EMISSION CONTROL 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 induction sys-
tem through the purge control solenoid
valve.Purge Control Solenoid Valve (PCSV)The purge control solenoid valve is con-
trolled by the Engine Control Module
(ECM); when the engine coolant tem-
perature 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.
H010B01A-AAT1. Crankcase Emission Control
SystemThe positive crankcase ventilation sys-
tem is employed to prevent air pollution
caused by blow-by gases being emitted
from the crankcase. This system supplies
filtered fresh air to the crankcase through
the air intake hose. Inside the crankcase,
the fresh air mixes with blow-by gases,
then passes through the PCV valve into
the induction system.
H010A01A-AATYour Hyundai is equipped with an emis-
sion control system to meet all require-
ments of the U.S. Environmental Protec-
tion Agency or California 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 recom-
mended that you have your car inspected
and maintained by an authorized Hyundai
dealer in accordance with the mainte-
nance schedule in this manual.
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
vapors into the atmosphere.)

H010D02A-AAT3. Exhaust Emission
Control SystemThe Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions while maintaining
good vehicle performace.
H020A03A-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:
H020A01MC
Catalytic Converter
WARNING:
o Use unleaded fuel only.
o Maintain the engine in good operat-
ing condition. Extremely high cata-
lytic converter temperatures can re-
sult from improper operation of the
electrical, ignition or multiport elec-
tronic fuel injection.
o If your engine stalls, pings, knocks,
or is hard to start, have your Hyundai
dealer inspect and repair the prob-
lem as soon as possible.
o Avoid driving with a very low fuel
level. Running out of gasoline may
cause the engine to misfire and re-
sult in damage to the catalytic con-
verter.
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.

CALIFORNIA PROPOSITION 65
WARNING:
Engine exhaust and a wide variety of
automobile components and parts, in-
cluding components found in the inte-
rior furnishings in a vehicle, contain or
emit chemicals known to the State of
California to cause cancer and birth
defects and reproductive harm. In addi-
tion, certain fluids contained in vehicles
and certain products of component
wear contain or emit chemicals known
to the State of California to cause can-
cer and birth defects or other repro-
ductive harm.

WARNING:
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 park, idle or drive your ve-
hicle over any combustible material
such as grass, paper, leaves or rags.
These materials might contact the
hot catalytic converter and a fire
might result.

VEHICLE IDENTIFICATION
NUMBER (VIN)I010A02MC-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 four
different places on your car:
1. The number is punched on floor under
the front passenger seat. To check the
number, remove the cover.
2. The VIN is also on a plate attached to
the top of the dashboard. The number
on the plate can easily be seen through
the windshield from outside.
3. The vehicle certification label attached
on the driver's side center pillar gives
the vehicle identification number (VIN).
4. On the lower side of the center pillar
outer panel.

These pressures were chosen to pro-
vide the most satisfactory combina-
tion 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 rea-
sons:
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 ve-
hicle 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 8-12.
o Remember to check the pressure
of your spare tire. Hyundai rec-
ommends that you check the
spare every time you check the
pressure of the other tires on
your vehicle.
WARNING:
Overinflation or underinflation can
reduce the tire life, adversely affect
vehicle handling, and lead to sud-
den tire failure. This could rusult in
loss of vehicle control and potential
injury.CAUTION:
Always observe the following:
o Check pressures when the tires
are cold. (After the vehicle has
been parked for at least three
hours or hasn't been driven more
than one mile (1.6 km) since start-
ing up.)
o Check the pressure of your spare
tire each time you check the pres-
sure of other tires.
o Never overload your vehicle. Be
especially careful about overload-
ing if you equip your vehicle with
a luggage rack.
o Worn, old tires can cause acci-
dents. If your tread is badly worn,
or if your tires have been dam-
aged, replace them.
!
WARNING:NOTE:
o Underinflation also results in ex-
cessive wear, poor handling and
reduced fuel economy. Wheel de-
formation also is possible. Keep
your tire pressures at the proper
levels. If a tire frequently needs
refilling, have it checked by your
Hyundai Dealer.
o Overinflation produces a harsh
ride, excessive wear at the center
of the tire tread, and a greater
possibility of damage from road
hazards.

If you overfill the tire, release air by
pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gauge. Be
sure to put the valve caps back on the
valve stems. They help prevent leaks
by keeping out dirt and moisture.
Federal law requires tire manufactur-
ers to place standardized information
on the sidewall of all tires. This infor-
mation identifies and describes the
fundamental characteristics of the tire
and also provides the tire identification
number (TIN) for safety standard cer-
tification. The TIN can be used to
identify the tire in case of a recall.

I035A01JM-AATCHECKING TIRE INFLATION PRES-
SURE
Check your tires once a month or
more. Also, check the tire pressure of
the spare tire.
How to Check
Use a good quality gauge to check tire
pressure. You can not tell if your tires
are properly inflated simply by looking
at them. Radial tires may look properly
inflated even when they're underinflated.
Check the tire's inflation pressure when
the tires are cold. - "Cold" means your
vehicle has been sitting for at least
three hours or driven no more than 1
mile (1.6 km).
Remove the valve cap from the tire
valve stem. Press the tire gauge firmly
onto the valve to get a pressure mea-
surement. If the cold tire inflation pres-
sure matches the recommended pres-
sure on the tire and loading information
label, no further adjustment is neces-
sary. If the pressure is low, add air
until you reach the recommended
amount.
