Mazda 2: Blind Spot Monitoring (BSM) System

Mazda2 DJ 2014–2020 Owners Manual / When Driving / i-Activsense / Blind Spot Monitoring (BSM) System

The Blind Spot Monitoring (BSM) system is designed to assist the driver in checking the area to the rear of the vehicle on both sides during lane changes by alerting the driver to the presence of vehicles approaching from the rear in an adjacent lane.

The Blind Spot Monitoring (BSM) system detects vehicles approaching from the rear while travelling in the forward direction at a speed of 30 km/h (19 mph) or faster and turns on the Blind Spot Monitoring (BSM) warning lights equipped on the door mirrors depending on the conditions. If the direction indicator lever is operated to signal a lane change in the direction in which the Blind Spot Monitoring (BSM) warning light is illuminated, the system warns the driver of a vehicle in the detection area by fl ashing the Blind Spot Monitoring (BSM) warning light and activating a beep sound.

The detection area on this system covers the driving lanes on both sides of the vehicle and from the rear part of the front doors to about 50 m (164 ft) behind the vehicle.
