These models come with an oil life indicator system which illuminates a light or a message on the instrument panel that it is time to go for an oil change depending on the consideration of a number of factors with regard to the condition of the oil. This system usually enables the intervals in between the changes to be longer than the generally recommended 3000-mile intervals but constant changes are recommended for durability of the engines. If deciding to make the aforementioned use of the indicator, 1 year or 7,500 miles should not be exceeded between changes. Oil must be refilled often, especially for a preventive measure because when the oil gets old, it embodies the propensity of causing more wear and tear to an engine. Before starting have all the equipment within easy reach and be sure to have rags to clean up spills. Chock the wheels, wheel the car and place it on jackstands safely and wearing heat resisting gloves and other protective gear find the oil drain plug and filter, often exposed to high heat. The engine should be warmed up in order to allow faster oil run out; the oil filler cap and splash shield, if there is any should then be removed. Place an oil pan beneath the engine oil pan then loosen the drain bolt efficiently and check whether the used engine oil contains metal pieces or not, After that, remove the drain plug and clean the area of the drain plug before strengthening it once more. Shift the drain pan beneath the oil filter, unscrew it employing the wrench, and take off the filter with the car tilted to avoid drippings. Remove all the dirt on the mounting surface and make certain that there is no existing gasket present. It is necessary to compare the old and new filters and grease the gasket of the new filter before installing it without applying of the great pressure. Pull out all your tools and materials from the car, then place the vehicle in its lowest position and subsequently fill up the engine with fresh oil via the proper filler cap, to prevent spillage one should use a funnel. Add the right amount of oil, to the feeler gauge touch the dipstick and replace the cap. Engage the engine, then examine for leakage, and fasten if leaking is observed with engine running. Oil level must be checked after certain distance and added if necessary while few days of initial test drive should be kept an eye for any leakage. Neutralise the used oil and get rid of it in an environmentally friendly way, don't pour it down the sink or on the floor. To reset the oil life monitor, the ignition has to be set to the ON status, the remaining quantity of the oil must be displayed, the RESET button has to be pressed for some time until the "OIL LIFE SET TO 100%" sign appears and, finally, the ignition has to be turned off.
