+1 here. AWD is meant to be transparent to the Driver. VSA is the one that lights up if it is on. I've owned plenty of AWD CUV/SUV's and none of them have ever used a light to tell me: " Hey Pal; your ass is slipping so I'm engaging other wheels to drive". My Subaru was a bit easier to tell as when the AWD was active; it would grab like glue and you would right the car really quick and there would be a light "thunk" in the rear end when it dis-engaged. The 12 CR-V actually uses the AWD VERY frequently now. Each time the car begins motion from a stop; the AWD is engaged. The bottom line!? If the AWD light is on; you are in trouble.I don't think you would ever want that AWD light to come on during a drive...means something is wrong.
...or press the button that turns VSA (traction control) off.You could always find a muddy hill and see if you can drive up it. That's kind of what I did. I rolled down the windows and watched to see if the back tires would kick up rocks while I was going up this steepish loose gravel roadish. I don't think I ever saw the light come on though. Is it for when something is wrong with the AWD? I did get the traction control light to come on once when I tried to fish tale around this turn on a gravel road. Traction control kicked in and the rear wheels kept too much grip and took all the fun out of it. Need to get an old Civic so I can have some fun around that road again.
