For the 1948 model, Cadillac
introduced the legendary
tail fin
which set the trend in automotive
styling for nearly two decades. This
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
sentinel 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.
introduced in
1953, was redesigned for 1967 as the
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.

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

Your vehicle has strategicaly placed clectronic sensors, that feed
information to the vehicle’s computer systems. Your vehicle can control
the ventilation, heating, and air conditioning automatically year round.
The outside temperature, inside temperature setting, fan speeds, and the
ECC selection are displayed on a digital screen.
OFF: Nothing is on, but air will flow through your vehicle if you’re
moving. The system
will try to keep the air at the selected temperature,
but it
might not be able to maintain it if it’s hot, or cold, outside.
“OUTSIDE’’ Temperature: The outside temperature is always displayed
when your vehicle is running. You can change
it from Celsius to
Fahrenheit by pushing the ENG/MET(English/Metric) button.

come out the A/C outlets
to maintain comfort.
Electronic Climate Control Features
A/C Purge
If your vehicle is sitting out on a hot day and you have it set on AUTO,
the air will first flow out the floor air ducts for a few seconds. That is
normal. This is to expel hot air in the air ducts. As the air is cooled, the
flow will move through the A/C outlets.
Cold Weather Purge
On cold days when your system is first turned on, at any setting other
than Defroster, DEFOG
or OFF a small amount of air will flow through
the defroster duct preventing your windshield from fogging.
Automatic Defog
When using your wipers or rear window defogger for several minutes, the
system senses that
a humid condition exists. When this happens air flow
will be directed to the windshield and floor ducts to keep your side glass
and windshield clear.
Manually Recirculate Inside Air
There may be times, when you don't want air from the outside. To
recirculate the air from the inside only, just set the temperature to 60°F
(16OC) and adjust your fan speed.
DEFOG
Push this button to divide the air between the Windshield and the heater
ducts. This is useful
when fog appears on the windshield or side glass due
to a sudden
rain.
