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"
(auto-matic), 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 (Diesel only):
Never work on injection system with engine running or within 30 sec- onds after shutting off engine. Highpressure pump, rail, injectors and high pressure pipes are subject to high pressure even after the enginestopped. The fuel jet produced by fuel leaks may cause serious in- jury, if it touch the body. Peopleusing pacemakers should not move than 30cm closer to the ECU or wiring harness within the engine 5. If the water pump drive belt is bro-
ken or coolant is leaking out, stopthe engine immediately and call the nearest Hyundai dealer for assis- tance. CAUTION:
Serious loss of engine coolant indi- cates there is a leak in the cooling system and this should be checkedas soon as possible by a Hyundai dealer.
room while engine is running, since the high currents in the CommonRail system produce considerable magnetic fields.
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 hasbeen lost, carefully add coolant to the reservoir (page 6-14) to bring the fluid level in the reservoir up tothe halfway mark.
WARNING:
While the engine is running, keephair, hands, and clothing away from moving parts such as the fan and drive belts to prevent injury.
WARNING:
Do not remove the radiator cap whenthe engine is hot. This can allowcoolant to be blown out of the open- ing and cause serious burns. 7. Proceed with caution, keeping alert
for further signs of overheating. If overheating happens again, call a Hyundai dealer for assistance.

The vapor hose and fuel filler cap should be inspected at those intervals specified in the maintenance sched-ule. Make sure that a new vapor hose or fuel filler cap is correctly replaced. F060F01A-AAT
o Vacuum, Crankcase
Ventilation Hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical dam-age. Hard and brittle rubber, cracking, tears, cuts, abrasions, and excessiveswelling indicate deterioration. Particu- lar attention should be paid to examin- ing those hose surfaces nearest tohigh heat sources, such as the ex- haust manifold.
Inspect the hose routing to assure that
the hoses do not come in contact withany heat source, sharp edges or mov- ing component which might cause heatdamage or mechanical wear. Inspect all hose connections, such as clamps and couplings, to make sure they aresecure, and that no leaks are present. Hoses should be replaced immedi- ately if there is any evidence of dete-rioration or damage. F060N02E-GAT

ENGINE OIL CONSUMPTION Function of Engine Oil
Engine oil has the primary function of
lubricating and cooling the inside of the engine. Engine oil consumption
It is normal that an engine should
consume some engine oil while nor- mal driving. The cause of oil con- sumption in a normal engine are asfollows;
o Engine oil is used to lubricate pis- tons, piston rings and cylinders. A thin film of oil is left on the cylinder wall when a piston moves downwards in the cylinder. High negative pressure generated dur-ing engine operation sucks some of the oil into the combustion cham- ber.This oil with some oil of the cylin-der wall is burned by the high tem-perature combustion gases during the combustion process. o The engine oil consumption is
strongly effected by the viscosity and quality of oil, engine rpm and driving condition etc. The engine oil is more consumed under severedriving conditions such as high speeds and frequent acceleration and deceleration than normal driv-ing condition.
1. Remove the oil filler cap by turning
it counter-clockwise.
2. Add oil, then check the level again. Do not overfill.
3. Replace the cap by turning it clock- wise.
The distance between the "F" and "L"marks is equal to about 1 liter(GasolineEngine)/1.2 liter(Diesel Engine) of oil.

The engine coolant should be com- patible with aluminum engine parts.Additional corrosion inhibitors or addi- tives should not be used. The cooling system must be maintained with thecorrect concentration and type of en- gine coolant to prevent freezing and corrosion. Never allow the concentra-tion of antifreeze to exceed the 60% level or go below the 35% level, or damage to the cooling system mayresult. For proper concentration when adding or replacing the engine cool- ant, refer to the following table. G050C01A-GAT
To Check the Coolant Level The level of the coolant should bebetween the "L" and "F" lines on thereservoir when the engine is cold. If the level is below the "L" mark, add engine coolant to bring it up between"L" and "F". If the level is low, inspect for coolant leaks and recheck the fluid level frequently. If the level dropsagain, visit your Hyundai dealer for an inspection and diagnosis of the rea- son.

4. Turn the radiator cap counterclock-
wise without pressing down on it, until it stops. This relieves any pres- sure remaining in the cooling sys-tem. And remove the radiator cap by pushing down and turning coun- terclockwise.Fill the radiator with clean deminer-alized or distilled water. Continueto add clean demineralized or dis- tilled water in small quantities until the fluid level stays up in the radia-tor neck. G050D01FC

5. Start the engine, top off the radia- tor with water and then add engine coolant to the reservoir until the level is between "L" and "F".
6. Replace the radiator and reservoir caps and check to be sure thedrain cocks are fully closed and not leaking.
G050D02A-AAT
To Change the Coolant
The coolant should be changed at
those intervals specified in the ve-hicle maintenance schedule in Sec- tion 5.
! CAUTION:
Engine coolant can damage the
finish of your car. If you spill en- gine 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 theradiator. Allow all the engine cool- ant to drain from the cooling sys- tem, then securely close the draincock.
3. Check Section 9 for the capacity of the cooling system in your car.Then, following the manufacturer's directions on the engine coolant container, add the appropriatequantity of coolant to the radiator.
