My dealer guy said to drive it as normal - he said the worst thing you could do to it was drive it like an old lady. He says to "drive it out in the gears" (danish expression, don't know how to translate it proper).Try to vary your speed a bit. Don't just keep the revs constant for extended periods of time - he says that if people try to "go easy on it" by, say, staying in 3rd gear when doing a turn the car would like it more if you downshifted and gave it some gas.
I recently had a really nice trip from Denmark to France and back - I actually hit a top speed of 175 kph (108 mph) at one point - the car actually felt like it could have gone faster had I had the inclination to.
Real nice trip btw. Ppl gawked and stared all the way through Germany and back - it seems they are not even commonplace in Germany yet!
At one point we DID spot an up! - - but then I saw a VW dealership 100 meters down the road, so I'm assuming that someone was probably out test driving that up!
