ACTION, move the control lever between "OFF" and "MAX"
to the position that provides the desired time delay. Maximum
time delay is approximately 90 seconds.

lever clockwise to the "OFF" position. This permits con-
ventional operation of lights with the headlight control knob.
RADIOS
The Cadillac AM, AM-FM and AM-FM Stereo radios (all
optional at extra cost) are fully transistorized. The AM-FM
Stereo radio is available on all model cars except the Fleetwood
Seventy-Five sedan and limousine. The following instructions
on the use of the AM-FM radio and operation of the controls
also apply to the AM-FM Stereo radio. The features that per-
tain exclusively to the AM-FM Stereo radio are explained in
this section beginning on page 31.
The radio is located in the center of the instrument panel.
Two control knobs are located to the left of the radio dial.
Five push buttons are provided below the dial and a selector
bar is provided above the dial.
The left control knob is the "ON," "OFF" and "VOLUME"
control. The ring behind the left knob controls the tone.
Turned to the left, bass tones predominate—turned to the
right, treble tones are accentuated. Balanced tones can be
obtained by centralizing the ring in its detent position.
Pushing in on the right knob raises the antenna; pulling out
lowers the antenna. The ring behind the right knob controls
the operation of the front and rear speakers. Counterclockwise
rotation accentuates the rear speaker. Clockwise movement
accentuates the front speaker. Balanced sound can be obtained
by centralizing the ring.
Manual tuning is accomplished by turning the right control
knob to set the pointer at the desired frequency on the dial.
The five push buttons can be pre-set to favorite stations.
Tune in the desired station nearest the left end of the dial with
the manual tuner knob. Fine tune until best reception is
obtained. Pull the first button straight out, then push the
button all the way in. The first button will now select that
station repeatedly. Continue this process for setting the
remaining buttons on other stations.
