Good Question. I'm not sure, but you cant go wrong with stopping before engaging 4wd. The 4wd button is on the shift know I believe, so it can probably be done both ways. There are some Subi owners on this site, i'm sure they will peep up! -mark
I shift on the fly, I was told by the guys where I bought it not to engage it while doing 80! I usually do it going 10 - 15 km/h...
I shift on the fly, too. In fact, mine usually won't engage unless it's rolling. Sometimes I'll slip it into 4WD as I come up to an icy intersection, accelerate away, then switch back into 2WD. I wouldn't recommend doing it on glare ice, but I've shifted into and out of 4WD at speeds as high as 80 KM/H. Colin
Thank you everyone for the answers! I didn't want to be rolling along, shift, and then be not rolling along!!
you shouldn't need to shift into 4wd at 80 km/h. but best not to be on the throttle when you do at any speed.
