POWER STEERING FLUID LEVEL
The power steering fluid level should be checked
regularly.
To check the power steering fluid level, be sure
the ignition is "OFF", then check to make cer- tain that the power steering fluid level is be-tween the "MAX" and "MIN" level markings onthe fluid reservoir.
NOTE: Grinding noise from the power steering
pump may be heard immediately after the engine is started in extremely cold condi-
tions (below -20°C). If the noise stops dur-ing warm up, there is no abnormal functionin the system. This is due to a power steer-ing fluid characteristic in extremely coldconditions.
G230A01X
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 onyourself or the car. If you do spill battery fluid onyourself, 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 beingdriven to get medical assistance, continueto rinse your eyes by using a sponge or softcloth 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 vegetableoil. Get medical assistance as soon aspossible.
While batteries are being charged (either by abattery charger or by the vehicle's alternator),they produce explosive gases. Always observethese warnings to prevent injuries from occur-ring:
o Charge batteries only in a well ventilated area.
o Do not permit flames, sparks or smoking in the area.
o Keep children away from the area. G210B01A-AAT
Checking the Battery
Keep the battery clean. 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 batteryterminals are dry, cover them with a light coat-ing of grease.
G220A01A-AAT
CHECKING ELECTRIC COOLING
FANS
WARNING: The radiator fan is controlled by engine cool- ant temperature and may sometimes operateeven when the engine is not running. Use extreme caution when working near the blades of the cooling fan, so that you are not injuredby a rotating fan blade. As the coolant tem-perature decreases the fan will automaticallyshut off. This is a normal condition.
G220B01A-AAT
Checking Engine Cooling Fan The engine cooling fan should come on auto-
matically if the engine coolant temperature ishigh.
G220C01A-AAT
Checking Condenser Cooling Fan The condenser cooling fan should come on
automatically whenever the air conditioning isin operation.

HEADLIGHT BULB
Replacement instructions:
1. Allow the bulb to cool. Wear eye protection.
2. Always grasp the bulb by its base, avoid touching the glass.
3. Disconnect the connector, then remove the dust cover.
4. Push the bulb spring for removing the head- light bulb.
5. Remove the headlight bulb. If the bulb is burned out, replace it with the same watt- age.
6. Installation is the reverse order of the re- moval.
7. Use the protective cap and carton to promptly dispose of the old bulb.
8. Check for proper headlight aim. WARNING: The halogen bulb contains gas under pres-
sure and if impacted could shatter, and re- sulting in flying fragments. Always wear eye
protection when servicing the bulb. Protectthe bulb against abrasions or scratches andagainst liquids when lighted. Turn the bulbon only when installed in a headlight. Re-place the headlight if damaged or cracked.
Keep the bulb out of the reach of childrenand dispose of the used bulb with care. G290A02X-GAT HEADLIGHT AIMING ADJUSTMENT Before performing aiming adjustment, make sure of the following.
1. Keep all tires inflated to the correct pres- sure.
2. Place the vehicle on level ground and press the front bumper & rear bumper down sev- eral times. Place the vehicle at a distance of3,000 mm (118 in.) from the test wall.
3. See that the vehicle is unloaded (except for full levels of coolant, engine oil and fuel, andspare tire, jack, and tools). Have the driveror equivalent weight placed in driver's seat.
Recommended Fluid
Use PSF-3 type fluid. NOTE: Do not start the engine when the power
steering oil reservoir is empty.
G240A01A-AAT
POWER STEERING HOSES
It is suggested that you check the power steer-
ing hose connections for fluid leakage at those intervals specified in the vehicle maintenanceschedule in Section 5.
The power steering hoses should be replaced if
there is severe surface cracking, pulling, scuff-ing or worn spots. Deterioration of the hosecould cause premature failure.
G260A03A-AAT
REPLACING HEADLIGHT BULBS Before attempting to replace a headlight bulb,
be sure the switch is turned to the "OFF"position.
The next paragraph shows how to reach head-
light bulbs so they may be changed. Be sure toreplace the burned-out bulb with one of thesame number and wattage rating.
CAUTION: Keep the lamps out of contact with petro-
leum product, such as oil, gasoline, etc.

EMISSION CONTROL SYSTEMS 7-1

TROL SYSTEMS
H010A01A-GAT
EMISSION CONTROL SYSTEM (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. the crankcase through the air intake hose.Inside the crankcase, the fresh air mixes withblow-by gases, which then pass through thePCV valve and into the induction system.
H010C02A-GAT
2. Evaporative Emission Control
System (If installed)
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 onboard canister. When the en-gine is running, the fuel vapors absorbed in thecanister are drawn into the induction systemthrough
the purge control solenoid valve.
Purge Control Solenoid Valve The purge control solenoid valve is controlled
by the ECM; when the engine coolant temper-ature is low, and during idling, it closes, so thatevaporated fuel is not taken into the engine.After engine warm-up, during ordinary driving, itopens so as to introduce evaporated fuel to theengine.
H010B01A-AAT
1. Crankcase Emission Control Sys-
tem
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 to H010D01A-AAT
3. Exhaust Emission Control System
The exhaust emission control system is a high-
ly effective system which controls exhaust emis-sion while maintaining good vehicle perfor-mance.
H020A01A-GAT
CATALYTIC CONVERTER (If Installed)
The catalytic converter is part of the exhaust
emission control system. It's purpose is to re-move certain engine emission products from
the engine's exhaust. It looks something like amuffler and is located underneath the car in theexhaust system. Catalytic Converter

EMISSION CONTROL SYSTEMS
7-2 o Do not touch the catalytic converter or any
other part of the exhaust system while the engine is running as it is very hot and couldresult in burns.
o Remember that your Hyundai dealer is your best source of assistance.
H020B01A-GAT
About the Catalytic Converter
Exhaust gases passing through the catalytic
converter cause it to operate at very high tem-peratures. As a result, the introduction of large
amounts of unburned gasoline may cause it to
overheat and create a fire hazard.
This can be avoided by observing the following:
o Use unleaded fuel only.
o Maintain your engine in good condition. Ex- tremely high converter temperatures can result from improper operation of the electri-cal, ignition or fuel injection systems.
o If your engine stalls, pings, knocks, or is hard to start, take your car to your Hyundaidealer as soon as possible and have thedifficulty corrected.
o Avoid driving with a very low fuel level. If you run out of gasoline, it could cause the engineto misfire and result in excessive loading of
the catalytic converter.
o Avoid idling the engine for periods longer than 10 minutes.
o Your Hyundai should not be either pushed or pulled to get it started.This can cause the catalytic converter tooverload.
o Take care not to stop your Hyundai over any combustible material such as grass, paper,leaves or rags. As these materials could
come in contact with the catalytic converterand could cause a fire.
