EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,more frequent oil and filter changesare required. Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary. Fuel filter A clogged filter can limit the speed at
which the vehicle may be driven,damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently.
After installing a new filter, run the
engine for several minutes, and
check for leaks at the connections.
We recommend that the fuel lines,fuel hoses and connectioner be
replaced by an authorized Kia deal-
er.Fuel lines, fuel hoses and con- nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend that the fuel
lines, fuel hoses and connectionsr be
replaced by an authoized Kia dealer.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapor hose or fuel filler cap is cor-rectly replaced.
CAUTION
When you are inspecting the
belt, place the engine start/stopbutton in the OFF or ACC posi- tion.

Maintenance
Vacuum crankcase ventilation hoses (if equipped)
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 whichmight 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
We recommend that the air cleaner
filter be replaced by an authorized
Kia dealer. Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Valve clearance
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. We recommend that the system
be serviced by an authorized Kia
dealer. 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.
WARNING
Do not disconnect and inspect spark plugs when the engine is
hot. You may burn yourself.

Maintenance
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine
off, check for excessive free-play in
the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or dam-
age. Replace any damaged parts.Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged parts
and, if necessary, repack the grease.
Air conditioning refrigerant (if equipped)
Check the air conditioning lines and
connections for leakage and damage.

ENGINE OIL
Checking the engine oil level
1. Be sure the vehicle is on level ground.
2. Start the engine and allow it to reach normal operating tempera-
ture.
3. Turn the engine off and wait for a few minutes (about 5 minutes) for
the oil to return to the oil pan.
4. Pull the dipstick out, wipe it clean, and re-insert it fully. 5. Pull the dipstick out again and
check the level. The level should
be between F and L.
If it is near or at L, add enough oil to
bring the level to F.Do not overfill.
Use a funnel to help prevent oil
from being spilled on engine com-ponents.
Use only the specified engine oil. (Refer to “Recommended lubricantsand capacities” in section 8.)
WARNING - Radiator
hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may
be hot enough to burn you.
CAUTION
Do not overfill the engine oil. It may damage the engine.
Do not spill engine oil, when adding or changing engine oil.If you drop the engine oil on theengine room, wipe it off imme-diately.
When you wipe the oil level gauge, you should wipe it with aclean cloth. When mixed withdebris, it can cause enginedamage.

Maintenance
Changing the engine oil and filter
We recommend that the engine oil
and filter be replaced by an author-
ized Kia dealer.
WARNING
Used engine oil may cause irri- tation or cancer of the skin if
left in contact with the skin for
prolonged periods of time. Used
engine oil contains chemicals
that have caused cancer in lab-
oratory animals. Always protect
your skin by washing your
hands thoroughly with soapand warm water as soon as pos-
sible after handling used oil.

ENGINE COOLANT
The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, atthe beginning of the winter season,
and before traveling to a colder cli-
mate. Checking the coolant level
WARNING
Removing radiator cap
Never attempt to remove the radiator cap while the engine
is operating or hot. Doing somight lead to cooling system
and engine damage and could
result in serious personal
injury from escaping hotcoolant or steam.
Turn the engine off and wait until it cools down. Use
extreme care when removing
the radiator cap. Wrap a thick
towel around it, and turn it
counterclockwise slowly to
the first stop. Step back while
the pressure is released fromthe cooling system.
(Continued)
(Continued)When you are sure all the pressure has been released,
press down on the cap, using
a thick towel, and continue
turning counterclockwise to
remove it.
Even if the engine is not oper- ating, do not remove the radi-ator cap or the drain plugwhile the engine and radiator
are hot. Hot coolant and
steam may still blow out
under pressure, causing seri-
ous injury.
CAUTION
When the engine overheats
from low engine coolant, sud-denly adding engine coolantmay cause cracks in theengine. To prevent damage, add engine coolant slowly insmall quantities.
Do not drive with no engine coolant. It may cause waterpump failure and engine seizure, etc.

727
Maintenance
Check the condition and connections of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between F and L marks on the side
of the coolant reservoir when theengine is cool.
If the coolant level is low, add enough
distilled (deionized) water. Bring the
level to F (Full) , but do not overfill.
If frequent additions are required, we recommend that the system be
inspected by an authorized Kia dealer.
Recommended engine coolant
When adding coolant, use onlydeionized water or soft water for
your vehicle and never mix hard
water in the coolant filled at the fac-
tory. An improper coolant mixture
can result in serious malfunction or
engine damage.
The engine in your vehicle has alu- minum engine parts and must be
protected by an ethylene-glycol-
based coolant to prevent corrosionand freezing.
DO NOT USE alcohol or methanol coolant or mix them with the spec-ified coolant.
Do not use a solution that contains more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of thesolution.WARNING
The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times operate even when the
engine is not running. Use
extreme caution when working
near the blades of the cooling
fan so that you are not injured
by a rotating fan blades. As theengine coolant temperature
decreases, the electric motor
will automatically shut off. Thisis a normal condition.

For mixture percentage, refer to the
following table. Changing the coolant
We recommend that the coolant be
replaced by an authorized Kia dealer.
WARNING
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 causing serious injury.
CAUTION
Put a thick cloth around the radiator cap before refilling thecoolant in order to prevent thecoolant from overflowing into engine parts such as the gener-ator.
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 or damage to paint
and body trim.
