VEHICLE MAINTENANCE REQUIREMENTS2
F010C01A-AATSpecified Scheduled ProceduresThese are the procedures such as
inspections, adjustments and
replacements that are listed in the
maintenance charts starting on page 5-4.
These procedures must be performed at
the intervals shown in the maintenance
schedule to assure that your warranty
remains in effect. Although it is strongly
recommended that they be performed by
the trained technicians at your Hyundai
dealer, these procedures may be per-
formed at any qualified service facility.
It is suggested that genuine Hyundai
service parts be used for any required
repairs or replacements. Other parts of
equivalent quality such as engine oil,
engine coolant, manual or auto transaxle
oil, brake fluid and so on which are not
supplied by Hyundai Motor Company or its
distributor may be used without affecting
your warranty coverage but you should
always be sure these are equivalent to the
quality of the original Hyundai parts. Your
Owner's Handbook provides further
information about your warranty coverage.
F010A01A-AATService RequirementsTo ensure that you receive the greatest
number of miles of satisfying operation
from your Hyundai, certain maintenance
procedures must be performed. Although
careful design and engineering have
reduced these to a minimum, those that
are required are of the utmost importance.
It is your responsibility to have these main-
tenance procedures performed to comply
with the terms of the warranties covering
your new Hyundai. The Owner's Handbook
supplied with your new vehicle provides
further information about these warranties.
F010B01A-AATMaintenance RequirementsThe maintenance required for your
Hyundai can be divided into three main
areas:
o Specified scheduled procedures
o General checks
o Do-it-yourself maintenance

F060D01A-AATo Fuel Lines, Fuel Hoses and Con-
nectionsCheck the fuel lines, fuel hoses and con-
nections for leakage and damage. Have a
trained technician replace any damaged
or leaking parts immediately.F060B01NF-GATo Drive BeltsInspect all drive belts for evidence of cuts,
cracks, excessive wear or oil saturation
and replace if necessary. Drive belts should
be checked periodically for proper tension.
F060M01A-AATo Engine Oil and FilterThe engine oil and filter should be changed
at the intervals specified in the
maintenance schedule. If the car is being
driven in severe conditions, more frequent
oil and filter changes are required.F060C01A-AATo Fuel FilterA clogged filter can limit the speed at which
the vehicle may be driven, damage the
emission system and cause hard starting.
If an excessive 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.
F060F01A-AATo Vacuum, Crankcase Ventilation
HosesInspect 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.

VEHICLE MAINTENANCE REQUIREMENTS8
F070G02A-AATo Brake FluidCheck brake fluid level in the brake fluid
reservoir. The level should be between
"MIN" and "MAX" marks on the side of the
reservoir. Use only hydraulic brake fluid

damaged parts immediately.
F070E06A-AATo Automatic Transaxle FluidThe fluid level should be in the “HOT”
range of the dipstick, after the engine and
transaxle are at normal operating
temperature. Check the automatic
transaxle fluid level with the engine running
and the transaxle in neutral, with the
parking brake properly applied. Use
HYUNDAI GENUINE ATF SP III, DIAMOND
ATF SP III, SK ATF SP III or other brands
meeting the SP III specification approved
by Hyundai Motor Co. when adding or
changing fluid. Using the wrong ATF may
result in damage to the ATM.

intervals specified in the maintenance
schedule.
F060J01A-AATo Spark PlugsMake sure to install new spark plugs of the
correct heat range.F060H01A-AATo Air Cleaner FilterA Genuine Hyundai air cleaner filter is
recommended when the filter is replaced.F060G01A-AATo Vapor Hose and Fuel Filler CapThe 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
replaced.

to the maintenance schedule.NOTE:If the oil level is low, check for possible
leaks before adding oil. Do not overfill.
F060N02E-AATo Valve ClearanceInspect excessive valve noise and/or
engine vibration and adjust if necessary. A
qualified technician should perform the
operation.

G030C01JM-AATTo Check the Oil Level
Before checking the oil, warm up the engine
to the normal operating temperature and
be sure your car is parked on level ground.
Turn the engine off.
Wait five minutes, then remove the dipstick,
wipe it off, fully reinsert the dipstick and
withdraw it again. Then note the highest
level the oil has reached on the dipstick. It
should be between the upper ("F") and
lower ("L") range.
!
WARNING:
Be very careful not to touch the radiator
hose when checking the engine oil as it
may be hot enough to burn you.

G030C02NF
(2.4L)
(3.3L)
NOTE:o For good fuel economy, SAE 5W-20
(5W-30), ILSAC GF-3 engine oil is
preferred.
o If SAE 5W-20, ILSAC GF-3 engine oil is
not available, a secondary recom-
mended engine oil for corresponding
temperature range can be used. See

1. Remove the oil filler cap by turning it
counter-clockwise.
2. Add oil, then check the level again. Do
not overfill.
3. Replace the cap by turning it clockwise.
The distance between the "F" and "L" marks
is equal to about 1 quart of oil.
CAUTION:
Slowly pour the recommended oil into a
funnel. Do not overfill to avoid damage to
the engine.
WARNING:
Be very careful not to touch the radiator
hose when adding the engine oil as it may
be hot enough to burn you.
If the oil level is close to or below the "L"
mark, add oil until it reaches the "F" mark.
