GENERAL DESCRIPTION
Cruise Control is an easy-to-use, driver-operated speed
control system. It may be either factory or dealer installed
on all V-8 engines except
F
and
X
Series.
ENGAGEMENT
Maintain desired speed and depress engagement button
(located in the end of the turn signal lever), then release
button slowly. The cruise system immediately takes over
throttle position control and within engine limitation
maintains this speed regardless of changes in terrain. (The
lowest speed at which the system can be engaged is 30
mph).
DISENGAGEMENT
The system automatically disengages whenever the brake
is depressed. To re-engage, again maintain the desired
speed and push the engagement button.
SPEED ADJUSTMENT
Upward
-
Accelerate to and maintain any desired speed
above 30 mph, depress engagement button fully, then re-
lease slowly.
Downward
-
Release control by pushing in the engage-
ment button. When car decelerates to the newly desired
speed, release the engagement button slowly.
