The cruise control system maintains vehicle speed with a vacuum-actuated servo motor installed in the engine compartment and connected by a cable to the throttle valve. The system consists of a servomotor, clutch, brake, switches, relays and vacuum hoses.
Repair and adjustment of the cruise control system should be carried out on special equipment at a service station, except for breakdowns that you can fix yourself: broken vacuum hoses, fuse, broken wires, etc.
