Traction Control System Warning Light (Option)
WER
When your traction
control system
is
working, the message
“TRACTION
ACTIVE”
will appear
in your information
center. This means
that slippery road
conditions may exist.
The “TRACTION
OFF” warning light
means that the system
is not working. This
warning light may
come on for the
following reasons:
If your transaxle overheats, the traction control system automatically
shuts
off for about three minutes. The warning light will come on and
stay on during that time.
If your brakes overheat, the traction control system will shut off and
the warning light
will come on until your brakes cool down.

Downloaded from www.Manualslib.com manuals search engine ‘f the “TRACTION OFF” warning light comes on and stays on for an
:&ended
period of time, your vehicle needs service.
A CAUTION:
If you let your tires spin at high speed when the “TRACTION
OFF” warning light is on, they can explode and you or others
could be injured. And, spinning your tires with the “TRACTION
OFF’’ warning light on can cause the transaxle to overheat or
can cause other problems. That could cause an engine fire or
other damage. When you’re stuck, spin the wheels as little as
possible. Don’t spin the wheels above
35 mph (55 km/h) as
shown
on the speedometer.

Oil Light
This light tells you if
there could be a
problem with your

oil pressure.
The light goes on when you turn your key to “Run” or
“START” It goes
off once you have started your engine. That’s just a check to be sure the
light works. If it doesn’t, be sure
to have it fixed so it will be there to warn

A CAUTION:
Don’t keep driving if the oil pressure is low. If you do, your
engine can become
so hot that it catches fire. You or others
could be burned. Check your oil
as soon as possible and have
your vehicle serviced.

Press and hold the
Range and Fuel Used
buttons to display the
oil life percentage.
You’ll
see how much oil life you have left, as a percentage. So if you see
“94” for example, that means that the way you’re driving your vehicle,
94%
of your current oil life is still left.
The
“CHANGE OIL SOON” light will come on for a few seconds as a
bulb check when you start your engine. The light will also come on for
20
seconds following engine start-up when either the oil life percentage is
less the
10% or 7,500 miles (12500 km) have been driven. 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 miles
under severe conditions. It all depends on your driving patterns.
(If it
doesn’t,
or if it doesn’t even light up, then something is wrong. You will
need to have it serviced.)
There
are two things the system won’t do: It can’t sense heavy dust in the
places where you drive.
If you drive in a dusty area, you should change
your oil every
3000 miles (5000 km) or 3 months (whichever comes first),
unless the “CHANGE
OIL SOON” light comes on sooner.
It doesn’t check how much oil you have
so you will still have to check for
that.
To check it, see the 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 that, press
and hold the “Range” and “Reset” buttons between
5 and 60 seconds.

Downloaded from www.Manualslib.com manuals search engine Once the buttons are released the “CHANGE OIL SOON” light will
flash 4 times to indicate it has reset to

If the “CHANGE OIL SOON” light comes on and stays on for 5 seconds,
it did not reset. You’ll need to reset the system again.
SPEED SENSITIVE SUSPENSION
(SSS SYSTEM)
The Speed Sensitive Suspension System (SSS) automatically controls the
firmness of your Cadillac’s ride. The vehicle is controlled by an actuator
in each of the four struts to increase ride firmness depending on vehicle
speed and other driving conditions. There are three dampening modes:
COMFORT, NORMAL, and
FIRM. As the vehicle speed increases, the
firmness of the suspension increases. The system is in COMFORT for
speeds less than
28 mph, NORMAL for speeds between 28 and 65 mph,
and FIRM for speeds greater than
65 mph. The system also stiffens
damping during hard acceleration, braking and cornering ,for increased
control.
The SSS controller is a computer 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
“SERVICE
SSS” light will come on and stay on until the problem is
corrected.
If this light should appear, have your vehicle serviced at your
earliest convenience.
SPEED SENSITm STEERING
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 and enhanced vehicle stability.

Downloaded from www.Manualslib.com manuals search engine TRACTION CONTROL (OPTION)
If you have this feature, this brake only Traction Control complements
your anti-lock braking system.
Traction Control regulates tire spin during low-speed acceleration and
steady driving.
The Traction Control Brake-Only System uses the same wheel speed
sensors used by your Anti-Lock Brake System
(ABS). When wheel slip is
detected by the wheel sensors, the electronic control module sends a
signal to the brake pressure modulator to apply pressure pulses to the
brakes. Traction is then maximized and your vehicle is enabled to
accelerate or continue driving with a controlled amount of tire slip. This
low-speed system controls tire slippage and is fully functional until you
reach
a speed of 24 mph and then the traction control is gradually phased
out as your vehicle reaches
30 mph. To keep you informed of changing
road conditions the “TRACTION
ACTIVE” telltale light will illuminate
when the system
is activated.
-
Because this is a brake only Traction Control system, it is designed to
protect your vehicles powertrain components. The system
will
temporarily by disabled should the brakes or transaxle reach excessively
high temperatures and prolonged use
of traction control. The
“TRACTION
OFF” telltale light in the instrument panel informs you
when this system is not in operation.
ELECTRONIC LEVEL CONTROL
This keeps your vehicle level.
The ignition does not have to be
“ON” for the level control to work. 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.

To immediately switch from tape to radio, press the ST-PL button and the
radio will resume playing the station that was tuned in when you inserted
a tape. Pressing
ST-PL again will allow the tape to resume where it
stopped.
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.
Care of Your Compact Discs
Handle discs carefully. Store them in their original cases or other
protective cases and away from direct sunlight and dust.
If the surface of
a disc is soiled, dampen a clean, soft cloth in a mild, neutral detergent
solution and clean it, wiping from the center to the edge.
