4. Turn off all unnecessary electrical
loads.
5. Connect the jumper cables in the exact
sequence shown in the illustration on
the previous page.
First, connect one end of a jumper
cable to the positive terminal (+) of
the discharged battery , then the
other end of the same cable to the
positive terminal (+) on the booster
battery, . Next, connect one end of
the other jumper cable to the negative
terminal (-) of the booster battery ,
then the other end to a solid,
stationary, metallic point (for
example, the engine lifting bracket) 
away from the battery. Do not connect
the jumper cable to or near any part
that moves when the engine is
cranked. Do not connect the jumper
cable from the negative terminal (-) of
the booster battery to the negative
terminal (-) of the discharged battery.Do not allow the jumper cables to
contact anything except the correct
battery terminals or the correct
ground. Do not lean over the battery
when making connections.
6. Start the engine of the vehicle with
the booster battery and run it at 2,000
rpm. Then, start the engine of the
vehicle with the discharged battery.
If the cause of your battery discharging
is not apparent (for example, having left
the lights on accidentally), you should
have your vehicle checked by an
Authorized Kia Dealer.
PUSH-STARTINGA vehicle equipped with an automatic
transaxle cannot be started by pushing. A
vehicle equipped with a manual transaxle
should not be push-started because it
could damage the emission control
system. Follow the directions for jump
starting.
IN CASE OF EMERGENCY

CAUTION
Never tow a vehicle to start it. A
sudden surge forward when the
engine starts could cause a collision
with the tow vehicle.

ELECTRICAL CIRCUIT
PROTECTIONFUSESA vehicle’s electrical system is protected
from electrical overload damage by fuses.
This vehicle has two fuse panels, one
located in the driver’s side kick panel, the
other in the engine compartment near the
battery. A fuse panel chart is provided
later in this section.If any of your vehicle’s lights,
accessories, or controls do not work,
check the appropriate circuit fuse. If a
fuse has blown, the element inside the
fuse will be melted. Always replace a
blown fuse with one of the same rating.
If the replacement fuse blows out, this
indicates an electrical problem. Avoid
using the system involved and
immediately consult an Authorized Kia
Dealer.
Two kinds of fuses are used: standard for
lower amperage rating, and main for
higher amperage ratings.
FUSE REPLACEMENTIf the electrical system does not work,
first check the driver’s side fuse panel.

WARNING - Fuse
Replacement
 Never replace a fuse with
anything but another fuse of
the same type and rating.
 A higher capacity fuse could
cause damage and possibly
a fire.
 Never install a wire in place
of the proper fuse - even as a
temporary repair. It may
cause extensive wiring
damage and possibly a fire.
 Do not use a screwdriver or
any other metal object to
remove fuses because it may
cause a short circuit and
damage the system.

1. Turn the ignition switch and all other
switches off.
2. Pull the suspected fuse straight out.
Use the removal tool provided on the
main fuse box in the engine
compartment. Refer to the fuse panel
chart on the fuse panel cover to
identify the likely problem fuse or
electrical circuit.
3. Check the removed fuse; replace if it
is blown.
Four (4) spare fuses are provided in the
engine compartment fuse panel cover.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.
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 radio or clock (Room) fuse.
If the headlights or other electrical
components do not work and the fuses
are OK, check the fuse box in the engine
compartment. If a fuse is blown, it must
be replaced.
1. Turn the ignition switch and all other
switches OFF.
2. Remove the fuse box cover by
turning the plastic knob located in the
cover counterclockwise until the
cover can be removed.
3. Check the fuses. If one is blown,
replace it with a new one of the same
rating.
