7- 2 EMISSION CONTROL SYSTEMS
H010A01A-GAT
EMISSION CONTROL SYSTEM (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 accordance with 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 gasesbeing emitted from the crankcase. This system supplies fresh 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 intothe induction system.
H010C02Y-GAT
2. Evaporative Emission
Control System
The Evaporative Emission Control
System is designed to prevent fuel vapors from escaping into the atmo- sphere. Canister
While the engine is inoperative, fuel
vapors generated inside the fuel tank are absorbed and stored in the canis- ter. When the engine is running, the fuel vapors absorbed in the canisterare drawn into the induction system through the purge control solenoidvalve. Purge Control Solenoid Valve
The purge control solenoid valve is
controlled by the ECM; when the en- gine coolant temperature is low, and during idling, it closes, so that evapo- rated fuel is not taken into the surgetank. After engine warm-up, during ordinary driving, it opens so as to introduce evaporated fuel to the surgetank.
H010D01A-AAT
3. Exhaust Emission Control
System
The exhaust emission control system
is a highly effective system whichcontrols exhaust emission while main- taining good vehicle performance.
H010E01Y-GAT
EGR System
This system helps control nitrogen
oxides by recirculating a part of the exhaust gas into the engine, therebyreducing cylinder combustion tem- perature.

EMISSION CONTROL SYSTEMS 7- 3
WARNING:
o Use unleaded fuel only.
o Maintain the engine in good operating condition. Extremelyhigh catalytic converter tempera- tures can result from improper operation of the electrical, igni-tion or multiport electronic fuel injection.
o If your engine stalls, pings, knocks, or is hard to start, haveyour Hyundai dealer inspect and repair the problem as soon as possible.
o Avoid driving with a very low fuel level. Running out of gaso-line may cause the engine to misfire and result in damage tothe catalytic converter.
o Avoid idling the engine for peri- ods longer than 10 minutes.
o The vehicle should not be pushed or pulled to get started.This may cause the catalytic con- verter to overheat and create a fire hazard.
H020A01A-AAT
CATALYTIC CONVERTER
HXGS509
All Hyundai vehicles are equippedwith a monolith type three-way cata-lytic converter to reduce the carbon monoxide, hydrocarbons and nitro- gen oxides contained in the exhaustgas. Exhaust gases passing through the catalytic converter may 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 tooverheat and create a fire hazard. This risk may be reduced by observ- ing the following:
Catalytic Converter o Do not touch the catalytic con-
verter or any other part of the exhaust system while the cata-lytic 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.
o Remember that your Hyundai dealer is your best source of assistance.
o Do not stop your Hyundai over any combustible material suchas grass, paper, leaves or rags.These materials might contact the hot catalytic converter and a fire might result.

Engine Number
I010A01A-GAT VEHICLE IDENTIFICATION NUM- BER (VIN) The vehicle identification number (VIN) is the number used in register-ing your car and in all legal matters pertaining to its ownership, etc. It can be found on the identification plate attached to the engine side of the firewall between the engine andpassenger compartment.
The engine number is stamped on
the engine block as shown in the drawing. I020A01A-AAT
TIRE INFORMATION
The tires supplied on your new
Hyundai are chosen to provide thebest performance for normal driving.
I030A01L-GAT
RECOMMENDED INFLATION PRESSURES
The tire label located on the driver's
door edge gives the tire pressures recommended for your car.

CONSUMER INFORMATION 8- 3
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 thepressure of other tires.
o Never overload your car. Be es- pecially careful about overload-ing if you equip your car with a luggage rack or car top carrier. I040A01S-GAT 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 beinstalled on all four wheels; other- wise, poor handling may result. Snow tires should carry 28 kPa (4 psi) more air pressure than the pres- sure recommended for the standard tires on the tire label on the driver'sdoor edge, or up to the maximum pressure shown on the tire sidewall whichever is less.Do not drive faster than 120 km/h (75mph) when your car is equipped withsnow tires.

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 reasons:
o Lower-than-recommended tire pressures cause uneven tread wear and poor handling.
o Higher-than-recommended tire pressures increase the chance ofdamage from impacts and causeuneven tread wear.

8- 4 CONSUMER INFORMATION
I060A01Y-GAT TIRE ROTATION Tires should be rotated every 10,000 km (6,000 miles). 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 pres-sures and be sure to check wheel nuttorque. HA1409
Spare tire WARNING:
Do not mix bias-ply and radial-ply
tires under any circumstances. This may cause dangerous handlingcharacteristics that may cause death, serious injury, or property damage.
!
I070A01A-AAT TIRE BALANCING A tire that is out of balance may affect handling and tire wear. The tires on your Hyundai were balanced beforethe 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.
I050A02Y-GAT
TIRE CHAINS
Tire chains 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 whenthey are no longer needed.!WARNING:
When driving on roads covered with snow or ice, drive at less than30 km/h (20 mph).

CONSUMER INFORMATION 8- 5
I100A01FC-GAT SPARE TIRE AND TOOLS Your Hyundai is delivered with the following: Spare tire and Wheel Wheel nut wrench, Wrench bar, Spanner, Screwdriver Jack I100A03L
The original tires on your car have tread wear indicators. The tread wear indicators appear when the treaddepth is 1.6 mm (0.06 in.). The tire should be replaced when these ap- pear as a solid bar across two ormore grooves of the tread. Always replace your tires with those of the recommended size. If you changewheels, the new wheel's rim width and offset must meet Hyundai speci- fications.
!
I080A01A-AAT
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 replacedwhen tread wear indicators appear. To reduce the possibility of losing control, slow down whenever there israin, snow or ice on the road.
I090A01Y-GAT
WHEN TO REPLACE TIRES
Wear indicator
1.6 mm (0.06 in.)
HGK248WARNING:
o Driving on worn-out tires is dan- gerous! Worn-out tires can cause loss of braking effective- ness, steering control and trac-tion. When replacing tires, never mix radial and bias-ply tires on the same car. If you replace ra-dial tires with biasply tires, they must be installed in sets of four.
o Using tires and wheels of other than the recommended sizesmay cause unusual handling characteristics that may causedeath, serious injury, or prop- erty damage.
