Had to travel from Philly to NoVA today. Really tested the merit of my AWD. Made it in four and half hours. Not bad considering the weather...<p>The S60 wasn't as stable in the snow as I thought it would be. I feel more secure when I drive my Cross-Country. <p>Anyone know how WINTER MODE (WM) works? Does it just make sure the car starts in a lower gear? Is it okay to use WM at speed? Like over 30MPH?<p>The most notable thing during my drive today was how much the car started shuddering...I was travelling around 40 to 50 mph and my car was shaking like crazy. I'm not sure if it was because of all the snow build up on the front spoiler, but I couldn't figure out any other reason. Any other thoughts?<p>Question: On the dash on the right cluster gauge, when the yellow triangle with an exclaimation point starts blinking, is that the only time when the AWD is engaged? If I read correctly, the Haldex system works 95% front - 5% rear under normal conditions...then just assigns power to the corresponding wheel that is slipping. Right? <p>TIA.
