warning MAZDA MODEL 3 HATCHBACK 2018 (in English) Workshop Manual

Blind Spot Monitoring (BSM)*
The BSM is designed to assist the driver in checking the area to the rear of the vehicle on
both sides during lane changes b y notifying the driver of the presence of vehicles
approaching from the rear in an adjacent lane.
The BSM detects vehicles approaching from the rear while traveling in the forward
direction at a speed of 10 km/h (6.3 mph) or faster and notifie s the driver by turning on the
BSM warning indicator light and displaying the vehicle detectio n screen (vehicles with
active driving display).
If the turn signal lever is operated to signal a turn in the di rection in which the BSM
warning indicator light is illuminated while the approaching ve hicle is detected, the BSM
notifies the driver of possible danger by turning on the BSM wa rning indicator light, and by
activating the warning sound and the warning screen indicator d isplay (vehicles with active
driving display).
The detection area on this system covers the driving lanes on b oth sides of the vehicle and
from the rear part of the front doors to about 50 m (164 ft) behind the vehicle.

WA R N I N G
Always check the surrounding area visually before making an actual lane change:
The system is only designed to assist you in checking for vehicles at your rear when making a
lane change. Due to certain limitations with the operation of this system, the BSM warning
indicator light, the warning sound and the warning screen indicator display may not activate
or they might be delayed even though a vehicle is in an adjacent driving lane. Always make it
your responsibility as a driver to check the rear.
