The
PENALTY OF LEADERSHIP

Henry M. Leland,
founder
of
Cadillac,stands
beside the 1905
“Osceola” which
was built to
evaluate the
feasibility
of a
closed bodied car.

Few automobiles are fortunate enough to have the rich heritage
that
is Cadillac.Thename Cadillac is appropriatelythat of
Antoine ’de La Mothe’ Cadillac, the French militqy commander
who founded. the city
of Detroit in. 1701. What better name for
the oldatautomobile manufacturer in Detroit.
Henry M. Leland, known as themaster of precision,commonplaceasstandardizedparts aretoday, in 1908
initiatedhisprecisionmanufacturingtechniquesatthepartswere stillindividuallyhand fittedboth in
founding of Cadillac
in 1902. His exactingstandardsproductionandservice.
prompted the motto
by which Cadillac has been guided
over
the years - “Craftsmanship A Creed - Accuracy
A Law.”
The introduction
of the-firstfour cylinder engine in 1905
led the industry and enabled Cadillacs to travel at speeds
up to
50 mph.
For attention to quality and innovation, the Royal
Automobile Club
of England awarded the prestigious
Dewar Trophy to Cadillac twice. .. first in 1908 for
achieving perfect interchangeabilityof parts and again
for introducing the electric self starter, electric lighting
and ignition system on
1912 models. Cadillacis the
only American manufacturerto win this honor and
the only manufacturerin the world to win it twice. As

Standardization opened the eyesof the industrial world
and was the cornerstone of modern
assembly line
production. From this achievement evolved the
reference to Cadillac as “Standardof
the World.”
In
1909 Cadillac was purchased by the then new
General Motors Corporation.
Convenience, cleanliness and all-weather comfort were
greatly enhanced
in 1910 when Cadillac became the first
manufacturer to offer closed bodies as standard equipment.
‘‘The Penalty of Leadership” first appeared
in the
January
2, 19 15 issue of The Saturday Evening Post as an
expression of the Cadillac commitment to leadership,
quality and innovation. It is widely regarded as one of the
b

fmest documents ever written. It was published following
the introduction of the first production
VS engine,
which was standard in
all Cadillacs beginning with the
1915 model.
Many Cadillac "firsts" have followed over the years,
including the synchro-mech clashless transmission, a
nationwide comprehensive service policy, security plate
glass, chrome plating and thefirst car to be designed by
a stylist (1927 LaSallelHarleyEarl).The
'30s witnessed
production of the powerful, smooth and quiet V12 and
V16 engines. The crisp,contemporary linesof the 1938
60 Special seriesushered in a newera in styling.
VI 6 Engine
During World War 11, shortly after Pearl Harbor,
Cadillac discontinued car productionfor the firsttime
since 1902 in order to constructlight tanks, combat
vehicles and internal
parts for Allison V17 10 engines.
Two Cadillac
V8 engines and Hydra-Matic
transmissions were used in eachMSAI and M24 tanks.

Thereare, tobe sure,many waysto describethe
superlative motor car pictured. “Beauty,”
“majesty,” “brilliance”
- all apply, in their
fullest meaning, to this new Cadillac.And yet,
from this wonderful vocabulary,wehave
selected“elegance”as the word that most fully
characterizes the Cadillac of
1960. The car’s
beautiful,clean-linedstyling
is certainlyelegant
beyond compare. Its new interior luxury
providesafeelingof elegancethatcanbe sensed
nowhere else in the world of motor cars. And
even itsnew performance

(If Equipped)
TheLUMBAR controlis
located on the outboardside
of each front seat.It
provides additional support
to your lower back andit
works independentlyof the
other seat controls. Use the
power seatcontrol firstto
get the proper position.
Then proceed with the
lumbar adjustment.
To reshape the lower seatback, move the LUMBAR
switch forwardto increase support and rearwardto
decrease support. Move the LUMBAR switch sideto
side to raise or lower the support mechanismto suit
your preference.
Keep in mindthat as your seating position changes,as it
may during long trips,
so shouldthe position of your
lumbar support. Adjust theseat as needed.
If you have the optional personalization package,the
power lumbar control can be programmedfor memory
recall. For more information, see “Programmable,
Memory and Personalization Features” inthe Index.

Heated Front Seat (Option)
The control is located on the outboard side of each front
seat. Move the
SEAT HEAT control to either LO or HI
to turn on the heating elements in the seat.The
LO

A telltale light in
the control remindsyou that the heating system is in use.
The heated seats can only be used when the ignitionis
turned on.
Reclining Front Seatbacks
Press the recliner control forward or rearward to adjust
the seatback.
1-4

But don’t havea seatback reclinedif your vehicle
is moving.
Sitting in a reclined positionwhen your vehicle is
in motion can be dangerous. Evenif you buckle
up, your safety belts can’t dotheirjob when
you’re reclined like this.
The shoulder belt can’t do itsjob because it
won’t beagainst yourbody. Instead, itwill be in
frontof you. In a crashyou could go intoit,
receiving neckor other injuries.
Thelapbelt can’t doitsjob either. In
a crashthe
belt could
go up over your abdomen. The belt
forces would be there, notatyour pelvic bones.
~ This could cause seriousinternalinjuries.
~ For proper protection when the vehicle is in
motion, have the seatback upright. Then sit well
back
in the seat and wear your safety belt properly.
Head Restraints
Slidethe head restraint up or down so that the topof the
restraint
is closest to the top of your ears. This position
reduces the chance
of a neck injury in a crash.
