Scientific Soundproofing
The quietness of Cadillac interiors, a matter of pride and pleasure for
Cadillac owners, is achieved through selected soundproofing. There is a
molded one-piece sound barrier between engine and passenger compart-
ments and sound deadening material at designated areas to absorb noise of
thrown gravel. Added quietness is assured by insulation in rear quarter
panels to reduce tire noise and rubber door seals which greatly reduce
wind noise. A highly efficient rubber compound sound barrier is used at
each side of the cowl. A thicker sound barrier insulates front compartment
floor. Rear compartments have two layers of jute topped by deep carpeting.
There is a layer of felt deadener and a layer of tufiex insulation between
the steel top and headlining of Calais, De Ville, Fleetwood Eldorado,
Sixty Special and Brougham models. The underside of the hood is insulated
by 1W thick fiberglass.
Ignition Switch Helps Protect Battery
The Cadillac ignition switch provides a stop which requires pressing the
key inward slightly before turning it to
ACCESSOBY
position. This reduces
the likelihood that the key will be inadvertently turned past OFF to
ACCESSORY
position and thus reduces the possibility of running down
the battery.
