Oil Life Indicator - Cadillac 1998 DeVille Owner's Manual

Oil Life 1 iicator
This feature lets you know when to change the engine
oil. It's based on the engine oil temperatures and your
driving patterns. To see the display, press the
INFORMATION (INFO) button until XX OIL LIFE
LEFT appears. If you see 99% OIL LIFE LEFT,
99 percent of your current oil life remains.
The Driver Information Center (DIC) may display a
CHANGE ENGINE OIL message. Always keep a
written record of the mileage and date when you
changed your oil. For more information, see the
Maintenance Schedule booklet. If you see CHANGE
ENGINE OIL, it means that you have less than
10 percent of the oil life left and you should consider
changing your engine oil.
The system should indicate changing the oil between
3,000 miles (5 000
km)
and 7,500 miles (12 500
km).
It may indicate changing the oil before 3,000 miles
(5 000 k m ) depending on your driving habits. If the
vehicle has been driven 7,500 miles (12 500
km),
it will
indicate to change the oil. If you drive in
a dusty area, you
should change your oil every 3,000 miles (5 000 k r n ) or
three months (whichever comes first) unless the display
indicates changing it sooner. The system doesn't check
how much oil you have, so you'll still have to check for
that. To see how, see "Engine Oil" in the Index.

When the oil is changed, you'll need to reset the system.
To reset, display the Oil Life Indicator by pressing the
INFORMATION (INFO) button. Then press and hold
the RESET button until the display shows 100% OIL
LIFE LEFT.
