The blind spot information system (BLIS) is an auxiliary system designed to help the vehicle's driver when moving sideways. The blind spot information system (BLIS) consists of two cameras integrated in the external rear view mirrors and two LEDs located in the panel at the front of the inside of the respective windows.

The central electronic module (CEM) communicates with the left camera module (LCM) and the right camera module (RCM) via serial communication.

The blind spot information system (BLIS) is always activated automatically when the ignition is switched on, but it is possible to deactivate and activate the blind spot information system (BLIS) using one of the switches on the dashboard environment panel on the climate control module (CCM). A signal is then transmitted via the central electronic module (CEM) to the left camera module (LCM) and the right camera module (RCM) with a request to deactivate or activate the blind spot information system (BLIS).

When reverse gear is engaged, the blind spot information system (BLIS) is deactivated.

The blind spot information system (BLIS) can be diagnosed.
