1982 Mercury LN7 Automatic TransFACTORY OEM SERVICE PROCEDURE

Cruise Control Systems: Operation

This system is operational at speeds above 30 MPH. When the "ON-OFF" switch is set to the "ON" position and the driver depresses and releases the "SET - ACC" button, the vehicle speed will be maintained until a new speed is set by the driver, the brake or clutch pedal is depressed, or until the system is turned off. When the system has been de-activated by depressing brake or clutch pedal, the driver can re-establish set speed by pressing and releasing the "RESUME" switch.
