Hi Pauly,
Thanks for the quick reply.
My vehicle is a 2016 T6 Caravelle Highline and it was supplied as standard with the Side Assist function. it is also called Lane change assist system in the owners manual. It is the system that lights up, in orange, the black panels on the inside face of the door mirrors. I set the Side Assist (as it is called in the MFD section of the instrument cluster) by using the right hand side button on the steering wheel to find Side Assist and then turn it on by pressing the button on the steering wheel. The box next the words Side Assist now has a tick in it and the lights on the mirror function as expected when driving. However, when I turn the ignition off and switch it on again the Side Assist function needs to be re-set. My question is, should this function "latch on" and not require re-setting after every start?
Many thanks
Phil
