Front sensors should have a button in front of the gearstick to turn them on, or they will come on when you put it in reverse, your dealer should have told you this. If you need anything at the moment your dealer will go out of their way to help you as they need a good result when you get the csq phone call from the brand. And your car should have a NAV dvd, but half the time they are not given out as they forget to order them and just load the maps onto hd from a dvd they have around. Updates are not part of a service, make sure you ask for them to be done at service time.
