VEHICLE MAINTENANCE REQUIREMENTS 5-1
SF020A1-E MAINTENANCE AND SERVICINGREQUIREMENTS To ensure the continued reliability and safety of the vehicle, certain routine maintenance opera- tions are required at specific mileage or time intervals. It is the responsibility of the vehicle owner to ensure that the maintenance schedules shown in both this Owners Manual and the Warranty and Service Passport are adhered to. The new vehicle warranty may be invalidated if the routine maintenance operations are not per- formed in line with the recommendations outlined and the safety and durability of the vehicle ad- versely affected. It is recommended that all maintenance opera- tions with the exception of the daily operating checks are entrusted to a Hyundai dealer to ensure that the latest repair and maintenance procedures and specialized servicing tools are employed. In addition, the use of genuine Hyundai replacement parts will ensure that the vehicle safety and performance will not be compro- mised.

NANCE REQUIRE- MENTS NOTE: The inspection and testing of certain elec- tronic fuel injection/engine management and automatic transmission control systems re- quire specialised electronic equipment spe- cifically designed for Hyundai vehicles. The use of general purpose electrical test equip- ment may result in damage to the control unit microprocessors. SF020C1-E Specified Scheduled ProceduresThe Specified scheduled procedures are listed in the maintenance charts beginning at page 5- 2. The operations specified must be performed at the time or mileage intervals shown irrespec- tive of whether the mileage interval has been reached before the specified time interval. Certain lubricants and components degradewith both time and mileage (e.g. engine oil and brake fluid) and therefore it is not permissable to base the maintenance schedule upon mile- age alone. It is strongly recommended that the maintenance operations are performed by the factory-trained or distributor-trained technicians at your Hyundai dealer because of the need for specialized knowledge and tooling and to en- sure that no possibility of invalidating the man- ufacturers warranty exists. The maintenance schedules relate to vehiclesoperated under normal conditions, vehicles which are operated under adverse conditionswill require more frequent maintenance which is described at page 5-4. SF030B1-E SERVICE HISTORY It is important that all scheduled maintenance services are recorded in the warranty and ser- vice passport to ensure that proof of mainte- nance is available when warranty service is required.

SG020B1-E DAILY OPERATING CHECKS The following items should be checked on a daily basis or whenever the vehicle is refuelled, which- ever occurs sooner.
o Engine oil level.
o Engine coolant level.
o Power steering fluid level.
o Brake fluid level.
o Windscreen washer fluid level.
o Battery condition.
o Tyre condition and pressures.
o Operation and cleanliness of all lighting equip-
ment.
o Windscreen wiper and washer operation.
o Horn operation.
o Warning lamp operation.
o Adjustment and cleanliness of mirrors.
o Seat and seat belt adjustment and operation.
o Fluid leakage. The vehicle must not be driven if the daily oper- ating checks indicate that any item of equipment related to the safety or roadworthiness of the vehicle is not functioning correctly. SG030A1-E ENGINE OIL The correct engine oil level is of paramount importance. An excessively high or low oil level may result in irreparable damage being sus- tained by the engine. The engine oil level must be checked on a daily basis or whenever the vehicle is refuelled, whichever occurs sooner. In addition, it is imperative that only an approved grade and specification of oil is used to avoid the possibility of serious engine damage and prema- ture wear. The use of "budget price" oil is a false economy that must be avoided if the maximum reliability and useful life is to be obtained from the vehicle.
SG030B02GK-E Recommended Oil A multi grade oil having a specification which meets A.P.I. specification of SH, SG or above is recommended. The oil viscosity should be se- lected according to the operating environment of the engine by means of the table shown below. The engine oil recommendations are complete in themselves and the use of additives is neither required nor recommended. The use of engine oil additives may result in invalidation of the vehicle warranty.

See the lubrication chart on the page 9-3. NOTE:
o The use of a 5W-20 multi grade oil is not
recommended for sustained high speed use.
o When replacing or adding the oil, below SAE 10W-30 is recommended. Using a high viscosity oil of SAE 15W-40 and over makes malfunction of VVT engine when the engine is cool. SG030D1-E ENGINE OIL REPLENISHMENT If the indicated oil level is at or below the lower mark of the dipstick, oil should 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 counterclockwise direction and pour engine oil into the engine. Before checking the level again, allow several minutes for the oil to drain into the sump. Replace the oil filler cap rotating it in a clockwise direction until tight. The quantity of oil required to raise the level from the minimum to maximum level is approximately 1 litre.
SG030C1-E Engine Oil Level
The engine oil level should be checked with the engine at normal operating temperature and the vehicle parked upon level ground. Prior to checking the level, the vehicle should be allowed to stand for several minutes after the engine has been switched off to allow the oil to drain back to the sump. Withdraw the dipstick and wipe it with a clean rag. Replace the dipstick fully and withdraw again when the oil level may be read from the stick. Normal oil level is indicated when the oil is present between the two marks on the stick. It is not necessary to add oil if the level is above the lower mark and in any case, oil must not be added to the degree that the level exceeds the upper mark. Replace the dipstick fully after check- ing the level.

