ENGINE OIL REPLENISHMENT
If the indicated oil level is at or below the lower mark of the dipstick, oilshould be added until the level is at or below the upper mark. To add oil to the engine, remove the filler cap by rotating in an counter- clockwise direction and pour engine oil into the engine. Before checkingthe level again, allow several minutes for the oil to drain into the sump. Replace the oil filler cap rotating it ina clockwise direction until tight.The quantity of oil required to raisethe level from the minimum to maxi- mum level is approximately 1 litre. 1.6L/2.0L
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 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.
2.7L
!WARNING:
Be very careful not to touch the
radiator hose when checking the engine oil as it may be hot enough to burn you.

Coolant recommendations
Only ethylene glycol based coolant with a corrosion inhibitor suited to aluminium alloy engine components should be used in the cooling system.No further additives or inhibitors should be used. The coolant specific gravity should be checked as pre-scribed in the maintenance schedule to ensure adequate frost and corro- sion protection. In addition, the en-gine coolant must be replaced at the specified interval since the corrosion inhibitor properties deteriorate withtime.It is important to note that whilst anincrease in the concentration of anti freeze gives an increase in the level of frost protection, a solution which isin excess of 65% anti freeze will result in reduced frost protection and engine overheating. Therefore therecommended concentration of 50% should not be exceeded for general use. The use of methanol based anti freeze compounds may result in engine over- heating and will invalidate the vehiclewarranty.

ENGINE COOLANT CHECK- ING AND REPLACING
SG050A1-E
WARNING:
Do not remove the radiator cap
when the engine is hot, since the system is pressurized and coolant may be ejected from the radiator resulting in scalding. NOTE: It is imperative that vehicles fitted
with an air conditioning system have a coolant concentration of the recommended strength at all times. The use of the air condition-ing system when the cooling sys- tem is filled with water only will result in the heater matrix freezingand subsequently bursting.

SPARK PLUGS
G060A01GK-EAT Your engine was originally equipped with platinum-tipped or iridium-tipped spark plugs (2.7L only).Platinum-tipped or iridium-tipped sparkplugs will last longer than conven-tional type spark plugs. Platinum- tipped spark plug can be identified by blue lines on the ceramic shell. NOTE: Do not clean or regap platinum- tipped/iridium-tipped spark plugs.
0.039 ~ 0.043 in. (1.0~1.1 mm)
!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.
5. Prepare a suitable quantity of new
engine coolant (refer to section 9) and pour this into the radiator.

0.039 ~ 0.043 in. (1.0~1.1 mm)
6. Start the engine with the radiator
cap still removed and continue to add coolant as the level decreases as air is expelled from the system.When the level remains constant, replace the radiator cap and re- plenish the coolant reservoir.
7. When the engine is hot, check to ensure that no coolant leaks arepresent.

Fluid level should be within "HOT" range

BRAKE SYSTEM CHECKING
CAUTION:
Correct operation of the braking system is essential to the safe operation of the vehicle and there- fore, any maintenance operationsother than those listed below should be entrusted to a Hyundai dealer.
NOTE: Only lint free cloth should be used
for wiping the dipstick. The pres- ence of lint within the transaxle may cause problems with the nor- mal function of the transaxle.
3. If the transaxle fluid level is low, use a funnel to add transaxle fluidthrough the dipstick tube until thelevel reaches the "HOT" range. Do not overfill.
!WARNING:
The electric engine cooling fan automatically switches on and off according to engine temperature. Be careful to keep away from thefan during this check as it may switch on at any time. SG120C2-E Brake Fluid Recommendations Only brake fluid conforming to DOT 3 or DOT 4 specifications or higher may be used in the braking system. Care should be taken to observe theinstructions and precautions printed upon the container.

o If battery electrolyte is spilled onto
skin or into eyes, the effected area must be flushed with copious amounts of water and medical assis-tance sought.
o If battery electrolyte is ingested, copious amounts of water or milkfollowed by an ant-acid (raw egg ormilk of magnesia) must be drunk. Vomiting should not be induced and medical assistance must besought.
o Batteries must only be charged in well venti-lated areas from which naked lights or sources of sparks are excluded.
o Ensure that children, pets or other unautho-rized persons are keptaway from batteries.
o Do not allow anything to bridge the
positive (+) and negative (-) termi-nals of the battery.
o Never invert the battery.
The battery fitted during production isof the "Maintenance Free" type.
ELECTRIC COOLING FANS
!
YG210A1-E
WARNING:
The cooling fan is controlled by engine coolant temperature and may sometimes operate even whenthe engine is not running. Do not touch the radiator fan until it is completely stopped.As the coolant temperature de-creases the fan will automaticallyshut off. This is a normal condi- tion.
Checking Engine Cooling Fan The engine cooling fan should auto- matically come on if the engine cool-ant temperature is high.
Checking Condenser Cooling Fan The condenser cooling fan (in front of the condenser) should come on auto- matically whenever the air conditioneris in operation.
POWER STEERING HOSES
YG220A1-E It is suggested that you check the power steering hose connections for fluid leakage at those intervals speci- fied in the vehicle maintenance sched-ule in Section 5. The power steering hoses should be replaced if there are severe surface cracking, pulling, scuff-ing or worn spots. Deterioration of the hoses could cause premature failure. NOTE: The power steering pump may be noisy when the engine is firststarted in the extreme cold (-4°F). This noise is not abnormal and will stop as the engine warms up.If the power steering pump contin- ues to be noisy after the engine has warmed up, have it inspectedby your Authorized Hyundai Dealer.
