optimises wheel spin to guarantee the
best acceleration based on the
available traction. Recommended in
cases of deep snow and steep
inclines.
This mode is active up to a speed of
50 km/h.
Mud mode 4
This mode allows considerable wheel
spin at start-up for the wheel with the
least grip, this removes mud and re-
establishes traction.Simultaneously, the wheel with the
most grip is provided with the most
torque possible.
This mode is active up to a speed of
80 km/h.
Sand mode 1
This mode allows a small amount of simultaneous wheel spin on the two drive wheels, enabling the vehicle to
advance and reduce the risk of
sinking.
