NOTE
•The BSM will operate when all of the following conditions are met:
•The ignition is switched ON.
•The BSM OFF indicator light in the instrument cluster is turned off.
•The vehicle speed is about 10 km/h (6.3 mph) or faster.
•The BSM will not operate under the following circumstances.
•The vehicle speed falls below about 10 km/h (6.3 mph) even though the BSM OFF
indicator light is turned off.
•The selector lever is shifted to r everse (R) and the vehicle is reversing.
•The turning radius is small (making a sharp turn, turning at intersections).
•In the following cases, the BSM OFF indicator light turns on and operation of the system
is stopped. If the BSM OFF indicator light re mains illuminated, have the vehicle inspected
at an Authorized Mazda Dealer as soon as possible.
•Some problem with the system including the BSM warning indicator lights is detected.
•A large deviation in the installation position of a radar sensor (rear) on the vehicle has
occurred.
•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.
•Driving on snow-covered roads for long periods.
•The temperature near the radar sensors (rear) becomes extremely hot due to driving for
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
detection area of the radar sensors (rear) is set at the road width of expressways.
•In the following case, the flashing of the BS M warning indicator light, and the activation
of the warning sound and the warning screen indicator display may not occur or they may
be delayed.
•A vehicle makes a lane change from a driving lane two lanes over to an adjacent lane.
•Driving on steep slopes.
•Crossing the summit of a hill or mountain pass.

•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
and 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), and Canada. If a vehicle with a BSM is driven in a
country other than the U.S.A., or Canada, the system has to be turned off by changing the
setting on the center display.
•The system switches to the Rear Cross Traffic Alert (RCTA) function when the selector
lever is shifted to the reverse (R) position.

▼Blind Spot Monitoring (BSM) Warni
ng Indicator Light/Display Indicator/Blind
Spot Monitoring (BSM) Warning Beep
The BSM or Rear Cross Traffic Al ert (RCTA) system notifies the driver of the presence of
vehicles in adjacent lanes or at the rear of the vehicle using the BSM warning indicator
light, the warning sound and the display indicator (vehicles wi th multi-information display
and active driving display) (BSM) while the systems are operati onal.
BSM warning in dicator lights
The BSM warning indicator lights are equipped on the left and r ight door mirrors. The
warning indicator lights turn on when a vehicle approaching from the rear in an adjacent
lane is detected.
When the ignition is switched ON, the warning indicator light t urns on momentarily and
then turns off after a few seconds.
Forward driving (BSM operation)
The BSM detects vehicles approaching from the rear and turns on the BSM warning
indicator lights equipped on the door mirrors according to the conditions. Additionally,
while a BSM warning i ndicator light is illuminated, if the turn signal lever is operated to
signal a turn in the direction in which the BSM warning indicat or light is illuminated, the
BSM warning indicator light flashes.
Reverse driving (Rear Cross Traf fic Alert (RCTA) system operation)
The Rear Cross Traffic Alert (RCTA) system detects vehicles app roaching from the left and
right of your vehicle and flashes the BSM warning indicator lig hts.

Function for cancelling illumination dimmer
If the BSM warning indicator lights turn on when the parking lights are turned on, the
brightness of the BSM warning indicator lights is dimmed.
If the BSM warning indicator light s are difficult to see due to glare from surrounding
brightness when traveling on snow-covered roads or under foggy conditions, press the
dimmer cancellation button to cancel the dimmer and increase th e brightness of BSM
warning indicator light s when they turn on.

Rear Cross Traffic Alert (RCTA)*
The RCTA system is designed to assist the driver in checking the area to the rear of the
vehicle on both sides while the vehicle is reversing by alertin g the driver to the presence of
vehicles approaching the rear of the vehicle.
The RCTA system detects vehicles approaching from the left and right sides of the vehicle,
and the rear of the vehicle while the vehicle is being reversed out of a parking space, and
notifies the driver of possible d anger using the Blind Spot Mon itoring (BSM) warning
indicator lights and the warning buzzer.

RCTA operation
1. The RCTA system operates when the selector lever is shifted to the reverse (R) position.
2. If there is the po ssibility of a collision with an approachin g vehicle, the Blind Spot
Monitoring (BSM) warning indicator lights flashes and the warni ng beep is activated
simultaneously.

WA R N I N G
Always check the surrounding area visually before actually putting the vehicle in reverse:
The system is only designed to assist you in checking for vehicles at the rear when putting the
vehicle in reverse. Due to certain limitations with the operation of this system, the Blind Spot
Monitoring (BSM) warning indicator lights may not flash or it might be delayed even though
a vehicle is behind your vehicl e. Always make it your responsibility as a driver to check the
rear.
NOTE
•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.
•Some problem with the system including the Blind Spot Monitoring (BSM) warning
indicator lights has occurred.
