help you select the correct oil.
You should look for this on the oil container, and use
only those oils that
display the logo.
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 OIL 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 OIL: 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.
On Northstar 4.6 Liter engine equipped vehicles a ‘CHECK OIL LEVEE
message will appear whenever the oil level’s approximately one quart low.

Downloaded from www.Manualslib.com manuals search engine How To Reset the Oil Life Indicator: After the oil has been changed,
display the ‘OIL LIFE INDEX’ message by pressing the
‘INFORMATION’ button. Then press and hold the
‘STORE/RECALL
button until the display shows ‘100’. This will reset the oil life index. The
message will remain
OFF until the next oil change is needed. The
percentage
of oil life remaining may be check at any item by pressing the
INFORMATION button several times until the ‘OIL LIFE INDEX
message appears.
Engine Block Heater: An engine block heater can be a big help if you
have to park outside in very cold weather, -20” F (-29 “C) or colder. If
your vehicle
has this option, see “Engine Block Heater” in the Index.
What to Do with Used Oil:
A CAUTION
Used engine oil contains things that have caused skin cancer in
laboratory animals. Don’t let used oil stay on your skin for very
long. Clean your skin and nails with soap and water, or a good
hand cleaner. Wash or properlv throw away clothing or rags
containing used engine
oil.
Used oil can be a real threat to the environment. If you change your own
oil, be sure to drain all free-flowing oil from the filter before disposal.
Don’t ever dispose
of oil by pouring it on the ground, into sewers, or into
streams or bodies
of water. Instead, recycle it by taking it to a place that
collects used oil.
If you have a problem properly disposing of your used
oil, ask your dealer, a service station or a local recycling center for help.

AUTOMTIC 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.

Wait at least 30 minutes &ore checking the transaxle fluid level if you
have been driving:
When outside temperatures are above 90’F (32’ C).
At high speed for quite a while.
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 (82OC to 93’C).
Get the vehicle warmed up
by driving about 15 miles (24 km) when
outside temperatures are above
5O0F (loo C). If it’s colder than 5OoF
(lO°C), you
may have to drive longer.

way.
Refer to the Maintenance Schedule to determine what kind
of transaxle
fluid to
use. See “Recommended Fluids and Lubricants” in the Index.
If the fluid level is low, add only enough of the proper fluid to bring the
level into the cross-hatched area
on the dipstick. It doesn’t take much
fluid, generally
less than a pint. Don’t overfill. We recommend you use
only fluid labeled DEXRON@-IIE, because fluids with that label
are
made especially for your automatic transaxle. Damage caused by fluid
other than DEXRON@-IIE is not covered
by your new vehicle warranty.
After adding fluid, recheck the fluid level as described under “How to
Check.”

How To Reset Transaxle Fluid Change Indicator: 4.6L (Northstar)
Your vehicle is equipped with a transaxle fluid change indicator.
A
“CHANGE TRANS FLUID” message will display on the Information
Center
when the power train computer determines that the transaxle
fluid needs to be changed or at each 100,000 miles
(160,000 km) interval,
whichever occurs first. When this message appears, change the t\
ransaxle
fluid and reset the transaxle fluid life indicator
as follows:
Turn the key “ON” with the engine stopped.
Press and hold the “OFF” and “REAR DEFOG” buttons on the
climate control simultaneously
until the “TRANS FLUID RESET”
message appears
in the Information Center (between 5 and 20
seconds).
ENGINE COOLANT
The following explains your cooling system and how to add coolant when
it is low. If you have
a problem with engine overheating, see “Engine
Overheating” in the Index.
The proper coo’ It for
your Cadillac will:
Give freezing protection down to -34°F (-37’C) .
Give boiling protection up to 262 ” F (128 ” C) .
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights work as they should.
What to Use:
Use a mixture of one-half clean water (preferably distilled) and one\
-half
antifreeze that meets
“GM Specification 1825-M,” which won’t damage
aluminum parts. You can also use a recycled coolant conforming to
GM
Specification 1825-M with a complete coolant flush and refill. Use GM
Engine Coolant Supplement (sealer) with any complete coolant c\
hange.
If you use these, you don’t need to add anything else.
