B010A02A-GAT FUEL RECOMMENDATIONS Use Unleaded Gasoline Unleaded gasoline with a Pump Octane Rating of 87 (Research Octane Number 91) or highermust be used in Hyundai vehicle. If leaded gaso-line is used, it will cause the catalytic converter tobecome ineffective and the emission controlsystem to malfunction.This can also result in increased maintenanceexpense. To avoid accidental use of leaded fuel,the large nozzle used with leaded gasoline atservice stations can not be inserted into fuel tankopening of Hyundai vehicle. NOTE:
o For some countries, Hyundai vehicles are
designed to use leaded gasoline. Whenyou are going to use leaded gasoline, askto Hyundai dealer whether leaded gaso-line in your vehicle is available or not.
o Octane Rating of leaded gasoline is same with unleaded one.
B010B01A-AAT What About Gasohol? Gasohol (a mixture of 90% unleaded gasoline and 10% ethanol or grain alcohol) may be usedin your Hyundai. However, if your engine devel-ops driveability problems, the use of 100% un-leaded gasoline is recommended. Fuels withunspecified quantities of alcohol, or alcoholsother than ethanol, should not be used. B010D01S-AAT Do not Use Methanol Fuels containing methanol (wood alcohol) should
not be used in your Hyundai. This type of fuel canreduce vehicle performance and damage com-ponents of the fuel system. CAUTION: Your Hyundai's New Vehicle Limited War-ranty may not cover damage to the fuel sys-tem and performance problems that arecaused by the use of methanol or fuels con-taining methanol. B010E01A-AAT Gasolines for Cleaner AirTo help contribute to cleaner air, Hyundai recom- mends that you use gasolines treated with deter-gent additives, which help prevent deposit for-mation in the engine. These gasolines will helpthe engine run cleaner and enhance performanceof the Emission Control System. B010F01A-AAT Operation in Foreign Countries If you are going to drive your Hyundai in another country, be sure to:
o Observe all regulations regarding registra-
tion and insurance.
o Determine that acceptable fuel is available. B020A01S-GAT BREAKING IN YOUR NEW HYUNDAI During the First 2,000 Km (1,200 Miles) No formal "break-in" procedure is required with your new Hyundai. However, you can contributeto the economical operation and durability of yourHyundai by observing the following recommen-dations during the first 2,000 km (1,200 miles).
o Don't drive faster than 88 km/h (55 mph).
o While driving, keep your engine speed (rpm, or revolutions per minute) between 2,000 rpmand 4,000 rpm.
o Use moderate acceleration. Don't start, de- press the accelerator pedal fully.

CONTROLS AND EQUIPMENT1- 1
The use of leaded fuel in this vehicle will result in irreversible pollution of the catalyst element.Such pollution will prevent correct operation ofthe catalyst and give rise to increased operatingtemperatures leading to the catalyst elementmelting and restricting the exhaust flow alongwith an increase in exhaust emission levels. CAUTION: The vehicle warranty will not extend to dam-age arising from the use of incorrect fuels. Overseas Operation: When the vehicle is to be operated overseas, the vehicle operator should establish that a suitablefuel for satisfactory operation of the vehicle isavailable.
B020A01S-EAT RUNNING INThe longevity and performance of the vehicle are greatly affected by the care exercised during thefirst 1,000 miles of motoring. Because of modernmanufacturing techniques, rigid guidelines re-garding maximum road speeds have becomeunnecessary. However, certain precautionsshould be observed in order to obtain the bestpossible performance and useful life from thevehicle.
1) Do not race the engine without a load (i.e
revving the engine in neutral).
2) During the first 500 miles the maximum en- gine speed should be restricted to 3,000 rpmand gradually increased thereafter.
3) Avoid prolonged constant speed operation. The internal components of the engine willbecome more quickly run in if the operationspeed is varied during the running in period.
4) Never allow the engine to labour. Use the gearbox freely and avoid large throttle open-ings when the engine speed is below 1,500rpm.
5) Avoid rapid acceleration and maximum throttle openings.
6) Avoid harsh braking during the first 100 miles of urban motoring or 1,000 miles ofmotorway driving to allow the friction facingsof the brake pads and shoes to bed againstthe discs and drums properly.
7) No trailer towing should be undertaken dur- ing the running in period.

EQUIPMENT
B010E01A-EAT PETROLS FOR CLEANER AIR To help contribute to cleaner air, Hyundai recom- mends that you use petrols treated with deter-gent additives, which help to prevent depositformation in the engine. These petrols will helpthe engines run cleaner and the Emission Con-trol System performance.
Unleaded fuel with a Reasearch Octane Number(RON) of 91 or higher must be used in thisvehicle.To prevent accidental charging of the fuel tankwith leaded fuel, a small diameter filler neckalong with a restrictor flap are fitted to ensure thatonly unleaded fuel pump nozzles may enter thefiller neck. However, care must be exercisedwhen refuelling the vehicle tank from jerry cansor by means of a funnel that the fuel being usedis unleaded.
B010A01A-EAT FUEL RECOMMENDATIONS THIS VEHICLE MUST ONLY BE OPERATED WITH UNLEADED FUEL.SERIOUS DAMAGE WILL RESULT FROMTHE USE OF LEADED FUEL.

SG020B1-E DAILY OPERATING CHECKSThe 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 equipmentrelated to the safety or roadworthiness of thevehicle is not functioning correctly. SG030A1-E ENGINE OILThe correct engine oil level is of paramount importance. An excessively high or low oil levelmay result in irreparable damage being sus-tained by the engine. The engine oil level must bechecked on a daily basis or whenever the vehicleis refuelled, whichever occurs sooner.In addition, it is imperative that only an approvedgrade and specification of oil is used to avoid thepossibility of serious engine damage and prema-ture wear. The use of "budget price" oil is a falseeconomy that must be avoided if the maximumreliability and useful life is to be obtained from thevehicle.
SG030B02GK-E Recommended Oil A multi grade oil having a specification which meets A.P.I. specification of SH, SG or above isrecommended. The oil viscosity should be se-lected according to the operating environment ofthe engine by means of the table shown below.The engine oil recommendations are complete inthemselves and the use of additives is neitherrequired nor recommended. The use of engineoil additives may result in invalidation of thevehicle warranty.
