Cruise Control: Description and Operation
For the Speed Control System to operate, the engine must be running and the vehicle speed must be greater than 30 mph. The Speed Control System is activated by pressing the ON switch of the Speed Control Switch.
SET/ACCEL or COAST
Pressing and releasing the SET/ACCEL or COAST sends a signal of the present speed: this speed becomes the set speed. If the vehicle speed changes, the vehicle speed signal received by the Speed Control Module no longer matches the set speed stored in memory. This difference causes the Speed Control Module to generate signals to the Speed Control Servo to either open or close the throttle until the speed signals match.
SET/ACCEL
The vehicle's speed increases while SET/ACCEL is depressed. Releasing SET/ACCEL gives the system a new set speed to maintain. Vehicle speed may also be increased by depressing the accelerator until the higher speed is reached, then pressing and releasing SET/ACCEL.
COAST
Pressing and holding COAST slows the vehicle down. Releasing COAST gives the system a new set speed to maintain.
OFF
The system is deactivated by pressing the OFF switch of the Speed Control Switch. The system is also turned off when the brake pedal is depressed or when the Ignition Switch is turned to the OFF position. In vehicles with manual transaxles, the Clutch Switch opens when the clutch pedal is depressed and turns off the system.
RESUME
When the system has been deactivated by depressing the brake or clutch pedal, the last speed may be resumed by pressing RESUME. This feature will not work if OFF has been depressed or if the car speed is below 30 mph.
