On the MK 3 and 3.5

am i correct that the pre face lift only detects upto 20 MPH and the face lift upto 30 MPH?

 

can this be changed ? i.e. higher ?

You are indeed correct that the Active City Stop system on the Focus MK3 only works below 20 MPH and the Focus MK3.5 Active City Stop system only works below 30 MPH. The Active City Stop system does not work below 3 MPH.

It is not possible to change the speed. The Focus MK3.5 Active Park Assist system is a further developeped, improved version of the original Active Park Assist system that was introduced on the Focus MK3. Both systems are not fully identical.

Be aware that in most Countries the MK3/MK3.5 Active City Stop system was an optional feature on most trim levels. It was not fitted as standard.

thanks for the reply 🙂

my Sister has the "self parking" feature with front rear parking sensors on a 2014 model, does that mean it has enough hardware to enable Active City Stop? (or do they get a posher radar somewhere) if so is it a simple as ticking a box in something like ForScan?

Active Park Assist has nothing to do with Active City Stop.

The Active City Stop system has an infrared laser and 2 infrared receivers that are installed in the large window console behind the windshield.

1 and 2 = Laser and sensors for the Active City Stop system (only present if the car has Active City Stop).
3 = Camera needed for Lane Keeping Aid, Traffic Sign Recognition and Auto high beam (only present if the car has functionality that requires the camera).
4 = Light/rain sensor

The Active City Stop is based on the reflection of the laser. The laser is constantly outputting a pulsed infrared laser beam. The reflection of the pulsed infrared laser beam on any obstacle in front of the car is detected by the sensors every 0,02 seconds. This way the system is able to detect the distance between the car and any stationary or moving object in front of the car. If the distance suddenly becomes smaller or the system suddenly detects a nearby obstacle the system will set up maximum brake force and wait for the driver to react. If the driver does not react (by applying the brakes) the Active City Stop system will apply the brakes automatically and generate a warning message on the instrument cluster display.

thanks for the info, very helpful
