7EMISSION CONTROL SYSTEMS
2EMISSION CONTROL SYSTEM
H010A01A-GAT
(If Installed)
Your Hyundai is equipped with an
emission control system to meet all requirements of the Emission prohibi- tion rules of your province. There are three emission control sys-
tems which are as follows.
1) Crankcase emission control sys- tem
2) Evaporative emission control sys-
tem
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 maintained by an au- thorized Hyundai dealer in accordancewith the maintenance schedule in this manual. H010B01A-AAT
1. Crankcase Emission Control
System
The positive crankcase ventilation
system is employed to prevent airpollution caused by blow-by gases being emitted from the crankcase.This system supplies fresh air to the crankcase through the air intake hose. Inside the crankcase, the fresh airmixes with blow-by gases, which then pass through the PCV valve and into the induction system.
H010C02E-GAT
2. Evaporative Emission
Control System
The Evaporative Emission Control
System is designed to prevent fuelvapors from escaping into the atmo-sphere. 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 can-ister are drawn into the induction sys-tem through the purge control sole- noid valve. Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is
controlled by the Engine Control Mod- ule (ECM); when the engine coolant temperature is low during idling, the PCSV closes so that evaporated fuelis not taken into the engine. After the engine warms-up during ordinary driv- ing, the PCSV opens so as to intro-duce evaporated fuel to the engine. H010D01A-AAT
3. Exhaust Emission Control
System
The exhaust emission control system is a highly effective system which controls exhaust emission while main-taining good vehicle performance.

CATALYTIC CONVERTER
H020A01A-GAT
(If Installed) ; For a gasoline engine
H020A01MC
The catalytic converter is part of the exhaust emission control system. Itspurpose is to remove certain engine emission products from the engine's exhaust. It looks something like amuffler and is located underneath the car in the exhaust system.
Catalytic Converter H020B02A-GAT
About the Catalytic Converter
Exhaust gases passing through the
catalytic converter cause it to operate at very high temperatures. As a re- sult, the introduction of large amountsof unburned gasoline may cause it to overheat and create a fire hazard. This can be avoided by observing thefollowing:
WARNING:
o Make sure to refuel your vehicle according to the "Fuel recom- mendations" suggested in sec- tion 1.
o Maintain your engine in good condition. Extremely high con-verter temperatures can result from improper operation of the electrical, ignition or fuel injec-tion systems.
o If your engine stalls, pings,
knocks, or is hard to start, takeyour car to your Hyundai dealer as soon as possible and have the difficulty corrected.
o Avoid driving with a very low fuellevel. If your run out of gasoline, it could cause the engine to mis- fire and result in excessive load- ing of the catalytic converter.
o Avoid idling the engine for peri-
ods longer than 10 minutes.
o Your Hyundai should not be ei- ther pushed or pulled to get itstarted. This can cause the cata-lytic converter to overload.
o Take care not to stop your Hyundai over any combustible material such as grass, paper, leaves or rags. As these materials couldcome in contact with the catalytic converter and could cause a fire.
o Do not touch the catalytic con- verter or any other part of theexhaust system while the en- gine is running as it is very hotand could result in burns.
o Remember that your Hyundai dealer is your best source of as- sistance.

4EGR SYSTEM
H020C01S-GAT
(If Installed) ; For a diesel engine
This system helps control oxides of nitrogen by recirculating a part of the exhaust gas into the engine.
H020D01S-GAT
CATALYTIC CONVERTER (If Installed); For a diesel engine
Hyundai vehicle is equipped with oxi-
dation type catalytic converter to re- duce the carbon monoxide, hydrocar- bons and particulate contained in theexhaust gas.
o Do not park, idle or drive your vehicle over any combustible ma- terial such as grass, paper, leaves or rags. These materials might contact the hot catalytic converterand a fire might result.

2VEHICLE IDENTIFICATION NUMBER (VIN)
I010A02MC-AAT The vehicle identification number (VIN) is the number used in registering yourcar and in all legal matters pertaining to its ownership, etc. It can be found in four different places on your car (IfInstalled):
1. The number is punched on floor un-
der 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. Thenumber on the plate can easily be seen through the windshield fromoutside.
3. The vehicle certification label at-
tached on the driver's side centerpillar gives the vehicle identification number (VIN).
4. On the lower side of the center pillar outer panel.

I040A02S-GAT SNOW TIRES If you equip your car with snow tires, they should be the same size and havethe same load capacity as the original tires. Snow tires should be installed on all four wheels; otherwise, poor han-dling may result. Snow tires should carry 28 kPa (4 psi) more air pressure than the pressurerecommended for the standard tires on the tire label on the driver's door edge, or up to the maximum pressure shownon the tire sidewall whichever is less. Do not drive faster than 120 km/h (75 mph) when your car is equipped withsnow tires.
These pressures were chosen to pro-vide the most satisfactory combinationof ride comfort, tire wear and stability under normal conditions. Tire pres- sures should be checked at leastmonthly. Proper tire inflation pressures should be maintained for these rea- sons:
o Lower-than-recommended tire pres-
sures cause uneven tread wear and poor handling.
o Higher-than-recommended tire
pressures increase the chance ofdamage from impacts 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 threehours and hasn't been driven more than 1.6 km or one mile since starting up.
o Check the pressure of your spare tire each time you check the pres-sure of other tires.
o Worn, old tires can cause acci-
dents. If your tread is badly worn, or if your tires have been dam-aged, replace them.
