Cruise Control: Description and Operation

SPEED CONTROL

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

The speed control system is controlled by the powertrain control module (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:
- turn on the speed control system
- set and maintain the desired vehicle speed
- accelerate the vehicle to a higher speed
- decelerate to a lower speed
- tap-up/tap-down the vehicle speed
- resume the prior vehicle speed
- turn off the vehicle speed control system
