Vacuum crankcase ventilation
hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to assure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
Air cleaner filter
A Genuine Kia air cleaner filter is
recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Manual transaxle fluid
(if equipped)
Inspect the manual transaxle fluid
according to the maintenance sched-
ule.
Valve clearance (if equipped)
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. An authorized Kia dealer
should perform the operation.

Maintenance
WASHER FLUID
Checking the washer fluid
level
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. Plain water may be used if
washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.
Checking the parking brake
Check the stroke of the parking
brake by counting the number of
“clicks’’ heard while fully applying it
from the released position. Also, the
parking brake alone should securely
hold the vehicle on a fairly steep
grade. If the stroke is more or less
than specified, have the parking
brake adjusted by an authorized Kia
dealer.
Stroke : 6~8 “clicks’’ at a force of 20kg (44 lbs, 196 N).
WARNING- Windshield
fluid
Do not drink the windshield
washer fluid. The windshield
washer fluid is poisonous to
humans and animals.
WARNING- Coolant
Do not use radiator coolant or antifreeze in the washer fluid
reservoir.
Radiator coolant can severely obscure visibility when sprayed
on the windshield and may
cause loss of vehicle control.
WARNING- Flammable
fluid
Do not allow the washer fluid to
come in contact with open
flames or sparks. The windshield
washer fluid reservoir is flamma-
ble under certain circumstances.
This can result in a fire.

BATTERY
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.
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.WARNING- Sulfuric acid
in batteries
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
The actual fuse/relay panel label
may differ depending on equip-
ment/options.
Instrument panel fuse replace-
ment
1. Turn the ignition switch and all
other switches off.
2. Open the fuse panel cover.
CAUTION- Fuse replace- ment
Do not input any other objectsexcept fuses or relays intofuse/relay terminals such as adriver or wiring. It may causecontact failure and system mal-function.

WARNING - Electrical Fire
Always ensure replacements fuses and relays are securely
fastened when installed.
Failure to do so can result in a
vehicle fire.
We recommend that you do not remove fuses, relays and termi-
nals that are fastened with
bolts or nuts. If they are not
completely re-installed, such
looseness may cause electrical
arcing and a possible fire. If
fuses, relays and terminals fas-
tened with bolts or nuts need
replacement, consult with an
authorized Kia dealer.

Maintenance
✽ ✽NOTICE
• If the fuse switch is in the OFF
position, the warning chime,
audio, clock and interior lamps,
etc., will not operate. Some items
must be reset after replacement.
Refer to “Battery” in this chapter.
• Even when the fuse switch is in the OFF position, the battery can still
be discharged by operation of the
headlights or other electrical
devices.
Engine compartment fuse
replacement
1.Turn the ignition switch and all
other switches off.
2.Remove the fuse panel cover by pressing the tab and pulling the
cover up.
When the blade type fuse is dis-
connected, remove it by using the
clip designed for changing fuses
located in the engine room fuse
box. Upon removal, securely insert
reserve fuse of equal quantity. 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.
CAUTION - Fuse panel
covers
After checking the fuse panel inthe engine compartment,securely install the fuse panelcover. If not, electrical failuresmay occur from water contact.
