▼Canceling Operation of Blind Spot
Monitoring (BSM)
The BSM system can be set to inoperable.
Refer to Personalization Features on page
9-12.
When the BSM is set to inoperable, the
BSM and Rear Cross Traffic Alert
(RCTA) systems are turned off and the
BSM OFF indicator light in the instrument
cluster turns on.
NOTE
When the ignition is switched OFF, the
system status before it was turned off is
maintained. For example, if the ignition is
switched OFF while the BSM and Rear
Cross Traffic Alert (RCTA) systems are
operational, the BSM and Rear Cross
Traffic Alert (RCTA) systems remain
operational the next time the ignition is
switched ON.

Stop sign
WA R N I N G
Always check the traffic signs visually while driving.
The TSR helps prevent the driver from overlooking traffic signs and provides support for safer
driving. Depending on the weather conditions or problems with traffic signs, a traffic sign may
not be recognized or a traffic sign different from the actual traffic sign may be displayed.
Always make it your responsibility as a driver to check the actual traffic signs. Otherwise, it
could result in an accident.
NOTE
The TSR does not operate if there is a malf unction in the Forward Sensing Camera (FSC).
Under the following conditions, the TSR may not operate normally.
An object placed on the dashboard is reflected in the windshield and picked up by the
camera.
Heavy luggage is loaded in the luggage compartment or on the rear seat and the
vehicle is tilted.
The tire pressures are not adjusted to the specified pressure.
Tires other than standard tires are equipped.
The vehicle is driven on the ramp and surrounding area to or from a rest area or a
tollgate on a highway.
When surrounding brightness suddenly changes such as when entering or exiting a
tunnel.
The illumination of the headlights is weakened because of dirt or the optical axis is
deviated.
The windshield is dirty or foggy.

Strong light is directed at the front of the vehicle (such as backlight or high-beam
headlights of on-coming vehicles).
The vehicle is making a sharp turn.
Strong light reflects off the road.
A traffic sign is in a position which makes it difficult to reflect the light from the
vehicle's headlights, such as when the vehicle is driven at night or in a tunnel.
The vehicle is driven under weather conditions such as rain, fog, or snow.
The stored map data for the navigation system is not current.
A traffic sign is obscured by mud or snow.
A traffic sign is concealed by trees or a vehicle.
A traffic sign is partially shaded.
A traffic sign is bent or warped.
A traffic sign is too low or too high.
A traffic sign is too bright or too da rk (including electronic traffic signs).
A traffic sign is too big or too small.
There is an object similar to the traffic sign being read (such as another traffic sign or
other signs resembling it).
The TSR does not operate if the active dr iving display is set to non-display.
The TSR can be set to inoperable.

malfunctions, check the vehicle c onditions or have it inspected by an Authorized Mazda
Dealer according to the conte nt of the displayed message.
Refer to Warning/Indicator Lights on page 4-23.
NOTE

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.
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.

(With rear view monitor)
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 vehicle. 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).

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 vehic le. Otherwise, the radio waves emitted by the
radar will be blocked causing the system to not operate normally.

Slopes with a steep gradient ( The vehicle ahea d may not be detected correctly, your vehicle
may slide while stopped by the stop hold cont rol, and it may accelerate suddenly after it
starts moving.)
For safety purposes, switch the MRCC system off when it is not being used.
CAUTION
If your vehicle is towed or you are towing something, switch the MRCC system off to prevent a
miss-operation.
NOTE
The MRCC system does not detect the following as physical objects.
Vehicles approaching in the opposite direction
Pedestrians
Stationary objects (stopped vehicles, obstructions)
If a vehicle ahead is traveling at an extremely low speed, the system may not detect it
correctly.
During headway control travel, do not set the system for detection of two-wheeled
vehicles such as motorcycles and bicycles.
Do not use the MRCC system under conditions in which close proximity warnings are
frequently activated.
During headway control travel, the system accelerates and decelerates your vehicle in
conjunction with the speed of the vehicle ahead. However, if it is necessary to accelerate
for a lane change or if the vehicle ahead brakes suddenly causing you to close in on the
vehicle rapidly, accelerate using the accelerator pedal or decelerate using the brake
pedal depending on the conditions.
While the MRCC system is in use, it does not cancel even if the selector lever (automatic
transaxle)/shift lever (manual transaxle) is operated and any intended engine braking will
not occur. If deceleration is required, lower the vehicle speed setting or depress the brake
pedal.
The sound of the automatic brakes operating may be heard, however, it does not indicate
a problem.
The brake lights turn on while the MRCC automatic braking is operating.
