FUEL RECOMMENDATIONS
Use Unleaded Gasoline
Unleaded gasoline with a Pump Octane Rat-
ing of 87 (Research Octane Number 91) or
higher must be used in your Hyundai.
If leaded gasoline is used, it will cause the
catalytic converter to become ineffective and
the emission control system to malfunction. This
can also result in increased maintenance ex-
pense.
To avoid accidental use of leaded fuel, the larger
nozzle used with leaded gasoline at service
stations cannot be inserted into the fuel tank
opening of your Hyundai.
B010B01A-AAT
What About Gasohol?
Gasohol (a mixture of 90% unleaded gasoline
and 10% ethanol or grain alcohol) may be used
in your Hyundai. However, if your engine devel-
ops driveability problems, the use of 100% un-
leaded gasoline is recommended. Fuels with
unspecified quantities of alcohol, or alcohols
other than ethanol, should not be used.
B010C01A-AAT
Use of MTBE
Hyundai recommends that fuels containing
MTBE (Methyl Tertiary Butyl Ether) over 15.0%
vol. (Oxygen Content 2.7% weight) should not
be used in your Hyundai.
Fuel containing MTBE over 15.0% vol. (Oxygen
Content 2.7% weight) may reduce vehicle per-
formance and produce vapor lock or hard start-
ing.
B010D01A-AAT
Do Not Use Methanol
Fuels containing methanol (wood alcohol) should
not be used in your Hyundai. This type of fuel
can reduce vehicle performance and damage
components of the fuel system.CAUTION:o Do not "TOP-OFF" after the first nozzle
shut off when refueling.
o The fuel cap must be tightened at least 3
clicks, otherwise " " light may ill-
uminate.
CAUTION:Your Hyundai's New Vehicle Limited Warran-
ty may not cover damage to the fuel system
and any performance problems that are caused
by the use of fuels containing methanol or
fuels containing MTBE (Methyl Tertiary Butyl
Ether) over 15.0% vol. (Oxygen Content 2.7%
weight.)

3- 2 WHAT TO DO IN AN EMERGENCY
!
D010B02A-AAT
If Engine Doesn't Turn Over or Turns
Over Slowly
D010A01A-AATIF THE ENGINE WILL NOT START
D010C01A-AATIf Engine Turns Over Normally but Does
Not Start
1. Check fuel level.
2. Check all connectors at ignition coil and
spark plugs. Reconnect any that may be
disconnected or loose.
3. Check the fuel line in the engine room.
4. If the engine still refuses to start, call a
Hyundai dealer or seek other qualified assis-
tance.
D010D01A-AAT
If the Engine Stalls While Driving
1. Reduce your speed gradually, keeping a
straight line. Move cautiously off the road to
a safe place.
2. Turn on your emergency flashers.
3. Try to start the engine again. If your vehicle
will not start, contact a Hyundai dealer or
seek other qualified assistance.
WARNING:If the engine will not start, do not push or
pull the car to start it. This could result in a
collision or cause other damage. In addition,
push or pull starting may cause the catalytic
converter to be overloaded and create a fire
hazard.
D010B01AD010C01A-D
1. If your car has an automatic transaxle, be
sure the gear selector lever is in "N" or "P"
and the emergency brake is set.
2. Check the battery connections to be sure
they are clean and tight.
3. Turn on the interior light. If the light dims or
goes out when you operate the starter, the
battery is discharged.
4. Check the starter connections to be sure
they are securely tightened.
5. Do not push or pull the vehicle to start it. See
instructions for "Jump Starting".

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
HLC5022Catalytic Converter

EMISSION CONTROL SYSTEMS 7- 3
unburned gasoline into the exhaust may cause
the catalytic converter to overheat and create a
fire hazard. This risk may be reduced by ob-
serving the following:
WARNING:o Remember that your Hyundai dealer is
your best source of assistance.
o Do not stop your Hyundai over any com-
bustible material such as grass, paper,
leaves or rags. These materials might
contact the hot catalytic converter and a
fire might result.
WARNING:o Use unleaded fuel only.
o Maintain the engine in good operating
condition. Extremely high catalytic con-
verter temperatures can result from im-
proper operation of the electrical, ignition
or multiport electronic fuel injection.
o If your engine stalls, pings, knocks, or is
hard to start, have your Hyundai dealer
inspect and repair the problem as soon
as possible.
o Avoid driving with a very low fuel level.
Running out of gasoline may cause the
engine to misfire and result in damage to
the catalytic converter.
o Avoid idling the engine for periods longer
than 10 minutes.
o The vehicle should not be pushed or
pulled to get started. This may cause the
catalytic converter to overheat and create
a fire hazard.
o Do not touch the catalytic converter or
any other part of the exhaust system
while the catalytic converter is hot. Shut
off the engine, wait for at least one hour
before touching the catalytic converter or
any other part of the exhaust system.
