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

th e sensors in the front and rear bumper must
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‐
