Cruise Control: Description and Operation

SPEED CONTROL

The vehicle speed control system consists of the following components:
- Speed control deactivator switch
- Powertrain control module (PCM)
- Speed control switches

The speed control system is controlled by the PCM. The speed control system is designed to maintain a selected vehicle speed between 48 and 200 km/h (30 and 124 mph). The speed control system is controlled by the steering wheel mounted switches (ON, OFF, SET/ACCEL, COAST, RESUME) and the brake pedal switches (stoplamp and speed control deactivator switches). The steering wheel mounted switches are hardwired to the PCM.

The speed control functions include:
- turning on the speed control system.
- setting and maintaining the desired vehicle speed.
- accelerating the vehicle to a higher speed.
- decelerating to a lower speed.
- tapping-up/tapping-down the vehicle speed.
- deactivating the vehicle speed control system.
- resuming the prior vehicle speed.
- turning off the vehicle speed control system.
