When it is difficult to generate traction
MUD & SAND mode provides the largest amount of tire slippage, followed by LOOSE
ROCK, MOGUL and ROCK mode.
Drivability can be improved by selecting a mode which provides a smaller amount of tire
slippage than the current mode when the amount of tire slippage is large, or conversely
selecting a mode which provides a larger amount of tire slippage than the current mode
when the amount of tire slippage is small.
