F060D01A-AATo Fuel Lines, Fuel Hoses and Connec-
tionsCheck the fuel lines, fuel hoses and connec-
tions for leakage and damage. Have a trained
technician replace any damaged or leaking
parts immediately.
F060A01A-AAT F060B01A-AAT
o 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
adjusted as necessary.
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.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 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.
F060F01O-AATo Vacuum 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
F070D01A-AATo Manual Transaxle OilInspect the manual transaxle oil according to
the maintenance schedule.NOTE:If the oil level is low, check for possible leaks
before adding oil. Do not overfill.F070F01A-AATo Brake Hoses and LinesVisually check for proper installation, chafing,
cracks, deterioration and any leakage. Replace
any deteriorated or damaged parts immedi-
ately.
F070C01A-AATo CoolantThe coolant should be changed at the intervals
specified in the maintenance schedule.F060E01A-AATo Timing BeltInspect all parts related to the timing belt for
damage and deformation. Replace any dam-
aged parts immediately.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 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.F065F01O-AATo Crankcase Ventilation HoseInspect the surface of hose 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 that
hose surface nearest to high heat sources,
such as the exhaust manifold.
Inspect the hose routing to assure that the hose
does not come in contact with any heat source,
sharp edges or moving component which might
cause heat damage or mechanical wear. In-
spect all hose connections, such as clamps and
couplings, to make sure they are secure, and
that no leaks are present. Hose should be
replaced immediately if there is any evidence of
deterioration or damage.
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.

WARNING:
The cooling fan is controlled by engine
coolant temperature and may sometimes
operate even when the engine is not run-
ning. Use extreme caution when working
near the blades of the coolant fan so that
you are not injured by a rotating fan blade.
As the engine coolant temperature de-
creases, the fan will automatically shut off.
This is a normal condition. 2. 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 counterclock-
wise.
3. 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.
4. 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.
5. Fill the radiator with clean demineralized or
distilled water. Continue to add clean dem-
ineralized or distilled water in small quantities
until the fluid level stays up in the radiator
neck.6. Start the engine, top off the radiator with
water and then add coolant to the reservoir
until the level is between "L" and "F".
7. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.
G050D02A-AATTo Change the Engine CoolantThe engine coolant should be changed at those
intervals specified in the vehicle maintenance
schedule in Section 5.
HJM5034G050D01JM
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 park-
ing brake and remove the radiator cap when
cool.

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 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
changing color.
You must replace the automatic transaxle
fluid in accordance with intervals specified
in the vehicle maintenance schedule in
section 5.
G100B01L
!
G100B02A-AATTo Check the Manual Transaxle Fluid
Level
WARNING:
It is always better to check the transaxle oil
level when the engine is cool or cold. If the
engine is hot, you should exercise great
caution to avoid burning yourself on hot
engine or exhaust parts.
Park the car on level ground with the engine off.
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.
