o The engine oil consumption is strongly effected by the viscosity and quality of oil, engine rpm and driving condition etc. More engine oil may be consumed under severedriving conditions such as high speeds, frequent acceleration and deceleration, compared to normaldriving condition. G050B01A-AAT Recommended Engine Coolant Use a high quality ethylene-glycol coolant in a 50/50 mix with water. The engine coolant should be compatible with aluminum engine parts. Addi-tional corrosion inhibitors or additives should not be used. The cooling sys- tem must be maintained with the cor-rect concentration and type of engine coolant to prevent freezing and corro- sion. Never allow the concentration ofantifreeze to exceed the 60% level or go below the 35% level, or damage to the cooling system may result. Forproper concentration when adding or replacing the engine coolant, refer to the following table.

WARNING:
Do not remove the radiator cap when the engine is hot. When the engineis hot, the engine coolant is under pressure and may erupt through the opening if the cap is removed. Youcould be seriously burned if you do not observe this precaution. Do not remove the radiator cap until theradiator is cool to the touch.

NOTE:
o SAE 5W-20 (5W-30), ILSAC GF-3 engine oil is preferred regardless of regional option and engine variation.
o If SAE 5W-20, ILSAC GF-3 engine oil is not available, secondaryrecommended engine oil for cor- responding temperature rangecan be used.ENGINE 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 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 anduseful life is to be obtained from the vehicle. G030B02O-EAT
Recommended Oil
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.
