Hello everybody new member here 
I want to thank the members and moderators of this amazing forum. I’ve been exploring it for the past 2 days, and went through a lot of helpful and great information.
I have a 2015 Landcruiser GXR 4.0. I live in a country were we experience maximum 1-2 cm of snow for just couple of hours per year. Every 5-10 years we get a big storm (last one in February 2015), and according to local forecast this will happen tomorrow night 40-50 cm of snow. So this will be my first time driving my car in real snow.
While doing my research for how to drive my car in snow, thanks again for this form, I got good understanding of how low gear, central differential, rear differential works (My vehicle not equipped with crawl or multi terrain function). I will be driving mainly on roads with 40-50 cm of snow (country is not well equipped to deal with snow as it’s a rare thing to happen so they open highways and main roads, and wait for the rest to melt). When it snows it’s an official holiday
According to my understanding I’ll need to drive with L4 and central differential locked as the terrain in my area is mostly hills and mountains. If My vehicle is stuck I’ll lock my rear differential and try to free it. Correct me if I’m wrong please. I’ll drive in low speeds probably less than 25km/h and make sure not to take sharp turns to avoid transmission wind up.
I have couple of questions that I couldn’t find answers to while reading in this forum or the user manual. I would really appreciate your help guys, and any advise or comment is more than welcome.
According to my understanding when I change from H4 to L4 the central differential will be locked automatically. My question is, in what situation I’ll need to drive with L4 and central differential unlocked? And in what situation I’ll need to drive in H4 with central differential locked. I’m sorry if it’s a stupid question but couldn’t really figure it out.
Thanks in advance for everyone, and hope you’ll have a wonderful day.
I’ll attach a picture of the previous snow storm so you get an idea of how the roads will be. At that time I had a 4X4 2005 Jeep Grand Cherokee with no low gear and no central differential that didn’t move at all
Thanks again
