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.

4. When the oil has stopped draining,
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.

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" lineson the reservoir when the engine is cool. If the level is below the "LOW" G050C01L

4. 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.Now fill the radiator with clean dem-ineralized or distilled water. Con- tinue to add clean demineralized or distilled water in small quantitiesuntil the fluid level stays up in the radiator neck. G050D01L
G050D02L
5. Start the engine, top off the radia- tor with water and then add enginecoolant to the reservoir until the level is between "LOW" and "FULL".
6. 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 by
engine coolant temperature andmay sometimes operate even when the engine is not running. Useextreme caution when working near the blades of the cooling fan so that you are not injured by a

SPARK PLUGS
Your engine was originally equipped
with platinum-tipped spark plugs. (If installed)
Platinum-tipped spark plugs will last
longer than conventional type sparkplugs and can be identified by blue lines on the ceramic shell.Unleaded: 1.0 ~ 1.1 mm (0.039 ~ 0.043 in.) Leaded: 0.7 ~ 0.8 mm (0.028 ~ 0.032 in.)

It is always better to check the
transaxle oil level when the engine is cool or cold. If the engine is hot, you should exercise great cautionto avoid burning yourself on hot engine or exhaust parts. G100B01A-AAT
To check the Transaxle Fluid Level
G100B01L
Park the car on level ground with the engine off.
A good quality washer fluid should be used to fill the washer reservoir. The fluid level should be checked morefrequently during inclement weather or whenever the washer system is in more frequent use.The capacity of the washer reservoiris 3.0 liters (3.2 U.S. quarts).
CAUTION:
o Radiator antifreeze (engine cool- ant) should not be used in thewasher system because it willdamage the car's finish.
o The washer should not be oper-
ated if the washer reservoir is empty. This can damage the washer fluid pump.

1. Using a wrench of the correct size,
loosen the oil filler plug by turningit counterclockwise and remove itwith your fingers.
2. Use your finger or suitable tool to
feel inside the hole. The oil level should be at its bottom edge. If it is not, check for leaks before addingoil. To refill the transaxle or bring the oil level up, add oil slowly until it reaches the proper level. Do notoverfill.

You must replace the automatic
transaxle fluid in accordance withintervals specified in the vehicle maintenances schedule in section 5. WARNING:
The transaxle fluid level should bechecked when the engine is at normal operating temperature. This means that the engine, radiator,exhaust system etc., are very hot. Exercise great care not to burn yourself during this procedure.

CHECKING THE BRAKES
CAUTION:
Because brakes are essential to
the safe operation of the car, it is suggested that they be checked and inspected by your Hyundaidealer. The brakes should be checked and inspected for wear at those intervals specified in thevehicle maintenance schedule in Section 5.

Checking the Brake Fluid Level
WARNING:
Use caution when handling brakefluid. It can damage your vision if it gets into your eyes. It will alsodamage your vehicle's paint if spilled on it and not removed im- mediately.
G110D03Y
Fluid level should be within "HOT" range
3. If the transaxle fluid level is low, use a funnel to add transaxle fluid through the dipstick tube until the level reaches the "HOT" range. Do not overfill.
WARNING:
The cooling fan is controlled by
engine coolant temperature andmay sometimes operate even whenthe engine is not running. Use extreme caution when working near the blades of the cooling fan,so that you are not injured by a rotating fan blade. As the engine coolant temperature decreases, thefan will automatically shut off. This is a normal condition.
While the engine is idling, apply the
brakes and move the gear selector lever from "P" to each of its otherpositions -- "R", "N", "D" -- and then return to "N" or "P" with the engine still idling:
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 far as 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. HXG556J
