1FEATURES OF YOUR HYUNDAI
2FUEL RECOMMENDATIONS
B010A02A-AAT
Use Unleaded Gasoline
Unleaded gasoline with a Pump Octane Rating
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 service
stations cannot be inserted into the fuel tank
opening of your Hyundai.
B010A03E
UNLEADED
FUEL ONLY
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 illu-
minate.

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.
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
starting.
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
Tertiary Butyl Ether) over 15.0% vol. (Oxy-
gen Content 2.7% weight.).
7EMISSION CONTROL SYSTEMS
2EMISSION CONTROL SYSTEM
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.
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 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.
H010A01A-AAT
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.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
solenoid 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.
H010C01S-AAT2. Evaporative Emission Control
(Including 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, pre-
venting the escape of fuel vapors into the
atmosphere.)
