Pretty sure the LR3 and LR4 has the same 5 selectable Terrain Response modes. One of which is indeed "Sand".
Explanation taken from elsewhere on the web:
Sand: Starting off from rest in sand requires gentle throttle action, but once the vehicle is moving you want to get up on top and maintain enough speed to avoid sinking. So the TR system initializes the accelerator pedal softly, but then ramps up the response with increasing speed. In the sand setting, the transmission shifts up at higher RPM, and downshifts quicker as well, to keep the engine in its optimum power band. This prevents a sudden patch of very soft sand from bogging down the engine. HDC is not automatically activated in this program, nor are differential thresholds altered. Traction control is set to reduce wheel spin but also to induce less torque intervention, to maintain smooth power application. Meanwhile, the message centre displays steering information and warns if ride height has not been reached.
