Does anyone know how to get the Hill Start Assist to work correctly, I think this the the correct name.

Manual says if you press hard on the footbrake and then take off electronic handbrake you will get a couple of seconds held on the brake before if releases.

Obviously we have not had the Insignia long but I cant get this to work at all. Keeps creaping up or down the hill - really worrying!!!

Any tips!

Cheers
