What tire pressure mode do you use for every day use? We usually drive it with 1 or 2 people max, so I would assume that the light mode would be sufficient. What are the pros and cons of each mode? We are going for a long trip in a couple of weeks, again just me and my wife with some luggage, pretty much all highway driving. The dealer set the car for normal driving mode, but .... they also didn't know that external mirrors should fold....
