Driving under these conditions causes engine oil to break down sooner. If any one of these is true for your vehicle, then you need to change your oil and filter every 3,000 miles (5 000 km) or 3 months - whichever occurs first. If none of them is trrire, u-Se the long trip/highway maintenance schedule. Change the oil and filter every 7,500 miles (12 500 km) or 12 months - whichever occurs first. Driving a vehicle with al fully warmed engine under highway conditions will cause engine oil to break down slower. Your vehicle has a unique oil filter element. When installing the filter cap do not exceed 18 Ib ft (25 N-m ). Inspect the condition of the O-ring andreplace if damaged. See your dealer for additional information. What to Do with Used Oil Used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer. Don't let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer's warnings about the use and disposal of oil products. Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never disposeof oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you havea problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help. 5-1a
