was followed
by the 1949 model with
the two door hardtop Coupe DeVille
and the modern overhead valve,
high compression
V8 engine.
Engineering innovations, con-
veniences and styling dominated the
'50s and '60s. Cruise control, auto-
matic climate control,
tilt and
telescoping steering wheels, twilight
sentine1 and four door hard tops all
debuted in these years. In 1957 the
Eldorado Brougham featured
ad-
vances such as air suspension, mem-
ory seat, automatic electric door
locks, transistor radio, a brushed stainless steel roof and
low profile
tires.

first front wheel drive personal lux-
ury car. The
472 cu. in. V8 engine
used in
all Cadillacs in 1968 and
1969 was enlarged to
500 cu. in. for
all 1970 Eldorados.
An Air Cushion Restraint Sys-
tem (airbag) was available for
1974,
1975 and 1976 Cadillacs.
Analog Electronic Fuel Injec-
tion was available, on 1975 Cadillacs
and
was standard on the new inter-
national size 1976 Seville. In 1978,
the Trip Computer option incor-
porated an on-board microprocessor.

into the
'90s as Cadillac became the
first automobile manufacturer to be
awarded the prestigious Malcolm
Baldrige National Quality Award.
The 1992 Seville
STS was the
first car ever to win all three major
automotive awards: Car of the Year,
Motor Trend; Ten Best List, Car
&
Driver; Car of the Year, Automobile
Magazine.
A 1993 Cadillac Allantk in stock
technical configuration, was selected
as the pace car for the
76th Indianap-
olis
500. The demanding pace car
performance and handling require- ments were met because of such
advances as the Northstar system.
The system includes
the 32 valve,
dual overhead camshaft, Northstar

cally controlled automatic transaxle,
road sensing suspension, speed sen-
sitive steering, antilock brakes and

Cadillac has been a leader in quality
and technical innovation.

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 increased to provide a manual like steering
feel for maximum control and enhanced vehicle stability.
Road Sensing Suspension
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 CONTROL’ message will display on the Driver
Information Center. If this message should appear, have your vehicle
serviced at your Cadillac dealer at your earliest convenience.

the vehicle must be towed on the front wheels, don’t go more than 35
mph (56 km/h) or farther than 25 miles (40 km) or your transaxle will be
damaged. If these limits must be exceeded, then the front wheels have to
be supported
on a dolly.
Do not attach winch cables or ‘3” hooks to suspension
components when using car carrier equipment. Always use
T-hooks inserted in the T-hook slots.

Even things beyond your control such as weather conditions affect your
fuel economy. Driving up steep hills, in rain or snow, and into a strong
wind will lower fuel economy. In the lower left corner
of the fuel
economy window sticker from your vehicle is the range of city and
highway fuel economy you can expect to get from your Cadillac. If you
are doing everything to raise your fuel economy, but are still not within
this range, your vehicle may need service. Collect as much information
about your fuel economy as you can find, (miles driven, gallon's of fuel
used, etc.) and provide it your dealership for their review and assistance.

by the combination
of 4 speed overdrive gearing, a torque converter
clutch, with a
3.71:l final drive ratio on the STS and a viscous converter
clutch with a
3.11:l final drive ratio on the Seville SLS.
Front Suspension
Your fully independent front suspension is a combination strut and spring
design. The frame is isolated from the body with
six rubber mounts.
Rubber bushings are used at the lower control arm pivots. The upper end
of the strut is isolated by a rubber mount which contains a bearing to
allow for wheel turning. The Road Sensing Suspension automatically
controls the damping rate of the struts.
The lower end of the steering knuckle pivots on a ball joint riveted to the
control arm. The ball joint
is connected to the steering knuckle with a
castellated nut and cotter pin.
