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 (Gaso- line Engine/Diesel Engine (2.5 TCI))/ 1.4 liters (Diesel Engine (2.9 CRDi))of oil. 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 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 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 thefinish 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 radiator cap when cool.
G050B01A-DAT Recommended Engine Coolant Use a high quality ethylene-glycol coolant 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.

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 cap by 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 draincock. 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 appropriatequantity 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.

(Gasoline Engine Only)
Your engine was originally equipped
with platinum-tipped spark plugs.
Platinum-tipped spark plugs will last
longer than conventional type spark plugs and can be identified by blue lines on the ceramic shell.
NOTE: Do not clean or regap platinum-
tipped spark plugs.
Unleaded: 1.0 ~ 1.1mm Leaded : 0.7 ~ 0.8mm
Type
RC10PYPB4 (CHAMPION) PFR5N-11 (NGK) RC10YC(CHAMPION)BKR5ES (NGK)
G060B01HP-AAT
Replacing the Spark Plugs
The spark plugs should be changed
at the intervals specified in the ve- hicle maintenance schedule in Sec- tion 5 or whenever engine perfor-mance indicates they should be changed. Symptoms that suggest poor spark plug performance include en-gine misfiring under load, loss of fuel economy, poor acceleration, etc.
When spark plugs are replaced, al-
ways use spark plugs recommended by Hyundai. The use of other sparkplugs can result in loss of perfor- mance, radio interference or engine damage. Recommended Spark Plugs:Remark Unleaded* Leaded
*: Platinum coated
6. Start the engine, top off the radia- tor with water and then add coolant to the reservoir until the level is between "LOW" and "FULL".
7. Replace the radiator and reservoir caps and check to be sure thedrain cocks are fully closed and not leaking.
WARNING:
The cooling fan is controlled byengine coolant temperature and may sometimes operate even when the engine is not running. Useextreme caution when working near the blades of the coolant fan so that you are not injured by a rotat-ing fan blade. As the engine cool- ant temperature decreases, the fan will automatically shut off. This isa normal condition. G060A01L

22CHECKING THE BRAKES
!
G120A01A-AAT
CAUTION:
Because brakes are essential to the safe operation of the car, it issuggested that they be checked and inspected by your Hyundai dealer. The brakes should bechecked and inspected for wear at those intervals specified in the vehicle maintenance schedule inSection 5.!!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 seconds after shutting off engine. High pressure pump, rail, injec- tors and high pressure pipes aresubjected to high pressure even after the engine has been switched off. The fuel jet produced by fuelleaks may cause serious injury, if it contacts with the body. People using pacemakers should notmove closer than 30cm to the ECU or wiring harness within the en- gine room with the engine run-ning, since the high currents in the Common Rail system produce considerable magnetic fields.

24AIR CONDITIONING CARECHECKING THE CLUTCH FLUID
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.
!
G130A01A-AAT
To Check the Clutch Fluid The clutch fluid level in the master cylinder should be checked whenperforming other under hood services. The system should be checked for leakage at the same time. Check tomake certain that the clutch fluid level is always between the "MAX" and "MIN" level markings on the fluid res-ervoir. Fill as required. Fluid loss indi- cates a leak in the clutch system which should be inspected and re-paired immediately. Consult your Hyundai dealer. G130B02A-AAT
To Replace the Fluid
Recommended brake fluid conform-
ing to DOT 3 or DOT 4 specificationshould be used. The reservoir cap must be fully tightened to avoid con-tamination from foreign matter or moisture.
NOTE: Do not allow any other liquids to
contaminate the brake fluid. Seal damage will result.
WARNING:
Use caution when handling brake
fluid. It can damage your vision ifyou get it in your eyes. It will also damage your vehicle’s paint if spilled on it and not removed im-mediately.
