selected.
The ROAD SUR FACE SCAN function de tects
areas of une venness in thero ad before you drive
ove rth em bymeans of a multifunction camera.
This reduces chassis mo vements.

Re
covery mode is a function of the suspension
which can assist the driver on loose sur faces
(e.g. sand, snow) when freeing a vehicle which
has become stuc k.
The vehicle body rock s in slo w,vertical motions
when reco very mode has been activated. This
te mp orarily puts the wheels under greater load,
which means they have inc reased traction and
th eve hicle is freed.
Yo u can activate free driving mode via Off- road
Assist (/ page276).
