6CHECKING THE ENGINE OIL
G030A01A-AAT Engine oil is essential to the perfor-
mance and service of the engine. It is suggested that you check the oil levelat least once a week in normal use and more often if you are on a trip or driving in severe conditions.MAINTENANCE PRECAU- TIONS
!
G020D01TG-GAT Improper or incomplete service may
result in problems. This section gives instructions only for the maintenanceitems that are easy to perform.
Several procedures should be done by
an authorized Hyundai dealer.
NOTE: Improper owner maintenance dur-
ing the warranty period may affect warranty coverage. WARNING:
o Performing maintenance work on a vehicle can be dangerous. You can be seriously injured while performing some maintenance procedures. If you lack sufficientknowledge and experience or the proper tools and equipment to do the work, have it done by anauthorized Hyundai dealer.
o Working under the hood with the engine running is dangerous. It becomes even more dangerous when you wear jewelry or looseclothing. These can become en- tangled in moving parts and re- sult in injury. Therefore, if youmust run the engine while work- ing under the hood, make certain that you remove all jewelry (espe-cially rings, bracelets, watches, and necklaces) and all neckties, scarves, and similar loose cloth-ing before getting near the en- gine or cooling fans.

10CHECKING 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 underpressure and may erupt through the opening if the cap is removed. You could be seriously burned if you donot observe this precaution. Do not remove the radiator cap until the radiator is cool to touch.
G350A01A-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 as follows;
o Engine oil is used to lubricate pis-
tons, piston rings and cylinders. A thin film of oil is left on thecylinder wall when a piston movesdownwards in the cylinder. High negative pressure generated dur- ing engine operation sucks someof 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 duringthe combustion process.
o The engine oil consumption is strongly effected by the viscosityand 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.
!
! CAUTION:
Slowly pour the recommended oil using by a funnel. Do not overfillnot 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 toburn you.

To Check the Coolant Level
The coolant level can be seen on the
side of the plastic coolant reservoir. The level of the coolant should be between the "LOW" and "FULL" lines on the reservoir when the engine iscool. If the level is below the "LOW" mark, add engine coolant to bring it up between "LOW" and "FULL". If thelevel is low, inspect for coolant leaks and recheck the fluid level frequently. If the level drops again, visit yourHyundai dealer for an inspection and diagnosis of the reason. G050D02HP-GAT
To Change the Engine Coolant
The engine coolant should be changed at those intervals specified in the ve- hicle maintenance schedule in Sec- tion 5.
CAUTION:
Engine coolant can damage the fin-ish of your car. If you spill enginecoolant on the car, wash it off thor- oughly with clean water.
1. Park the car on level ground, set the parking brake and remove the radia- tor cap when cool.
G050B01A-DAT
Recommended Engine Coolant
Use a high quality ethylene-glycol cool-ant in a 50/50 mix with water. Theengine coolant should be compatible with aluminum engine parts. Addi- tional corrosion inhibitors or additivesshould not be used. The cooling sys- tem must be maintained with the cor- rect concentration and type of enginecoolant to prevent freezing and corro- sion. Never allow the concentration of antifreeze to exceed the 60% level orgo below the 35% level, otherwise damage to the cooling system may result. For proper concentration whenadding or replacing the engine cool- ant, refer to the following table. HHP5005

NOTE: Gasoline Engine Only Before adding the coolant to the radiator, unscrew the bolts on theengine cover, remove the engine cover and unscrew the flange bolt for fitting water outlet to escapethe excess pressure. And if the coolant overflows from the hole while adding the coolant, screwthe bolt and continue to add the coolant.
G050D01HP 2. 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 capby pushing down and turning coun- terclockwise.
3. 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 drain cock. HHP5006

4. 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 appropriate quan-tity of coolant to the radiator.
5. 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.

13CHANGING THE AIR CLEANER FILTER
!
6. Start the engine, top off the radiator
with water and then add coolant to the reservoir until the level is be- tween "LOW" and "FULL".
7. 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 byengine coolant temperature and may sometimes operate even when the engine is not running. Use extremecaution when working near the blades of the coolant fan so that you are not injured by a rotating fanblade. As the engine coolant tem- perature decreases, the fan will au- tomatically shut off. This is a nor-mal condition. G070A03Y-AAT The replacement of air cleaner filter is
performed in the following manner.
1. Unsnap the clips around the cover.
2. When this is done, the cover can be lifted off, the old filter removed and the new filter put in its place.
Genuine Hyundai replacement parts
are recommended. HHP5013
!
CAUTION:
o Operating your vehicle without a proper air cleaner filter in place can result in excessive engine wear.
o When removing the air cleaner filter, be careful that dust or dirtdoes not enter the air intake. These may result in damage to the air cleaner filter.

Fluid level should be within "HOT" range
3. If the transmission fluid level is low, use a funnel to add transmission fluid through the dipstick tube until the level reaches the "HOT" range. Do not overfill. G110D04HP
!!WARNING:
The cooling fan is controlled by
engine coolant temperature and may sometimes operate even whenthe engine is not running. Use extreme caution when working near the blades of the cooling fan, sothat you are not injured by a rotat- ing fan blade. As the engine cool- ant temperature decreases, the fanwill automatically shut off. This is a normal condition. WARNING (Diesel only):
Never work on injection system with
engine running or within 30 sec- onds after shutting off engine. High pressure pump, rail, injectors and high pressure pipes are subjectedto high pressure even after the en- gine has been switched off. The fuel jet produced by fuel leaks may causeserious injury, if it contacts with the body. People using pacemakers should not move closer than 30cmto the ECU or wiring harness within the engine room with the engine running, since the high currents inthe Common Rail system produce considerable magnetic fields.

Checking the Air Conditioning Operation
1. Start the engine and let it run at
fast idle for several minutes with the air conditioning set at the maxi- mum cold setting.
2. If the air coming out of the in-dash vents is not cold, have the air con-ditioning system inspected by yourHyundai dealer.
CAUTION:
Running the air conditioning sys-
tem for extended periods of timewith a low refrigerant level may damage the compressor.
! G140C01A-AAT
Lubrication
To lubricate the compressor and the
seals in the system, the air condition- ing should be run for at least 10 minutes each week. This is particu-larly important during cool weather when the air conditioning system is not otherwise in use.
AIR CONDITIONING CARE
G140A01A-AAT Keeping the Condenser Clean The air conditioning condenser (and engine radiator) should be checked periodically for accumulation of dirt, dead insects, leaves, etc. These caninterfere with maximum cooling effi- ciency. When removing such accu- mulations, brush or hose them awaycarefully to avoid bending the cooling fans.
