EMISSION CONTROL SYSTEM
3CATALYTIC CONVERTER
H040A01P-GAT 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 canister are drawn into the induction systemthrough the purge control solenoid valve. H090A01P-GAT Purge Control Solenoid Valve The purge control solenoid valve is controlled by the ECU; 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. H050A01P-GAT
3. Exhaust Emission Control
System
The Exhaust Emission Control Sys-
tem is a highly effective system which controls exhaust emission while main-taining good vehicle performance. H060A01P-GAT All Hyundai vehicles are equipped with a monolith type three-way cata- lytic converter to reduce the carbonmonoxide, hydrocarbons and nitrogen oxides contained in the exhaust gas.

A translucent coolant reservoir tank is
in the engine compartment.
The coolant level in this tank should
be kept between the "L" and "F" marks when measured while the engine iswarm and idling.
The cooling system is a closed sys-
tem and normally the loss of coolant should be very slight. A noticeable drop in the coolant level could indi-cate leakage. If this occurs, have the system
checked at an authorized HYUNDAIdealer as soon as possible. If the level should drop below the "L"
level on the reservoir tank, add cool- ant.
Also, if the reservoir tank is com-
pletely empty, remove the radiatorcap and add coolant until the level reaches the filler neck.
!WARNING:
Do not open the reservoir tank lid
or radiator cap while the engine is hot. The coolant system is under pressure and any hot coolant es-caping could cause severe burns. G050B01A-AAT Recommended Engine Coolant Use a high quality ethylene-glycol coolant in a 50/50 mix with water. The engine coolant should be compatible with aluminum engine parts. Addi-tional corrosion inhibitors or additives should not be used. The cooling sys- tem must be maintained with the cor-rect concentration and type of engine coolant to prevent freezing and corro- sion. Never allow the concentration ofantifreeze to exceed the 60% level or go below the 35% level, or damage to the cooling system may result. Forproper concentration when adding or replacing the engine coolant, refer to the following table.

Antifreezesolution G050C01A-GAT To Check the Coolant Level The coolant level can be seen on the side of the plastic coolant reservoir. The level of the coolant should be between the "L" and "F" lines on thereservoir when the engine is cold. If the level is below the "L" mark, add engine coolant to bring it up between"L" and "F". If the level is low, inspect for coolant leaks and recheck the fluid level frequently. If the level dropsagain, visit your Hyundai dealer for an inspection and diagnosis of the rea- son.

4. Turn the radiator cap counterclock-
wise without pressing down on it, until it stops. This relieves any pres- sure remaining in the cooling sys- tem. And remove the radiator capby pushing down and turning coun- terclockwise. Now fill the radiator with clean dem- ineralized or distilled water. Con- tinue to add clean demineralized or distilled water in small quantitiesuntil the fluid level stays up in the radiator neck.
5. Start the engine, top off the radia- tor with water and then add engine coolant to the reservoir until thelevel is between "L" and "F".
6. Replace the radiator and reservoir caps and check to be sure thedrain cocks are fully closed and not leaking. WARNING:
The cooling fan is controlled by
engine coolant temperature andmay sometimes operate even when the engine is not running. Useextreme caution when working near the blades of the cooling fan so that you are not injured by a rotat-ing fan blade. As the engine cool- ant temperature decreases, the fan will automatically shut off. This isa normal condition.
G050D02P-AAT To Change the Coolant The coolant should be changed at those intervals specified in the ve- hicle maintenance schedule in Sec- tion 6.
!
CAUTION:
Engine coolant can damage the finish of your car. If you spill en-gine coolant on the car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the parking brake and remove the radiator cap when cool.
2. Be sure your drain receptacle is in
place. Open the drain cock on theradiator. Allow all the engine cool- ant to drain from the cooling sys- tem, then securely close the draincock.
3. Check Section 9 for the capacity of the cooling system in your car.Then, following the manufacturer's directions on the engine coolant container, add the appropriatequantity of coolant to the radiator.

FILLING THE WASHER RESERVOIR
I130A01P-GAT The washer fluid reservoir supplies
fluid to the windshield washer sys- tem.
A good quality washer fluid should be
used to fill the washer reservoir. Thefluid level should be checked more frequently during bad weather or whenever the washer system is inmore frequent use.
!WARNING (Diesel only):
Never work on injection system with engine running or within 30 seconds after shutting off engine.High pressure pump, rail, injec- tors and high pressure pipes are subject to high pressure even af-ter the engine stopped. The fuel jet produced by fuel leaks may cause serious injury, if it touch the body.People using pacemakers should not move than 30cm closer to the ECU or wiring harness within theengine room while engine is run- ning, since the high currents in the Common Rail system produceconsiderable magnetic fields.
