This means that the life of your engine oil has expired and it should be

serviced at your Cadillac dealer at your earliest convenience.
Oil Life Indicator
Your Cadillac has a Driver Information Cente.r with an Oil Change
Indicator feature. This tclls you when
you need to change your engine oil.
It’s based upon the engine oil temperatures and your driving patterns.
. ...
I To see the display,
press
the Information
button several times
until “ OTL LIFE
INDEX” appears.
You’ll see how much oil life you have left,
as a percentage. So, if you see
“95 OIL LIFE INDEX,” for example, that means that the way you’re
driving your car,
95% of your current oil life is still left.
The
“OIL LIFE INDEX” 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 “Maintenance
Schedule.”
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]).

See the Maintenance Schedule for more
on this. Things that are
especially important in trailer operation are automatic transaxle fluid

Be sure the posted octane is at least 91.
If the octane is less than 91, you
