You must have had very little snow. I Took my RX400h out yesterday in Cumbria , there was very poor traction and when I came close to the main road,driving quite slowly and braked gently, there was no grip and we nearly slid into a 4x4. I am a new member so maybe I am expecting too much, all I can say is that my previous cars performed far better in much worse conditions. I have studied the manual but cannot find anything that I should have engaged for driving in snow/ice it all appears to be linked to this mystical VDIM system or have I missed something?
