2MAINTENANCE INTERVALS
F010C01A-GAT
Specified Scheduled Procedures
These are the procedures such as
inspections, adjustments and replace- ments that are listed in the mainte-nance charts starting on page 5-4. These procedures must be performed at the intervals shown in the mainte-nance schedule to assure that your warranty remains in effect. Although it is strongly recommended that they beperformed by the factory-trained or distributor-trained technicians at your Hyundai dealer, these procedures maybe performed at any qualified service facility. F010D01A-AAT
General Checks
These are the regular checks you should perform when you drive your Hyundai or you fill the fuel tank. A list of these items will be found on page6-7.
F010A01A-GAT Service Requirements To assure that you receive the great- est number of kilometers of satisfying operation from your Hyundai, certain maintenance procedures must be per-formed. Although careful design and engineering have reduced these to a minimum, those that are required areof the utmost importance.It is your responsibility to have thesemaintenance procedures performed to comply with the terms of the warran- ties covering your new Hyundai. TheService Passport supplied with your new vehicle provides further informa- tion about these warranties.
F010B01A-AAT
Maintenance Requirements
The maintenance required for your
Hyundai can be divided into three main areas: o Specified scheduled procedures o General checks o Do-it-yourself maintenance It is suggested that genuine Hyundai
service parts be used for any requiredrepairs or replacements. Other parts of equivalent quality such as engine oil, engine coolant, manual or autotransaxle oil, brake fluid and so on which are not supplied by Hyundai Motor Company or its distributor maybe used without affecting your war- ranty coverage but you should always be sure these are equivalent to thequality of the original Hyundai parts. Your Service Passport provides fur- ther information about your warrantycoverage.

8EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
!
F060M01A-AAT o Engine Oil and Filter The 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. F060B01A-AAT
o Drive Belts Inspect all drive belts for evidence of cuts, cracks, excessive wear or oil and replace if necessary. Drive belts should be checked periodically forproper tension and adjusted as neces- sary. F060C01A-AAT
o Fuel Filter
A clogged filter can limit the speed at
which the vehicle may be driven, dam-age the emission system and cause hard starting. If an excessive amountof foreign matter accumulates in the fuel tank, the filter may require re- placement more frequently. After installing a new filter, run the
engine for several minutes, and checkfor leaks at the connections. Fuel fil- ters should be installed by trained technicians. WARNING (Diesel only):
Never work on injection system with engine running or within 30 sec- onds after shutting off engine. Highpressure pump, rail, injectors and high pressure pipes are subject to high pressure even after the enginestopped. The fuel jet produced by fuel leaks may cause serious injury, if it touch the body. People usingpacemakers should not move than 30cm closer to the ECU or wiring harness within the engine roomwhile engine is running, since the high currents in the Common Rail system produce considerable mag-netic fields.
F060D01TB-AAT
o Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.Replace any damaged or leaking partsimmediately.

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.

F070F01A-AAT
o Brake Hoses and Lines
Visually check for proper installation, chafing, cracks, deterioration and anyleakage. Replace any deteriorated or damaged parts immediately. F070G02A-AAT
o Brake Fluid
Check brake fluid level in the brake fluid reservoir. The level should be between "MIN" and "MAX" marks on the side of the reservoir. Use onlyhydraulic brake fluid conforming to DOT 3 or DOT 4.
F070H01A-AAT
o Rear Brake Drums/Linings,
Parking Brake
Check the rear brake drums and lin-
ings for scoring, burning, leaking fluid, broken parts, and excessive wear. Inspect the parking brake system in- cluding the parking brake lever andcables. For detailed service proce- dures, refer to the Shop Manual.
F070D01A-AAT
o Manual Transaxle Oil Inspect the manual transaxle oil ac- cording to the maintenance schedule. NOTE: If the oil level is low, check for possible leaks before adding oil.Do not overfill.
F070C02A-AAT
o Coolant The coolant should be changed at the intervals specified in the mainte- nance schedule.
F070E06A-AAT
o Automatic Transaxle Fluid
The fluid level should be in the "HOT" range of the dipstick, after the engine and transaxle are at normal operating temperature. Check the automatictransaxle fluid level with the engine running and the transaxle in neutral, with the parking brake properly ap-plied. Use HYUNDAI GENUINE ATF SP III, DIAMOND ATF SP III, SK ATF SP III or other brands approved byHyundai Motor Co., when adding or changing fluid. Using the wrong ATF may result in damage to the ATM.

8CHECKING THE ENGINE OIL
G030B02FC-GAT
Recommended Oil Diesel Engine
G030B01A
Engine oil is essential to the perfor-
mance and service of the engine. It is suggested that you check the oil level every 500km or before starting a longtrip and more often if you are driving in severe conditions.
The engine oil quality should meet
the following classification:
API class: CF-4 or ABOVE ACEA class: B4 or ABOVE
G030A02O-GAT
Recommended Oil Gasoline Engine Engine oil is essential to the perfor- mance and service of the engine. It is suggested that you check the oil level at least once a week in normal use andmore often if you are on a trip or driving in severe conditions. The engine oil quality should meet the following classification. API SJ, SL or ABOVE, ILSAC GF-3 or ABOVE G030B01JMNOTE:
o For good fuel economy, SAE 5W- 20 (5W-30), ILSAC GF-3 engine oilis preferred regardless of regional option and engine variation.
o If SAE 5W-20, ILSAC GF-3 engine oil is not available, secondaryrecommended engine oil for cor- responding temperature rangecan be used.
