Maintenance
Fuel tank and fuel cap
The fuel tank and fuel cap should be
inspected at those intervals specified in
the maintenance schedule. Make sure
that a new fuel tank or fuel cap is cor-
rectly replaced.
Vacuum crankcase ventilation
hoses
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
A Genuine Kia air cleaner filter is recom-
mended when the filter is replaced.
Spark plugs
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.

NOTICE
Automatic transmission fluid color is
basically red.
As the vehicle is driven, the automatic
transmission fluid will begin to look

It is normal condition and you should not
judge the need to replace the fluid
based upon the changed color.
CAUTION
Use only specified automatic transmis-
sion fluid. The use of a non-specified
fluid could result in a transmission mal-
function and failure. (Refer to "Recom-
