Intelligent Oil Life Monitor™

Your vehicle is equipped with an Intelligent Oil Life Monitor™ that determines when the engine oil should be changed based on how your vehicles is used. By using several important factors in its calculations, the monitor helps reduce the cost of owning your vehicle and reduce environmental waste at the same time. This means you won’t have to remember to change the oil on a mileage-based schedule; the vehicle lets you know when an oil change is due by displaying ENGINE OIL CHANGE DUE or OIL CHANGE REQUIRED in the message center. The following table is intended to provide examples of vehicle use and its impact on engine oil change intervals; it is provided as a guideline only.
Actual engine oil change intervals will depend on several factors and will generally decrease with severity of use.
