EMISSION CONTROL SYSTEMS2
EMISSION CONTROL
SYSTEMS
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 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 into the induction system.
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
surge tank 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.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.
H010A01NF-AATYour Hyundai is equipped with an emission
control system to meet all emission regulations.
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 (With Electronic Stability Control (ESC)
system)
o To prevent the vehicle from misfiring
during dynamometer testing, turn the
Electronic Stability Control (ESC) sys-
tem off by pressing the ESC switch.
o After dynamometer testing is completed,
turn the ESC system back on by pressing
the ESC switch again.
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, pre-
venting the escape of fuel vapors into the
atmosphere.)

CATALYTIC CONVERTERH020A01A-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
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.
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.
H020A01NF
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.

I030A01NF-AATRECOMMENDED INFLATION PRES-
SURES
Tire label located on the driver's side of
the center pillar outer panel gives the
cold tire pressures recommended for
your vehicle with the original tire size,
the number of people that can be in your
vehicle and vehicle capacity weight.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. (After the vehicle has
been parked for at least three hours
or hasn't been driven more than 1
mile (1.6 km) since starting up.)
!
WARNING:
o Lower-than-recommended tire
pressures cause uneven tread
wear, poor handling, poor fuel
economy or tire failure.
o Higher-than-recommended tire
pressures can cause poor han-
dling, uneven tread wear or tire
failure.

Check the tire's inflation pressure when
the tires are cold. - "Cold" means your
vehicle has been sitting for at least
three hours or driven no more than 1
mile (1.6 km).
Remove the valve cap from the tire
valve stem. Press the tire gauge firmly
onto the valve to get a pressure mea-
surement. If the cold tire inflation pres-
sure matches the recommended pres-
sure on the tire and loading information
label, no further adjustment is neces-
sary. If the pressure is low, add air until
you reach the recommended amount.
If you overfill the tire, release air by
pushing on the metal stem in the center
of the tire valve. Recheck the tire pres-
sure with the tire gauge. Be sure to put
the valve caps back on the valve stems.
They help prevent leaks by keeping out
dirt and moisture. o Check the pressure of your spare
tire each time you check the pres-
sure of other tires.
o Worn, old tires can cause acci-
dents. If your tread is badly worn,
or if your tires have been dam-
aged, replace them.
I035A01JM-AATCHECKING TIRE INFLATION PRES-
SURE
Check your tires once a month or more.
Also, check the tire pressure of the
spare tire.
How to Check
Use a good quality gauge to check tire
pressure. You cannot tell if your tires
are properly inflated simply by looking
at them. Radial tires may look properly
inflated even when they're underinflated.
Federal law requires tire manufacturers
to place standardized information on
the sidewall of all tires. This information
identifies and describes the fundamen-
tal characteristics of the tire and also
provides the tire identification number
(TIN) for safety standard certification.
The TIN can be used to identify the tire
in case of a recall.I030B01NF-AATTIRE SIDEWALL LABELING
