Explanation of scheduled
maintenance items
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the vehicle is
being driven in severe conditions, more
frequent oil and filter changes are
required.
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.
CAUTION
When you are inspecting the belt, place
the ignition switch in the LOCK/OFF or
ACC position.
Fuel filter (for petrol)
Kia petrol vehicles are equipped with a
lifetime fuel filter that integrated with
the fuel tank. Regular maintenance or
replacement is not needed but depends
on fuel quality. If there are some import
-
ant safety matters like fuel flow restric
-
tion, surging, loss of power, hard starting
problem etc, fuel filter inspection or
replace is needed.
Have the fuel filter inspected or replaced
by a professional workshop. Kia recom
-
mends to visit an authorised Kia dealer/
service partner.
Fuel lines, fuel hoses and connec
-
tions
Check the fuel lines, fuel hoses and con
-
nections for leakage and damage. Have
the fuel lines, fuel hoses and connec
-
tions replaced by a professional work

shop. Kia recommends to visit an
authorised Kia dealer/service partner.
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those intervals
specified in the maintenance schedule.
Make sure that a new vapour 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. 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
damage or mechanical wear. Inspect all
hose connections, such as clamps and
couplings, 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 dam
-
age.
Air cleaner filter
Have the air cleaner filter replaced by a
professional workshop. Kia recommends
