EMISSION CONTROL SYSTEM
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
crankcase. 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 induc-
tion system.
H010A01NF-AATYour Hyundai is equipped with an emis-
sion 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 recom-
mended that you have your car inspected
and maintained by an authorized Hyundai
dealer in accordance with the maintenance
schedule in this manual.
Caution for the Inspection and Mainte-
nance 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 com-
pleted, turn the ESC system back on
by pressing the ESC switch again.
H010C01S-AAT2. Evaporative Emission Control (In-
cluding ORVR: Onboard Refuel-
ing Vapor Recovery) SystemThe Evaporative Emission Control Sys-
tem 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 va-
pors into the atmosphere.)CanisterFuel vapors generated inside the fuel tank
are absorbed and stored in the canister.
When the engine is running, the fuel va-
pors absorbed in the canister are drawn
into the induction system through the purge
control solenoid valve.

H010D01A-AAT3. Exhaust Emission Control Sys-
temThe Exhaust Emission Control System is a
highly effective system which controls ex-
haust emissions while maintaining good
vehicle performace.Purge Control Solenoid Valve (PCSV)The purge control solenoid valve is con-
trolled by the Engine Control Module
(ECM); when the engine coolant tempera-
ture 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 intro-
duce evaporated fuel to the engine.
CATALYTIC CONVERTER
!
WARNING:
o Use unleaded fuel only.
o Maintain the engine in good operating
condition. Extremely high catalytic
converter temperatures can result
from improper operation of the elec-
trical, ignition or multiport electronic
fuel injection.
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 create a fire hazard.
H020A01A-AATAll Hyundai vehicles are equipped with a
monolith type three-way catalytic converter
to reduce the carbon monoxide, hydrocar-
bons 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:

!
o Do not touch the catalytic converter
or any other part of the exhaust sys-
tem 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
combustible material such as grass,
paper, leaves or rags. These materi-
als might contact the hot catalytic
converter and a fire might result.WARNING:
