Principle of operation

The adaptive cruise control system is designed to help you maintain a gap from the vehicle ahead or a set road speed if there is no slower vehicle ahead. The system is intended to provide enhanced operation of the vehicle when following other vehicles which are in the same lane and travelling in the same direction.

Adaptive cruise control is not a collision warning or avoidance system. The separate forward alert function provides a collision warning and mitigation feature. See Forward alert function. You must intervene if the system does not detect a vehicle in front.

Adaptive cruise control cannot cover all traffic, weather and road conditions.

When driving you are responsible for maintaining the correct distance and speed, even when adaptive cruise control is used. You must always pay attention to the traffic conditions and intervene when adaptive cruise control is not maintaining a suitable speed or suitable distance.

The adaptive cruise control does not brake for slow or stationary vehicles.

When ACC is activated, you may hear some unusual sounds during automatic braking. This is normal and caused by the automatic braking system.

The adaptive cruise control system is based on the use of a radar sensor which projects a beam directly forward of the vehicle. This beam will detect any vehicle ahead within the system's range.

The radar sensor is mounted behind the front grille, immediately to the right of the Ford badge (when viewed from the front of the vehicle).

When using ACC, follow the strict guidelines below:
Х Only use adaptive cruise control when conditions are favourable, for example on motorways and main roads with steady free flowing traffic.

Х Do not use in poor visibility, specifically fog, heavy rain, spray or snow.

Х Do not use on icy or slippery roads.

Х It is your responsibility to stay alert, drive safely and be in control of the vehicle at all times.

Х Keep the front of the vehicle free from dirt, metal badges or objects, including vehicle front protectors and additional lights which may prevent the sensor from operating.

Х Do not use ACC when entering or leaving a motorway.

The radar sensor has a limited field of vision. In some situations it may detect a vehicle other than the one expected or not detect any vehicle at all.

Detection beam issues
Detection beam issues

Detection issues can occur: Х When driving on a different line to the vehicle in front (A).

Х With vehicles that edge into your lane that can only be detected once they have moved fully into your lane (B).

Motorcycles may be detected late, or not at all.

Х There may be issues with the detection of vehicles in front when going into and coming out of a bend (C). The detection beam will not follow sharp curves in the road.

In these cases ACC may brake late or unexpectedly. The driver should stay alert and intervene if necessary.

Automatic braking with ACC

Adaptive cruise control will automatically brake for you, if required to maintain the set gap between your vehicle and the one detected in front. This braking capacity is limited to approximately 30% of the total manual braking capacity to ensure smooth and comfortable cruising. If the car needs to brake more heavily than this, and you do not intervene by braking manually, an alarm will sound and a warning symbol will be displayed in the cluster.

You must take immediate action once alerted, as the ACC braking will not be sufficient to keep a safe distance to the vehicle in front.
