It is at this time I would normally suggest that as you are probably new to LR ownership an owners handbook would be handy as thay are packed with loads of information regarding the operation & layout of controls (including the location of the fuse-box and what fuses should be fitted), capacities, basic maintenance etc and at about £12 for a brand-new copy good value as well (while you are at it, buy a Haynes workshop manual as well as they are also very handy).
I say normally because the last time I mentioned it people replied with all sorts of reason why not to buy one including :-didn't know they were still available (fair enough but had you looked or asked?), too expensive (£12!?!), owned LR's for 25yrs so why should I buy one (ok but my comments were directed to a new owner), don't read manuals, rather just 'get in there' and work it out myself (bet you don't read the handbook when you get a new video either), most LR's have been modified so much over the years that nothing in the handbook is still relevant(???) etc etc.
If you fancy one (answers lots of questions which you haven't even asked yet) look at the LRE bookshop amongst other places.
