The Oil Life Indicator may say to change the oil sooner thanyour Maintenance Schedule. This can happen if driving conditions, such as short trips in cold weather, cause shorter oil life. Always keep awritten record of the mileage and datewhen you last changed your oil. For more information on when to change your oil, see the Cadillac Maintenance Schedule Booklet. If you see CHANGEOIL SOON, it means that you have less than 10% of your oil life left and you should consider changing your engine oil. If you see CHANGE ENGINE OIL,means the oil life isgone and it you should change the oil right away (certainly within 200 more miles E320 km]). The system should indicate to changethe oil between 3,000 miles (5 000 km) and 7,500 miles (12 500 km), but it may even indicate to change it before 3,000 miles under very severe conditions. It all depends on your driving patterns. If it's been 7,500 miles (12 500 km), it indicates to change the oil. There aretwo things the system doesn't do: It can't sense heavy dust in the places where you drive. If you drive in a dusty area, you should changeyour oil every 3,000 miles (5 000 km) or three months(whichever comes first)unless the display saysto change it even sooner than that. It doesn't check how much oil you have, so you'll still have to check for that. To see how, see "Engine Oil" in the Index. When You've Changed the Oil When new oil is put in, you'll need to reset your system. To do this, display the OIL LIFE INDEX pressing the INFORMATION button. Then by press and hold the RESET buttons until the display shows 100 OIL LIFE LEFT 2-93
