Just bought 2012 Titanium

[MBMondeo]

Hi all,

First post - so let me know if I'm doing anything wrong!
I just bought a 2012 Petrol Titanium Sedan in Panther Black with the Sports Executive Pack. The car's got 118,000 kms as the previous owner used it to go from Perth to Port Hedland and back regularly (don't know why she didn't get the diesel)
For a 2012 car the condition is absolutely crap. Like really, really bad. Wasn't taken care of at all. But, I got it for $6500 so that was expected.
I'm hoping to bring it back up to a good condition, especially the paint which needs some serious restoration.
I've had the car a week now and been using all the toys, but I suspect the Adaptive Cruise Control isn't working. Either that or I'm doing something wrong trying to use it...
Its showing up with the bars that you can adjust for distance, but it won't recognise any cars in front at all - no matter how close, what speed etc. tried everything.
If anyone has any knowledge about the system and why it might be playing up - I'd love any help I can get
Oh also the previous owner didn't ever use it (didn't even know it had it) - she only bought the SE pack for the sunroof.

Thanks!!
