CHANGING THE OIL AND FIL- TER tion 5. If the car is being driven in severe conditions, more frequent oil and filter changes are required. The procedure for changing the oil and filter is as follows:
1. Park the car on level ground and
set the parking brake. Start the engine and let it warm up until the needle on the coolant temperaturegauge moves above the lowest mark. Turn the engine off and place the gear selector lever in "P" (auto-matic) or reverse gear (manual transaxle).
2. Open the hood and remove the engine oil filler cap.
3. Slide underneath the car and loosen the drain plug by turning it counter-clockwise with a wrench of the proper size. Be sure that a drainpan is in position to catch the oil as it drains out, then remove the drain plug.

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 as follows;
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.
!
The distance between the "F" and "L" marks is equal to about 1 liter of oil.
WARNING:
Be very careful when draining the engine oil as it may be hot enough to burn you!
o The engine oil consumption is
strongly effected by the viscosity and quality of oil, engine rpm anddriving condition etc. The engine oil is more consumed under severe driving conditions such as highspeeds and frequent acceleration and deceleration than normal driv- ing condition.
The engine oil and filter should be
changed at those intervals specifiedin the maintenance schedule in Sec-

G050D02A-AAT To Change the Engine Coolant The engine coolant should be changed at those intervals specified in the ve- hicle maintenance schedule in Sec-tion 5.
CAUTION:
Engine coolant can damage thefinish 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 coolant to drain from the cooling system,then securely close the drain cock.
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 of an-
tifreeze to exceed the 60% level or gobelow the 35% level or damage to thecoolant system may result. For proper concentration when adding or replac- ing the engine coolant, refer to thefollowing table.

Replacing the Spark Plugs
The spark plugs should be changed
at the intervals specified in the ve- hicle maintenance schedule in Sec- tion 5 or whenever engine perfor- mance indicates they should bechanged. Symptoms that suggest poor spark plug performance include en- gine misfiring under load, loss of fueleconomy, poor acceleration, etc. When spark plugs are replaced, al- ways use spark plugs recommendedby Hyundai. The use of other spark plugs can result in loss of perfor- mance, radio interference or enginedamage.
NOTE:
o When replacing the spark plug, Genuine Hyundai ReplacementParts are recommended. Recommended Spark Plugs:
NOTE: Do not clean or regap platinum- tipped spark plugs.
o Spark plugs should be tightenedfirmly. Overtightening can dam- age the threads in the aluminum cylinder head. Also, leaving themtoo loose can cause the spark plug to get very hot and possi- bly result in damage to the en-gine.
o It is recommended that spark plugs be changed by an autho-rized Hyundai dealer.

Checking the Brake Fluid Level
WARNING:
Use caution when handling brakefluid. It can damage your vision if it gets into your eyes. It will alsodamage your vehicle's paint if spilled on it and not removed im- mediately.
3. If the transaxle fluid level is low,
use a funnel to add transaxle fluidthrough the dipstick tube until the level reaches the "HOT" range. Do not overfill.
WARNING:
The cooling fan is controlled by
engine coolant temperature andmay sometimes operate even whenthe engine is not running. Use extreme caution when working near the blades of the cooling fan,so that you are not injured by a rotating fan blade. As the engine coolant temperature decreases, thefan will automatically shut off. This is a normal condition.
While the engine is idling, apply the
brakes and move the gear selector lever from "P" to each of its otherpositions -- "R", "N", "D" -- and then return to "N" or "P" with the engine still idling:
1. Open the hood, being careful to
keep hands, long hair and clothing clear of any moving parts.
2. Remove the transaxle dipstick, wipe it clean, reinsert the dipstick as far as it will go, then remove it again.Now check the fluid level on the dipstick. It should be in the "HOT" range on the dipstick. HXG556J

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.
