This message is a reminder, after driving about a mile that you have your
turn
signal on.
TRUNK OPEN
This message indicates that your trunk is opcn when the Ignition is ON.
VERY LOW REFRIGERANT
This message means that the Air Conditioning system detects a
refrigerant level that is low enough to cause damage to the A/C
compressor.
To avoid damage, the A/C compressor automatically turns
off and the Electronic Climate Control will automatically switch from
“AUTO” to “ECON” and remain there. Have your
A/C system serviced if
this message appears.
Speed Sensitive Steering (SSS)
This system varies the amount of steering effort proportionate to your
vehicle speed. Steering is easier at
a lower speed for increased
maneuverability and parking ease.
As your vehicle speed increases, the
steering effort
is also increased proportionately. At highway speeds the
amount
of steering effort is greatly increased to provide a manual like
steering feel for maximum control
an enhanced vehicle stability.
Road Sensing Suspension (Northstar Only)
The Road Sensing Suspension automatically controls the ride of your
vehicle.
The system controls damping forces in the shock absorbers and
struts in response to various road and driving conditions. The system is
capable
of making these changes within milli-seconds.
The
Road Sensing Suspension controller is a computer used to control
and monitor the system. The computer receives inputs from vertical
acceleration sensors, wheel
to body position sensors, vehicle speed
sensor, lift and dive signals, and determines optimum strut valving or
(suspension stiffness) for your current operating conditions.
The
computer also receives feedback from the various components 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
“SERVICE RIDE CONTROC’ message will display on the Driver

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
When new oil is put in, you‘ll need to reset your system. To do it, display
the
“OIL LIFE INDEX” by pressing the “Information” button. Then
press and hold the “STORE/RECALL? buttons
until the display shows

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

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.

Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause reduced sound
quality, ruined cassettes, or a damaged mechanism. Cassette tapes should
be stored
in their cases away from contaminants, direct sunlight, and
extreme heat. If they aren’t, they may not operate properly or cause
failure of the tape player.
Your tape player should be cleaned regularly each month or after every
15 hours of use. If you notice a reduction in sound quality, try a known
good cassette to see
if the tape or the tape player is at fault. If this other
cassette has
no improvement in sound quality, clean the tape player.
Clean your tape player with a wiping-action, non-abrasive cleaning
cassette, and follow the directions provided with it.
Cassettes are subject to wear and the sound quality may degrade over
time. Always make sure that the cassette tape is
in good condition before
you have your tape player serviced.
