The first problem you'll face, is that the cream tends to separate in the jar, leaving you something that looks like clotted cream that's gone off!
No problem - loosen the lid a little, and pop in the microwave for 30 secs on high - re-tighten the lid, and shake well.
You'll end up with a warm liquid that looks like a nice alfredo sauce or brandy sauce - creamy and smooth, and ready to apply.
Next - put your Land Rover in full sun - and close all the doors and windows - we want the seats to get warm/hot as this aids the absorption of the cream.
Take a soft cloth, and apply the warm hide cream evenly all over the leather parts of the seats - it'll look like cr@p as it goes on, but don't worry!
If you get any on the plastic, or seat belts, or carpet, just wipe off with a soft cloth, no problems.
DON'T APPLY TO THE SUEDE-LIKE LEATHER - IT WILL PROBABLY STAIN!
When you have a good even coat over the seats - close the door and walk away for an hour - letting the sun do it's thing.
