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.
Hoses should be replaced immediately
if there is any evidence of deterioration
or damage.
Air cleaner filter
We recommend that the air cleaner fil‐
ter be replaced by an authorized Kia
dealer.
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) (Except for Nu 2.0
Engine)
Inspect for excessive valve noise and/or
engine vibration and adjust if necessa‐
ry. We recommend that the system be
serviced by an authorized Kia dealer.
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
equipped)
Automatic transaxle fluid should not be
checked under normal usage conditions.
We recommend that the automatic
transmission fluid changed by an au‐
thorized Kia dealer according to the
maintenance schedule.
