EXPLANATION OF SCHEDULED
MAINTENANCE ITEMS
F060D01A-AATo Fuel Lines, Fuel Hoses and
ConnectionsCheck the fuel lines, fuel hoses and connec-
tions for leakage and damage. Have a trained
techincian, replace any damaged or leaking
parts immediately.
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 techni-
cians.F060M01A-AATo Engine Oil and FilterThe 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.
F060H01A-AATo Air Cleaner FilterA Genuine Hyundai air cleaner filter is recom-
mended 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 re-
placed.
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. Par-
ticular 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.
F060B01A-AATo 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 and ad-
justed as necessary.F060J01A-AATo Spark PlugsMake sure to install new spark plugs of the
correct heat range.

G050D02A-AATTo Change the CoolantThe coolant should be changed at those inter-
vals specified in the vehicle maintenance sched-
ule in Section 5.
CAUTION:
Engine coolant can damage the finish of
your car. If you spill engine coolant on the
car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the parking
brake and remove the radiator cap when
cool.
2. Be sure your drain receptacle is in place.
Open the drain cock on the radiator. Allow all
the engine coolant to drain from the cooling
system, then securely close the drain cock.
3. Check Section 9 for the capacity of the
cooling system in your car. Then, following
the manufacturer's directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator.
!
4. Turn the radiator cap counterclockwise with-
out pressing down on it, until it stops. This
relieves any pressure remaining in the cool-
ing system. And remove the radiator cap by
pushing down and turning counterclockwise.
Now fill the radiator with clean demineralized
or distilled water. Continue to add clean
demineralized or distilled water in small quan-
tities until the fluid level stays up in the
radiator neck.
G050D01AG050D02A
5. Start the engine, top off the radiator with
water and then add engine coolant to the
reservoir until the level is between "L" and
"F".
6. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.

CHECKING THE TRANSAXLE
FLUID (AUTOMATIC)
!
G110A01E-AATTransaxle fluid in the automatic transaxle should
be checked at those intervals specified in the
vehicle maintenance schedule in Section 5.NOTE:Automatic transaxle fluid is basically a red
color. As driving distance increases, the fluid
color turns darkish red gradually. It is a
normal condition and you should not judge
the need to replace based upon the chang-
ing color.
You must replace the automatic transaxle
fluid in accordance with intervals specified
in the vehicle maintenance schedule in sec-
tion 5.
G110C02A-AATTransaxle Fluid CapacityThe fluid capacity of the automatic transaxle is
6.45 U.S. quarts (6.1 liters).
WARNING:
The transaxle fluid level should be checked
when the engine is at normal operating tem-
perature. This means that the engine, radia-
tor, exhaust system etc., are very hot. Exer-
cise great care not to burn yourself during
this procedure. 1. Using a wrench of the correct size, loosen
the oil filler plug by turning it counterclock-
wise and remove it with your fingers.
2. Use your finger or suitable tool to feel inside
the hole. The oil level should be at its bottom
edge. If it is not, check for leaks before
adding oil. To refill the transaxle or bring the
oil level up, add oil slowly until it reaches the
proper level. Do not overfill.
3. Replace the plug and washer, screw it in with
your fingers and then tighten securely with
the wrench.
!
G110B05A-AATRecommended FluidYour Hyundai automatic transaxle is specially
designed to operate with HYUNDAI GENUINE
ATF SP III, DIAMOND ATF SP III, SK ATF SP
III or other brands meeting the SP III specifi-
cation approved by Hyundai Motor Co..
Damage caused by a nonspecified fluid is not
covered by your new vehicle limited warranty.
CAUTION:
Use of aftermarket ATF additives may
cause damage to the automatic transaxle.
Only 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.. If you are
having your vehicle serviced at a facility
other than a Hyundai dealer, verify that the
correct ATF is used for your vehicle.
