Acoustic Signal
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 vehicle and obstacle
decreases, culminating in a continuous acoustic signal
when the distance is less than approximately 12 in (30 cm).
Decreases if the distance from the obstacle increases,
until the signal ceases entirely.
Remains constant if the distance between vehicle and
obstacle remains unchanged; if this situation concerns
the side sensors, the signal will stop after approxi-
mately 3 seconds to avoid, for example, indications in
the event of manoeuvres along a wall.
If several obstacles are detected by the sensors, only the
nearest one is considered.
Indications On Display If Equipped
When the sensors are activated, the screen appears on the
display.
Obstacle presence and distance information is therefore
provided both by the acoustic signal and the instrument
panel display.
