WARNING:
Never remove the radiator cap when the engine is hot. The engine cool- ant is under pressure and coulderupt and cause severe burns. Wait until the engine is cool before re- moving the radiator cap. The needle on the engine coolant tem-perature gauge should stay in themiddle between "H" and "C". If it moves across the dial to "H" (Hot), pull over and stop as soon as possible and turnoff the engine. Then open the hood and after the engine has cooled, check the coolant level and the water pumpdrive belt. If you suspect cooling sys- tem trouble, have your cooling system checked by a Hyundai dealer as soonas possible.

!
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.
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.
!
! CAUTION:
Slowly pour the recommended oil using by a funnel. Do not overfill not to damage engine.
WARNING:
Be very careful not to touch the radiator hose when adding the en- gine oil as it may be hot enough to burn you.

CHECKING AND CHANGING THE ENGINE COOLANT
G050A01A-AAT
WARNING:
Do not remove the radiator cap
when the engine is hot. When the engine is hot, the engine coolant is under pressure and may eruptthrough the opening if the cap is removed. You could be seriously burned if you do not observe thisprecaution. Do not remove the radiator cap until the radiator is cool to the touch.
10. Start the engine and check to be
sure no oil is leaking from thedrain plug or oil filter.
11.Shut off the engine and recheck
the oil level.
NOTE:
o It is recommended that the en- gine oil and filter should be changed by an authorized Hyundai dealer.
o Always dispose of used engine oil in an environmentally accept-able manner. It is suggested that it be placed in a sealed container and taken to a service station formaybe reclaimation. Do not pour the oil on the ground or put it into the household trash.
WARNING:
Used motor oil may cause irrita- tion or cancer of the skin if left in contact with the skin for prolongedperiods of time. Wash your hands thoroughly with soap and warm water as soon as possible afterhandling used oil.
8. After mounting a new centerpipe O-
ring, new oil filter element and newO-ring to upper cap, install the up- per cap to oil filter housing and retighten by turning it clockwise.Do not over-tighten. Tightening torque : 2.5 kgf.m
CAUTION:
Don't use old oil filter upper cap O-ring and centerpipe O-ring
9. Refill the crankcase with the rec- ommended engine oil. Refer to the specification in chapter 9 for engine oil capacity.
CAUTION:
Slowly pour the recommended oilby into a funnel. Do not overfill not to damage the engine.

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 parking brake and remove the radia- tor 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.
!
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.
WARNING:
Remove the radiator cap when theradiator is cool.
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.

5. Start the engine, top off the radiator 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 the draincocks are fully closed and not leak- ing.
!WARNING:
The cooling fan is controlled by
engine coolant temperature and may sometimes operate even when theengine is not running. Use extreme caution when working near the blades of the cooling fan so thatyou are not injured by a rotating fan blade. As the engine coolant tem- perature decreases, the fan will au-tomatically shut off. This is a nor- mal condition.
