The Speed Sensitive Suspension automatically controls the firmness of
your Cadillac’s 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 less than
40 mph,
“Normal” for speeds between
40 and 60 mph, 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 v\
alving
(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
“SERVICE RIDE CONTROC‘
will be displayed until the problem is
corrected. If this message should appear, have your vehicle serviced at
your Cadillac dealer at your earliest convenience.
Electronic Level Control
This keeps your car level.
The ignition has
to be “ON” for the level control to work. When you turn
the ignition off, you may hear the level control exhausting. The system
consists of an electronic height sensor, a small electric air compressor,
and air adjustable shock absorbers mounted on the rear of
the vehicle.
If the system has a slight leak, the air compressor
will run frequently for a
few seconds each time.
For a massive air leak, the air compressor
will stay on for approximately 7
minutes. You should see your dealer for service, but you can keep driving
your Cadillac, though.

Downloaded from www.Manualslib.com manuals search engine What to Add:
When you do need brake fluid, use only DOT-3 brake fluid -- such as
Delco Supreme
11s (GM Part No.1052535). Use new brake fluid from a
sealed container only.
REPLACING 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 Freedoms battery. You never have to
add water to one
of these. When it’s time for a new battery, we
recommend a Delco Freedoms battery. Get one that has the catalog
number shown on the original battery’s label.

Downloaded from www.Manualslib.com manuals search engine What You’ll find in the Index:
+ A list of all PSPs published by Cadillac in a model year (1990 or later). PSPs
covering all models of Cadillac cars are listed in the same index. I-
+ ordering information so you can buy the specific PSPs you may want.
+ Price information for PSPs you may want to buy.
How You Can Get an Index:
Indexes are published periodically. Most of the PSPs which could potentially apply to
the most recent Cadillac models will by listed in the last qu\
arterly publication for that
model year. This means you
may want to wait until the end of the model year before
ordering an index, if you are interested in buying
PSPs pertaining to a current model year
vehicle.
Some
PSPs pertaining to a particular model year vehicle may be published on later
years, and these would
be listed in the later year’s index. When you order an index for a
model year that is not over yet, we’ll send you the most \
recently published quarterly
issue. You can specify an index for
an earlier model year, but not before 1990.
Cut out the order form, fill it out, and mail it. We will see to it that an index is mailed to
you. There is no charge for indexes for the 1990-1993 model years.
Toll-Free Telephone Number
If you want an additional ordering form for an index or a subscription, just call toll-fiee
and we’ll be happy to send you one. Automated recording equipment will take your
name and mailing address. The number to call is
1-800-551-4123.
Copies at Participating Dealers
Copies of Indexes and individual PSPs are at your Cadillac dealership. You can ask to
see them.
A VERY IMPORTANT REMINDER: These PSPs are meant for technicians. They are
not meant
for the ‘da-it-yourselfer’. Technicians have the equipment, tool\
s, safety
instructions, and
training to do a job quickly and safely.
Cadillac reserves the right to change these procedures without \
notice after November,
1991.
Cadillac Owner’s Manuals and Service Publications
You can get these by using the order form. Additionally, past model Owner’s Manuals
and Service Information Manuals are available for a minimum of ten model years and
frequently much longer. Credit card orders may
