EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
F060M01A-AAT
o Engine Oil and Filter
The engine oil and filter should be changed at the intervals specified in the maintenance schedule. If the car is being driven in severe conditions,more frequent oil and filter changes are required. F060B01A-AAT
o Drive Belts
Inspect all drive belts for evidence of cuts, cracks, excessive wear or oil and replace if necessary. Drive beltsshould be checked periodically for proper tension and adjusted as nec- essary. After installing a new filter, run the
engine for several minutes, and checkfor leaks at the connections. Fuelfilters should be installed by trained technicians.
F060D01A-AAT
o Fuel Lines, Fuel Hoses and Connections
Check the fuel lines, fuel hoses and connections for leakage and damage.Have a trained technician replace any damaged or leaking parts immedi- ately. F060E01A-AAT
o Timing Belt Inspect all parts related to the timing belt for damage and deformation. Replace any damaged parts immedi- ately. F060G01A-AAT
o Vapor Hose and Fuel Filler Cap The vapor hose and fuel filler cap should be inspected at those inter- vals specified in the maintenance schedule. Make sure that a new va-por hose or fuel filler cap is correctly replaced. F060F01A-AAT
o Vacuum, Crankcase Ventila-
tion Hoses
Inspect the surface of hoses for evi- dence of heat and/or mechanical dam-age. Hard and brittle rubber, crack- ing, tears, cuts, abrasions, and ex- cessive swelling indicate deteriora-tion. Particular attention should be paid to examine those hose surfaces nearest to high heat sources, such asthe exhaust manifold.Inspect the hose routing to assurethat the hoses do not come in contact with any heat source, sharp edges or moving component which might causeheat damage or mechanical wear. Inspect all hose connections, such as clamps and couplings, to make surethey are secure, and that no leaks are present. Hoses should be replaced immediately if there is any evidenceof deterioration or damage.
F060C01A-AAT
o Fuel Filter
A clogged filter can limit the speed atwhich the vehicle may be driven, dam- age the emission system and cause hard starting. If an excessive amountof foreign matter accumulates in the fuel tank, the filter may require re- placement more frequently.

G030A01A-AAT CHECKING THE ENGINE OIL 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 useand more often if you are on a trip or driving in severe conditions. G030B01A-GAT Recommended Oil
G030B01L
SH, SG or SG/CD (API) multi-grade and fuel efficient oil is recommended. NOTE: SAE 5W-20 is not recommended for sustained high speed vehicle operation.G030C02A-AAT
To Check the Oil Level
Before checking the oil, warm up the
engine to the normal operating tem- perature and be sure your car is parked on level ground. Turn the en-gine off.
Wait five minutes, then remove the
dipstick, wipe it off, fully reinsert thedipstick and withdraw it again. Thennote the highest level the oil has reached on the dipstick. It should be between the upper ("FULL") and lower("LOW") range. HXG094J
G030D01A-GAT
Adding 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 of oil.

replace the drain plug using a new washer and retighten by turning itclockwise. Oil pan drain plug tightening torque : 3.5 ~4.0 kgf.m
5. Remove the oil filter by turning it counterclockwise with a oil filter wrench of the proper size. A cer- tain amount of oil will come out when you remove the filter. So besure to have your drain pan in place underneath it.
6. Install a new oil filter in accordance with the instructions on the carton or on the filter itself. Do not over-tighten. Oil filter tightening torque : 1.2 ~ 1.6 kgf.m Be sure that the mounting surface on the engine is clean and that theold gasket is removed completely. Lubricate the new gasket on the filter with clean engine oil beforeinstallation. 7. Refill the crankcase with the rec-
ommended engine oil. Refer to thespecification in chapter 9 for en-gine oil capacity.
8. Start the engine and check to be sure no oil is leaking from the drain plug or oil filter.
9. Shut off the engine and recheck the oil level.
NOTE: Always dispose of used engine oil
in an environmentally acceptable manner. It is suggested that it beplaced in a sealed container and taken to a service station for recla- mation. Do not pour the oil on theground or put it in with the house- hold 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. G050A01A-AAT
CHECKING AND CHANGING THE ENGINE COOLANT
WARNING:
Do not remove the radiator cap
when the engine is hot. When the engine is hot, the engine coolantis under pressure and may erupt through the opening if the cap is removed. You could be seriouslyburned if you do not observe this precaution. Do not remove the ra- diator cap until the radiator is coolto the touch.

G050D02A-AAT 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.
2. Be sure your drain receptacle is in place. Open the drain cock on theradiator. Allow all the engine coolant to drain from the cooling system,then securely close the drain cock.
Use a high quality ethylene-glycol
coolant in a 50/50 mix with water. The engine coolant should be compatible with aluminum engine parts. Addi-tional corrosion inhibitors or additives should not be used. The cooling sys- tem must be maintained with the cor-rect concentration and type of engine coolant to prevent freezing and corro- sion.
Never allow the concentration of an-
tifreeze to exceed the 60% level or gobelow the 35% level or damage to thecoolant system may result. For proper concentration when adding or replac- ing the engine coolant, refer to thefollowing table.
