✽ ✽
NOTICE
• When replacing a fuse, turn the
ignition "OFF", turn off switches
of all electrical devices, and then
remove the 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, such as a screwdriveror wiring, except fuses orrelays into the fuse/relay ter-minals.
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.

Maintenance
✽ ✽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.
✽ ✽ NOTICE- Window tinting pre-
caution
Window tint (especially metallic
film) might cause communication
errors or poor radio reception, and a
malfunctioning automatic lighting
system due to reflections from the
mirror tint inside the vehicle. The
tint installation solution used might
also leak into the electronic compo-
nents, causing malfunctions or dam-
age.
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.
To identify the location of a specific
fuse, please refer to the inside of the
fuse panel cover and the description
list in this section.
CAUTION
Visually inspect the battery cap to ensure it is securely closed.If the battery cap is not securelyclosed, moisture may enter thesystem and damage the electri-cal components.
WARNING
- 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 an Infotainment system
or a theft alarm system, remote
engine control, car phone or
radio may cause vehicle dam-
age and increase the risk of a
vehicle fire.

3. Check the removed fuse; replace itif 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
✽ ✽NOTICE
Do not disassemble nor assemble a
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.
Main fuse
✽ ✽NOTICE
Do not disassemble nor assemble a
main 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.
CAUTION
Always securely install the fuse
panel cover in the engine com-partment to protect againstelectrical failure which mayoccur from water contact.Listen for the audible clickingsound to ensure the fuse panelcover is securely fastened.

✽ ✽
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. If this occurs, the cause
of the problem may be disconnec-
tion 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.
Battery fuse
If the battery fuse is blown, it must be
removed as follows:
1. Disconnect the negative battery
cable.
2. Replace the fuse with a new one of the same rating.
3. Reinstall in the reverse order of removal.

CAUTION
Visually inspect the battery capfor secure closing. If the batterycap is not securely latched, theelectrical system may be dam-aged due to influx of moistureinto the system.
