WHAT TO DO IN AN EMERGENCY
3-2 3. If coolant is running out under the car or
steam is coming out from under the bonnet stop the engine. Do not open the bonnetuntil the coolant has stopped running or thesteaming has stopped. If there is no visibleloss of coolant and no steam, leave theengine running and check to be sure theengine cooling fan is operating. If the fan isnot running, turn the engine off.
4. Check to see if the water pump drive belt is missing. If it is not missing, check to see thatit is tight. If the drive belt seems to besatisfactory, check for coolant leaking fromthe radiator, hoses or under the car. (If theair conditioner had been in use, it is normalfor cold water to be draining from it).
WARNING: While the engine is running, keep hands andclothing away from moving parts such asthe fan and drive belts to prevent injury.
5. If the water pump drive belt is broken or coolant is leaking out, stop the engine imme-diately and call the nearest Hyundai dealerfor assistance.
WARNING: Do not remove the radiator cap when theengine is hot since steam and boiling watermay be ejected from the radiator resulting inburns or scalding.
CAUTION:
Personal injury and damage to the vehicle
may occur if jump starting is not performedcorrectly. If any doubt exists as to how thisoperation should be performed, seek assis-tance from qualified personnel. WARNING:
Motor vehicle batteries contain sulphuric
acid and emit hydrogen gas. Protective cloth- ing should be worn and care exercised toprevent the acid from coming into contactwith skin or clothing and the vehicle. Nakedlights should not be permitted in the vicinityof the battery. Care should be exercised topreventsparks occurring during connection.If acid accidentally comes into contact withskin or eyes, the affected area should imme-diately be flushed with copious amounts ofwater and medical assistance sought.
1. Ensure that the booster battery is 12 volt type. If the booster battery is installed in another vehicle, ensure that the two vehi-cles are not touching.
2. Turn off all unnecessary electrical equip- ment in both vehicles.
3. Ensure that the engine of the vehicle provid- ing the jump start is running prior to connec-tion of the jump cables.
4. Connect the red jump cable to the positive (+) terminal of the booster battery and theother end to the positive (+) terminal of thedischarged battery. 5. Attach the black jump cable to the negative
(-) terminal of the booster battery, and theother end to a ground point within the enginecompartment of the vehicle with the flat bat-tery. Do not connect to the negative batteryterminal of the flat battery since sparks maybe generated with the subsequent risk ofexplosion.
6. Raise the booster vehicle engine speed to 2,000 r.p.m. and start the engine of thevehicle with the flat battery.
7. Remove jump cables in the reverse order of installation (black cable first).
NOTE: If the jump cable is incorrectly installed, damage to the vehicle electrical system mayoccur, in particular the electronic compo-nents such as the Fuel Injection systemcomputer and the Automatic Transaxle com-puter. The battery must never be discon-nected whilst the engine is running. XD040A1-E
IF THE ENGINE OVERHEATS If the temperature gauge indicates overheating:
1. Pull off the road and stop as soon as it is safe to do so.
2. Place the gear selector lever in "P" (auto- matic), or neutral (manual transaxle, semi- automatic transalxe) and set the parkingbrake. If the air conditioner is on, turn it off.

EMISSION CONTROL SYSTEMS 7-1
H010A01A-GAT EMISSION CONTROL SYSTEM (Not all models) 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. ZH000A1-A
7. EMISSION
CONTROL SYSTEMS
H010B01A-AAT
1. Crankcase Emission Control Sys-
tem
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, the fresh air mixes with
blow-by gases, which then pass through thePCV valve and into the induction system.
H010D01A-AAT
3. Exhaust Emission Control SystemThe Exhaust Emission Control System is a
highly effective system which controls exhaust
emission while maintaining good vehicle perfor-mance.
H010C02A-GAT
2. Evaporative Emission
Control System (Not all models)
The Evaporative Emission Control System is
designed to prevent fuel vapors from escapinginto the atmosphere.
Canister While the engine is inoperative, fuel vapours
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 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.
H020A01ACatalytic Converter
H020A01A-GAT CATALYTIC CONVERTER (Not all models) The catalytic converter is part of the exhaust
emission control system. Its 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.

7-2EMISSION CONTROL SYSTEMS
H020B01A-GAT About the Catalytic ConverterExhaust 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 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 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 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 could
come 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.
