Drove last evening in 1st snow with this car, it was a sudden snow squall burst on the interstate causing severe slowing and even thoughts of pulling over considering the snow amount being dumped in a very short period of time. Car ran flawless and my thoughts went to am I in 2 or all time 4-wheel drive, scrolling through the different screens an illustration came up showing only 2-wheels active. So... the drive system is monitored and activated deactivated by the auto, not me? Anyone know the answer before I pull out that "thing" called an owners manual?
