2008 CADILLAC STS Owners Manual

ENGINE OIL LIFE
If your vehicle has this display, it shows the estimated
oil life remaining. If you see 99% ENGINE OIL LIFE
on the display, that means that 99% of the current oil
life remains.
When the oil life is depleted, the CHANGE ENGINE OIL
SOON message will appear on the display. Change
the oil as soon as possible. In addition to the engine oil
life system monitoring the oil life, additional maintenance
is recommended in the Maintenance Schedule in this
manual. SeeScheduled Maintenance on page 6-4
andEngine Oil on page 5-18.
After an oil change, reset the ENGINE OIL LIFE display.
To reset, seeEngine Oil Life System on page 5-21.
The display will show 100% ENGINE OIL LIFE after
it has been reset. Also clear the CHANGE ENGINE OIL
SOON message from the display.

DIC Warnings and Messages
Messages are displayed on the DIC to notify the driver
that the status of the vehicle has changed and that
some action may be needed by the driver to correct
the condition. Multiple messages may appear one after
another.
The text messages are the same for both the base
audio and Navigation systems unless otherwise
indicated.
Some messages may not require immediate action,
but you can press the reset button to acknowledge that
you received the messages and to clear them from
the display.
Some messages cannot be cleared from the DIC
display because they are more urgent. These messages
require action before they can be cleared. Take any
messages that appear on the display seriously
