F030A01A-AATSCHEDULED MAINTENANCE
The following maintenance services must be performed to assure good vehicle control and performance. Keep receipts for all vehicle services to protect
your warranty. Where both mileage and time are shown, the frequency of service is determined by whichever occurs first.

VEHICLE MAINTENANCE REQUIREMENTS 5- 7
F060D01A-AATo Fuel lines, fuel hoses and
connections
Check the fuel lines, fuel hoses and connec-
tions for leakage and damage. Have a trained
techincian, replace any damaged or leaking
parts immediately.
F060C01A-AAT
o Fuel filter
A clogged filter can limit the speed at which the
vehicle may be driven, damage the emission
system and cause hard starting. If an excessive
amount of foreign matter accumulates in the fuel
tank, the filter may require replacement more
frequently.
After installing a new filter, run the engine for
several minutes, and check for leaks at the
connections.
Fuel filters should be installed by trained techni-
cians.
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 are
required.
F060A01A-AATEXPLANATION OF SCHEDULED MAIN-
TENANCE ITEMS
F060H01A-AATo Air cleaner filter
A Genuine Hyundai air cleaner filter is recom-
mended when the filter is replaced.
F060G01A-AATo Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should be
inspected at those intervals specified in the
maintenance schedule. Make sure that a new
vapor hose or fuel filler cap is correctly re-
placed.
F060F01A-AAT
o Vacuum, crankcase ventilation
hoses
Inspect the surface of hoses for evidence of
heat and/or mechanical damage. Hard and brittle
rubber, cracking, tears, cuts, abrasions, and
excessive swelling indicate deterioration. Par-
ticular attention should be paid to examine those
hose surfaces nearest to high heat sources,
such as the exhaust manifold.
Inspect the hose routing to assure that the
hoses do not come in contact with any heat
source, sharp edges or moving component which
might cause heat damage or mechanical wear.
Inspect all hose connections, such as clamps
and couplings, to make sure they are secure,
and that no leaks are present. Hoses
should be replaced immediately if there is any
evidence of deterioration or damage.
F060B01A-AAT
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 periodically for proper tension and ad-
justed as necessary.
F060J01A-AAT
o Spark plugs
Make sure to install new spark plugs of the
correct heat range.

7- 2 EMISSION CONTROL SYSTEMS
H010C01S-AAT2. Evaporative Emission Control (In-
cluding ORVR: Onboard Refueling Va-
por Recovery) System
The Evaporative Emission Control System is
designed to prevent fuel vapors from escaping
into the atmosphere.
(The ORVR system is designed to allow the
vapors from the fuel tank to be loaded into a
canister while refueling at the gas station, pre-
venting the escape of fuel vapors into the atmo-
sphere.)
Canister
Fuel vapors generated inside the fuel tank are
absorbed and stored in the onboard canister.
When the engine is running, the fuel vapors
absorbed in the canister are drawn into the
induction system through the purge control so-
lenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is controlled by
the Engine Control Module (ECM); when the
engine coolant temperature is low during idling,
the PCSV closes so that evaporated fuel is not
taken into the engine. After the engine warms-
up during ordinary driving, the PCSV opens to
introduce evaporated fuel to the engine.
H010B01A-AAT
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 crank-
case. This system supplies filtered fresh air to
the crankcase through the air intake hose. In-
side the crankcase, the fresh air mixes with
blow-by gases, then passes through the PCV
valve into the induction system.
H010A01A-AATEMISSION CONTROL SYSTEM
Your Hyundai is equipped with an emission
control system to meet all requirements of the
U.S. Environmental Protection Agency or Cali-
fornia Air Resources Board.
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 ensure 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 this
manual.
H010D01A-AAT3. EXHAUST EMISSION
CONTROL SYSTEM
The Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle
performace.
H020A01A-AATCATALYTIC CONVERTER
All Hyundai vehicles are equipped with a mono-
lith type three-way catalytic converter to reduce
the carbon monoxide, hydrocarbons and nitro-
gen oxides contained in the exhaust gas. Ex-
haust gases passing through the catalytic con-
verter cause it to operate at a very high tem-
perature. The introduction of large amounts of
