OIL LIFE INDICATOR Your Cadillac has an Oil LifeIndicator feature. This tells you when you need to change your engine oil. It's basedupon the engine oil temperatures and your driving patterns. Your Oil Life Indicator may sayto change the oil sooner thanyour maintenance schedule. This can happen if driving conditions, such as short trips in coldweather, cause shorter oil life. Alwayskeep a written record of the mileage and date when you last changed your oil. more For information on when to change your oil,see theCadillac Maintenance Schedule Booklet. The system probablywill say to change the oil between3000 miles (5000 km) and 7500 miles (12500 k )but it may even say to change it m, before 3000 miles under severe conditions. It all depends onyour driving patterns. (If it doesn't, or if it doesn't even light then something is up, wrong. You will need to have it serviced.) There aretwo things the system won'tdo: It can't sense heavy dust inthe places where you drive.If you drive in a dusty area, you should change your oil every 3000 miles (5000 k ) 3 months (whichever comes first), m or unless the "CHANGEOIC' light comes sooner. on It doesn't check how much oil you have you will still haveto check for so that. To check it, see theIndex under "EngineOil." When You've Changed the Oil When new oil is in, you'llneed to reset your system. To do that, turn put the ignition switchto the"ON" position withthe engine stopped. Fully depress andrelease the accelerator pedal 3 times within5 seconds. If the "CHANGE OIC' light comeson and stays on for5 seconds, it did not reset.You'll need to reset thesystem again. 145
