Change oil soon
The overhead console will warn the
user that it is time to change the oil
based on the number of engine
revolution counts, number of miles
driven or the calendar time since
the last "Oil Life" reset. These
values are constantly updated while
the vehicle is running. When
CHANGE OIL SOON is displayed as a warning, it will be displayed until
the RESET button is pressed and revert back to the previous mode.
Change oil now
The overhead console will warn the
user that the oil needs changing

NOW warning can be cleared by pressing RESET button but will return
after a period of time.
Reset oil life mode
To reset oil minder when the vehicle oil is changed:
1. Press the MODE button
repeatedly until one of these three
messages is displayed; OIL LIFE
