Questions about the first Volvo

Hello moose community, I’ve had my first Volvo, XC60 MY2016 for 14 days and have my questions. The pairing with the Iphone 6 worked well but the connection to the Internet doesn’t work. I made the following Internet connection via Bluetooth then selected the Iphone, he then searches, but the Bluetooth remains grey. Must be set somewhere else. Have the Sensus HP without VOC The second question would be, where is the difference between color and contrast modu s in the speedometer unit. At first glance there is no big difference to be seen or ? and thirdly the question with the servo support light – is now light support or light power steering meant? and the last question for the moment, can one program the seat adjustment e.g. the 1 on one key and the 2 on the other key? Thank you already for the help, because the BA is not very helpful
