SAE 1OW-30
As shown in the viscosity chart, SAE low-30 is best for your vehicle.
However, you can use
SAE 5W-30 if it's going to be colder than 60°F
(16"
C) before your next oil change. When it's very cold, below 0°F
(-18OC), you should use SAE 5W-30.
These numbers on an
oil container show its viscosity, or thickness. Do not
use other viscosity oils such as
SAE 1OW-40 or SAE 20W-50.

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.

Engine Block Heater: An engine block heater can be

vehicle has this option, see “Engine Block Heater”

What
to Do with Used Oil:
1 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 - ‘J;
long. Clean your skin and nails with soap and water, or a good -
hand cleaner. Wash or properly throw away clothing or rags

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.

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.

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 coolant for your Cadillac will:
Give freezing protection down to -34” F (-37” C) .
0 Give boiling protection up to 262OF (128O C) .
0 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
280
Downloaded from www.Manualslib.com manuals search engine Specification 1825-M with a complete coolant flush and refill. Use GM
Engine Coolant Supplement (sealer) with any complete coolant change.
If you use these, you don’t need to add anything else.
Adding only plain water to your cooling system can be
dangerous. Plain water, or some other liquid like alcohol, can
boil before the proper coolant mix will. Your vehicle’s cwlant
warning system is set for the proper coolant mix With plain
water or the wrong mix, your engine could get too hot but you
wouldn’t get the overheat warning. Your engine could catch fire
and you or others could be burned. Use a 50/50 mix of dean
water and a proper anti€reeze,

REPUCING BRAKE SYSTEM PARTS
The braking system on a modern vehicle is complex. Its many parts have
to be
of top quality and work well together if the vehicle is to have really
good braking. Vehicles
we design and test have top-quality GM brake
parts in them, as your Cadillac does when it is new. When you replace
parts
of your braking system -- for example, when your brake linings wear
down and you have to have new ones put in
-- be sure you get new
genuine GM replacement parts. If you don’t, your brakes may no longer
work properly.
For example, if someone puts in brake linings that are
wrong for your vehicle, the balance between your front and rear brakes
can change, for the worse. The braking performance you’ve come to
expect can change in many other ways
if someone puts in the wrong
replacement brake parts.
BATTERY
Every new Cadillac has a Delco Freedom@ battery. You never have to
add water to one of these. When it’s time for a new battery, we
recommend a Delco Freedom@ battery. Get one that has the catalog
number shown
on the original battery’s label.

USING SOLVENT-TYPE CLEANER ON

First, see if you have to use solvent-type cleaner at all. Some spots and
stains will clean
off better with just water and mild soap.
If you need to use it, then:
0 Gently scrape excess soil from the trim material with a clean, dull
knife
or scraper. Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start
at the outside of the
stain, “feathering” toward the center. Keep changing to
a clean
section
of the cloth.
0 When you clean a stain from fabric, immediately dry the area with an
air hose, hair dryer, or heat lamp
to help prevent a cleaning ring. (See
the previous
NOTICE.)
