Intelligent Oil-Life Monitor
Your vehicle is equipped with an IntelligentOil-Life Monitor that determines when youshould change the engine oil based on howyour vehicle is used. By using severalimportant factors in its calculations, themonitor helps reduce the cost of owning yourvehicle and reduces environmental waste atthe same time.
This means you do not have to remember tochange the oil on a mileage-based schedule.Your vehicle lets you know when an oilchange is due by displaying a message inthe information display.
The following table provides examples ofvehicle use and its impact on oil changeintervals. It is a guideline only. Actual oilchange intervals depend on several factorsand generally decrease with severity of use.
