6ZF060M1-A
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. 6ZF060B1-A
o Drive belts
Inspect all drive belts for evidence of cuts, cracks, excessive wear or oil saturation and replace if necessary. Drive belts should be checked peri-odically for proper tension and ad- justed as necessary. 6ZF060C1-A
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.
F060D01TB-EAT
o Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and damage.Replace any damaged or leaking partsimmediately. WARNING (Diesel only):
Never work on injection system with engine running or within 30 seconds after shutting off engine.High pressure pump, rail, injectors and high pressure pipes are sub- jected to high pressure even afterthe engine has been switched off. The fuel jet produced by fuel leaks may cause serious injury, if it con-tacts with the body. People using pacemakers should not move closer than 12 in.(30 cm) to the ECUor wiring harness within the engine room with the engine running, since the high currents in the CommonRail system produce considerable magnetic fields.

o Coolant
The engine coolant should be changed
at the intervals specified in the main- tenance schedule. F060H01A-AAT
o Air cleaner filter
A Genuine Hyundai air cleaner filter is
recommended when the filter is re- placed.
6ZF060J1-A
o Spark plugs
(For Petrol Engine)
Make sure to install new spark plugs
of the correct heat range.
6ZF070B1-A
o Cooling system
Check the cooling system part, such as radiator, coolant reservoir, hoses and connections for leakage and dam- age. Replace any damaged parts.
6ZF060G1-A o Vapour hose and fuel filler cap The vapour hose and fuel filler cap should be inspected at those intervals specified in the maintenance sched- ule. Make sure that a new vapourhose or fuel filler cap is correctly re- placed. 6ZF060F1-A
o Vacuum, crankcase
ventilation hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical dam-age. Hard and brittle rubber, cracking, tears, cuts, abrasions, and excessiveswelling indicate deterioration. Par- ticular attention should be paid to ex- amining those hose surfaces nearestto high heat sources, such as the exhaust manifold.
Inspect the hose routing to assure
that the hoses do not come in contactwith any heat source, sharp edges or moving component which might causeheat damage or mechanical wear. Inspect all hose connections, such as clamps and couplings, to make surethey are secure, and that no leaks are present. Hoses should be replaced immediately if there is any evidence ofdeterioration or damage.
6ZF060E1-A o Timing belt Replace timimg belt and inspect all associated parts related for damage and deformation. Replace any dam- aged parts immediately.

ENGINE OIL AND FILTER REPLACEMENT
o The engine oil consumption is strongly effected by the viscosity and quality of oil, engine rpm and driving condi- tion etc. More engine oil may be consumedunder severe driving conditions such as high speeds, frequent accelera- tion and deceleration, compared tonormal driving. G040A04A-EAT
The engine oil and filter must be changedat the time or mileage interval specifiedin the maintenance schedule. If the vehicle is operated under severe or adverse conditions, the oil and filtermust be replaced more frequently. To replace the oil and filter, proceed as follows:
1. Ensure that the engine is at normaloperating temperature and park the vehicle on level ground with the park- ing brake securely applied and the engine turned off.
2. Open the bonnet and remove the oil filler cap.

!Open the bonnet and remove the transaxle dipstick, remembering that care must be exercised to prevent in-jury occurring through contact with hot or rotating parts of the engine. WARNING:
The cooling fan is controlled by en- gine coolant temperature and maysometimes operate even when the engine is not running. Use extreme caution when working near theblades of the cooling fan so that you are not injured by a rotating fan blade. As the engine coolant tem-perature decreases, the fan will auto- matically shut off. This is a normal condition.
Wipe the dipstick, replace it fully andpromptly remove it again. The fluidlevel should be between the upper and lower marks. Fluid need only be added if the level is at or below the lower markand must never be increased above the higher mark. If additional fluid is re- quired, this should be poured into thetransmission through the dipstick tube with the aid of a suitable funnel.
G110D03A
G110D04A
Fluid level should be within "HOT" range
!WARNING (Diesel only):
Never work on injection system with engine running or within 30 seconds after shutting off engine. High pres-sure 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 12 in.(30 cm) closer to the ECU or wiring harness within the engine room while engine is running, since the high currents in the CommonRail system produce considerable magnetic fields.

7EMISSION CONTROL SYSTEMS
2EMISSION CONTROL SYSTEMS
SH010A1-E (Not all models) Depending upon the market for which the vehicle is destined, the emission control system will comprise one or more of the following emission con-trol devices.
1) Crankcase emission control sys-
tem
2) Evaporative emission control sys-
tem
3) Exhaust emission control system In order that the proper functioning of the emission control systems may be ensured, it is recommended that thevehicle is inspected and maintained by an authorized Hyundai dealer in accordance with the maintenanceschedule in this manual. SH010B1-E
1. Crankcase Emission
Control System
The positive crankcase ventilation
system is employed to prevent air pollution caused by blow-by gases being emitted from the crankcase byintroducing fresh air to the crankcase through the air cleaner where this mixes with blow-by gases and thenpasses through the PCV valve into the intake manifold from where it sub- sequently enters the combustionchamber and is burned.
SH010C1-E
2. Evaporative Emission
Control System
The Evaporative Emission Control
System is designed to prevent fuel vapours from escaping into the atmo- sphere through the fuel tank ventila-tion system. Canister
Fuel vapours generated inside the
fuel tank are absorbed and stored ina charcoal canister. When the engineis started, the vapours stored in the canister are drawn into the induction system through the purge control so-lenoid valve and are subsequently burned. Purge Control Solenoid Valve
The purge control solenoid valve is
controlled by the ECU; when the en- gine coolant temperature is low or the engine is idling, the purge control valve is closed and fuel vapours re- main stored in the canister. Undernormal running conditions when the engine is warm, the valve opens and the vapours are drawn into the inlettract and subsequently burned in the combustion chamber.
