!
G020D01TG-GAT Improper or incomplete service may result in problems. This section gives instructions only for the maintenance items 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. Youcan 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 an autho-rized 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 result in injury. Therefore, if you mustrun the engine while working un- der the hood, make certain that you remove all jewelry (especiallyrings, bracelets, watches, and necklaces) and all neckties, scarves, and similar loose cloth-ing before getting near the engine or cooling fans.
CHECKING THE ENGINE OIL
G030A02O-GAT Recommended Oil Gasoline Engine
Engine oil is essential to the perfor- mance and service of the engine. It is suggested that you check the oil level at least once a week in normal use andmore often if you are on a trip or driving in severe conditions. The engine oil quality should meet the following classification. API SJ, SL or ABOVE, ILSAC GF-3 or ABOVE G030B01JM

G350A01A-GAT ENGINE OIL CONSUMPTION Function of Engine Oil Engine oil has the primary function of lubricating and cooling the inside of theengine. Engine oil consumption It is normal that an engine should consume some engine oil while nor-
mal driving. The cause of oil consump- tion 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 the cylinder wall when a piston moves down- wards in the cylinder. High negativepressure generated during engine operation sucks some of the oil into the combustion chamber.This oil with some oil of the cylinder wall is burned by the high tempera- ture combustion gases during thecombustion process.
NOTE:
o It is recommended that the engine
oil and filter should be changed by an authorized Hyundai dealer.
o Always dispose of used engine oil in an environmentally acceptablemanner. It is suggested that it beplaced in a sealed container and taken to a service station for maybe reclaimation. Do not pour the oilon the ground or put it into the household trash.
!WARNING:
Used motor oil may cause irritation or cancer of the skin if left in contact with the skin for prolonged periodsof time. Wash your hands thoroughly with soap and warm water as soon as possible after handling used oil.
!
If the oil level is close to or below the "L" mark, add oil until it reaches the "F"mark. To add oil:
1. Remove the oil filler cap by turning it counterclockwise.
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(Gasoline Engine)/1.5 liter(Diesel Engine) of oil.
WARNING:
Be very careful not to touch the radia-tor hose when adding the engine oilas it may be hot enough to burn you. CAUTION:
Slowly pour the recommended oilby using a funnel. Do not overfill soas not to damage engine.

G050B01A-AAT 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. Additional corrosion inhibitors or additives shouldnot be used. The cooling system must be maintained with the correct con- centration and type of engine coolantto prevent freezing and corrosion. Never allow the concentration of anti- freeze to exceed the 60% level or gobelow the 35% level, or damage to the cooling system may result. For proper concentration when adding or replacingthe engine coolant, refer to the following table.

CHECKING AND CHANGING THE ENGINE COOLANT
G050A01TG-AAT
WARNING:
Do not remove the radiator cap when the engine is hot. When the engine ishot, the engine coolant is under pres- sure and may erupt through the open- ing if the cap is removed. You couldbe seriously burned if you do not observe this precaution. Do not re- move the radiator cap until the radia-tor is cool to the touch. NOTE: It is recommended that the engine coolant should be changed by an authorized Hyundai dealer.
o The engine oil consumption is strongly
effected by the viscosity and qualityof oil, engine rpm and driving condi- tion etc. The engine oil is more con- sumed under severe driving condi-tions such as high speeds and fre- quent acceleration and deceleration than normal driving condition.

G050C01TG-GAT To Check the Coolant Level Gasoline Engine The coolant level can be seen on the side of the plastic coolant reservoir.
OMC055007
OMC055008
Diesel Engine The level of the coolant should be between 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 drops again,visit your Hyundai dealer for an inspec- tion and diagnosis of the reason.
!WARNING:
The cooling fan is controlled by en- gine coolant temperature and may sometimes operate even when theengine is not running. Use extreme caution when working near the blades of the coolant fan so that youare not injured by a rotating fan blade. As the engine coolant tem- perature decreases, the fan will auto-matically shut off. This is a normal condition.
! CAUTION:
o 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.
o The engine in your vehicle has
aluminum engine parts and mustbe protected by an ethylene-gly- col base coolant to prevent corro-sion and freezing. And, do not use the hard water. The hard water can cause enginedamage from corrosion, overheat- ing or freezing.

3. If the transaxle fluid level is low, use
a funnel to add transaxle fluid through the dipstick tube until the levelreaches the "HOT" range. Do not overfill.
WARNING:
The cooling fan is controlled by en- gine coolant temperature and maysometimes operate even when the engine is not running. Use extreme caution when working near the bladesof the cooling fan, so that you are not injured by a rotating fan blade. As the engine coolant temperature decreas-es, the fan will automatically shut off. This is a normal condition. WARNING (
Diesel only):
Never work on injection system with engine running or within 30 seconds after shutting off engine. High pres- sure pump, rail, injectors and highpressure pipes are subjected to high pressure even after the engine has been switched off. The fuel jet pro-duced by fuel leaks may cause seri- ous injury, if it contacts with the body. People using pacemakersshould not move closer than 30cm to the ECU or wiring harness within the engine room with the engine run-ning, since the high currents in the Common Rail system produce con- siderable magnetic fields.
G110D03MC
Fluid level should be within "HOT" range
1. Open the hood, being careful to keep
hands, long hair and clothing clear of any moving parts.
2. Remove the transaxle dipstick, wipe it clean, reinsert the dipstick as faras it will go, then remove it again.Now check the fluid level on the dipstick. It should be in the "HOT" range on the dipstick. G110D02MC

G140B01A-AAT Checking the Air Conditioning Operation
1. Start the engine and let it run at afast idle for several minutes with the air conditioning set at the maximum cold setting.
2. If the air coming out of the in-dash vents is not cold, have the air condi-tioning system inspected by yourHyundai dealer.
G140C01A-AAT Lubrication To lubricate the compressor and the seals in the system, the air conditioning should be run for at least 10 minuteseach week. This is particularly important during cool weather when the air condi- tioning system is not otherwise in use.
! CAUTION:
Running the air conditioning sys- tem for extended periods of time with a low refrigerant level may damage the compressor.
AIR CONDITIONING CARE
G140A01A-AAT Keeping the Condenser Clean The air conditioning condenser (and engine radiator) should be checkedperiodically for accumulation of dirt, dead insects, leaves, etc. These can interfere with maximum cooling effi-ciency. When removing such accumu- lations, brush or hose them away care- fully to avoid bending the cooling fans.CHECKING THE CLUTCH FLUID
G130A01A-AAT (If Installed) To Check the Clutch Fluid The clutch fluid level in the master cylinder should be checked when per- forming other under hood services. Thesystem should be checked for leakage at the same time. Check to make certain that the clutchfluid level is between the "MAX" and "MIN" level markings on the fluid reser- voir. Fill as required. Fluid loss indi-cates a leak in the clutch system which should be inspected and repaired im- mediately. Consult your Hyundai dealer.
