B010A01O-GAT FUEL RECOMMENDATIONS Use Unleaded Gasoline Unleaded gasoline with a Pump Octane Rating of 87 (Research Octane Number 91) or highermust be used in Hyundai vehicle. If leadedgasoline is used, it will cause the catalyticconverter to become ineffective and the emis-sion control system to malfunction. This canalso result in increased maintenance expense.To avoid accidental use of leaded fuel, the largenozzle used with leaded gasoline at servicestations can not be inserted into fuel tankopening of Hyundai vehicle. NOTE:
o For some countries, Hyundai vehicles
are designed to use leaded gasoline.When you are going to use leaded gaso-line, ask to Hyundai dealer whether leadedgasoline in your vehicle is available ornot.
o Octane Rating of leaded gasoline is same with unleaded one.
Use Diesel Diesel fuel of 52 to 54 cetane is used in Hyundai vehicle. If two types of diesel fuel are available,
use summer or winter fuel properly according tothe following temperature conditions.
o Above -5°C (23°F) ... Summer type diesel fuel.
o Below -5°C (23°F) ... Winter type diesel fuel.Watch the fuel level in the tank very carefully : If the engine stops through fuel failure, thecircuits must be completely purged to permitrestarting. CAUTION:
o Do not let any gasoline or water enter the tank. This would make it necessary todrain it out and to bleed the lines to avoidjamming the injection pump and damag-ing the engine.
o In winter, in order to cut down incidents due to freezing, paraffin oil may be addedto the fuel if the temperature drops tobelow -10°C. Never use more than 20%paraffin oil. B010B01A-AAT What About Gasohol?Gasohol (a mixture of 90% unleaded gasoline and 10% ethanol or grain alcohol) may be usedin your Hyundai. However, if your engine devel-ops driveability problems, the use of 100%unleaded gasoline is recommended. Fuels withunspecified quantities of alcohol, or alcoholsother than ethanol, should not be used. B010E01A-AAT Gasolines for Cleaner Air To help contribute to cleaner air, Hyundai rec- ommends that you use gasolines treated withdetergent additives, which help prevent depositformation in the engine. These gasolines willhelp the engine run cleaner and enhance per-formance of the Emission Control System.
B010D01S-AAT Do not Use Methanol Fuels containing methanol (wood alcohol) should not be used in your Hyundai. This typeof fuel can reduce vehicle performance anddamage components of the fuel system. CAUTION: Your Hyundai's New Vehicle Limited War-
ranty may not cover damage to the fuelsystem and performance problems that are
caused by the use of methanol or fuelscontaining methanol.

WARNING: Never remove the radiator cap when theengine is hot. The engine coolant is underpressure and could erupt and cause severeburns. Wait until the engine is cool beforeremoving the radiator cap. The needle on the engine coolant temperature gauge should stay in the normal range. If itmoves across the dial to "H" (Hot), pull over andstop as soon as possible and turn off theengine. Then open the hood and after theengine has cooled, check the coolant level andthe water pump drive belt. If you suspect cool-ing system trouble, have your cooling systemchecked by a Hyundai dealer as soon as pos-sible.
The needle on the gauge indicates the approxi-mate fuel level in the fuel tank. The fuel capacityis given in Section 9.

H010A01A-GAT
EMISSION CONTROL SYSTEMS (If Installed)
Your Hyundai is equipped with an emission
control system to meet all requirements of the Emission prohibition rules of your province. 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 thismanual. H010D01A-AAT
3. Exhaust Emission Control System
The Exhaust Emission Control System is a
highly effective system which controls exhaustemissions while maintaining good vehicle per-formance.
H010C01E-GAT
2. Evaporative Emission Control
System
The Evaporative Emission Control System is
designed to prevent fuel vapors from escapinginto the atmosphere. Canister
While the engine is inoperative, fuel vapors
generated inside the fuel tank are absorbed and stored in the canister. When the engine isrunning, the fuel vapors absorbed in the canis-ter 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 theengine coolant temperature is low during idling,the PCSV closes so that evaporated fuel is nottaken into the engine. After the engine warms-up during ordinary driving, the PCSV opens soas to introduce evaporated fuel to the engine. H010B01A-AAT
1. Crankcase Emission Control
System
The Positive Crankcase Ventilation System is
employed to prevent air pollution caused byblow-by gases being emitted from the crank-case. This system supplies fresh filtered air tothe crankcase through the air intake hose.Inside the crankcase, the fresh air mixes withblow-by gases, then passes through the PCVvalve into the induction system.
The catalytic converter is part of the exhaust
emission control system. Its purpose is to re-move certain engine emission products fromthe engine's exhaust. It looks something like amuffler and is located underneath the car in the
exhaust system.

