Kustjag...if you can find a suitable all season tire, a tire store may swap you no charge for the more expensive performance tires.

As for DSC DTC, is there a sequence of button pushes that deactivated all of these so you can have fun in an empty snowy parking lot? And, when you tap the electronic parking brake at speed, does it stay on, or just activate rear brakes while pushed in like the Volvo electronic e-brake?
