menu items can be displayed by pressing the
vehicle information button:
OIL LIFE REMAINING
If the vehicle has this display, it shows the
estimated oil life remaining. If you see 99% OIL
LIFE REMAINING on the display, that means that

When the oil life is depleted, the CHANGE ENGINE
OIL SOON message will appear on the display.
You should change the oil as soon as possible.
In addition to the engine oil life system monitoring
the oil life, additional maintenance is recommended
