3 WHAT TO DO IN AN EMERGENCY
4IF THE ENGINE OVERHEATS
D030A02A-AAT If your temperature gauge indicates overheating, you experience a loss of power, or hear loud pinging or knock- ing, the engine is probably too hot. Ifthis happens to you, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Place the gear selector lever in "P"
(automatic) or neutral (manual transaxle) and set the parking brake. If the air conditioning is on, turn it off.
3. If engine coolant is running out un- der the car or steam is coming outfrom the hood, stop the engine. Donot open the hood until the engine coolant has stopped running or the steaming has stopped. If there is novisible loss of engine coolant and no steam, leave the engine running and check to be sure the enginecooling fan is operating. If the fan is not 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 that it is tight. If the drive belt seems to be satisfactory,
3. Attach the clamps of the jumper
cable in the exact location shown.first, attach one clamp of the jumper cable to the positive (+) post or cable of the discharged battery. Thenattach the other end of the same cable to the positive (+) post or cable of the booster battery. Next,using the other cable, attach one clamp to the negative (-) post or cable of the booster battery. Thenattach the other end of that cable to a solid metal part of the engine away from the battery. Do not con-nect the cable to any moving part.
4. Start the engine in the car with the
booster battery and let it run for afew minutes. This will help to as- sure that the booster battery is fully charged. During the jumping opera-tion, run the engine in this vehicle at about 2,000 rpm.
5. Start the engine in the car with the discharged battery using the nor-mal starting procedure. After the engine starts, leave the jumpercables connected and let the engine run at fast idle or about 2,000 rpm for several minutes. 6. Carefully remove the jumper cables
in the reverse order of attachment.
If you do not know why your batterybecame discharged (because the lightswere left on, etc.), have the charging system checked by your Hyundai dealer.

check for coolant leaking from the radiator, hoses or under the car. (Ifthe air conditioning had been in use, it is normal for cold water to be draining from it when you stop).
WARNING:
While the engine is running, keephair, hands, and clothing away from moving parts such as the fan and drive belts to prevent injury. 5. If the water pump drive belt is broken
or coolant is leaking out, stop the engine immediately and call the near- est Hyundai dealer for assistance.
WARNING:
Do not remove the radiator cap when the engine is hot. This can allow coolant to be blown out of the open-ing and cause serious burns.
WARNING (Diesel only):
Never work on injection system withengine running or within 30 sec- onds after shutting off engine. High pressure pump, rail, injectors andhigh pressure pipes are subject to high pressure even after the engine stopped. The fuel jet produced byfuel leaks may cause serious in- jury, if it touch the body. People using pacemakers should not movethan 30cm closer to the ECU or wiring harness within the engine
!
6. If you cannot find the cause of the overheating, wait until the engine temperature has returned to nor-mal. Then, if the engine coolant has been lost, carefully add coolant to the reservoir (page 6-16) to bringthe fluid level in the reservoir up to the halfway mark. CAUTION:
Serious loss of engine coolant indi- cates there is a leak in the coolingsystem and this should be checked as soon as possible by a Hyundai dealer.
room while engine is running, sincethe high currents in the CommonRail system produce considerable magnetic fields.
7. Proceed with caution, keeping alert
for further signs of overheating. If overheating happens again, call a Hyundai dealer for assistance.

EMISSION CONTROL SYSTEMS
3CATALYTIC CONVERTER
H020A01A-GAT
(If installed) ; For a gasoline engine
HXDFL1032
The catalytic converter is part of the
exhaust emission control system. Its purpose is to remove certain engine emission products from the engine'sexhaust. It looks something like a muffler and is located underneath the car in the exhaust system.
Catalytic Converter H020B01A-GAT
About the Catalytic Converter
Exhaust gases passing through the
catalytic converter cause it to operate at very high temperatures. As a re- sult, the introduction of large amountsof unburned gasoline may cause it to overheat and create a fire hazard. This can be avoided by observing thefollowing:
o Use unleaded fuel only.
o Maintain your engine in good con- dition. Extremely high convertertemperatures can result from im-proper operation of the electrical, ignition or fuel injection systems.
o If your engine stalls, pings, knocks, or is hard to start, take your car toyour Hyundai dealer as soon as possible and have the difficultycorrected.
o Avoid driving with a very low fuel
level. If your run out of gasoline, itcould cause the engine 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 the catalytic con- verter to overload.
o Take care not to stop your Hyundai over any combustible material suchas grass, paper, leaves or rags. As these materials could come in con-tact with the catalytic converter and could cause a fire.
o Do not touch the catalytic con- verter or any other part of the ex-haust 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 assis-tance.
H020D01S-GAT
; For a diesel engine
All Hyundai vehicles are equipped
with oxidation type catalytic converter to reduce the carbon monoxide, hy- drocarbons and particulate containedin the exhaust gas.
