Oil Life Indicator This feature lets you knowwhen to change your engine oil. It's based upon the engine oil temperatures and your drivingpatterns. To see the display, press the Information button several times until "XX OIL LIFE LEFT" appears. You'll see how much oil life you have as apercentage. So, if you see left, "95 OIL LIFELEFT," for example, that means that theway you're driving yourcar, 95% of your current oil life is still left. The Oil LifeIndicator may say to change the oil sooner than your maintenance schedule. This can happen if driving conditions, such as short trips in coldweather, cause shorter oil life. Always keep a written record of the mileage and date when you last changed your oil.For more information on when to change your oil, see theCadillac Maintenance Schedule Booklet. If you see "CHANGE OIL SOON," it meansthat you have lessthan 10% of your oillife left, and you should consider changing your engine oil. If you see "CHANGE ENGINE OIL," it means the oil life is gone and you should change the oil rightaway (certainly within200 more miles [320 km]). The system probably will say change the oil between 3000 miles (5000 to km) and 7500 miles (12500km), but it may even sayto change it before 3000 under very severe conditions.It all depends on your driving patterns. If it's been 7500 miles (12500km) it always says change the oil. to 151
