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.
F060B02A-AAT
o Drive Belts Inspect all drive belts for evidence of cuts,
cracks, excessive wear or oil saturation andreplace if necessary. Drive belts should bechecked periodically for proper tension andadjusted as necessary.
F060C01A-AAT
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. Fuel filters should be installed bytrained technicians. F060D01A-AAT
o Fuel Lines, Fuel Hoses and Connec-
tions
Check the fuel lines, fuel hoses and connec-
tions for leakage and damage. Have a trainedtechnician replace any damaged or leaking partsimmediately.

Your engine was originally equipped with plati- num-tipped spark plugs. (For 2.7L only). Platinum-tipped spark plugs will last longer than conventional type spark plugs and can be iden-tified by blue lines on the ceramic shell. NOTE: Do not clean or regap platinum-tipped spark plugs. G060B01GK-GAT
Replacing the Spark Plugs
The spark plugs should be changed at the
intervals specified in the vehicle maintenanceschedule 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 plugs, genuine
Hyundai replacement parts are recom- mended. Recommended Spark Plugs:

Changing the Spark Plugs
You will find it easier to change spark plugs if
the engine is cold. Always change one spark plug at a time. This helps avoid getting the wiresmixed up.
1. Remove the engine rocker cover.
NOTE: It is recommended that the spark plugs for
2.7L Engines should be changed by an au- thorized Hyundai dealer.
2. Using a clean cloth, remove any dirt that has accumulated around the base of the spark plug so it cannot fall into the cylinder whenthe spark plug is removed.
3. To remove the spark plug cable, pull straight up on the insulated connector, not the cable.Pulling on the cable may damage the carboncore conductor.

7. EMISSION
CONTROL SYSTEMS
H010B01F-GAT
1. Crankcase Emission Control Sys-
tem
The positive crankcase ventilation system is
employed to prevent air pollution caused by H010A01A-GAT
EMISSION CONTROL SYSTEMS (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. H010C01F-GAT
2. Evaporative Emission Control Sys-
tem (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 canister. When the engine is
running, the fuel vapors absorbed in the canis-ter are drawn into the induction system throughthe purge control solenoid valve. Purge Control Solenoid Valve
The purge control solenoid valve is controlled
by the ECM; when the engine coolant tempera- ture is low, and during idling, it closes, so that
evaporated fuel is not taken into the engine.After engine warm-up, during ordinary driving, itopens so as to introduce evaporated fuel to theengine. H010D01A-AAT
3. Exhaust Emission Control System
The exhaust emission control system is a high-
ly effective system which controls exhaust emis-sions while maintaining good vehicleperformace.
H020A01A-GAT
CATALYTIC CONVERTER (If Installed)
Catalytic Converter
SSA7020A
The catalytic converter is part of the exhaust
emission control system. Its purpose is to re- move certain engine emission products fromthe engine's exhaust. It looks something like amuffler and is located underneath the car in theexhaust system.
blow-by gases being emitted from the crank-
case. This system supplies fresh air to the
crankcase through the air cleaner. Inside thecrankcase, the fresh air mixes with blow-bygases, then passes through the PCV valve intothe induction system.

About the Catalytic Converter
Exhaust gases passing through the catalytic
converter cause it to operate at very high tem- peratures. As a result, the introduction of largeamounts of unburned gasoline may cause it tooverheat and create a fire hazard. This can beavoided by observing the following:
o Use unleaded fuel only.
o Maintain your engine in good condition. Ex- tremely high converter temperatures can result from improper operation of the electri-cal, ignition or fuel injection systems.
o If your engine stalls, pings, knocks, or is hard to start, take your car to your Hyundaidealer as soon as possible and have thedifficulty corrected.
o Avoid driving with a very low fuel level. If your run out of gasoline, it could cause theengine to misfire and result in excessiveloading of the catalytic converter.
o Avoid idling the engine for periods longer than 10 minutes.
o Your Hyundai should not be either pushed or pulled to get it started. This can cause thecatalytic converter to overload.
o Take care not to stop your Hyundai over any combustible material such as grass, paper,leaves or rags. As these materials couldcome in contact with the catalytic converterand could cause a fire. o Do not touch the catalytic converter or any
other part of the exhaust system while theengine is running as it is very hot and couldresult in burns.
o Remember that your Hyundai dealer is your best source of assistance.
