In case of an emergency
4. The coolant level should then be
checked. If the level in the reservoir 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 anoth-
er problem that may have caused the
engine to overheat, do not operate the
engine until it has been corrected. Call
an authorized Kia dealer for assis-
tance. If you do not find a leak or other
problem, carefully add coolant to the
reservoir.If the engine frequently overheats, have
the cooling system checked and repaired
by an authorized Kia dealer.
Jump starting Jump starting can be dangerous if done
incorrectly. Therefore, to avoid harm to
yourself or damage to your vehicle or
battery, follow the jump starting proce-
dures. If in doubt, we strongly recom-
mend that you have a competent techni-
cian or towing service jump start your
vehicle.✽ ✽
NOTICEUse only a 12-volt jumper system. You
can damage a 12-volt starting motor,
ignition system, and other electrical
parts beyond repair by use of a 24-volt
power supply (either two 12-volt batter-
ies in series or a 24-volt motor generator
set).
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 serious injury.
EMERGENCY STARTING
WARNING
- Battery
• Keep all flames or sparks away
from the battery. The battery pro-
duces hydrogen gas which may
explode if exposed to flame or
sparks.
 Do not attempt to jump start the
vehicle if the discharged battery
is frozen or if the electrolyte level
is low; the battery may rupture or
explode.
WARNING
- Battery
Never attempt to check the elec-
trolyte level of the battery as this
may cause the battery to rupture or
explode causing serious injury.

In case of an emergency4 6Connecting jumper cables Jump starting procedure
1. Make sure the booster battery is 12-
volt and that its negative terminal 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. Remove the engine cover.
5. Connect the jumper cables in the exact
sequence shown in the previous illus-
tration. First connect one end of a
jumper cable to the positive terminal of
the discharged battery (
1), then con-
nect the other end to the positive ter-
minal on the booster battery (
2).
6. Proceed to connect one end of the
other jumper cable to the negative ter-
minal 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 termi-
nal of the discharged battery.
Connect cables in numerical order and disconnect in reverse order.

In case of an emergency
Do not allow the jumper cables to con-
tact anything except the correct bat-
tery terminals or the correct ground.
Do not lean over the battery when
making connections.
7. Start the engine of the vehicle with the
booster battery and let it run at 2,000
rpm, then start the engine of the vehi-
cle with the discharged battery.If the cause of your battery discharging is
not apparent, you should have your vehi-
cle checked by an authorized Kia dealer.
Push-starting Your manual transaxle-equipped vehicle
should not be push-started because it
might damage the emission control sys-
tem.
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 forward
when the engine starts could cause
a collision with the tow vehicle.
CAUTION -
Battery cables
Do not connect the jumper cable
from the negative terminal of the
booster battery to the negative ter-
minal of the discharged battery.
This can cause the discharged bat-
tery to overheat and crack, releas-
ing battery acid.

In case of an emergency6 6ELECTRICAL CIRCUIT PROTECTIONFuses A 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 panel bolster,
the other in the engine compartment
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 indi-
cates 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 high-
er amperage ratings.
Fuse replacement ✽ ✽
NOTICEDo not use a screwdriver or any other
metal object to remove fuses because it
may cause a short circuit and damage
the system.
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 through overheat-
ing 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.

In case of an emergency
Driver-side panel bolster1. Turn the ignition switch and all other
switches off.
2. Open the cover.3. Pull the suspected fuse straight out.
Use the removal tool (1) provided in
the engine compartment fuse/relay
box.
4. Check the removed fuse; replace it if it
is blown.
Spare fuses are provided in the 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 circuit you may
not need for operating the vehicle, such
as the audio fuse.If the headlights or other electrical com-
ponents 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.

In case of an emergency8 6Engine compartment1. Turn the ignition switch and all other
switches off.
2. Remove the fuse box cover by press-
ing the taps and pulling up.
3. Check the removed fuse; replace it if it
is blown.
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.
✽ ✽
NOTICEAfter checking the fuse box in the engine
compartment, securely install the fuse
box cover. If not, electrical failures may
occur from water leaking in.
Main fuse
If the MAIN fuse is blown, it must be
removed as follows:
1. Disconnect the negative battery cable.
2. Remove the nuts shown in the picture
above.
3. Replace the fuse with a new one of the
same rating.
4. Reinstall in the reverse order of
removal.✽ ✽
NOTICEIf the MAIN fuse is blown, consult an
authorized Kia dealer.

fuses to prevent battery discharge if your
vehicle is parked without being operated
for prolonged periods. Use the following
procedures before parking the vehicle for
prolonged 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 “MEMORY 15A /
AUDIO 15A”.
✽ ✽
NOTICE• If the memory fuses are pulled up
from the fuse panel, the warning
chime, audio, clock and interior
lamps, etc., will not operate. Some
items must be reset after replacement.
• Even though the memory fuses are
pulled up, the battery can still be dis-
charged by operation of the head-
lights or other electrical devices.
