CAUTION: The blindspot monitoring system is designed as a driver aid not a safety device. The driver should always exercise due care and attention whilst driving.

There are two Blindspot Monitoring Control Module (BMCM)s and they are located in the corner of the rear bumper, one on each side.

Each BMCM connector has power, ground, High Speed (HS) Controller Area Network (CAN) comfort systems bus wires, and two private CAN bus wires.

The system uses two radar sensors, they are incorporated in each of a BMCMs, and are connected via a private CAN bus to exchange information with each other.

Each BMCM carries out an auto-alignment self-check every time when in use. This procedure can take up to an hour in some environments, however the operation of the blindspot monitoring system will continue to operate as normal.

The BMCM receives vehicle speed from the Anti-lock Brake System (ABS) control module on the HS CAN powertrain and comfort systems buses via the Body Control Module/Gateway Module (BCM/GWM) assembly. The system activates at 9 mph (15 km/h) and remains active until the speed lowers below 3 mph (5 km/h).
