Driving and parking 277
Recovery mode is a function of the suspension
which can assist the driver on loose surfaces
(e.g. sand, snow) when freeing a vehicle which
has become stuck.
The vehicle body rocks in slow, vertical motions
when recovery mode has been activated. This
temporarily puts the wheels under greater load,
which means they have increased traction and
the vehicle is freed.
You can activate free driving mode via Off-road
Assist ( page 281).
