Pa ssive side impact pr otection is an additional
Pa rking Assist PARKTRONIC function which
wa rnsth e driver about obs tacles at the side of
th eve hicle. A warning is issued when obs tacles
are de tected between the front and rear de tec‐
tion range. In order for an object on the side to
be de tected, the sensors in the front and rear
bumper must firs t de tect the object while you
are driving past it.
During the parking procedure or manoeuvring,
objects are de tected as theve hicle drives past.
If yo usteer in the direction of a de tected obs ta‐
cle and there is a risk of a lateral collision, a
wa rning is issued. The segments on the sides
light up yellow or red, depending on the dis tance
to the obs tacle. Segment colour depending on distance
