OVERHEATING
If your temperature gauge indicates
overheating, if you experience a loss
of power, or if you hear a loud knock-
ing or pinging noise, the engine has
probably overheated. Should any of
these symptoms occur, use the fol-
lowing procedure:
1. Turn on the hazard warning flash-
er, then drive to the nearest safe
location and stop your vehicle; set
the automatic transaxle in P
(Park), or shift the manual
transaxle to N (Neutral) and apply
the parking brake.
2. Make sure the air conditioner is
off.
3. If coolant or steam is boiling out of
the radiator, stop the engine and
call an Authorized Kia Dealer for
assistance.If coolant is not boiling out, allow
the engine to idle and open the
hood to permit the engine to cool
gradually.
If the temperature does not go
down with the engine idling, stop
the engine and allow sufficient
time for it to cool.
4. The coolant level should then be
checked. If the level in the reser-
voir is low, look for leaks at the
radiator hoses and connections,
heater hoses and connections,
radiator, and water pump. If you
find a major leak or another prob-
lem that may have caused the
engine to overheat, do not operate
the engine until it has been cor-
rected. Call an Authorized Kia
Dealer for assistance. If you do not
find a leak or other problem, care-
fully add coolant to the reservoir.
If the engine frequently overheats,
have the cooling system checked
and repaired by an Authorized Kia
Dealer.
WARNING- Removing
radiator cap
Do not remove the radiator cap
when the engine and radiator
are hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause seri-
ous injury.

Connecting jumper cables Jump starting procedure
1. Make sure the booster battery is
12-volt and that its negative termi-
nal is grounded.
2. If the booster battery is in another
vehicle, do not allow the vehicles
to touch.
3. Turn off all unnecessary electrical
loads.
4. Connect the jumper cables in the
exact sequence shown in the previ-
ous illustration. First connect one
end of a jumper cable to the posi-
tive terminal of the discharged bat-
tery (1), then connect the other end
to the positive terminal on the
booster battery (2). Proceed to con-
nect one end of the other jumper
cable to the negative terminal of the
booster battery (3), then the other
end to a solid, stationary, metallic
point (for example, the engine lifting
bracket) away from the battery (4).
Do not connect it 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.
Connect cables in numerical order and disconnect in reverse order.

Do not allow the jumper cables to
contact anything except the cor-
rect battery terminals or the cor-
rect ground. Do not lean over the
battery when making connections.
5. Start the engine of the vehicle with
the booster battery and let it run at
2,000 rpm, then start the engine of
the vehicle with the discharged
battery.
If the cause of your battery discharg-
ing is not apparent, you should have
your vehicle checked by an
Authorized Kia Dealer.
Refer to illustration on page 6-10.
Push-starting
Your manual transaxle-equipped
vehicle should not be push-started
because it might damage the emis-
sion control system.
Vehicles equipped with automatic
transaxle cannot be push-started.
Follow the directions in this section
for jump-starting.
CAUTION
Never tow a vehicle to start it
because the sudden surge for-
ward when the engine starts
could cause a collision with the
tow vehicle.

ELECTRICAL CIRCUIT PROTECTION
Fuses
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.This vehicle has two fuse panels,
one located in the driver's side knee
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 be melted.
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 fusible link for high-
er amperage ratings.

Fuse replacement
Driver-side knee bolster
1. Turn the ignition switch and all
other switches off.
2. Pull the suspected fuse straight
out. Use the removal tool provided
on the cover.
3. Check the removed fuse; replace it
if it is blown.
Spare fuses are provided in the
fuse panel in engine compart-
ment.
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 audio fuse.
If the headlights or other electrical
components do not work and the
fuses are OK, check the fuse block in
the engine compartment. If a fuse is
blown, it must be replaced.
1LDA40031LDN4022
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 instead 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 dam-
age the system.

Memory fuse
Your vehicle is equipped with a mem-
ory fuse to prevent battery discharge
if your vehicle is parked without
being operated for prolonged peri-
ods. Use the following procedures
before parking the vehicle for pro-
longed period.1. Turn off the engine.
2. Turn off the headlights and tail
lights.
3. Open the driver-side knee bolster
cover and pull up the “ROOM
15A”.
✽
NOTICE
• If the memory fuse is pulled up
from the fuse panel, the warning
chime, audio, clock and intetrior
lamps, etc., will not operate. Some
items must be reset after replace-
ment. (Refer to “Items to be
reset···.” on page 7-26)
• Even though the memory fuse is
pulled up, the battery can still be
discharged by operation of the
headlights or other electrical
devices.
