For the 1948 model, Cadillac
introduced the
7
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
1
stainless steel roof and low profile
tires.
The Eldorado,I 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.

Charge Light
When you turn the key
to “Run,” this light will
come on briefly, to
show that your
alternator and battery
charging systems are
working.
If a light stays on, you need service, and you should take your Cadillac to
the dealer at once.
To save your battery until you get there, turn off all
accessories, and set your Electronic Climate Control system to “OFF.”

COMFORT CONTROLS AND AUDIO SYSTEMS
In this section you'll find out how to operate the comfort control systems
and audio systems offered with your Cadillac.
Be sure to read about the
particular system supplied with your vehicle.
YOUR CADILLAC AIR SYSTEM
This part tells you how to make your Electronic Climate Control work for
you.
Outside Air
Outside air always flows through your Cadillac when the car is moving.
Even
if the car is not moving, you can always get outside air to flow
through by selecting any air choice (except the rear window defogger).
Air Outlets
Here's how to adjust the instrument panel air outlets:
Move the center lever to direct air flow
from side to side.
Move the side lever
down to stop the air flow.

The Electronic Solar Sensor is part of the Electronic Climate Control
System. It is located on top of your instrument panel speaker grill.
The sensor monitors
the sun's solar
radiation by telling the
Electronic Climate Control system what
angle and the intensity
the sun is at. The
Electronic Climate Control then can
automatically make
the necessary
temperature
adjustments.
AUDIO SYSTEMS
Your Dekoa sound system has been designed to operate easily and give
years
of listening pleasure. But you will get the most enjoyment out of it if
you acquaint yourself with it first. Find out what your Delcoa system can
do and how to operate all its controls, to be sure you're getting the most
out
of the advanced engineering that went into it.

Every new Cadillac has a Delco Freedoms battery. You never have to
recommend a Delco Freedoms battery. Get one that has the catalog
number shown on the original battery’s label.

?+hide Storage
If you’re not going to drive your vehicle for 25 days or more, take off the
black, negative
(-) cable from the battery. This will help keep your battery
from running down.
A CAUTION:
Batteries have acid that can burn you and gas that can explode.
You can be badly hurt if you aren’t careful. See LLJump Starting’’
in the Index for tips on working around a battesy without
getting hurt.
Contact your dealer to learn how to prepare your vehicle for longer
storage periods.
Battery Power Loss
- .-
If you lose battery power or the battery is disconnected, your car’s
computer must be programmed. It takes just over 20 minutes
to do it. If
you want to do it yourself, here’s how:
Apply the parking brake.
Make sure the front wheels are straight.
Turn off the Electronic Climate Control.

Your Cadillac’s lamp housings are designed with small vents so moisture
will be removed when the lights are on, or after driving for
a short time.

Downloaded from www.Manualslib.com manuals search engine Treadwear
The treadwear grade is a comparative rating based on the wear rate of
the tire when tested under controlled conditions on a specified
government test course. For example, a tire graded
150 would wear one
and a half
(1 112) times as well on the government course as a tire graded
100. The relative performance of tires depends upon the actual
conditions
of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices and differences
in road characteristics and climate.
Traction - A, B, C
The traction grades, from highest to lowest are: A, B, and C. They
represent the tire’s ability to stop on wet pavement as measured under
controlled conditions on specified government test surfaces
of asphalt
and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire
is based on braking
(straight-ahead) traction tests and does not include cornering (turning)
traction.
Temperature - A, B, C
The temperature grades are A (the highest), B, and C, representing the
tire’s resistance to the generation
of heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure.
The grade C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
Warning:
The temperature grade for this tire is established for a tire that
is properly inflated and not overloaded. Excessive speed, underinflation,
or excessive loading, either separately or in combination, can cause heat
buildup and possible tire failure.
Those grades are molded on the sidewalls
of passenger car tires.
