Maintenance
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
to visit an authorised Kia dealer/service
partner.
Spark plugs (for petrol engine)
Make sure to install new spark plugs of
the correct heat range.
When assembling parts, be sure to wipe
the inside and outside of the boot bot-
tom of the ignition coil and the insulator
of the spark plug with a soft cloth to pre-
vent contamination of the spark plug
insulator.
