WARNING Do not reduce the tire inflation pressure 
Do not reduce the tire inflation pressure before driving through sand. However, if you do so, remember to correct the tire inflation pressure before continuing your trip. Driving with reduced tire inflation pressure increases the risk of losing control of the vehicle and rolling over.

Observe the following rules when driving on sand:

select a higher vehicle level.
avoid high engine speeds.
select a shift range appropriate to the terrain.
drive quickly to overcome the rolling resistance. Otherwise, the vehicle could dig itself into the sand.
drive in the tracks of other vehicles if possible. Make sure that the ruts are not too deep, that the sand is firm enough and that your vehicle has sufficient ground clearance.
