1) Theres a little switch in the glovebox for the power boot, check it out and see if it makes a difference. Also, try the spare fob to see if that works. If not, may need taking to the dealer.
2) Not paid much notice to it but mine is semi-soft open. Its not too fast and not too slow. Best thing to do is pop into the dealers and check their demo as they all use the same interior bits.
3) You'll need to activate the rear wiper and turn it off when it gets halfway and is completely vertical. You can buy refills or just change the whole blade, its a standard hook type fitting.
4) Im not too sure on the exact specifications of the SEL Premier but if it has Adaptive cruise control, it should have the PCS too. To check if you have adaptive cruise control, look for the button on the steering wheel with a wave coming out of the front. The PCS switch off button should be close to the steering wheel, either where the buttons are to the right of the steering wheel, or, if equipped, where the TPMS reset button is which is further down, near the bonnet opening lever
5) That thud would need checking by a mechanic - sounds like a suspension issue.
