Blind Spot Information (BSI) System
The RLX blind spot information (BSI) system assists drivers before making lane changes. When a vehicle in either adjacent lane is detected in one of the two alert zones—areas where the vehicle is close but difficult to spot—an indicator will appear on that side’s front door A-pillar close to the side mirror. If the driver activates the turn signal in the direction where a vehicle is detected in the alert zone, the pillar light begins to flash and an audible alert sounds. Several measures have been designed into the system to ensure that it is a helpful feature and never an annoyance.
