computer receives an incorrect feedback from the system, an error code will
be set in memory and a “SERVICE RIDE CONTROE’ message will display
on the Driver Information Center. If

Oil Life Indicator
This feature lets you know when to change your engine oil. It’s based
upon the engine oil temperatures and your driving patterns.
To see
the display,
press the Information
button several times until
“XXX OIL LIFE
LEFT” appears.
You’ll see
now much oil life you have left, as a percentage. So, if you see
“95 OIL LIFE LEFT,’’ for example, that means that the way you’re
driving your car,
95% of your current oil life is still left.
The Oil Life Indicator may
say to change the oil sooner than your
maintenance schedule.
This can happen if driving conditions, such as
short trips in cold weather, cause shorter oil
life. Always keep a written
record of the mileage and date
when you last changed your oil. For more
information on when to change your oil, see
the Cadillac Maintenance
Schedule Booklet.
If you see “CHANGE OIL SOON,”
it means that you have less than 10%
of your oil life left, and you should consider changing your engine oil.
If you see “CHANGE ENGINE
OIL,” it means the oil life is gone
and you should change the oil right away (certainly
within 200 more
miles
[320 km]).
