Driver Assistance Package

There are a few pre-reqs to that function working (based on my MY20 model in Aus anyway). Obviously you need to be in cruise control mode, and lane change is only active above something like 80kph. It's also dependent upon the car clearly seeing the lane markings (the little green lines in the dash) and functioning rear radar sensors. It's also disabled (as is lane keep) if you have a tow bar in-use.

When our car first arrived, one of the radar sensors was not mounted correctly, so it was pointed in the wrong place, and the feature basically never worked (nor lane keep assist) until they fixed the mount.

@tGs Wraith . Thank you for your reply. I'm generally well above 80kph (49.7 MPH here in California) when I try using the Lane Change Assist function. And Yes I have the cruise control ON, but I will have to verify if the little green lines in the dash, as you call them, are lighted. Also I tried it several times on freeways with good white line markings. I do have the tow package but I'm not using it. What I found strange is the Lane Change Assist worked fine for several months, and then just stoped working. I will take the car to the dealer and ask them to test it. It's possible that one of the radar sensor is out of calibration. I will post a note after my dealer visit.
