MAINTENANCE
Intelligent Oil-Life Monitor
Your vehicle has an Intelligent Oil-Life
Monitor that determines when you should
change the engine oil based on how your
vehicle is used. By using several important
factors in its calculations, the monitor helps
reduce the cost of owning your vehicle and
reduces environmental waste at the same
time.This means you do not have to remember to
change the oil on a mileage-based schedule.
Your vehicle lets you know when an oil
change is due by displaying a message in
the information display.
The following table provides examples of
vehicle use and its impact on oil change
intervals. It is a guideline only. Actual oil
change intervals depend on several factors
and generally decrease with severity of use.
