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.

NUMBER (VIN)
I010B01A-AAT I010A01O-AAT
The vehicle identification number (VIN) is the
number used in registering your car and in all
legal matters pertaining to its ownership, etc. It
can be found in three different places on your
car:
1. On the bulkhead between the engine and
passenger compartments.
2. On the left top side of the instrument panel
where it can be seen by looking down through
the windshield.
3. On the lower side of the center pillar outer
panel.
The engine number is stamped on the engine
block as shown in the drawing.
TIRESI020A02A-AATTIRE INFORMATIONThe tires supplied on your new Hyundai
are chosen to provide the best perfor-
mance for normal driving.
If you ever have questions about your
tire warranty and where to obtain ser-
vice, see the tire manufacturer's book-
let included with your vehicle's Owner's
Manual Literature Kit.

I030A03NF-AATRECOMMENDED COLD TIRE INFLA-
TION PRESSURES
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:
I030A01NF-AI030A03NF-A
I030A04NF-A
!
WARNING:
o Inspect your tires frequently for
proper inflation as well as wear
and damage. Always use a tire
pressure gauge.
o Tires with too much or too little
pressure wear unevenly causing
poor handling, loss of vehicle
control, and sudden tire failure
leading to accidents, injuries, and
even death. The recommended
cold tire pressure for your vehicle
can be found in this manual and
on the tire label located on the
driver's side of the center pillar.
o Worn tires can cause accidents.
Replace tires that are worn, show
uneven wear, or are damaged. See
page 8-11.
o Remember to check the pressure
of your spare tire. Hyundai recom-
mends that you check the spare
every time you check the pressure
of the other tires on your vehicle.
