Vapor hose (for gasoline engine)
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.
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evi‐
dence of heat and/or mechanical dam‐ age. Hard and brittle rubber, cracking,
tears, cuts, abrasions, and excessive
swelling indicate deterioration. Particu‐ lar 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 mov‐ ing component which might cause heat
damage or mechanical wear. Inspect all
hose connections, such as clamps and couplings, to make sure they are se‐
cure, and that no leaks are present. Ho‐
ses should be replaced immediately if there is any evidence of deterioration
or damage.
Air cleaner filter
Have the air cleaner filter replaced by a
professional workshop. Kia recom‐ mends to visit an authorized Kia dealer/
service partner.
Spark plugs (for gasoline engine)
Make sure to install new spark plugs of
the correct heat range.
WARNING
Do not disconnect and inspect sparkplugs when the engine is hot. Youmay burn yourself.
Valve clearance (for Kappa 1.0L
T-GDI engine)
Inspect for excessive valve noise and/or
engine vibration and adjust if necessa‐ ry. In this case, have the system serv‐
iced by a professional workshop. Kia
recommends to visit an authorized Kia dealer/service partner.
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 ac‐
cording to the maintenance schedule.
Automatic transaxle fluid (if
equipped)
Automatic transaxle fluid should not be
checked under normal usage conditions.
Have the automatic transmission fluid changed by a professional workshop
according to the maintenance schedule.
Kia recommends to visit an authorized Kia dealer/service partner.
NOTICE
Automatic transaxle fluid color is ba‐
sically red.
As the vehicle is driven, the auto‐
matic transaxle fluid will begin to
look darker. It is normal condition
and you should not judge the need

CAUTION
•Do not overfill the engine oil. Itmay damage the engine.
•Do not spill engine oil, when add‐ing or changing engine oil. If youdrop the engine oil on the engineroom, wipe it off immediately.
•When you wipe the oil levelgauge, you should wipe it with aclean cloth. When mixed withdebris, it can cause engine dam‐age.

WARNING
Used engine oil may cause skin irri‐tation or cancer if left in contactwith the skin for prolonged periodsof time. Used engine oil containschemicals that have caused cancer inlaboratory animals. Always protectyour skin by washing your handsthoroughly with soap and warm wa‐ter as soon as possible after han‐dling used oil.

ENGINE COOLANT
The high-pressure cooling system has
a reservoir filled with year round anti‐
freeze coolant. The reservoir is filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at the
beginning of the winter season, and be‐ fore traveling to a colder climate.
CAUTION
•When the engine overheats fromlow engine coolant, suddenly add‐ing engine coolant may causecracks in the engine. To preventdamage, add engine coolant slowlyin small quantities.
•Do not drive with no engine cool‐ant. It may cause water pump fail‐ure and engine seizure, etc.
Checking the coolant level
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 dam‐age. Also, hot coolant or steamcould cause serious personal in‐jury.
•Turn the engine off and wait untilit cools down. Use extreme carewhen removing the radiator cap.Wrap a thick towel around it, andturn it counterclockwise slowly tothe first stop. Step back while thepressure is released from the cool‐ing system.When you are sure all the pressurehas been released, press down onthe cap, using a thick towel, andcontinue turning counterclockwiseto remove it.
(Continued)
(Continued)
•Even if the engine is not operating,do not remove the radiator cap orthe drain plug while the engine andradiator are hot. Hot coolant andsteam may still blow out underpressure, causing serious injury.
WARNING
The electric motor (cool‐ing fan) is controlled byengine coolant tempera‐ture, refrigerant pressureand vehicle speed.
It may sometimes operate evenwhen the engine is not running. Useextreme caution when working nearthe blades of the cooling fan so thatyou are not injured by a rotating fanblades. As the engine coolant tem‐perature decreases, the electric mo‐tor will automatically shut off. Thisis a normal condition.

Check the condition and connections of
all cooling system hoses and heater ho‐ ses. Replace any swollen or deteriora‐
ted hoses.
The coolant level should be filled be‐
tween MAX and MIN (F and L) marks on the side of the coolant reservoir when
the engine is cool.
If the coolant level is low, add enough
distilled (deionized) or soft water. Bring the level to MAX (F), but do not overfill.
If frequent additions are required, have
the system inspected by a professional
workshop. Kia recommends to visit an authorized Kia dealer/service partner.
Recommended engine coolant
• When adding coolant, use only deion‐ ized water or soft water for your ve‐
hicle and never mix hard water in the
coolant filled at the factory. An im‐
proper coolant mixture can result in serious malfunction or engine dam‐
age.
• The engine in your vehicle has alumi‐ num engine parts and must be pro‐
tected by an ethylene-glycol with
phosphate based coolant to prevent corrosion and freezing.
• DO NOT USE alcohol or methanol coolant or mix them with the speci‐
fied coolant.
• Do not use a solution that contains more than 60% antifreeze or lessthan 35% antifreeze, which would re‐
duce the effectiveness of the solu‐
tion.
For mixture percentage, refer to the
following table.

WARNING
Radiator cap
Do not remove the radiator capwhen the engine and radiator arehot. Scalding hot coolant and steammay blow out under pressure caus‐ing serious injury.
Maintenance

Changing the coolant
Have the coolant replaced by a profes‐
sional workshop. Kia recommends to visit an authorized Kia dealer/service
partner.
CAUTION
Put a thick cloth around the radiatorcap before refilling the coolant in or‐der to prevent the coolant fromoverflowing into engine parts suchas the alternator.
WARNING
nCoolant
•Do not use radiator coolant or an‐tifreeze in the washer fluid reser‐voir.
•Radiator coolant can severely ob‐scure visibility when sprayed onthe windshield and may cause lossof vehicle control or damage thepaint and body trim.

AUTOMATIC TRANSAXLE FLUID (IF EQUIPPED)
Checking the automatic
transaxle fluid level
The automatic transaxle fluid level
should be checked regularly.
Keep the vehicle on level ground with the parking brake applied and check the
fluid level according to the following
procedure. 1. Place the shift lever in N (Neutral) position and confirm if the engine is
running at normal idle speed.
NOTICE
Insert the level gauge, after checking
the automatic transaxle fluid level. In
the direction referred in the picture.
CAUTION
If you insert the level gauge in thewrong direction, it can cause defor‐mation (or damage) to level gauge.
2. After the transaxle is warmed up sufficiently [fluid temperature
70~80°C (158~176°F)], for example
by 10 minutes usual driving, move
the shift lever through all positions
then place the shift lever in N(Neu‐
tral) or P(Park) position.

3. Confirm if the fluid level is in the "HOT" range on the level gauge. If
the fluid level is lower, add the
specified fluid from the fill hole. If
the fluid level is higher, drain the
fluid from the drain hole.
4. If the fluid level is checked in cold condition [fluid temperature
20~30°C (68~86°F)], add the fluid to
the "COLD" line and then recheck the fluid level according to the
above step 2.
