F060A01A-AAT
EXPLANATION OF SCHEDULED MAIN- TENANCE ITEMS
F060M01A-AAT
o Engine oil and filter The 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 arerequired.
F060B01A-AAT
o Drive belts
Inspect all drive belts for evidence of cuts,
cracks, excessive wear or oil and replace ifnecessary. Drive belts should be checked pe-
riodically for proper tension and adjusted asnecessary.
F060C01A-GAT
o Fuel filter
A clogged filter can limit the speed at which the
vehicle may be driven, damage the emissionsystem and cause hard starting. If an exces-sive amount of foreign matter accumulates inthe fuel tank, the filter may require replacementmore frequently.
After installing a new filter, run the engine for
several minutes, and check for leaks at theconnections. F060D01A-GAT
o Fuel lines, fuel hoses and connec-
tions
Check the fuel lines, fuel hoses and connec-
tions for leakage and damage. Replace anydamaged or leaking parts immediately. Inspect the hose routing to assure that the
hoses do not come in contact with any heatsource, sharp edges or moving component
which might cause heat damage or mechanicalwear. Inspect all hose connections, such as
clamps and couplings, to make sure they aresecure, and that no leaks are present. Hoses
should be replaced immediately if there is any
evidence of deterioration or damage.
F060H01A-AAT
o Air cleaner filter
A Genuine Hyundai air cleaner filter is recom-
mended when filter is replaced.
F060J01A-AAT
o Spark plugs
Make sure to install new spark plugs of the
correct heat range.
F060E01A-AAT
o Timing belt Inspect all parts related to the timing belt for
damage and deformation. Replace any dam-aged parts immediately.
F060G01A-AAT
o Vapor hose and fuel filler cap The vapor hose and fuel filler cap should be
inspected at those intervals specified in themaintenance schedule. Make sure that a newvapor hose or fuel filler cap is correctly re-placed.
F060F01A-AAT
o Vacuum, crankcase ventilation hos-
es
Inspect the surface of hoses for evidence of
heat and/or mechanical damage. Hard and brit-tle rubber, cracking, tears, cuts, abrasions, and
excessive swelling indicate deterioration. Par-ticular attention should be paid to examinethose hose surfaces nearest to high heat sourc-es, such as the exhaust manifold. F060N01X-GAT
o Valve clearances Incorrect valve clearance will not only result in
unsteady engine operation, but will also causeexcessive noise and reduced engine perfor-
mance. Inspect valve clearance and adjust asrequired while the engine is hot.

REPLACING THE SPARK PLUGS
The spark plugs should be changed at the
intervals specified in the vehicle maintenance schedule in Section 5 or whenever engine per-formance indicates they should be changed.Symptoms that suggest poor spark plug perfor-mance include engine misfiring under load, lossof fuel economy, poor acceleration, etc. Whenspark plugs are replaced, always use sparkplugs recommended by Hyundai. The use ofother spark plugs can result in loss of perfor-mance, radio interference or engine damage.
NOTE: When replacing the spark plug, always use
the genuine parts recommended.

5. Start the engine, top off the radiator with water and then add engine coolant to the reservoir until the level is between "LOW"and "FULL".
6. Replace the radiator and reservoir caps and check to be sure the drain cocks are fullyclosed and not leaking.
WARNING: The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper- ate even when the engine is not running.Use extreme caution when working near theblades of the cooling fan so that you are notinjured by a rotating fan blade. As the en-gine coolant temperature decreases, the fanwill automatically shut off. This is a normalcondition.

EMISSION CONTROL SYSTEMS 7-1
7. EMISSION CON-
TROL SYSTEMS
H010A01A-GAT
EMISSION CONTROL SYSTEM (If Installed)
Your Hyundai is equipped with an emission
control system to meet all requirements of the Emission prohibition rules of your province. There are three emission control systems which
are as follows.
1) Crankcase emission control system
2) Evaporative emission control system
3) Exhaust emission control system In order to assure the proper function of the
emission control systems, it is recommended that you have your car inspected and main-tained by an authorized Hyundai dealer in ac-cordance with the maintenance schedule in thismanual. the crankcase through the air intake hose.Inside the crankcase, the fresh air mixes withblow-by gases, which then pass through thePCV valve and into the induction system.
H010C02A-GAT
2. Evaporative Emission Control
System (If installed)
The Evaporative Emission Control System is
designed to prevent fuel vapors from escapinginto the atmosphere. Canister
While the engine is inoperative, fuel vapors
generated inside the fuel tank are absorbed and stored in the onboard canister. When the en-gine is running, the fuel vapors absorbed in thecanister are drawn into the induction systemthrough
the purge control solenoid valve.
Purge Control Solenoid Valve The purge control solenoid valve is controlled
by the ECM; when the engine coolant temper-ature is low, and during idling, it closes, so thatevaporated fuel is not taken into the engine.After engine warm-up, during ordinary driving, itopens so as to introduce evaporated fuel to theengine.
H010B01A-AAT
1. Crankcase Emission Control Sys-
tem
The Positive Crankcase Ventilation System is
employed to prevent air pollution caused byblow-by gases being emitted from the crank-case. This system supplies fresh filtered air to H010D01A-AAT
3. Exhaust Emission Control System
The exhaust emission control system is a high-
ly effective system which controls exhaust emis-sion while maintaining good vehicle perfor-mance.
H020A01A-GAT
CATALYTIC CONVERTER (If Installed)
The catalytic converter is part of the exhaust
emission control system. It's purpose is to re-move certain engine emission products from
the engine's exhaust. It looks something like amuffler and is located underneath the car in theexhaust system. Catalytic Converter
