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.
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 spark
plugs when the engine is hot. You
may burn yourself.
Valve clearance (for gasoline
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.
Dual clutch transmission fluid (if
equipped)
Inspect the dual clutch transmission
fluid according to the maintenance
schedule.
Automatic transaxle fluid (if

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.
