Monitoring
(BSM) Warning Beep
The BSM or Rear Cross Traffic Ale rt (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 active driving display)
(BSM) while the systems are operational.
BSM warning indicator 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

When the ignition is switched O N, the warning indicator light turns 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 indicator li ght 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 indica tor 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.

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 which are recognized
by the Forward Sensing Camera (FSC) or recorded in the navigation system while the
vehicle is driven.
The TSR displays the speed limit , do not enter, and traffic stop signs.
If the vehicle speed exceeds the speed limit sign indicated in the active drivi ng display while
the vehicle is driven, the system notifies the driver using the indication in the active driving
display 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 system SD card (Mazda genuine) is inserted in
the SD card slot. Consult an Authorized Mazda Dealer for details.

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 rear 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 danger using the Blind Spot Monitoring (BSM)
warning indicator lights and the warning buzzer.
Detection areas
Your vehicle
RCTA operation
1. The RCTA system operates when the shift lever (manual transax le) or the selector lever
(automatic transaxle) is shifted to the reverse (R) position.
2. If there is the possibility of a collision with an approaching vehicle, the Blind Spot
Monitoring (BSM) warning indicato r lights flashes and the warning beep is activated
simultaneously.

The RCTA warning indication in the rearview monitor also synchronizes with the Blind
Spot Monitoring (BSM) warning indicator light on the door mirro rs.
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.
•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).
•Driving on snow-covered roads for long periods.
•The temperature near the radar sensors 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.
•The vehicle speed when reversing is about 10 km/h (6 mph) or faster.
•The radar sensor (rear) detection area is obstructed by a nearby wall or parked vehicle.
(Reverse the vehicle to a position where the radar sensor detection area is no longer
obstructed.)
Your vehicle
•A vehicle is approaching directly from the rear of your vehicle.
Your vehicle
•The vehicle is parked on a slant.

•Directly after the Blind Spot Monitoring (BSM) system becomes operable using the
personalization feature.
•Radio wave interference from a radar sensor equipped on a nearby parked vehicle.
•In the following cases, it may be difficult to view the illumination/flashing of the Blind
Spot Monitoring (BSM) warning indicator lights equipped on the door mirrors.
•Snow or ice adheres to the door mirrors.
•The front door glass is fogged or covered in snow, frost or dirt.
•Turn off the RCTA system while pulling a trailer or while an accessory such as a bicycle
carrier is installed to the rear of the vehicl e. Otherwise, the radio waves emitted by the

Mazda Radar Cruise Control with Stop & Go function(MRCC with Stop & Go function)
*
The MRCC with Stop & Go function system is designed to maintain headway control*1
with a vehicle ahead according to your vehicle's speed using a radar sensor (front) to detect
the distance to the vehicle ahead and a preset vehicle speed without you having to use the
accelerator or brake pedals.
*1 Headway Control: Control of the distance between your vehicle and the vehicle ahead
detected by the Mazda Radar Cr uise Control (MRCC) system.
Additionally, if your vehicle s tarts closing in on the vehicle ahead such as if the vehicle
ahead brakes suddenly, a warning sound and a warning indication in the display are
activated simultaneously to alert you to maintain a sufficient distance between the vehicles.
If the vehicle ahead stops while you are following behind it, your vehicle will stop and be
held stopped automatically (stop hold control), and headway con trol will resume when you
resume driving the vehicle such a s by pressing the RES switch.
Also refer to the following before using the MRCC with Stop & G o function.
•AUTOHOLD (page 4-61)
•Forward Sensing Camera (FSC) (page 4-130)
•Radar sensor (front) (page 4-135)
WA R N I N G
Do not rely completely on the MRCC with Stop & Go function:
The MRCC with Stop & Go function system has detection limitations depending on the type of
vehicle ahead and its conditions, the weat her conditions, and the road conditions.
Additionally, the system may be unable to decelerate sufficiently to avoid hitting the vehicle
ahead if the vehicle ahead applies the brakes sudd enly or another vehicle cuts into the driving
lane, which could result in an accident.
Always drive carefully and verify the surrounding conditions and depress the brake pedal or
accelerator pedal while keeping a safer distance from vehicles ahead or on-coming vehicles.
Do not use the MRCC with Stop & Go function system in the following locations, using the
MRCC with Stop & Go function system at the following locations may result in an unexpected
accident:
 General roads other than highways (Driving under these conditions using the MRCC with
Stop & Go function system is not possible.)
 Roads with sharp curves and where vehicle
traffic is heavy and there is
insufficient space
between vehicles.
