8. Start the engine and check to be sure no oil
is leaking from the drain plug or oil filter.
9. Shut off the engine and recheck the oil level. NOTE: Always dispose of used engine oil in anenvironmentally acceptable manner. It is sug- gested that it be placed in a sealed container and taken to a service station for reclama- tion. Do not pour the oil on the ground or put it into the household trash. WARNING: Used motor oil may cause irritation or can- cer of the skin if left in contact with the skin for prolonged periods of time. Wash your hands thoroughly with soap and warm wa- ter as soon as possible after handling used oil. G050A01A-AAT CHECKING AND CHANGING THE EN- GINE COOLANT 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 is removed. You could be seriously burned if you do not observe this precaution. Do not remove the radiator cap until the radiator is cool to touch.

NOTE: Gasoline Engine Only Before adding the coolant to the radiator, unscrew the flange bolt for fitting water outlet to escape the excess pressure. And if the coolant overflows from the hole while adding the coolant, screw the bolt and con- tinue to add the coolant. 4. Turn the radiator cap counterclockwise with-
out pressing down on it, until it stops. Thisrelieves any pressure remaining in the cool- ing system. And remove the radiator cap by pushing down and turning counterclockwise. Now fill the radiator with clean demineral-ized or distilled water. Continue to add clean demineralized or distilled water in small quan- tities until the fluid level stays up in the radiator neck.
5. Start the engine, top off the radiator with water and then add coolant to the reservoir until the level is between "LOW" and "FULL".
6. Replace the radiator and reservoir caps and check to be sure the drain cocks are fullyclosed and not leaking.
WARNING:The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper- ate even when the engine is not running.
Gasoline Engine only
The coolant level can be seen on the side of the plastic coolant reservoir. The level of the cool- ant should be between the "LOW" and "FULL" lines on the reservoir when the engine is cool. If the level is below the "LOW" mark, add engine coolant to bring it up between "LOW" and "FULL". If the level is low, inspect for coolant leaks and recheck the fluid level fre- quently. If the level drops again, visit your Hyundai dealer for an inspection and diagnosis of the reason.
G050D01HP-GAT To Change the Engine CoolantThe engine coolant should be changed at those intervals specified in the vehicle maintenance schedule in Section 5. CAUTION: Engine coolant can damage the finish of your car. If you spill engine coolant on the car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the park-
ing brake and remove the radiator cap when cool.
2. Be sure your drain receptacle is in place. Open the drain cock on the radiator. Allowall the engine coolant to drain from the cooling system, then securely close the drain cock.

G120A01A-AAT CHECKING THE BRAKESCAUTION: Because brakes are essential to the safe operation of the car, it is suggested that they be checked and inspected by your Hyundai dealer. The brakes should be checked and inspected for wear at those intervals specified in the vehicle mainte- nance schedule in Section 5.
WARNING: The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper- ate even when the 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 en- gine coolant temperature decreases, the fan will automatically shut off. This is a normal condition. G120B02A-AAT Checking the Brake Fluid Level WARNING: Use caution when handling brake fluid. Itcan damage your vision if it gets into your eyes. It will also damage your vehicle’s paint if spilled on it and not removed immediately. G120C02A-AAT Recommended Brake FluidUse only hydraulic brake fluid conforming to DOT 3 or DOT 4 specifications in your braking system. Follow the instructions printed on the container. G120D01A-AAT To Check the Fluid LevelThe fluid level in the brake fluid reservoir should be checked periodically. The level should be between the "MIN" and "MAX" marks on the side of the reservoir. If the level is at or below the "MIN" mark, carefully add fluid to bring it up to "MAX". Do not overfill.
While the engine is idling, apply the brakes and move the gear selector lever from "P" to each of its other positions — "R", "N", "D", "2", "L" — 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 transmission 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.
3. If the transmission fluid level is low, use a funnel to add transmission fluid through thedipstick tube until the level reaches the "HOT" range. Do not overfill.

Any evidence of corro- sion around the battery posts or terminals should be removed using a solution of household bak- ing soda and warm water. After the battery terminals are dry, cover them with a light coat- ing of grease. G220A01A-AAT CHECKING ELECTRIC COOLING FANS WARNING: The cooling fan is controlled by engine cool- ant temperature and may sometimes oper- ate even when the engine is not running. Use extreme caution when working near the blades of the coolant fan, so that you are not injured by a rotating fan blade. As the en- gine coolant temperature decreases the fan will automatically shut off. This is a normal condition.
G210A01A-AAT CHECKING THE BATTERYWARNING: Batteries can be dangerous! When working with batteries, carefully observe the follow- ing precautions to avoid serious injuries. The fluid in the battery contains a strong solu- tion of sulfuric acid, which is poisonous and highly corrosive. Be careful not to spill it on yourself or the car. If you do spill battery fluid on yourself, immediately do the following:
o If battery fluid is on your skin, flush the
affected areas with water for at least 15 minutes and then seek medical assistance.
o If battery fluid is in your eyes, rinse out your eyes with water and get medical assistanceas soon as possible. While you are being driven to get medical assistance, continue to rinse your eyes by using a sponge or soft cloth saturated with water.
o If you swallow battery fluid, drink a large quantity of water or milk followed by milk ofmagnesia, eat a raw egg or drink vegetable oil. Get medical assistance as soon as possible.
While batteries are being charged (either by a battery charger or by the vehicle’s alternator), they produce explosive gases. Always observe these warnings to prevent injuries from occur- ring:

EMISSION CONTROL SYSTEMS 7-1

CONTROL SYSTEMS
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 (For a Gasoline Engine)
(2) Evaporative emission control system (For a Gasoline Engine)
(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 this manual. H010C02Y-GAT 2. Evaporative Emission Control
System; For a Gasoline Engine
The Evaporative Emission Control System is
designed to prevent fuel vapors from escaping into 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 is
running, the fuel vapors absorbed in the canis- ter are drawn into the induction system through the purge control solenoid valve. Purge Control Solenoid Valve The purge control solenoid valve is controlled
by the ECM; when the engine coolant tempera- ture is low, and during idling, it closes, so that evaporated fuel is not taken into the surge tank.
After engine warm-up, during ordinary driving, it opens so as to introduce evaporated fuel to the surge tank. H020A01A-AAT CATALYTIC CONVERTER ; For a Gasoline Engine
H020A01HP
Catalytic Converter
All Hyundai vehicles are equipped with a mono- lith type three-way catalytic converter to re- duce the carbon monoxide, hydrocarbons and nitrogen oxides contained in the exhaust gas. 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 to overheat and create a fire hazard. This risk may be reduced by observing the following:
H010B01A-AAT
1. Crankcase Emission Control System
; For a Gasoline Engine
The Positive Crankcase Ventilation System is employed to prevent air pollution caused by blow-by gases being emitted from the crank- case. This system supplies fresh filtered air to the crankcase through the air intake hose. Inside the crankcase, which the fresh air mixes with blow-by gases, which then pass through the PCV valve into the induction system.7
