SPEED CONTROLThe speed control system consists of the following components:
- Speed control switches
- Speed control deactivator switch
- Speed control indicator
- Powertrain control module (PCM)

The steering wheel mounted switches are hardwired to the PCM.
The speed control functions include:
- Turning the speed control system on.
- Setting and maintaining the desired vehicle speed.
- Accelerating the vehicle speed.
- Decelerating the vehicle speed.
- Resuming the prior vehicle speed.
- Turning the vehicle speed control system off.
