Cruise Control: Description and Operation

The speed control system is composed of On-Off, Set-Accelerate, Coast, Resume (if equipped) switches. The system includes vacuum hoses, servo (throttle actuator) assembly, speed sensor, check valve assembly, and depending on model, a clutch switch and stop light switch.
To operate speed control system, the engine must be running and vehicle speed must exceed 30 mph. When the On-Off switch is actuated, the system is ready to accept a set speed signal. When vehicle speed stabilizes (exceeds 30 mph), and the On switch is engaged, the operator may depress or release the Set-Accelerate button. This speed will be maintained until a new speed has been set, brake pedal has been depressed, or the system is turned off.
