Description And Operation: Overview: Notes

There are three variants of speed control available; a standard speed control system, an adaptive speed control system and a speed limiter system.

The standard speed control system maintains a set speed selected by the driver until operation is suspended or cancelled by a further input from the driver and is controlled by the Powertrain Control Module (PCM).

The adaptive speed control system includes the same functionality as the standard system, but also has the ability to:

• Automatically reduce vehicle speed, to less than the set speed, in order to maintain a selected time gap behind a slower moving vehicle.
• Automatically accelerate the vehicle back to the set speed, once the way ahead is clear, after reducing the set speed because of a slower moving vehicle.
• Alert the driver when the vehicle comes within a given time gap of a slower moving vehicle (forward alert feature).

The ASL system restricts the vehicle speed to an adjustable preset maximum, and will prevent the vehicle exceeding that speed.
