Cruise Control


All models covered herein were available with an optional speed control system. This system automatically controls the speed of the vehicle when cruising at a stable highway speed. The speed control system consists of the following:

Speed control amplifier/servo assembly
Speed control cable
Vehicle Speed Sensor (VSS)
Speed control actuator switch
Stop light switch
Deactivator switch

The speed control system operates independently of engine vacuum and, therefore, does not utilize any vacuum lines.

The speed control amplifier integrates the system electronics, thereby eliminating any other electronic control modules in the vehicle. The amplifier controls the vehicle's speed via a cable attached to the throttle body lever.

The speed control actuator switch assembly is mounted on the steering wheel and allows the driver to control the system's operation. The switch assembly contains five control buttons for system functioning, namely: ON, OFF, RESUME, SET ACCEL, COAST.

The system will continue to control the vehicle's speed until the OFF button is used, or the brake pedal or clutch pedal (manual transmissions only) is depressed.
