EMISSION CONTROL
SYSTEMS
H010B01A-AAT1. Crankcase Emission Control Sys-
temThe positive crankcase ventilation system
is employed to prevent air pollution caused
by blow-by gases being emitted from the
crankcase. 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.
H010A02NF-AATThe emission control system of your ve-
hicle is covered by a written limited war-
ranty. Please see the warranty information
contained in the Owner’s Handbook &
Warranty Information booklet in your ve-
hicle.
Your vehicle is equipped with an emission
control system to meet all applicable emis-
sion regulations.
There are three emission control systems,
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 vehicle
inspected and maintained by an autho-
rized 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 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.)

H010D01NF-AAT3. Exhaust Emission Control
SystemThe Exhaust Emission Control System is a
highly effective system which controls
exhaust emissions while maintaining good
vehicle performance.G270301AUNVehicle modificationsThis vehicle should not be modified. Modi-
fication of your vehicle could affect its per-
formance, safety or durability and may
even violate governmental safety and
emissions regulations.
In addition, damage or performance prob-
lems resulting from any modification may
not be covered under warranty.G270302AUNEngine exhaust gas precautions
(carbon monoxide)Carbon monoxide can be present with
other exhaust fumes. Therefore, if you smell
exhaust fumes of any kind inside your
vehicle, have it inspected and repaired
immediately. If you ever suspect exhaust
fumes are coming into your vehicle, drive
it only with all the windows fully open. Have
your vehicle checked and repaired imme-
diately.

PROPOSITION 65 WARNING:
Engine exhaust and a wide variety of
automobile components and parts, in-
cluding components found in the interior
furnishings in a vehicle, contain or emit
chemicals known to the State of Califor-
nia to cause cancer and birth defects
and reproductive harm. In addition, cer-
tain fluids contained in vehicles and
certain products of component wear
contain or emit chemicals known to the
State of California to cause cancer and
birth defects or other reproductive harm.
CATALYTIC CONVERTERH020A01NF-AAT(If Installed)Hyundai vehicle is equipped with a mono-
lith 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:Catalytic Converter
H020A01NF
!
WARNING - Exhaust
Engine exhaust gases contain carbon
monoxide (CO). Though colorless and
odorless, it is dangerous and could be
lethal if inhaled. Follow the instructions
on this page to avoid CO poisoning.

WARNING:
!
WARNING:
o Your vehicle is designed to operate
with a catalytic converter and remov-
ing it will cause the engine to operate
poorly and fuel economy to drop along
with an increase in the vehicle emis-
sions.
o Remember that your Hyundai dealer
is your best source of assistance.
o Do not park, idle or drive your vehicle
over or near flammable objects such
as grass, paper, leaves or rags. These
materials might contact the hot cata-
lytic converter and a fire might result. 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
electrical, 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.
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 cata-
lytic converter or any other part of the
exhaust system.
