In the car set-up (press car button on the radio, then press the cog icon on the touchscreen and it’s in there, maybe under something called “assistance systems” or “driver aids” – something like that. There will be a tick box for front assist) you can set front assist active, it can work independently of the ACC (Active Cruise Control), so you can have it on all the time with or without cruise control being used.
Not sure how well mine works to be honest – sometimes it does not want to detect something that should be well within range of giving you the first warning symbol (2 cars with a “!” in between). You can be quite close to the car in front on the flat or going downhill and no detection is made, yet you start going uphill at the same distance or less and the symbol appears. It is as if the sensor is looking over the top of the car in front when going downhill and not seeing it. Something I will have set but not rely upon. Not sure how affected by frosting up or getting dirty the sensor is when we are now into mucky winter driving.
