Opel INSIGNIA 2017 Owner's Manual page 211

The system has four ultrasonic
parking sensors each in the rear and
front bumper.
Activation
The system is activated automatically
at a speed up to 11 km/h.
An illuminated LED in the parking
assist button r indicates that the
system is ready to operate.
If r is switched off within an ignition
cycle, the front parking assist is
deactivated. If vehicle speed has
exceeded 25 km/h beforehand,
parking assist will be reactivated
when speed drops below 11 km/h.
When the system is deactivated, the
LED in the button extinguishes and
Park Assist Off pops-up in the Driver
Information Centre.
Driving and operating
Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles in front of the
vehicle in a distance range up to 80
cm and against potentially hazardous
obstacles behind the vehicle in a
distance range up to 50 cm while a
forward gear is engaged, or up to 1.5
m while reverse gear is engaged.
Depending on which side of the
vehicle is closer to an obstacle, you
will hear acoustic warning signals in
the vehicle on the respective side.
The interval between the sounds
becomes shorter as the vehicle gets
closer to that obstacle. When the
distance is less than approx. 30 cm,
the sound is continuous.
Additionally, the distance to rear and
front obstacles is displayed by
changing distance lines in the Driver
Information Centre 3 113 or,
depending on the version, on the Info-
Display 3 120.
