The ICC cannot be enabled under approx. 30 kph or 20 mph, this is a common safety limit for cruise control systems. The distance can be set up to 50 m.
The system works like a dream, it is so effective that you tend to forget about it and find yourselves cruising blissfully behind a slow car at a ridiculous speed, but as soon as you pull out to overtake, the Q30 kicks down and accelerates.
We’ve been able to verify that the ICC is capable of adjusting in permanence to the traffic flow speed down to nearly standstill.
We faulted it once, as we were following a vehicle with a rack of bicycles at the back.
