Refer to the General recommendations on the
use of driving and manoeuvring aids.
This system includes sensors, placed on the
sides of the bumpers, and warns the driver of
the potentially dangerous presence of another
vehicle (car, truck, motorcycle) in the blind spot
areas of their vehicle (areas hidden from the
driver's field of vision)...

minutes before moving off, to ensure the
correct operation and durability of the
