Approval of blind-spot information systems (BSIS).

Blind spot warning system provides added safety. It is designed to warn the driver about approaching vehicle in the blind spot. The warning system can be activated or deactivated from the infotainment system. When there is an approaching vehicle the right adjacent area or in the left adjacent area, the warning lamp on the corresponding ORVM icon will be turned on. 

When there is an approaching vehicle in the left or right adjacent area and you intend to change the lane by turning on the indicator the warning lamp on the corresponding ORVM will start flashing. The system alerts the driver of potentially hidden vehicles by displaying a visual signal. The tecnology is based on radar system.


The effectiveness of the BSIS shall not be adversely affected by magnetic or electrical fields. This shall be demonstrated by compliance with the technical requirements and transitional provisions of UN Regulation No. 10. The BSIS shall warn the driver, by means of an optical signal, acoustical signal, haptic signal or any combination of these signals, when the risk of a collision increases. It may be deactivated manually. 

In the case of a manual deactivation, it shall be reactivated upon each activation of the vehicle master control switch. The vehicle manufacturer shall ensure that the number of false-positive warnings due to the detection of static non-VRU objects such as cones, traffic signs, hedges and parked cars shall be minimized. However it may give an information signal when a collision is imminent. The BSIS shall automatically deactivate if it cannot operate properly due to its sensoring devices being contaminated by ice, snow, mud, dirt or similar material or due to ambient light conditions. It shall automatically reactivate when the contamination disappears and normal function has been verified.
