For best battery service
• Keep the battery securely mount-ed.
• Keep the battery top clean and dry.
• Keep the terminals and connec- tions clean, tight, and coated with
petroleum jelly or terminal grease.
• Rinse any spilled electrolyte from the battery immediately with a
solution of water and baking soda.
• If the vehicle is not going to be used for an extended time, discon-
nect the battery cables. Always read the following
instructions carefully when
handling a battery.
If any electrolyte gets into your eyes, flush your eyes
with clean water for at least
15 minutes and get immedi-
ate medical attention.
If electrolyte gets on your
skin, thoroughly wash the
contacted area. If you feel
pain or burning sensation,
get medical attention imme-
diately.
An inappropriately disposed battery can be harmful to the
environment and human
health. Dispose the battery
according to your local law(s)
or regulation.
The battery contains lead. Do
not dispose of it after use.
Please return the battery to
an authorized Kia dealer to
be recycled.
Never attempt to recharge the bat-
tery when the battery cables are con-
nected.
WARNING- Risk of explosion
Keep lit cigarettes and
all other flames or
sparks away from the
battery.
The battery contains hydrogen -- a highly
combustible gas which
will explode if it comes
in contact with a flame or
spark.
Keep batteries out of the reach of children
because batteries con-
tain highly corrosive
SULFURIC ACID and
electrolytes. Do not
allow battery acid to
contact your skin, eyes,
clothing or paint finish.
Wear eye protection when charging or work-
ing near a battery.
Always provide ventila-
tion when working in an
enclosed space.

✽NOTICE
• When replacing fuse, turn theignition “OFF” and turn off
switches of all electrical devices
then remove 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.
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 the audio system or theft
alarm system, or remote engine
control may cause vehicle dam-
age and increase the risk of 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 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.
(Continued)
(Continued)The electrical system andwiring of the vehicle interiormay be damaged or burneddue to contact failure.
• 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.

Engine compartment fuse
replacement
1. Turn the ignition switch and allother switches off.
2. Remove the fuse panel cover by pressing the tab and pulling the
cover up. When the blade type
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.
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.
CAUTION
After checking the fuse panel inthe engine compartment,securely install the fuse panelcover through the audible click-ing sound.
If not, electrical failures mayoccur from water contact.

✽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.
Main fuse
If the main 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 main 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.
