H010D01A-AAT
3. Exhaust Emission Control System
The Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle
performace.
H010B01A-AAT
1. Crankcase Emission Control
System
The 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.
H010A02O-AAT
Your 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 (V6 Vehicle with Traction Control Sys-
tem)
o To prevent the vehicle from misfiring
during dynamometer testing, discon-
nect the ABS connector in the engine
compartment. (2.7 V6 only)
o For more information, see shop manual
(Wheel Speed Sensor).
o After dynamometer testing is completed,
erase the ABS/TCS DTC (Diagnotic
Trouble Code) with a GST (Generic Scan
Tool) or Hi-Scan Pro.Canister
Fuel vapors generated inside the fuel tank are
absorbed and stored in the 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.
H010C01S-AAT2 . Evaporative Emission Control (Includ-
ing ORVR: Onboard Refueling Vapor
Recovery) System
The 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 of 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.)

3CATALYTIC CONVERTEREGR SYSTEM
!
H010E01Y-AAT
(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.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.
o Remember that your Hyundai dealer is
your best source of assistance.
H020A01A-AAT
All 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:

SNOW TIRES
If you equip your car with snow tires, they should
be the same size and have the same load
capacity as the original tires. Snow tires should
be installed on all four wheels; otherwise, poor
handling may result.
Snow tires should carry 4 psi (28 kPa) more air
pressure than the pressure recommended for
the standard tires on the tire label on the driver's
side of the center pillar , or up to the maximum
pressure shown on the tire sidewall whichever
is less.
Do not drive faster than 75 mph (120 km/h)
when your car is equipped with snow tires.

These pressures were chosen to provide 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:
o Lower-than-recommended tire pressures
cause uneven tread wear and poor handling.
o Higher-than-recommended tire pressures
increase the chance of damage from im-
pacts and cause uneven tread wear.
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.
o Check the pressure of your spare tire
each time you check the pressure of
other tires.o Never overload your car. Be especially
careful about overloading if you equip
your car with a luggage rack or car top
carrier.
CAUTION:!

I050A03A-AAT
TIRE CHAINS
Tire chains, if necessary, should be installed on
the front wheels. Be sure that the chains are
installed in accordance with the manufacturer's
instructions.
To minimize tire and chain wear, do not continue
to use tire chains when they are no longer
needed.
WARNING:o When driving on roads covered with
snow or ice, drive at less than 20 mph (30
km/h).
o Use the SAE "S" class or wire & plastic
chains.
o If you have noise caused by chains con-
tacting the body, retighten the chain to
avoid contact with the vehicle body.
o To prevent body damage, retighten the
chains after driving 0.3 ~ 0.6 miles.

TIRE TRACTION
Tire traction can be reduced if you drive on worn
tires, tires that are improperly inflated or on
slippery road surfaces. Tires should be re-
placed when tread wear indicators appear. To
reduce the possibility of losing control, slow
down whenever there is rain, snow or ice on the
road.
I070A01A-AAT
TIRE BALANCING
A tire that is out of balance may affect handling
and tire wear. The tires on your Hyundai were
balanced before the car was delivered but may
need balancing again during the years you own
the car.
Whenever a tire is dismounted for repair, it
should be rebalanced before being reinstalled
on the car.
I090A01A-AAT
WHEN TO REPLACE TIRES
The original tires on your car have tread wear
indicators. The tread wear indicators appear
when the tread depth is 0.06 in. (1.6 mm). The
tire should be replaced when these appear as
a solid bar across two or more grooves of the
tread. Always replace your tires with those of
the recommended size. If you change wheels,
the new wheel's rim width and offset must meet
Hyundai specification.

TIRE ROTATION
Tires should be rotated every 7,500 miles
(12,000 km). If you notice that tires are wearing
unevenly between rotations, have the car
checked by a Hyundai dealer so the cause may
be corrected.
After rotating, adjust the tire pressures and be
sure to check wheel nut torque.
CAUTION:Do not mix bias-ply and radial-ply under
any circumstances. This may cause dan-
gerous handling characteristics.