Engine Coolant Level
SG050D1-E
To Change the Engine Coolant The engine coolant should be changed at
those intervals specified in the vehicle main- tenance schedule in Section 5.
NOTE:Care should be taken to ensure that cool-
ant is not allowed to spill onto thepaintwork since the finish may becomedamaged. If coolant spillage occurs, theaffected area should be rinsed thoroughlywith water. The engine coolant level may be observed
through the side of the plastic coolant reservoir(expansion tank) when the engine is cold. If thelevel is below the "LOW" mark, add coolant ofthe correct concentration until the level is be-tween the "LOW" and "Full" marks. If the levelfalls below the "LOW" mark on a regular basisdespite being topped up, consult a Hyundaidealer. 1. Park the vehicle on level ground and en-
sure that the parking brake is firmly ap-plied, and the engine allowed to cool. DO NOT ATTEMPT THIS OPERATION WHILST THE ENGINE IS HOT SINCEBURNING OR SCALDING MAY RESULT.
2. Prepare a suitable receptacle to collect the displaced coolant and position this under theradiator drain tap.
3. With the heater temperature control set to the "HOT" position, remove the radiator capand open the radiator drain tap.
4. When the engine coolant has drained com- pletely, close the drain tap ensuring that thisis not over tightened.
5. Prepare a suitable quantity of new engine coolant (refer to section 9) and pour thisinto the radiator.
6. Start the engine with the radiator cap still removed and continue to add coolant as thelevel decreases as air is expelled from thesystem. When the level remains constant,replace the radiator cap and replenish thecoolant reservoir.
7. When the engine is hot, check to ensure that no coolant leaks are present.
WARNING: The cooling fan is controlled by engine coolant temperature and may sometimesoperate even when the engine is not run-ning. Use extreme caution when workingnear the blades of the cooling fan so that

7. EMISSION
CONTROL SYSTEM
SH010A1-E EMISSION CONTROL SYSTEMS (Not all models) Depending upon the market for which the ve-hicle is destined, the emission control systemwill comprise one or more of the followingemission control devices. (1) Crankcase emission control system (2) Evaporative emission control system (3) Exhaust emission control system In order that the proper functioning of the emis- sion control systems may be ensured, it isrecommended that the vehicle is inspected andmaintained by an authorized Hyundai dealer inaccordance with the maintenance schedule inthis manual. SH010B1-E 1. CRANKCASE EMISSION CONTROL SYSTEM
The positive crankcase ventilation system is employed to prevent air pollution caused byblow-by gases being emitted from the crank-case by introducing fresh air to the crankcase through the air cleaner where this mixes withblow-by gases and then passes through thePCV valve into the intake manifold from whereit subsequently enters the combustion cham-ber and is burned.
SH010D1-E 3. EXHAUST EMISSION CONTROL SYSTEM The exhaust emission control system is a highlyeffective system which controls exhaust emis-sion while maintaining good vehicle perfor-mance.
SH010C1-E
2. EVAPORATIVE EMISSION
CONTROL SYSTEM
The Evaporative Emission Control System is designed to prevent fuel vapours from escap-ing into the atmosphere through the fuel tankventilation system.Whilst the engine is not running, fuel vapoursgenerated inside the fuel tank are absorbedand stored in a charcoal canister. When theengine is started, the vapours stored in thecanister are drawn into the induction systemthrough the purge control solenoid valve andare subsequently burned.The purge control solenoid valve is controlledby the ECU; when the engine coolant tempera-ture is low or the engine is idling, the purgecontrol valve is closed and fuel vapours remainstored in the canister. Under normal runningconditions when the engine is warm, the valveopens and the vapours are drawn into the inlettract and subsequently burned in the combus-tion chamber. SH020A1-E
Catalytic Convertor Operation Precautions; For a gasoline engine Hyundai Matrix models are fitted with catalytic convertors which require special operatingconsiderations. The catalytic convertor servesto oxidize certain noxious elements of theexhaust gases leaving the engine to reduce thelevel of pollutants emitted from the vehicle and,provided that care is exercised to prevent dam-age, the catalyst will operate efficiently for thelife of the vehicle.
