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 by notifying the driver of the p resence of vehicles
approaching from the rear in an adjacent lane.
The BSM detects vehicles approaching from the rear while travel ing 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
multi-information display and active driving display).
If the turn signal lever is operated to signal a turn in the direction in which the BSM
warning indicator light is illumi nated while the approaching vehicle 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 display (vehicles with
multi-information display and 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 d oors to about 50 m (164 ft) behind the vehicle.
Detection areas
Your 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.

long periods on slopes during the summer.
The battery voltage has decreased.
Under the following conditions, the radar sensors (rear) cannot detect target objects or it
may be difficult to detect them.
A vehicle is in the detection area at the rear in an adjacent driving lane but it does not
approach. The BSM determines the condition based on radar detection data.
A vehicle is traveling alongside your vehicle at nearly the same speed for an extended
period of time.
Vehicles approaching in the opposite direction.
A vehicle in an adjacent driving lane is attempting to pass your vehicle.
A vehicle is in an adjacent lane on a road with extremely wide driving lanes. The

When there is a difference in the height between your driving lane and the adjacent
lane.
Directly after the BSM system becomes operable by changing the setting.
If the road width is extremely narrow, vehicles two lanes over may be detected. The
detection area of the radar sensors (rear) is set according to the road width of
expressways.
The BSM warning indicator light may turn on and the vehicle detection screen may be
displayed in the display in reaction to stationary objects (guardrails, tunnels, sidewalls,
and parked vehicles) on the road or the roadside.
Objects such as guardrails and concrete walls
running alongside the vehicle. Places where the width between guardrails or
walls on each side of the vehicle narrows.
The walls at the entrance and exits of tunnels,
turnouts.
A BSM warning indicator light may flash or the warning beep may be activated several
times when making a turn at a city intersection.
Turn off the BSM while pulling a trailer or wh
ile an accessory such as a bicycle carrier is
installed to the rear of the vehicle. Otherwise, the radar’s radio waves will be blocked
causing the system to not operate normally.
In the following cases, it may be difficult to view the illumination/flashing of the BSM
warning indicator lights equipped on the door mirrors.
Snow or ice is adhering to the door mirrors.
The front door glass is fogged or covered in snow, frost or dirt.
The radar sensors (rear) of the BSM may be regulated under the radio wave related laws
of the country where the vehicle is driven. The sensors in this system are approved for use
in the U.S.A. (including territories), Canada, and Mexico. If a vehicle with a BSM is
driven in a country other than the U.S.A., Canada, or Mexico, the system has to be turned
off by changing the setting on the center display.
The system switches to the Rear Cross Traffi c Alert (RCTA) function when the shift lever
(manual transaxle) or the selector lever (automatic transaxle) is shifted to the reverse (R)
position.

Traffic Sign Recognition System (TSR)*
The TSR helps prevent the driver from overlooking traffic signs, and provides support for
safer driving by displaying traffic signs on the active driving display/instrument cluster
which are recognized by the Forward Sensing Camera (FSC) or rec orded in the navigation
system while the v ehicle is driven.
The TSR displays the speed limit, do not enter, and traffic sto p signs.
If the vehicle speed exceeds the speed limit sign indicated in the active driving display/
instrument cluster while the vehicle is driven, the system noti fies the driver using the
indication in the active driving display/instrument cluster and a warning sound.
NOTE
The TSR is not supported in some countries or regions. For information concerning the
supported countries or regions, consult an Authorized Mazda Dealer.
The TSR operates only if the navigation syst em SD card (Mazda genuine) is inserted in
the SD card slot. Consult an Authorized Mazda Dealer for details.
