CHECKING AND CHANGING THE EN- GINE COOLANT
WARNING: Do not remove the radiator cap when the
engine is hot. When the engine is hot, the engine coolant is under pressure and mayerupt through the opening if the cap isremoved. You could be seriously burned ifyou do not observe this precaution. Do notremove the radiator cap until the radiator iscool to the touch. G050B01A-AAT
Recommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant shouldbe compatible with aluminum engine parts.Additional corrosion inhibitors or additives shouldnot be used. The cooling system must be main-tained with the correct concentration and typeof engine coolant to prevent freezing and corro-sion. Never allow the concentration of anti-freeze to exceed the 60% level or go below the35% level, or damage to the cooling systemmay result. For proper concentration when add-ing or replacing 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 cool-ant should be between the "LOW" and "FULL"lines on the reservoir when the engine is cool.If the level is below the "LOW" mark, addengine coolant to bring it up between "LOW"and "FULL". If the level is low, inspect forcoolant leaks and recheck the fluid level fre-quently. If the level drops again, visit yourHyundai dealer for an inspection and diagnosisof the reason.
7. Refill the crankcase with the recommended
engine oil. Refer to the specification in chap-ter 9 for engine 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 sug-gested that it be placed in a sealed containerand taken to a service station for maybereclaimation. Do not pour the oil on theground or put it in with the household trash.
WARNING: Used motor oil may cause irritation or can-
cer of the skin if left in contact with the skin for prolonged periods of time. Wash yourhands thoroughly with soap and warm wa-ter as soon as possible after handling usedoil.

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.

ways wash thoroughly after any contact. Keep used oils out of reach of children. It is illegalto pollute drains, water courses and soil. Useonly authorized waste collection facilitiesincluding civic amenity sites and garages forthe disposal of used oil and oil filters. If indoubt, 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 pressurizedand coolant may be ejected from the radiatorresulting in scalding. SG050B1-E Coolant recommendations
Only ethylene glycol based coolant with a corro- sion inhibitor suited to aluminium alloy enginecomponents should be used in the cooling sys-tem. No further additives or inhibitors should beused. The coolant specific gravity should bechecked as prescribed in the maintenance sched-ule to ensure adequate frost and corrosion pro-tection. In addition, the engine coolant must bereplaced at the specified interval since the corro-sion inhibitor properties deteriorate with time.It is important to note that whilst an increase in theconcentration of anti freeze gives an increase inthe level of frost protection, a solution which is inexcess of 65% anti freeze will result in reducedfrost 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 willinvalidate the vehicle warranty. NOTE: It is imperative that vehicles fitted with an airconditioning system have a coolant concen-tration of the recommended strength at alltimes. The use of the air conditioning systemwhen the cooling system is filled with wateronly will result in the heater matrix freezingand subsequently bursting.SG050C1-E Engine Coolant LevelThe engine coolant level may be observed through the side of the plastic coolant reservoir(expansion tank) when the engine is cold. If thelevel is below the "LOW" mark, add coolant of thecorrect concentration until the level is betweenthe "LOW" and "Full" marks. If the level fallsbelow the "LOW" mark on a regular basis despitebeing topped up, consult a Hyundai dealer. SG050D1-E To Change the Engine CoolantThe engine coolant should be changed at those intervals specified in the vehicle maintenanceschedule in Section 5. NOTE: Care should be taken to ensure that coolantis not allowed to spill onto the paintworksince the finish may become damaged. Ifcoolant spillage occurs, the affected areashould 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 OPERATIONWHILST THE ENGINE IS HOT SINCEBURN-ING OR SCALDING MAY RESULT.
2. Prepare a suitable receptacle to collect the displaced coolant and position this under theradiator drain tap.
