7EMISSION CONTROL SYSTEM
2EMISSION CONTROL SYSTEM
H010A01P-GAT (Gasoline) Your Hyundai is equipped with an emission control system. 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 systemIn order to assure the proper function of the emission control systems, it is recommended that you have your vehicle inspected and maintained byan authorized Hyundai dealer in ac- cordance with the maintenance sched- ule in this manual. H020A01P-GAT
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 cleaner. Inside the crankcase, the fresh airmixes with blow-by gases, then passes through the PCV valve into the induction system.
H080A01P-GAT PCV Valve The crankcase ventilation system must be kept clean to maintain good engine performance. Periodic servicing is required to re- move combustion products from the PCV valve. H030A01P-GAT
2. Evaporative Emission Control
System (except canister)
The Evaporative Emission ControlSystem is designed to prevent fuel vapors from escaping into the atmo-sphere.If the fuel-vapor vent line is cloggedor damaged, the fuel-vapor mixturewill escape into the atmosphere and cause insufficient emission control. Disconnect the line at both ends, and blow it clean with compressed air. Remove the filler cap from the filler pipe, and check to see if there is evidence that the packing contact to the filler pipe is faulty. The overfilllimiter (2-way valve) installed on the vapor line between the canister inlet and fuel tank outlet must be checkedfor correct operation.

7CHECKING THE ENGINE OIL
If you notice anything that does not
operate correctly or appear to be func- tioning correctly, inspect it carefully and seek assistance from your Hyundai dealer if service is needed.
Adequate care of your vehicle at regu-
lar intervals serves to preserve thevalue and appearance as long aspossible.
Some maintenance items can be car-
ried out by the owner (Consumer Information), while other should be done only by an authorized dealer(Periodic Inspection and Mainte- nance). This section describes only those items which can be carried outby the owner. In the event a malfunc- tion or other problem is discovered, have it corrected by an authorizedHYUNDAI dealer. This section con- tains information on inspection main- tenance procedures that you can doyourself, if you so desire. Follow the instructions and cautions for each of the various procedures. When checking or servicing the in-side of the engine compartment, besure the engine is stopped and has had a chance to cool down. If it is necessary to do work in the enginecompartment with the engine running, be especially careful that your cloth- ing, hair, etc., becomes not caught bythe fan, V-belts, or other moving parts.
I070A06P-GAT Recommended Oil Diesel Engine

To Check the Oil Level
If the oil level is below the specified limit, remove the cap located on the cylinder head cover and add enoughoil to raise the level to within the specified range. Be sure to use the specified engine oil and do not mixvarious types of oil. Also, avoid mix- ing different makes of oil together if possible. After adding oil, close thecap securely.
It is important to check the oil level at
regular intervals or before starting a long trip.
This check must be made with the
engine warm but not running. Park the vehicle on a level surface, stopthe engine, and then wait a few mo- ments to allow the engine oil in circu- lation to return to the oil pan to ensureaccurate measurement. Remove the dipstick and wipe it with a clean cloth. Reinsert the dipstick and read the oillevel, which should always be within the range indicated in the figure. WARNING:
Be careful not to touch the hot exhaust manifold.
CAUTION:
Slowly pour the recommended oilusing by a funnel. Do not overfillnot to damage engine. NOTE: Check the oil level on the dipstick once again after adding the oil.

10CHECKING THE ENGINE COOLANT
G350A01A-GAT ENGINE OIL CONSUMPTION Function of Engine Oil Engine oil has the primary function of lubricating and cooling the inside of the engine. Engine oil consumption It is normal that an engine should consume some engine oil while nor- mal driving. The cause of oil con- sumption in a normal engine are asfollows;
o Engine oil is used to lubricate pis-
tons, piston rings and cylinders. A thin film of oil is left on the cylinder wall when a piston moves downwards in the cylinder. High negative pressure generated dur-ing engine operation sucks some of the oil into the combustion cham- ber.This oil with some oil of the cylin-der wall is burned by the high tem-perature combustion gases during the combustion process. o The engine oil consumption is
strongly effected by the viscosity and quality of oil, engine rpm and driving condition etc. The engine oil is more consumed under severedriving conditions such as high speeds and frequent acceleration and deceleration than normal driv-ing condition. I080A02P-GAT
!WARNING:
Do not remove the radiator cap
when the engine is hot. When the engine is hot, the engine coolant is under pressure and may erupt through the opening if the cap isremoved. You could be seriously burned if you do not observe this precaution. Do not remove theradiator cap until the radiator is cool to the touch.

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.
Water

35%40%50%60%
Ambient
temperature °C ( °F)-15 (5)
-25 (-13) -35 (-31)-45 (-49) Engine coolant concentration
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.
