ENGINE OIL
It's a good idea to check your engine oil every time you get fuel. In order
to get an accurate reading, the
oil must be warm and the vehicle must be
on
level ground.

GM Goodwrench@ oil (in Canada, GM Engine Oil) meets all the
requirements for your vehicle.
Engine Oil Additives: Don’t add anything to your oil. Your Cadillac
dealer is ready to advise
if you think something should be added.
When to Change Engine Oil: Your vehicle is equipped with an engine oil
life index (EOLI) feature as part
of the Driver Information Center
display (DIC). Oil change intervals are determined by the EOLI and will
usually fall at, or between, the
two recommended alternative intervals of
3,000 miles (5,000 kilometers) and 7,500 miles (12,500 kilometers), but
could be shorter than
3,000 miles (5,000 kilometers) under some very
severe driving conditions shown in Schedule I. The system will also
indicate the need for an oil change if
7,500 miles (12,500 kilometers) or
one year has passed.
Engine
oil life remaining is displayed through engine data as the ‘OIL
LIFE INDEX’ and as a ‘CHANGE ENGINE OIC message. The
‘OIL
LIFE INDEX’ display includes a number between 0 and 100. This is the
percentage
of oil life REMAINING based on driving conditions and
mileage driven since the last time of the oil life indicator was reset. When
the remaining oil life is less than
lo%, a ‘CHANGE OIL SOON’ message
will appear. This is a reminder to schedule an engine oil change. When
the oil life index reaches
0, the ‘CHANGE ENGINE OIC message will
appear. This indicates that no oil life remains and the oil should be
changed
as soon as possible, but certainly within the next 200 miles (320
km).
The EOLI will not detect excessively dusty conditions or engine
malfunctions which may effect the
oil. If you drive in dusty areas, change
the engine oil after every
3,000 miles (5,000 kilometers) or 3 months
(whichever comes first), unless instructed to do
so sooner by the DIC.

AUTOMATIC TRANSAXLE FLUID
When to Check and Change:
A good time to check your automatic transaxle fluid level is when the
engine oil is changed. Refer to the Maintenance Schedule to determine
when to change your fluid. See “Scheduled Maintenance Services” in the
Index.
How to Check
Because this operation can
be a little difficult, you may choose to have
this done at a Cadillac dealership Service Department.
If you do it yourself, be sure to follow all the instructions here, or you
could get a false reading on the dipstick.

have been driving:
0 When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal operating
temperature, which is
180’F to 200°F (82°C to 93OC).
Get the vehicle warmed up by driving about 15 miles (24 km) when
outside temperatures are above
50°F (10” C). If it’s colder than 50’F
