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.

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 theengine 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 circuityou may not need for operating thevehicle, such as the power outletfuse.
If the head lamp, turn signal lamp,
stop signal lamp, fog lamp, DRL, 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.
ODEP079020
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.

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.Multi fuse
If the multi 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 multi fuse.
✽ ✽NOTICE
Do not disassemble nor assemble the
multi fuse when it is secured with
nuts and bolts. Incorrect or partial
assembly torque may cause a fire.
Have the vehicle checked by an
authorized Kia dealer.
ODEP079022
CAUTION
After checking the fuse panel in
the engine compartment,securely install the fuse panelcover to protect against anyelectrical failure which mayoccur from water contact. Listenfor the audible clicking sound toensure the fuse panel cover issecurely fastened.

Main fuse (Plug-in Hybrid)
If the multi 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 multi 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- 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.
WARNING- Random
wiring prohibited when
retrofitting equipment
Use of random wiring in the
vehicle might cause danger due
to failure and damage of the
vehicle’s performance.
Using random wires especially
when retrofitting AVN or theft
alarm system, remote engine
control, car phone or radio
might damage the vehicle or
cause fire.
