Hi,
 I have a 2006 Isuzu Rodeo (Dmax) 3litre jeep.

I find when I use 4H for slippery Icy conditions, my car slows down to a
halt while turning corners, and then it doesn't move unless I really
accelerate and push it to go!

Why is this? I read in the manual, that you use 4H for slippery road
conditions, but only 4L when your really stuck..

Surely my truck should be able to operate normally (even when turning
corners) in 4H??

Any ideas

Thanks

Jonathan
