Wow thankyou, I have read the manual but some of the buttons listed do not appear on my UK spec car (I also miss the cup holder!) and have been advised by my local dealer that the airbag on the Passenger side can't be deactivated.

But I have contacted my local Mercedes dealership, to enquire about their car seats ....so I have my fingers crossed that my little boy does become the coolest kid at nursery in his mummies convertible

thankyou again ......
