Oil Life Indicator
Your Cadillac has a Driver Information Cente.r with an Oil Change
Indicator feature. This tclls you when
you need to change your engine oil.
It’s based upon the engine oil temperatures and your driving patterns.
. ...
I To see the display,
press
the Information
button several times
until “ OTL LIFE
INDEX” appears.
You’ll see how much oil life you have left,
as a percentage. So, if you see
“95 OIL LIFE INDEX,” for example, that means that the way you’re
driving your car,
95% of your current oil life is still left.
The
“OIL LIFE INDEX” 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 “Maintenance
Schedule.”
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
[320 km]).

Downloaded from www.Manualslib.com manuals search engine The system probably will say to change the oil between 3000 miles (5000
km) and 7500 miles (12500
km), but it may even say to change it before
3000 under
very severe conditions. It all depends on your driving
patterns. If it’s been 7500 miles
(12500 km) it will say to change oil.
There are two things the system doesn’t do:
It can’t sense heavy dust in the places whcre you drive. If you drive in
a dusty area, you should change your oil every 3000 miles (5000 krn)
or
3 months (whichever comes first), unless thc display says to change
it even sooner than that.
0 It doesn’t check how much oil you have, so you’ll still have to check
Also, for the system
to work right, it is important that you use SG oil, as
discussed earlier.
for that.
To see
how, see Index under “Engine Oil.”
When You’ve Changed the Oil

the
“OIL LIFE INDEX” by pressing the “Information” button. Then

Speed Sensitive Suspension
The Speed Sensitive Suspension automatically controls the firmness of
your Cadillads ride. An actuator in each of the four struts will change
ride firmness depending
on vehicle speed and other driving conditions.
As
the vehicle speed increases, the firmness of the suspension changes to
one or three damping modes “Comfort”, for speeds !ess than 40 mph,
“Normal” for speeds between
40 and 60 rnph, and “Firm” for speeds
greater than 60 mph.
The system also stiffens damping during hard
acceleration, braking and cornering ,for increased control,
A computer is used to control and monitor the system. The computer
receives speed, acceleration and determines optimum mode strut valving
(or suspension stiffness) for your current operating conditions. The
computer also receives feedback from the struts to determine proper
system operation.
If the computer receives an incorrect feedback from
the system, an error code will
be set in memory and a message

However, you can use
SAE 5W-30 if it's going to be colder than 60°F
(16"

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.

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
