EMISSION CONTROL SYSTEMS2
EMISSION CONTROL SYSTEMH010A02L-AATYour 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 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 this
manual.
Caution for the Inspection and Maintenance
Test (3.5 V6 Vehicle with Traction Control
System)
After dynamometer testing is completed,
erase the ABS/TCS DTC(Diagnotic Trouble
Code) with a GST (Generic Scan Tool) or Hi-
Scan Pro.
H010B01A-AAT1. Crankcase Emission Control
SystemThe 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 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 (Includ-
ing ORVR: Onboard Refueling Vapor
Recovery) SystemThe 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.)CanisterFuel 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.

CATALYTIC CONVERTER
!
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, igni-
tion or multiport electronic fuel injec-
tion.
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 cre-
ate a fire hazard.
H020A01A-AATAll Hyundai vehicles are equipped with a mono-
lith type three-way catalytic converter to re-
duce the carbon monoxide, hydrocarbons and
nitrogen oxides contained in the exhaust gas.
Exhaust gases passing through the catalytic
converter cause it to operate at a very high
temperature. The introduction of large amounts
of unburned gasoline into the exhaust may
cause the catalytic converter to overheat and
create a fire hazard. This risk may be reduced
by observing the following:Catalytic Converter
H020A01L
H010E01Y-AATEGR System (If Installed)This system helps reduce nitrogen oxides by
recirculating a part of the exhaust gas into the
engine, thereby reducing cylinder combustion
temperature, which results in lower output of
oxides of nitrogen.H010D01A-AAT3. Exhaust Emission Control SystemThe Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle per-
formance.

WARNING:
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.
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.

RECOMMENDED INFLATION
PRESSURESI030A03L-AATTire label located on the driver's door
edge gives the cold tire pressures rec-
ommended for your vehicle with the
original tire size, the number of people
that can be in your vehicle and vehicle
capacity weight.
I030A01L
These pressures were chosen to pro-
vide the most satisfactory combination
of ride comfort, tire wear and stability
under normal conditions. Tire pressures
should be checked at least monthly.
Proper tire inflation pressures should
be maintained for these reasons:
!
CAUTION:
Always observe the following:
o Check pressures when the tires
are cold. That is, after the car has
been parked for at least three hours
and hasn't been driven more than
one mile or 1.6 km since starting
up.WARNING:
o Lower-than-recommended tire
pressures cause uneven tread
wear, poor handling, pour fuel
economy or tire failure.
o Higher-than-recommended tire
pressures can cause poor han-
dling, uneven tread wear or tire
failure.
