WARNING
- Refueling
If pressurized fuel sprays out, it can cover your clothes or skin
and subject you to the risk of fire
and burns. Always remove the
fuel cap carefully and slowly. If
the cap is venting fuel or if you
hear a hissing sound, wait until
the condition stops before com-
pletely removing the cap.
Do not "top off" after the nozzle automatically shuts off whenrefueling.
Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an acci-dent.

When the door is opened, or if the engine
is not started within 1 minute, the
tachometer pointer may move slightly in
the ON position with the engine OFF.
This movement is normal and will not
affect the accuracy of the tachometer
once the engine is running.
Engine temperature gauge
This gauge shows the temperature of the
engine coolant when the ignition switchis ON.
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “If the engine overheats” in section 6.
OXM049057/OXM049051L
CAUTION
If the gauge pointer moves beyond
the normal range area toward the“130/H” position, it indicates over-
heating that may damage theengine.
CAUTION
Do not operate the engine within the tachometer's RED ZONE.
This may cause severe engine dam-age.
WARNING
Never remove the radiator cap
when the engine is hot. The enginecoolant is under pressure and
could cause severe burns. Wait
until the engine is cool before
adding coolant to the reservoir.

IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you will experience a loss of
power, or hear loud pinging or knocking,
the engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Place the shift lever in P (automatic transaxle) or Neutral (manual
transaxle) and set the parking brake. If
the air conditioning is on, turn it off.
3. If engine coolant is running out under the vehicle or steam is coming out
from the hood, stop the engine. Do notopen the hood until the coolant has
stopped running or the steaming has
stopped. If there is no visible loss of
engine coolant and no steam, leave
the engine running and check to be
sure the engine cooling fan is operat-
ing. If the fan is not running, turn the
engine off. 4. Check to see if the water pump drive
belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check for
coolant leaking from the radiator,
hoses or under the vehicle. (If the air
conditioning had been in use, it is nor-
mal for cold water to be draining from
it when you stop).
5. If the water pump drive belt is broken or engine coolant is leaking out, stop the engine immediately and call the
nearest authorized KIA dealer for
assistance. 6. If you cannot find the cause of over-
heating, wait until the engine tempera-
ture has returned to normal. Then, ifcoolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. If over-heating happens again, call an author-
ized KIA dealer for assistance.
WARNING
While the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of the
opening and cause serious burns.
CAUTION
Serious loss of coolant indicates there is a leak in the cooling systemand this should be checked as soonas possible by an authorized KIA dealer.

Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap iscorrectly replaced.
Vacuum crankcase ventilation hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. 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 contact with
any heat source, sharp edges or movingcomponent which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage. Air cleaner filter
A Genuine KIA air cleaner filter is recom- mended when the filter is replaced.
Spark plugs (for gasoline engine)
Make sure to install new spark plugs of
the correct heat range.
Valve clearance
(for gasoline engine)
Inspect for excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized KIA dealer should perform
the operation. Cooling system
Check the cooling system components,
such as the 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 maintenance
schedule.
Manual transaxle fluid (if equipped)
Inspect the manual transaxle fluid
according to the maintenance schedule.
Automatic transaxle fluid (if equipped)
Automatic transaxle fluid should not be
checked under normal usage conditions.
But in severe conditions, the fluid should
be changed at an authorized KIA dealerin accordance to the scheduled mainte-
nance at the beginning of this chapter.
✽✽
NOTICE
Automatic transaxle fluid color is basi-
cally red.
As the vehicle is driven, the automatic
transaxle fluid will begin to look darker.
It is normal condition and you should
not judge the need to replace the fluid
based upon the changed color.
CAUTION
The use of a non-specified fluid could result in transaxle malfunc-
tion and failure.
Use only specified automatictransaxle fluid. (Refer to “Recommended lubricants andcapacities” in section 8.)

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 temperature. 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 betweenF 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 frombeing spilled on engine components.
Use only the specified engine oil. (Refer to “Recommended lubricants and capaci-ties” 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.
OXM079005OXM079004
CAUTION
Do not overfill the engine oil. It may damage the engine.
CAUTION - Diesel engine
Overfilling the engine oil may cause
severe dieseling due to churningeffect. It may lead to engine damage
accompanied with abrupt enginespeed increment, combustion noiseand white smoke emission.

Maintenance
Changing the engine oil and filter
Have engine oil and filter changed by an
authorized KIA dealer according to theMaintenance Schedule at the beginningof this section.The high-pressure cooling system has a
reservoir filled with year round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant level at least once a year, at thebeginning of the winter season, and
before traveling to a colder climate.
Checking the coolant level
WARNING
Used engine oil may cause skin irri- tation or cancer if left in contact
with the skin for prolonged periods
of time. Used engine oil contains
chemicals that have caused cancer
in laboratory animals. Always pro-
tect your skin by washing your
hands thoroughly with soap and
warm water as soon as possibleafter handling used oil.
ENGINE COOLANT
WARNING - Removing
radiator cap
Never attempt to remove the radi- ator cap while the engine is oper-
ating or hot. Doing so might leadto cooling system and engine
damage. Also, hot coolant orsteam could cause serious per-
sonal injury.
(Continued)
(Continued)
Turn the engine off and wait untilit 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 from the
cooling system. When you aresure 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 operat- ing, do not remove the radiatorcap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.

Maintenance
Changing the coolant
Have the coolant changed by an author-
ized KIA dealer according to theMaintenance Schedule at the beginningof this section.
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 pres-
sure causing serious injury.
OXM079007
CAUTION
Put a thick cloth around the radiator cap before refilling the coolant in order to prevent the coolant from
overflowing into engine parts suchas the alternator.
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
the paint and body trim.
