7EXPLANATION OF SCHEDULED
MAINTENANCE ITEMS
F060F01A-AATo Vacuum, Crankcase
Ventilation Hoses
Inspect the surface of hoses for evidence of
heat and/or mechanical damage. 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 damage.
F060D01A-AAT
o Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and connec-
tions for leakage and damage. Have a trained
technician replace any damaged or leaking
parts immediately.
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.
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.
F060H01A-AATo Air cleaner filter
A Genuine Hyundai air cleaner filter is recom-
mended when the filter is replaced.
F060J01A-AATo Spark plugs
Make sure to install new spark plugs of the
correct heat range.
F060N02E-AAT
o Valve Clearance
Inspect excessive valve noise and/or engine
vibration and adjust if necessary. A qualified
technician should perform the operation.

11WINDSHIELD WIPER BLADES
!CAUTION:o Do not operate the wipers on dry glass.
This can result in more rapid wear of the
wiper blades and may scratch the glass.
o Keep the blade rubber out of contact
with petroleum products such as engine
oil, gasoline, etc.
G080A02A-AAT
The wiper blades should be carefully inspected
from time to time and cleaned to remove accu-
mulations of road film or other debris. To clean
the wiper blades and arms, use a clean sponge
or cloth with a mild soap or detergent and water.
If the wipers continue to streak or smear the
glass, replace them with Genuine Hyundai
Replacement Parts or their equivalent.

CHANGING THE AIR CLEANER
FILTER
G070A01S-AAT
To change the filter, unsnap the clips around the
cover. When this is done, the cover can be lifted
off, the old filter removed and the new filter put
in its place. Genuine Hyundai Replacement
Parts are recommended.
