some Outback models eg. 2012 are NOT good off road in slippery conditions because the car’s centre diff is open, and it relies only on electronic traction control (ETC) to move in these conditions but as soon as the car slips or slides even a little, stability control kicks in and kills momentum. The problem is that there is no way to have traction on and stability control off. This has been resolved in later 2015 onward models with X-mode.
2) X-mode is activated by a button on the center console, X-Mode is supposed to make your wagon’s ABS and stability control work together to maximize low speed traction. The CVT is put into a low gear ratio to give it some grunt, and the AWD system is locked into putting power to every wheel, not just the tyres with least resistance.
