PARKING SENSORS

(where provided)
They are located in the rear bumper
fig. 49 and their function is to detect the
presence of any obstacles near the rear
part of the car; they consequently inform
the driver, through an intermittent
acoustic signal.
49
ACTIVATION
The sensors are automatically activated
when reverse gear is engaged.
As the obstacle behind the vehicle gets
closer, the acoustic signal becomes more
frequent.
BUZZER
When reverse gear is engaged and there
is an obstacle behind the vehicle, an
acoustic signal is emitted which varies
according to the distance of the bumper
from the obstacle.
The frequency of the acoustic signal:
❒ increases as the distance between car
and obstacle decreases, culminating in a
continuous acoustic signal, when the
distance is less than approximately
30 cm;
❒ decreases if the distance from the
obstacle increases, until the signal ceases
entirely;
❒ is constant if the distance between
the vehicle and the obstacle is
unchanged;
❒ if this situation concerns the side
sensors, the signal will stop after
approximately 3 seconds to avoid, for
A0L0043
example, indications in the event of
manoeuvres along a wall.
If several obstacles are detected by the
sensors, only the nearest one is
considered.
