CHANGING THE OIL AND FILTER
Oil filler cap
Oil filter G040A01X
Drain plug
The engine oil and filter should be changed at
those intervals specified in the maintenance schedule in Section 5. If the car is being driven in severe conditions, more frequent oil and filter
changes are required.
The procedure for changing the oil and filter is
as follows:
1. Park the car on level ground and set the parking brake. Start the engine and let it warm up until the needle on the coolanttemperature gauge moves above the lowest
mark. Turn the engine off and place the gearselector lever in "P" (automatic transaxle) orreverse gear (manual transaxle, semi-auto-matic transaxle).
2. Open the hood and remove the engine oil filler cap. 3. Slide underneath the car and loosen the
drain plug by turning it counterclockwisewith a wrench of the proper size. Be sure
that a drain pan is in position to catch the oilas it drains out, then remove the drain plug.
WARNING: Be very careful when draining the engine oil
as it may be hot enough to burn you!
4. When the oil has stopped draining, replace the drain plug using a new washer and retighten by turning it clockwise.

CHECKING AND CHANGING THE EN- GINE COOLANT
WARNING: Do not remove the radiator cap when the en-
gine is hot. When the engine is hot, the coolant is under pressure and may erupt through theopening if the cap is removed. You could beseriously burned if you do not observe thisprecaution. Do not remove the cap until theradiator is cool to the touch.

Recommended Coolant
G050B01A
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The coolant should be compatible with aluminum engine parts. Addi-tional corrosion inhibitors or additives shouldnot be used. The cooling system must be main-tained with the correct concentration and typeof coolant to prevent freezing and corrosion.
NEVER allow the concentration of antifreeze to
exceed the 60% level or go below the 35% levelor damage to the coolant system may result.For proper concentration when adding or re-placing the coolant, refer to the following table.
Coolant concentration
ZG050C1-A
To Check the Coolant Level
G050C01A
The coolant level can be seen on the side of the
plastic coolant reservoir. The level of the cool- ant should be between the "LOW" and "FULL"lines on the reservoir. If the level is below the"LOW" mark, add coolant to bring it up between"LOW" and "FULL". If the level is low, inspectfor coolant leaks and recheck the fluid levelfrequently. If the level drops again, visit yourHyundai dealer for an inspection and diagnosisof the reason. ZG050D2-A
To Change the Coolant
The coolant should be changed at those inter-vals specified in the vehicle maintenance sched-ule in Section 5. NOTE: Coolant can damage the finish of your car. If you spill coolant on the car, wash it offthoroughly with clear water.
1. Park the car on level ground, set the parking brake and remove the radiator cap whencool.
2. Be sure your drain receptacle is in place. Open the drain cock on the radiator. Allowall the coolant to drain from the coolingsystem, then securely close the drain cock.
3. Check Section 9 for the capacity of the cooling system in your car. Then, followingthe manufacturer’s directions on the coolantcontainer, add the appropriate quantity ofcoolant to the radiator.

4. Turn the radiator cap counterclockwise with- out pressing down on it, until it stops. This relieves any pressure remaining in the cool-ing system. And remove the radiator cap bypushing down and turning counterclockwise. Now fill the radiator with clean demineral- ized or distilled water. Continue to add cleandemineralized or distilled water in small quan-tities until the fluid level stays up in theradiator neck. 5. Start the engine, top off the radiator with
water and then add engine coolant to thereservoir until the level is between "LOW"and "FULL".
6. Replace the radiator and reservoir caps and check to be sure the drain cocks are fullyclosed and not leaking.
WARNING: The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper- ate even when the engine is not running.Use extreme caution when working near theblades of the cooling fan so that you are notinjured by a rotating fan blade. As the en-gine coolant temperature decreases, the fanwill automatically shut off. This is a normalcondition. AG060B1-E
SPARK PLUG REPLACEMENT
This operation should only be performed when
the engine is cold.
1. Remove plug lead from the spark plug to be replaced, pulling the lead by the rubber cap. (Pulling the lead may damage the carbonconductor).
2. Clean around the base of the plug to be removed, and install the plug socket ensur-ing that the ceramic insulator does not be-come damaged. Turn the socket anti-clock-wise to remove the plug.

To change the filter, loosen the clamps (1) on the cover. When this is done, the cover can be
lifted off, the old filter removed and the new filterput in its place. Genuine Hyundai replacementparts are recommended. CAUTION: Operating your vehicle without a proper air filter in place can result in excessive enginewear.
G060C02A
Only the correct grade of spark plug should be used. Use of an incorrect grade mayresult in serious engine damage. Prior to installing a spark plug, the gap between the centre and outer electrodesmust be checked and adjusted as neces-sary. Adjustment is facilitated by bending the outer electrode towards or away from the centreelectrode. Under no circumstances shouldattempts be made to adjust the position ofthe centre electrode.
3. Insert the spark plug into the cylinder head and screw by and until the plug contacts theseating area. Tighten the plug with the sock-et by a further 1/2 to 3/4 of a turn only.
4. Replace the plug lead ensuring that the cap is pushed firmly into place. Confirm that thecap is correctly seated by lightly pullingupon it.G060C03A CHAMPION : RC9YC4

WINDSHIELD WIPER BLADES
The wiper blades should be carefully inspected from time to time and cleaned to remove accu-mulations of road film or other debris. To clean the wiper blades and arms, use a clean sponge or cloth with a mild soap ordetergent and water. If the wipers continue to streak or smear the glass, replace them with genuine Hyundai re-placement parts or their equivalent. NOTE:
o Do not operate the wipers on dry glass. This can result in more rapid wear of the wiper blades and may scratch the glass.
o Keep the blade rubber out of contact with petroleum products such as engineoil, gasoline etc.G090A01X-EAT
FILLING THE WASHER RESERVOIR
The washer fluid reservoir supplies fluid to the
windshield washer system.
A good quality washer fluid should be used to fill
the washer reservoir. The fluid level should be checked more frequently during bad weather orwhenever the washer system is in more fre-quent use.
The capacity of the washer reservoir is 2.19
lmp.qts (2.5 Litres).
CAUTION:
o Radiator antifreeze (engine coolant) should not be used in the washer systembecause it will damage the car’s finish.
