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
E320
km]).
The system should indicate to change the oil between 3,000 miles
(5
000
km)
and
7,500
miles
(12
500 km), but it may even indicate
to
change it before 3,000 miles under
very
severe conditions. It all depends
on your driving patterns. If it’s been
7,500
miles
(12
500
km), it indicates
to
change
the
oil.
There are
two
things the system
doesn’t
do:
It can’t sense heavy dust in the places where
you
drive. If
you
drive
in
a
dusty area, you should change your oil
every
3,000
miles
(5
000
km) or
three months (whichever comes first) unless the display says
to
change
it even sooner than that.
It 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 You’ve Changed the
Oil
When
new
oil
is put in, you’ll need
to
reset your system.
To
do this, display
the OIL LIFE INDEX by pressing the INFORMATION button. Then
press and hold the
RESET
buttons until the display shows
