GRASS/GRAVEL/SNOW
This program should be used where a firm surface is covered with loose or slippery material.
For deep snow and gravel it is recommended that the Sand program is selected.
If the vehicle is unable to gain traction in deep snow, switching Dynamic Stability Control (DSC) off may help. See SWITCHING DSC OFF. DSC should be switched on again, as soon as the difficulty is overcome. See SWITCHING DSC ON.
