5VEHICLE MAINTENANCE REQUIREMENTS
2MAINTENANCE AND SER- VICING REQUIREMENTS
SF020A1-E To ensure the continued reliability and safety of the vehicle, certain routinemaintenance operations 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 OwnersManual and the Warranty and Service Passport are adhered to. The new vehicle warranty may be invalidated if the routine maintenance operations are not performed in line with the recommendations outlined andthe safety and durability of the vehicle adversely affected. It is recommended that all mainte- nance operations with the exception of the daily operating checks are en-trusted to a Hyundai dealer to ensure that the latest repair and maintenance procedures and specialized servicingtools are employed. In addition, the use of genuine Hyundai replacement parts will ensure that the vehicle safetyand performance will not be compro- mised. NOTE:
The inspection and testing of cer-
tain electronic fuel injection/enginemanagement and automatic trans- mission control systems requirespecialised electronic equipment specifically designed for Hyundai vehicles. The use of general pur-pose electrical test equipment may result in damage to the control unit microprocessors. SF020C2-E
Specified Scheduled Procedures
The Specified scheduled procedures
are listed in the maintenance charts beginning at page 5-3. The operations specified must be performed at thetime or mileage intervals shown irre- spective of whether the mileage inter- val has been reached before the speci-fied time interval.
Certain lubricants and components
degrade with both time and mileage (e.g. engine oil and brake fluid) and therefore it is not permissable to basethe maintenance schedule upon mile- age alone. It is strongly recommended that the maintenance operations areperformed by the factory-trained or distributor-trained technicians at your Hyundai dealer because of the needfor specialized knowledge and tooling and to ensure that no possibility of invalidating the manufacturers warrantyexists. The maintenance schedules relate to
vehicles operated under normal condi-tions, vehicles which are operated under adverse conditions will require more frequent maintenance which isdescribed at page 5-6.

5ENGINE OIL
SG030A1-E The correct engine oil level is of para-
mount importance. An excessively high or low oil level may result inirreparable damage being sustained by the engine. The engine oil level must be checked on a daily basis orwhenever the vehicle is refuelled, whichever occurs sooner.
In addition, it is imperative that only
an approved grade and specificationof 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 anduseful life is to be obtained from the vehicle.
SG020B1-E The following items should be checked on a daily basis or whenever the vehicle is refuelled, whichever occurssooner.
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 op-
eration.
o Horn operation.
o Warning lamp operation.
o Adjustment and cleanliness of mir- rors.
o Seat and seat belt adjustment and operation.
o Fluid leakage.
The vehicle must not be driven if the daily operating checks indicate that any item of equipment related to the safety or roadworthiness of the ve-hicle is not functioning correctly. DAILY OPERATING CHECKS
G030B02O-EAT Recommended Oil
1. Petrol Engine The engine oil quality should meet the following classification. API SJ, SL or ABOVE, ILSAC GF-3 or ABOVE The oil viscosity should be selected according to the operating environ- ment of the engine by means of thetable shown above. The engine oil recommendations are complete in themselves and the use of additivesis neither required nor recommended. The use of engine oil additives may result in invalidation of the vehiclewarranty.

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 ve-
hicle should be allowed to stand forseveral minutes after the engine has been switched off to allow the oil todrain 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.
!
HGK5004
1.6L/2.0L
2.7LNormal 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 beadded to the degree that the level exceeds the upper mark. Replace the dipstick fully after checking the level.
WARNING:
Be very careful not to touch the
radiator hose when checking the engine oil as it may be hot enough to burn you.
NOTE: SAE 5W-20 (5W-30), ILSAC GF-3 engine oil is preferred regardlessof regional option and engine varia- tion. If SAE 5W-20, ILSAC GF-3 engine oil is not available, sec-ondary recommended engine oil for corresponding temperature range can be used.
