PARKING SENSORS IF EQUIPPED
The vehicle’s parking sensors are located in the rear
bumper, and will detect the presence of any obstacles
near the rear part of the vehicle while moving in
REVERSE gear. The driver is then informed through an
intermittent acoustic signal.
Activation/Deactivation
The sensors are automatically activated when REVERSE
gear is engaged. As the obstacle behind the vehicle gets
closer, the acoustic signal becomes more frequent.
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 ob-
stacle decreases, culminating in a continuous acous-
tic signal when the distance is less than approxi-
mately 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 con-
cerns the side sensors, the signal will stop after
approximately 3 seconds, for example, 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 parking sensor
display screen appears in the instrument cluster.
