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 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.
