F060H01A-AAT
o Air Cleaner Filter A Genuine Hyundai air cleaner filter is
recommended when the filter is re- placed. F060J01A-AAT
o Spark Plugs Make sure to install new spark plugs of the correct heat range. F070B01A-GAT
o Cooling System Check the cooling system part, such as radiator, coolant reservoir, hosesand connections for leakage and dam- age. Replace any damaged parts.
F060E01A-AAT
o Timing Belt
Inspect all parts related to the timing belt for damage and deformation. Replace any damaged parts immedi- ately. F060G01A-AAT
o Vapor Hose and Fuel Filler Cap
The vapor hose and fuel filler cap should be inspected at those inter- vals specified in the maintenanceschedule. Make sure that a new va- por hose or fuel filler cap is correctly replaced. F060F01A-AAT
o Vacuum, Crankcase Ventila-
tion Hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical dam- age. Hard and brittle rubber, crack- ing, tears, cuts, abrasions, and ex-cessive swelling indicate deteriora- tion. Particular attention should be paid to examine those hose surfacesnearest to high heat sources, such as the exhaust manifold.
Inspect the hose routing to assure that
the hoses do not come in contact withany heat source, sharp edges or mov- ing component which might cause heatdamage or mechanical wear. Inspect all hose connections, such as clamps and couplings, to make sure they aresecure, and that no leaks are present. Hoses should be replaced immedi- ately if there is any evidence of dete-rioration or damage. F060N02E-GAT
o Valve Clearance
Inspect excessive valve noise and/or engine vibration and adjust if neces- sary. A qualified technician shouldperform the operation.

4. Turn the radiator cap counterclock-
wise without pressing down on it, until it stops. This relieves any pres- sure remaining in the cooling sys- tem. And remove the radiator cap by pushing down and turning coun-terclockwise.Fill the radiator with clean deminer-alized or distilled water. Continueto add clean demineralized or dis- tilled water in small quantities until the fluid level stays up in the radia-tor neck. G050D03E

To Change the Coolant
The coolant should be changed at
those intervals specified in the ve- hicle maintenance schedule in Sec- tion 5.
! CAUTION:
Engine coolant can damage the
finish of your car. If you spill en- gine 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 radia- tor cap when cool.
2. Be sure your drain receptacle is in
place. Open the drain cock on theradiator. Allow all the engine cool- ant to drain from the cooling sys- tem, then securely close the draincock.
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 appropriatequantity of coolant to the radiator.
!WARNING:
Remove the radiator cap when the
radiator is cool. 5. Start the engine, top off the radiator
with water and then add engine coolant to the reservoir until thelevel is between "L" and "F".
6. Replace the radiator and reservoir
caps and check to be sure the draincocks are fully closed and not leak- ing.

1. Using a wrench of the correct size,
loosen the oil filler plug by turning it counterclockwise and remove it with your fingers.
2. Use your finger or suitable tool to feel inside the hole. The oil levelshould be at its bottom edge. If it is not, check for leaks before addingoil. To refill the transaxle or bring the oil level up,add oil slowly until it reaches the proper level. Do notoverfill.
3. Replace the plug and washer, screw it in with your fingers and then tighten securely with the wrench.
G110A02E-AAT
AUTOMATIC TRANSAXLE
Transaxle fluid in the automatictransaxle should be checked at those intervals specified in the vehicle main- tenance schedule in Section 5.
G100B02A-AAT
To Check the Maunal Transaxle Fluid Level
G100B01L
Park the car on level ground with the
engine off. G110B04A-AAT
Recommended Fluid
Your Hyundai automatic transaxle is
specially designed to operate with HYUNDAI GENUINE ATF SP III, DIA- MOND ATF SP-III, SK ATF SP III orother brands approved by Hundai Motor Co,. Damage caused by a nonspecified fluid is not covered byyour new vehicle limited warranty. NOTE: Automatic transaxle fluid is a red in
color. As driving distance increases, the fluid color turns darkish red gradually. It is a normal condition and you should not judge the needto replace based upon the changing color.
You must replace the automatic
transaxle fluid in accordance withintervals specified in the vehicle maintenance schedule in section5.
!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 cautionto avoid burning yourself on hot engine or exhaust parts.

CHECKING THE BRAKES
G120A01A-AAT
! CAUTION:
Because brakes are essential to
the safe operation of the car, it is suggested that they be checked and inspected by your Hyundai dealer. The brakes should bechecked and inspected for wear at those intervals specified in the vehicle maintenance schedule inSection 5.
WARNING (Diesel only):
Never work on injection system
with engine running or within 30 seconds after shutting off engine. High pressure pump, rail, injec-tors and high pressure pipes are subject to high pressure even af- ter the engine stopped. The fuel jetproduced by fuel leaks may cause serious injury, if it touch the body. People using pacemakers shouldnot move than 30cm closer to the ECU or wiring harness within the engine room while engine is run-ning, since the high currents in the Common Rail system produce considerable magnetic fields.
WARNING:
The cooling fan is controlled byengine coolant temperature and may sometimes operate even when the engine is not running. Useextreme caution when working near the blades of the cooling fan so that you are not injured by arotating fan blade. As the engine coolant temperature decreases, the fan will automatically shut off. Thisis a normal condition.
HKSOM120
Fluid level should be within this range
3. If the transaxle fluid level is low, use a funnel to add transaxle fluid through the dipstick tube until the level reaches the "HOT" range. Do not overfill.
