Cadillac 1967 VVI Data Book page 154

The Cadillac Rear Window De-Fogger is optional at extra cost
on all models except the convertible and Fleetwood Seventy-
Five sedan and limousine. In operation, the De-Fogger dis-
tributes fan-blown air across the rear window to help clear fog
or steam for better visibility in humid weather. During winter
driving conditions, it helps prevent accumulation of snow or
ice on the rear window glass.
The De-Fogger is controlled by a switch located under the
top edge of the instrument panel cover on the lfeft side. For
"HIGH" fan speed, move switch to the right. For "LOW"
speed, move it to the left. The De-Fogger is "OFF" when the
switch is in center position.
Tilt and telescope steering wheel
The Tilt and Telescope Steering Wheel (optional at extra cost)
permits two separate adjustments of the wheel position for
greater comfort, convenience and driving ease. The steering
wheel can be tilted to any one of six different positions, and
can be moved closer to or farther from the driver over a three-
inch range of adjustment. This permits individual selection of
the most natural and comfortable position for all driving con-
ditions. Also, on long trips, the steering wheel position can be
changed to minimize tension and fatigue. The adjustments are
simple, and independent of each other.
The tilt adjustment is achieved by lifting upward on the small
lever located on the left side of the steering column below the
turn signal lever. The steering wheel can then be tilted to the
desired angle and locked in place by releasing the lever. Mov-
ing the locking lever located on top of the steering column
above the steering wheel cover to the left permits telescoping;
moving the lever to the right locks the wheel. Both the tilt and
telescope mechanisms can be changed while driving, but
should not be attempted in heavy traffic.
These features also permit maximum ease in entering and
leaving the car. The wheel is spring-loaded, so that lifting
upward on the small lever automatically raises the wheel to a
higher position. Additional clearance can be obtained by un-
locking the steering wheel and moving it all the way in.
