Downloaded from www.Manualslib.com manuals search engine some warning lights come on briefly when you turn the ignition key just to
let you know they’re working.
If you are familiar with this section, you
should not be alarmed when this happens.
When one
of the warning lights comes on and stays on when you are
driving, check the section that tells you what to do about it. Please follow
the manual’s advice. Waiting to do repairs can be costly
-- and even
dangerous.
So please get to know your warning lights. They’re a big help.
Your vehicle may
also have a driver information system that works along
with the warning lights. See “Driver Information System” in the Index.
Brake System Warning Light
Your Cadillac hydraulic brake system is divided into two parts. If one part
isn’t working, the other part can still work and stop you. For good
braking, though, you need both parts working
well.
If the warning light goes on, there could be a brake problem. Have your
brake system inspected right away.
BRAKE
(0) BRAKE
This light should come
on as you start the
vehicle. If it doesn’t
come
on then, have it
fixed
so it will be ready
to warn you if there’s a
problem.
This light will also come
on when you set your parking brake, and will
stay
on if your parking brake doesn’t release fully. If it stays on after your
parking brake
is fully released, it means you have a brake problem. If the
light comes
on while driving, pull off the road and stop carefully. You may
notice that the pedal is harder
to push. Or, the pedal may go closer to the
floor. It may take longer to stop.
If the light is still on, have the vehicle
towed for service. (See “Towing Your Vehicle” in
the Index.)

km) and 7500 miles (12500

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)

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
