FUEL RECOMMENDATIONS
Use Unleaded Gasoline
vice stations cannot be inserted into the fuel
tank opening of your Hyundai.
WARNING: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 illumi-
nate.
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
expense.
To avoid accidental use of leaded fuel, the
larger nozzle used with leaded gasoline at ser-UNLEADED

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%
unleaded gasoline is recommended. Fuels with
unspecified quantities of alcohol, or alcohols
other than ethanol, should not be used.
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:Your Hyundai's New Vehicle Limited War-
ranty 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
B010F01A-AAT
Operation in Foreign Countries
If you are going to drive your Hyundai in another
country, be sure to:
o Observe all regulations regarding registra-
tion and insurance.
o Determine that acceptable fuel is available.
B010E01A-AAT
Gasolines for Cleaner Air
To help contribute to cleaner air, Hyundai rec-
ommends that you use gasolines treated with
detergent additives, which help prevent deposit
formation in the engine. These gasolines will
help the engine run cleaner and the Emission
Control System performance.

gen Content 2.7% weight.)
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.

EMISSION CONTROL SYSTEMS
7-1
7. EMISSION CON-
TROL SYSTEMSH010B01A-AAT1. 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 fresh filtered air to
the crankcase through the air intake hose.
Inside the crankcase, the fresh air mixes with
blow-by gases, which then pass through the
PCV valve and into the induction system.
H010C01S-AAT2. Evaporative Emission Control (In-
cluding ORVR: Onboard Refueling
Vapor 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,
preventing the escape of fuel vapors into
the atmosphere.)
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.
H010D01A-AAT
3. Exhaust Emission Control System
The Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle per-
formance.
H010A01GK-AAT
EMISSION 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.
Caution for Inspection and Maintenance Test
(Vehicle with Traction Control System)
o To prevent the vehicle from misfiring
during dynamometer testing, disconnect
the ABS connector located inside of the
wheel guard (driver side).
o For more information, see shop manual
(BR Group, Wheel Speed Sensor).
