5) Cruise Control Switch
A25-626
Fig. 15-260
1.
Main switch
This is a push-button switch located
on the steering column and is the main
power switch of the cruise control.
When the cruise button is depressed,
the green pilot'lamp above the button
illuminates and an electric current
flows in the cruise control unit.
2. Sub-switch (Set lever)
Pushing the tip of the sub-switch knob
allows the set signal to be entered in
the cruise control unit. The resume
signal and coasting signal are entered,
respectively, by turning the knob in
the forward and backward directions
of the car.
6) Cancel Switch
1. Stop & brake switch
The stop switch and brake switch are
fitted to the brake pedal. The stop
switch functions as an ordinary stop
light switch. When the brake pedal is
depressed, the stop switch is turned on
and the brake switch is turned off.
These two kinds of signals will cancel
the function of the cruise control if
the pedal is depressed when driving
with the cruise control in operation.
However, the pre-set car speed will
remain in the memory of the cruise
control unit.
2. Clutch switch
(MT vehicle only)
The clutch switch is fitted to the
pedal bracket. When the clutch pedal
is depressed, the clutch switch is turn-
ed off and the operation of the cruise
control is canceled. However, the pre-
set car speed will remain in the
memory of the cruise control unit.
3. Inhibitor switch
(AT vehicle only)
The inhibitor switch is attached to the
automatic transmission select lever.
When the select lever is shifted to the
"N" range, the switch turns on to
cancel the operation of the cruise
control. However, the pre-set car speed
will remain in the memory of the
cruise control unit.

When the cruise control operates, the
actuator pulls the lever
CV
through the
cable connecting the actuator to the
link ASSY. This movement causes the
lever
00
to pull the stopper
CD
of the
cable connecting the accelerator pedal
to the carburetor. Thus the carburetor
is controlled without depressing the
accelerator pedal.
Further, if the accelerator pedal is
depressed in this state, the cable con·
necting the accelerator pedal to the
carburetor is pulled, so that the car-
buretor throttle lever can be operated
regardless of the movement of the
lever
00
caused by the actuator.
