For the 1948 model, Cadillac
introduced the
e
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.
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.

Driver Information Center Messages
These messages will appear if there is a problem sensed in one of your
vehicle’s systems. Vehicles that are first sold
in Canada or are export
vehicles will have a number after each message. This number helps to
identify that message, which is only displayed in English.
APPLY BRAKE TO SHIFT - 46
This message will appear if your vehicle is in “P” (Park) for about 15 seconds
and the brake
is not depressed. If you do not want this message to appear,
you
can cancel this message by holding the “OFF” and the Blue (cooler)
button on the Electronic Climate
Control panel for about 5 seconds. Hold the
same
two buttons again to have this message displayed again.

This message shows that the electrical charging system is overcharging,
(more than 16 volts).
To avoid being stranded have the electrical system
checked by your Cadillac dealership at your earliest convenience.
You can
reduce the charging overload by using the accessories. Turn on the lights,
radio, set the Climate Control
on “AUTO” and the fan speed on “HI”
and turn the rear window defogger on.
You can monitor battery voltage
on the Driver Information Center by toggling the “INFORMATION’’
button. When the engine is running, the normal range is 11.5 to 15.5
volts.
BATTERY VOLTS LOW - 06
This message will appear when the electrical system is charging less than
10 volts, or
if the battery has been drained. If this message appears
immediately after starting it is possible that the generator can still
recharge the battery.
The battery should recharge after driving a few
miles and the message should go out. If this message appears while
driving or after starting your vehicle and stays on, have
it checked
immediately to determinethe cause of this problem. To help the
generator recharge the battery quickly,
you can reduce the load on the
electrical system by turning
off your accessories. You can monitor battery
voltage on the Driver Information Center by toggling
the
“INFORMXTION” button. The normal range is 11.5 to 15.5 volts.
CHECK BRAKE FLUID - 37
This message is displayed to inform the driver that the brake reservoir
fluid level is low. Check the brake reservoir
level and add as needed.
Have the brake system serviced by a Cadillac technician as soon as
possible. If the brake warning light is on, follow the directions in that
section.

This message will appear for a few seconds when you select a speed to
cruise at.
ENGINE COOLANT HOT - 44
This message will appear when your engine coolant temperature is over
126°C (259OF). To avoid added strain on a hot engine, turn off your
Climate Control system, and stop and allow your vehicle to idle until it
cools down or the message
is removed. If it does not cool down, turn off
your engine and have it serviced before driving it again. Severe engine
damage can result from an overheated engine. See “Engine Overheating”
in the Index.
ENGINE HOT - A/C COMPRESSOR OFF - 16
This message will appear when the Climate Control is in “Auto” or
“Defrost” and the engine coolant is hotter than the normal operating
temperature.
To avoid added strain on a hot engine the air conditioning
compressor is automatically turned
off. When that happens, air
conditioned air is not delivered.
If the coolant temperature returns to
normal, the
A/C operation returns to normal.

this message appears.
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 and enhanced vehicle stability.
Speed Sensitive Suspension
The Speed Sensitive Suspension automatically controls the ride of your
vehicle. The system controls damping forces in the shock absorbers and
struts in response to various speed and road 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 the
Comfort mode, for speeds less than
40 mph (65 km), normal mode for
speeds between 40 mph
(65 km) and’70 mph (110 km/h), and firm for
speeds greater than 70 mph
(1 10 km/h). The system also stiffens damping
during hard acceleration, braking and cornering for increased control.
The Speed Sensing Suspension controller is a computer used to control
and monitor the system. The computer receives inputs from acceleration
and determines optimum mode strut valving
(or suspension stiffness) for
your current operating conditions. The computer also receives feedback

-I
Your vehicle has strategically placed electronic 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.

Downloaded from www.Manualslib.com manuals search engine AUTO
With this setting, the air conditioning compressor cycles when needed to
cool the air and it’s all automatic. In cold weather when the system senses
- the need for heat, the air flow will be directed out the floor ducts. As the
interior temperature approaches the desired setting, the blower speed
will decrease and the air flow could be directed through the defroster and
floor ducts.
To maintain interior comfort, the air flow may move to the air
outlets and floor ducts (Bi-level). On bright sunny days
in cold weather,
the air
flow could even come out the A/C outlets to maintain comfort and
prevent stuffiness.

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. If you start your vehicle with the
fan setting on “HI” it will skip the
A/C Purge.
Cold Weather Purge
-- On cold days when your system is first turned on, in either the AUTO or
ECON setting and the fan setting is not on “HI”, a small amount of air
will flow through the defroster duct while the system is waiting for the