5. Remove the oil filter by rotating counterclock- wise, using a proprietary oil filter removal toolif necessary. Note that the oil filter will contain approximately 0.5 litres of oil and this should be collected in a suitable receptacle.
6. Install a new oil filter having smeared the
sealing ring with clean oil and rotating clock- wise until the filter contacts the mounting and then a further one half turn. Do not over- tighten. Tightening torque: 1.2 ~ 1.6 kgf.m.
7. Pour the specified quantity of the recom- mended oil into the engine and replace the filler cap. Start the engine and ensure that no oil leaks exist. Turn off the engine and after a couple minutes, recheck the oil level.
WARNING: Prolonged and repeated contact with used engine oils may result in serious skin disor- ders including dermatitis and cancer. Avoid contact with skin as far as possible and al-
G040A02GK-EAT ENGINE OIL AND FILTER REPLACEMENT The engine oil and filter must be changed at the time or mileage interval specified in the mainte- nance schedule. If the vehicle is operated under severe or adverse conditions, the oil and filter must be replaced more frequently. To replace the oil and filter, proceed as follows:
1. Ensure that the engine is at normal operating
temperature and park the vehicle on level ground with the parking brake securely ap- plied and the engine turned off.
2. Open the bonnet and remove the oil filler cap.
3. Prepare a suitable receptacle to collect the displaced oil and remove the drain plug fromthe sump.
ZG030E1-A 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 normal driving. The cause of oil consumption in a normal engine are as follows;
o Engine oil is used to lubricate pistons, 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 during en- gine operation sucks some of the oil into the combustion chamber. This oil with some oil of the cylinder wall is burned by the high temperature combustion gases during the combustion process.
o The engine oil consumption is strongly ef- fected by the viscosity and quality of oil, engine rpm and driving condition etc. The engine oil is more consumed under se- vere driving conditions such as high speeds and frequent acceleration and deceleration than normal driving condition.

ways wash thoroughly after any contact. Keep used oils out of reach of children. It is illegal to pollute drains, water courses and soil. Use only authorized waste collection facilities including civic amenity sites and garages for the disposal of used oil and oil filters. If in doubt, contact the local authority for dis- posal instructions. SG050A1-E ENGINE COOLANT CHECKING AND REPLACING 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. SG050B1-E Coolant recommendations
Only ethylene glycol based coolant with a corro- sion inhibitor suited to aluminium alloy engine components should be used in the cooling sys- tem. No further additives or inhibitors should be used. The coolant specific gravity should be checked as prescribed in the maintenance sched- ule to ensure adequate frost and corrosion pro- tection. In addition, the engine coolant must be replaced at the specified interval since the corro- sion inhibitor properties deteriorate with time. It is important to note that whilst an increase in the concentration of anti freeze gives an increase in the level of frost protection, a solution which is in excess of 65% anti freeze will result in reduced frost protection and engine overheating. There- fore the recommended concentration of 50% should not be exceeded for general use. The use of methanol based anti freeze com- pounds may result in engine overheating and will invalidate the vehicle warranty. NOTE: It is imperative that vehicles fitted with an air conditioning system have a coolant concen- tration of the recommended strength at all times. The use of the air conditioning system when the cooling system is filled with water only will result in the heater matrix freezing and subsequently bursting.SG050C1-E Engine Coolant Level The engine coolant level may be observed through the side of the plastic coolant reservoir (expansion tank) when the engine is cold. If the level is below the "LOW" mark, add coolant of the correct concentration until the level is between the "LOW" and "Full" marks. If the level falls below the "LOW" mark on a regular basis despite being topped up, consult a Hyundai dealer. SG050D1-E To Change the Engine Coolant The engine coolant should be changed at those intervals specified in the vehicle maintenance schedule in Section 5. NOTE: Care should be taken to ensure that coolant is not allowed to spill onto the paintwork since the finish may become damaged. If coolant spillage occurs, the affected area should be rinsed thoroughly with water.
1. Park the vehicle on level ground and ensure
that the parking brake is firmly applied, and the engine allowed to cool. DO NOT ATTEMPT THIS OPERATION WHILST THE ENGINE IS HOT SINCE BURN-ING OR SCALDING MAY RESULT.
2. Prepare a suitable receptacle to collect the displaced coolant and position this under the radiator drain tap.

OWNER MAINTENANCE
6-8 CAUTION: Sparking plugs must only be cleaned using purpose designed equipment. Wire brushing may damage the centre electrodeinsulator causing mis-firing to occur. Only the correct grade of sparking plug should be used. Use of an incorrect grade may result in serious engine damage.
3. With the heater temperature control set to the
"HOT" position, remove the radiator cap and open the radiator drain tap.
4. When the engine coolant has drained com- pletely, close the drain tap ensuring that this is not over tightened.
5. Prepare a suitable quantity of new engine
coolant (refer to section 9) and pour this into the radiator.
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 replenish the coolant reservoir.
7. When the engine is hot, check to ensure that no coolant leaks are present.
WARNING: The cooling fan is controlled by engine cool- ant temperature and may sometimes operate even when the 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, the fan will automati- cally shut off. This is a normal condition. G060B02GK-EAT SPARKING PLUG REPLACEMENT This operation should only be performed when the engine is cold.
1. Remove the engine rocker cover.NOTE: It is recommended that the spark plug for Engine 2.7L should be changed by an autho- rized Hyundai dealer.
2. Remove plug lead from the sparking plug to
be replaced, pulling the lead by the rubber cap. (Pulling the lead may damage the carbon conductor).
3. Clean around the base of the plug to be removed, and install the plug socket ensuring that the ceramic insulator does not become damaged. Turn the socket counterclockwise to remove the plug.
