EXPLANATION OF SCHEDULED MAIN-
TENANCE ITEMS
F060M01A-AAT
o Engine Oil and Filter
The engine oil and filter should be changed at
the intervals specified in the maintenance sched-
ule. If the car is being driven in severe condi-
tions, more frequent oil and filter changes are
required.
F060C01A-AAT
o Fuel Filter
A clogged filter can limit the speed at which the
vehicle may be driven, damage the emission
system and cause hard starting. If an exces-
sive amount of foreign matter accumulates in
the fuel tank, the filter may require replacement
more frequently.
After installing a new filter, run the engine for
several minutes, and check for leaks at the
connections. Fuel filters should be installed by
trained technicians.
F060B01A-AAT
o Drive Belts
Inspect all drive belts for evidence of cuts,
cracks, excessive wear or oil and replace if
necessary. Drive belts should be checked pe-
riodically for proper tension and adjusted as
necessary.

VEHICLE MAINTENANCE REQUIREMENTS
F060D01A-AAT
o Fuel Lines, Fuel Hoses and Connec-
tions
Check the fuel lines, fuel hoses and connec-
tions for leakage and damage. Have a trained
technician replace any damaged or leaking parts
immediately.
F060F01A-AAT
o Vacuum, Crankcase
Ventilation Hoses
Inspect the surface of hoses for evidence of
heat and/or mechanical damage. Hard and brit-
tle rubber, cracking, tears, cuts, abrasions, and
excessive swelling indicate deterioration. Par-
ticular attention should be paid to examine
those hose surfaces nearest to high heat sourc-
es, 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 damage.
F060G01A-AAT
o 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 re-
placed.

o Air cleaner filter
A Genuine Hyundai air cleaner filter is recom-
mended when filter is replaced.
F060J01A-AAT
o Spark plugs
Make sure to install new spark plugs of the
correct heat range.

o Timing belt
Inspect all parts related to the timing belt for
damage and deformation. Replace any dam-
aged parts immediately.

ule.
