Land Rover's Terrain Response explained

Greetings! 

I recently purchased a 2011 Land Rover LR4 HSE with the heavy-duty package.  I’d like to know in detail how the Terrain Response system works so that I can make full use of it.  Simple labels on the settings, like “Snow,” “Sand,” etc., are not enough! In particular, I’d like to know all of the vehicle’s attributes that are controlled by the Terrain Response system (such as throttle response, transmission, brakes, electronic traction control) and how each is modified in each of the settings.  

I have tried to get this information from Land Rover USA and from my dealer with no success.  Surely this information is available. How can I find it? 

Thanks!
