According to the handbook I’m not supposed to use 4H except in slippy conditions not permanently. How slippy is sloppy?

I’m heading North West there is probably go8ng to be snow and I’ve already had it over steering today on a tight corner.

So Can I put it in 4wd in snow,slush or just icy or is it reserved for mud only.

Hyundai terracan by the way.

It sounds the same as my elderly Ford Ranger. It needs to be slippery enough to allow a little bit of spin front and rear to prevent any transmission wind up. If you can't get the power down without sliding around or you won't move at all then engage 4wd. Just don't go around any corners on dry, grippy paved roads.

Thanks that what I was worried about blowing the transmission or diffs.

Ok so leave it alone unless having issues then should be ok.

I remember reading something in a very old Land Rover Owner magazine (I think) that really, transmission lock up is likely only an issue at sustained speeds above 50mph. At those speeds 4H probably wasn't required anyway.

Some may say that they've had it at lower speeds, but I've never really seen too many examples. I've seen a lot more examples (particularly when I lived in Canada where pickups are far more common) of people only driving in 2H but because they were in a pickup thinking they were invincible in slippy conditions, then spinning and writing vehicle off - or worse.

Ultimately if you're worried, put it in 4H and drive accordingly.

Thanks

The mighty terracan managed the passes in the lakes like a champ ice snow no issues.

I think it just weighed that much it crushed all beneath it.

Good to know for the next lot of snow we have.

If you're not getting stuck, I wouldn't use it on the road at any kind of speed.

It's not just potential damage from bind up; if you've got no diff (or locked centre) it'll handle like an utter pig too. When you steer, you'll be forcing the axels to try and spin at the same rate, so overspeeding at least one wheel.
