Blind Spot Monitoring (BSM) System *
The Blind Spot Monitoring (BSM) 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) 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 turns on the
Blind Spot Monitoring (BSM) warning lights equipped on the door mirrors depending on
the conditions. If the turn signal 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 À 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 doors to about 50 m (164 ft) behind the vehicle.

Detection areas Your vehicle

WARNING
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
Blind Spot Monitoring (BSM) warning light may not fl ash or it 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.

(BSM) OFF indicator light in the instrument cluster is turned off.
 


y The vehicle speed is about 10 km/h (6.3 mph) or faster. 



y The Blind Spot Monitoring (BSM) will not operate under the following circumstances. 



y The vehicle speed falls below about 10 km/h (6.3 mph) even though the Blind Spot
Monitoring (BSM) OFF indicator light is turned off.
 


y The shift lever (manual transmission)/selector lever (automatic transmission) is shifted
to reverse (R) and the vehicle is reversing.
 


y In the following cases, the Blind Spot Monitoring (BSM) OFF indicator light turns on and
operation of the system is stopped. If the Blind Spot Monitoring (BSM) OFF indicator
light remains illuminated, have the vehicle inspected at an Authorized Mazda Dealer as
soon as possible.
 


y Some problem with the system including the Blind Spot Monitoring (BSM) warning
lights is detected.
 


y A large deviation in the installation position of a radar sensor (rear) on the vehicle has
occurred.
 


y There is a large accumulation of snow or ice on the rear bumper near a radar sensor
(rear). Remove any snow, ice or mud on the rear bumper.
 


y Driving on snow-covered roads for long periods.



y The temperature near the radar sensors (rear) becomes extremely hot due to driving
for long periods on slopes during the summer.
 


y The battery voltage has decreased. 



y Under the following conditions, the radar sensors (rear) cannot detect target objects or it
may be dif¿ cult to detect them.




y A vehicle is in the detection area at the rear in an adjacent driving lane but it does not
approach. The Blind Spot Monitoring (BSM) determines the condition based on radar
detection data.
 


y A vehicle is traveling alongside your vehicle at nearly the same speed for an extended
period of time.
 


y Vehicles approaching in the opposite direction.



y A vehicle in an adjacent driving lane is attempting to pass your vehicle.



y A vehicle is in an adjacent lane on a road with extremely wide driving lanes. The

becomes operable.
 


y 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.
 


y The Blind Spot Monitoring (BSM) warning lights may turn on in reaction to stationary
objects on the road or the roadside such as guardrails, tunnels, sidewalls, and parked
vehicles.

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.

activated several times when making a turn at a city intersection.
 


y Turn off the Blind Spot Monitoring (BSM) while pulling a trailer or while 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.

Warning Beep
The Blind Spot Monitoring (BSM) or Rear Cross Traf¿ c Alert (RCTA) system noti¿ es the
driver of the presence of vehicles in adjacent lanes to the rear of your vehicle using the
Blind Spot Monitoring (BSM) warning lights and the warning beep while the systems are
operational.
Blind Spot Monitoring (BSM) warning lights
The Blind Spot Monitoring (BSM) warning lights are equipped on the left and right door
mirrors. The warning lights turn on when a vehicle approaching from the rear in an adjacent
lane is detected.


When the ignition is switched ON, the malfunction warning light turns on momentarily and
then turns off after a few seconds.
Forward driving (Blind Spot Monitoring (BSM) system operation)
The Blind Spot Monitoring (BSM) system detects vehicles approaching from the rear and
turns on the Blind Spot Monitoring (BSM) warning lights equipped on the door mirrors
according to the conditions. Additionally, while a Blind Spot Monitoring (BSM) warning
light is illuminated, if the turn signal lever is operated to signal a turn in the direction
in which the Blind Spot Monitoring (BSM) warning light is illuminated, the Blind Spot
Monitoring (BSM) warning light À ashes.
