Adaptive speed control

On vehicles for certain markets, an adaptive speed control system is installed as an option. In addition to the normal vehicle speed control functions, this system enables a preset distance to be maintained behind a moving vehicle immediately ahead, without driver intervention.

Automatic switch off - vehicles with adaptive speed control 

The adaptive speed control will disengage, but not clear the memory when:

• the CANCEL button is activated.
• the brake pedal is applied.
• the vehicle speed falls below 26Km/h (16mph).
• neutral, park or reverse gear positions are selected.
• traction control is activated.

The adaptive speed control will disengage, and clear the memory when:

• the ignition switch is set to position '0'.

• maximum vehicle speed is reached.
• the parkbrake is applied.
• a fault occurs in the adaptive speed control system.

Forward alert 

The forward alert system is switched on and off by the forward alert switch. The forward alert system additionally provides warnings while the adaptive speed control is not activated.

The speed control module incorporates a radar sensor and yaw rate sensor to provide system control functions.

Adaptive speed control failure 

If a fault occurs during any adaptive speed control operation the adaptive speed control system will be deactivated and will remain in this state until the fault is rectified. The message center will display 'CRUISE NOT AVAILABLE'.
