CHECKING BRAKE PEDAL CLEARANCE
You need a helper to check the brake pedal clearance. With the engine running, have yourhelper press down on the brake pedal severaltimes and then hold it down with a force of about490N (50 kg, 110 lbs). The brake pedal clear-ance is the distance from the top surface of thebrake pedal to the asphalt sheeting under thefloor mat. If the brake pedal clearance is notwithin the limits specified in the illustration, haveit inspected by your Hyundai dealer and adjust-ed or repaired if necessary.

CAUTION: A burned-out fuse indicates that there is a
problem in the electrical circuit. If you re- place a fuse and it blows as soon as theaccessory is turned on, the problem is seri-ous and should be referred to a Hyundaidealer for diagnosis and repair. Never re-place a fuse with anything except a fusewith the same or a lower amperage rating. Ahigher capacity fuse could cause damageand create a fire hazard.
NOTE: See page 6-23 for the fuse panel descrip-
tions.

CHECKING THE BATTERY
WARNING: 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 andhighly 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 a
battery charger or by the vehicle's alternator),they produce explosive gases. Always observethese warnings to prevent injuries from occur-ring: G210B01A-AAT
Checking the Battery Keep the battery clean. Any evidence of corro-
sion around the battery posts or terminals shouldbe 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 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 theblades of the coolant fan, so that you are notinjured by a rotating fan blade. As the cool-ant temperature decreases the fan will auto-matically shut off. This is a normal condi-tion.
G220B01A-AAT
Checking Engine Cooling Fan The engine coolant fan should come on auto-
matically if the engine coolant temperature ishigh.
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.

tem
The positive crankcase ventilation system is
employed to prevent air pollution caused by 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 (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. H010C01F-GAT
2. Evaporative Emission Control Sys-
tem (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 canister. When the engine is
running, the fuel vapors absorbed in the canis-ter are drawn into the induction system throughthe 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 engine.After engine warm-up, during ordinary driving, itopens so as to introduce evaporated fuel to theengine. H010D01A-AAT
3. Exhaust Emission Control System
The exhaust emission control system is a high-
ly effective system which controls exhaust emis-sions while maintaining good vehicleperformace.

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 largeamounts of unburned gasoline may cause it tooverheat and create a fire hazard. This can beavoided 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 your run out of gasoline, it could cause theengine to misfire and result in excessiveloading 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 thecatalytic converter to overload.
o Take care not to stop your Hyundai over any combustible material such as grass, paper,leaves or rags. As these materials couldcome in contact with the catalytic converterand could cause a fire. o Do not touch the catalytic converter or any
other part of the exhaust system while theengine is running as it is very hot and couldresult in burns.
o Remember that your Hyundai dealer is your best source of assistance.
