✽
NOTICE
If the headlamp, fog lamp, turn sig-
nal lamp, or tail lamp malfunction
even without any problem to the
lamps, have the vehicle checked by
an authorized Kia dealer for assis-
tance.
✽ ✽
NOTICE
• Set all switches to ON before driv-
ing.
• If the vehicle is going to be unused
for over 1 month, set all switches
to OFF to prevent the batteries
from draining.
CAUTION - Fuse Panel
Covers
The contact points of the
switches may wear out with
excessive use. Please refrain
from excessive use of the
switches (except for long-term
parking for over 1 month).

position, some items such as audio
and digital clock must be reset and
transmitter (or smart key) may not
work properly. When the switch is
Off, the caution indicator will be dis-
played on the instrument cluster.
Always place the fuse switch in the
ON position while driving the vehicle.
If the switch is located in the “OFF”
position, a caution indicator will be
displayed in the cluster.
Engine compartment fuse

fuse is disconnected, remove it by
using the clip designed for chang-
ing fuses located in the engine
compartment fuse box. Upon
removal, securely insert reserve
fuse of the same rating.3. Check the removed fuse; replace it
if it is blown. To remove or insert
the fuse, use the fuse puller in the
engine compartment fuse panel.
4. Push in a new fuse of the same
rating, and make sure it fits tightly
in the clips. If it fits loosely, consult
an authorized Kia dealer.
CAUTION
After checking the fuse panel in
the engine compartment,
securely install the fuse panel
cover through the audible click-
ing sound.

Maintenance
✽ ✽
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.CAUTION
Visually inspect the battery cap
to ensure it is securely closed.
If the battery cap is not securely
closed, moisture may enter the
system and damage the electri-
cal components.
