2EMISSION CONTROL SYSTEM
H010D01A-AAT3. 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 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 and into the induction system.
H010A01A-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 ensure 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.Canister
Fuel 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
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
(Including 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 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.)

7EMISSION CONTROL SYSTEMS
3CATALYTIC 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.
o Remember that your Hyundai dealer is
your best source of assistance.
H020A01S-AAT
All Hyundai vehicles are equipped with one or
two monolith type three-way catalytic convert-
ers to reduce the carbon monoxide, hydrocar-
bons and nitrogen oxides contained in the ex-
haust 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:
WARNING: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.

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
side center pillar outer panel, 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.
I030A02S-AAT
RECOMMENDED INFLATION
PRESSURES
The tire label located on the driver's side center
pillar outer panel gives the tire pressures rec-
ommended for your vehicle.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.

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 the wheel nut torque.
WARNING:o Do not use the temporary spare tire for
tire rotation.
o Do not mix bias ply and radial ply tires
under any circumstances. This may
cause unusual handling characteristics
that could result in death, serious injury,
or property damage.

I050A01S-AAT
TIRE CHAINS
Tire chains, if necessary, should be installed on
the front wheels. Be sure that the chains are the
proper size and that they are installed in accor-
dance 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:When driving on roads covered with snow
or ice, drive at less than 20 mph (30 km/h).

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.
WARNING:o Driving on worn-out tires is dangerous!
Worn-out tires can cause loss of braking
effectiveness, steering control and trac-
tion. When replacing tires, never mix
radial and bias ply tires on the same car.
If you replace radial tires with bias-ply
tires, they must be installed in sets of
four.
o Using tires and wheels of other than the
recommended sizes could cause un-
usual handling characteristics that could
cause death, serious injury, or property
damage.
o Wheels that do not meet Hyundai's di-
mensional specifications may fit poorly
and result in damage to the vehicle,
including broken wheel studs.

Department of Transportation quality grades -
All passenger vehicle tires must conform to
Federal Safety Standards in addition to these
grades. These quality grades are molded on the
sidewall.
Treadwear - The tread wear grade is a com-
parative rating based on the wear rate of the tire
when tested under controlled conditions on a
specified government test course. For example,
a tire graded 150 would wear one and a half (1
- 1/2) times as well on the government course
as a tire graded 100. The relative performance
of tires depends upon the actual conditions of
their use, however, and may depart significantly

service practices and differences in road char-
acteristics and climate.
Traction AA, A, B, C - The traction grades, from
highest to lowest, are AA, A, B, and C. Those
grades represent the tire's ability to stop on wet
pavement as measured under controlled con-
ditions on specified government test surfaces
of asphalt and concrete. A tire marked C may
have poor traction performance.
WARNING:The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
Temperature A, B, C - The temperature grades
are A (the highest), B, and C, representing the
tire's resistance to the generation of heat and
its ability to dissipate heat when tested under
controlled conditions on a specified indoor labo-
ratory test wheel. Sustained high temperature
can cause the material of the tire to degenerate
and reduce tire life, and excessive temperature
can lead to sudden tire failure. The grade C
corresponds to a level of performance which all
