EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
G050100AUN
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 fre-
quent oil and filter changes are required.
G050200AUN
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil satu-
ration and replace if necessary. Drive
belts should be checked periodically for
proper tension and adjusted as neces-
sary.
G050300AUN
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 exces-
sive amount of foreign matter accumu-
lates 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. Fuel filters should be
installed by an authorized KIA dealer.
G050400AUN-EU
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. Have
an authorized KIA dealer replace any
damaged or leaking parts immediately.
G050600AUN
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 is
correctly replaced.

Maintenance
G050700AUN
Vacuum crankcase ventilation
hoses
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 moving
component 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.
G050800AUN
Air cleaner filter
A Genuine KIA air cleaner filter is recom-
mended when the filter is replaced.
G050900AUN
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 necessary.
An authorized KIA dealer should perform
the operation.
G051100AUN
Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.

Changing the engine oil and filter
Have engine oil and filter changed by an
authorized KIA dealer according to the
Maintenance Schedule at the beginning
of this section.
G070000AUN
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 the
beginning of the winter season, and
before traveling to a colder climate.

Checking the coolant level
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 lead
to cooling system and engine
damage and could result in seri-
ous personal injury from escap-
ing hot coolant or steam.
(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 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 operat- ing, do not remove the radiator
cap 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.
WARNING
Used engine oil may cause irrita-
tion 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 laboratory ani-
mals. Always protect your skin by
washing your hands thoroughly
with soap and warm water as soon
as possible after handling used oil.

Changing the coolant
Have coolant changed by an authorized
KIA dealer according to the Maintenance
Schedule at the beginning of 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.
CAUTION
Put a thick cloth or fabric around
the radiator cap before refilling thecoolant in order to prevent the coolant from overflowing intoengine parts such as the generator.
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.

✽
✽
NOTICE
“C” (COLD) range is for reference only
and should NOT be used to determine
transaxle fluid level.
✽ ✽NOTICE
New automatic transaxle fluid should be
red. The red dye is added so the assem-
bly plant can identify it as automatic
transaxle fluid and distinguish it from
engine oil or antifreeze. The red dye,
which is not an indicator of fluid quali-
ty, is not permanent. As the vehicle is
driven, the automatic transaxle fluid
will begin to look darker. The color may
eventually appear light brown.
Therefore, have an authorized KIA
dealer change the automatic transaxle
fluid according to the Scheduled
Maintenance at the beginning of this
section.
Use only the specified automatic
transaxle fluid. (Refer to “Recommended
lubricants and capacities” in section 8.)
G100200AUN
Changing the automatic transaxle
fluid
Have automatic transaxle fluid changed
by an authorized KIA dealer according to
the Maintenance Schedule at the begin-
ning of this section.
WARNING - Transaxle fluid
The transaxle fluid level should be
checked when the engine is at nor-
mal operating temperature. This
means that the engine, radiator,
radiator hose and exhaust system
etc., are very hot. Exercise great
care not to burn yourself during
this procedure.
WARNING- Parking brake
To avoid sudden movement of the
vehicle, apply parking brake and
depress the brake pedal before
moving the shift lever.
CAUTION
Low fluid level causes transaxle
slippage. Overfilling can causefoaming, loss of fluid and transaxlemalfunction.
The use of a non-specified fluid could result in transaxle malfunc-tion and failure.

should not be cleaned and reused. Replace the filter according to the
Maintenance Schedule.
If the vehicle is operated in extremely
dusty or sandy areas, replace the ele-ment more often than the usual recom-mended intervals.
G170100AUN-EC
Filter inspection
If the vehicle is operated in severely air-
polluted cities or on dusty rough roads for
a long period, it should be inspected
more frequently and replaced earlier.
When you replace the climate control air
filter, replace it performing the following
procedure, and be careful to avoid dam-
aging other components.
OMG075012

EMISSION CONTROL SYSTEM
G270000AUN-EU
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty infor-
mation contained in the Owner’s
Handbook & Warranty Information book-
let in your vehicle.
Your vehicle is equipped with an emis-
sion control system to meet all applicable
emission regulations.
There are three emission control sys-
tems, as follows.
(1) Crankcase emission control system
(2) Evaporative emission control system
(3) Exhaust emission control system
In order to assure the proper function of
the emission control systems, it is rec-
ommended that you have your car
inspected and maintained by an author-
ized KIA dealer in accordance with the
maintenance schedule in this manual. Caution for the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
To prevent the vehicle from misfir-
ing during dynamometer testing,
turn the Electronic Stability Control
(ESC) system off by pressing the
ESC switch.
After dynamometer testing is com- pleted, turn the ESC system back on
by pressing the ESC switch again.
G270100AUN
1. Crankcase emission control system
The positive crankcase ventilation sys-
tem is employed to prevent air pollution
caused by blow-by gases being emitted
from the crankcase. This system supplies
fresh filtered air to the crankcase through
the air intake hose. Inside the crankcase,
the fresh air mixes with blow-by gases,
which then pass through the PCV valve
into the induction system.
G270200AFD
2. Evaporative emission control
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.
