The Speed Control system offers the driver relaxed vehicle cruising by enabling a pre-set constant vehicle speed to be maintained without driver operation of the accelerator pedal.

Scheme 2

The speed control switch provides for driver increase (SET +) or decrease (-) of set vehicle speed, suspension of system operation with set speed memorized (CANCEL) and resumption of operation at memorized vehicle speed (RESUME). The vehicle speed control system will not operate below 26km/h (16mph).

The set vehicle speed can be increased or decreased in 2km/h (1mph) increments by briefly pressing the (SET +) or (-) control button. Alternatively, the (SET +) or (-) button can be pressed and held until the required vehicle speed is reached.

Automatic switch off - vehicles without adaptive speed control

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

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

The speed control will disengage, and clear the memory when

  1. the ignition switch is set to position '0'.
  1. maximum vehicle speed is reached.
  2. the parkbrake is applied.
  3. a fault occurs in the adaptive speed control system.

Speed control failure - vehicles without adaptive speed control

If a fault occurs during any speed control operation the 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'.

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.

  3. the vehicle speed falls below 26Km/h (16mph).
  4. neutral, park or reverse gear positions are selected.
  5. traction control is activated.

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

  1. the ignition switch is set to position '0'.
  1. maximum vehicle speed is reached.
  2. the parkbrake is applied.
  3. 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.

Scheme 4

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'.
