Camera and Sensors
F o r w a r d s e n s i n g c a m e r a ( F S C )
The Forward Sensing Camera (FSC) determines the conditions ahead of the vehicle while
traveling at night and detects traf¿ c lanes. The following systems also use the Forward
Sensing Camera (FSC).
 


y High Beam Control system (HBC)



y Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS)



y Smart Brake Support (SBS)
The Forward Sensing Camera (FSC) is installed at the top of the windshield near the
rearview mirror.
Refer to Forward Sensing Camera (FSC) on page 4-137 .
Radar sensor (front)
The radar sensor (front) functions by detecting the radio waves reÀ ected off a vehicle ahead
sent from the radar sensor. The following systems also use the radar sensor (front).
 


y Mazda Radar Cruise Control (MRCC)



y Distance Recognition Support System (DRSS)



y Smart Brake Support (SBS)
The radar sensor (front) is mounted behind the radiator grille.
Refer to Radar Sensor (Front) on page 4-140 .
Laser sensor (front)
The laser sensor (front) emits a near-infrared laser beam and receives the beam reÀ ected
off the reÀ ective surface of a vehicle in front, and the detected beam is then used for
measurement. The following systems also use the laser sensor (front).
 


y Smart City Brake Support (SCBS)



y Smart Brake Support (SBS)

Radar sensors (rear)
The radar sensors (rear) function by detecting the radio waves reÀ ected off a vehicle
approaching from the rear or an obstruction sent from the radar sensors. The following
systems also use the radar sensors (rear).
 


y Blind Spot Monitoring (BSM)



y Rear Cross Traf¿ c Alert (RCTA)

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


y The selector lever is shifted to reverse (R) and the vehicle is reversing. 



y In the following cases, the Blind Spot Monitoring (BSM) warning indication/warning
light turns on and operation of the system is stopped. If the Blind Spot Monitoring (BSM)
warning indication/warning 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
indicator 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
detection area of the radar sensors (rear) is set at the road width of expressways.

y In the following case, the À ashing of the Blind Spot Monitoring (BSM) warning indicator
light, and the activation of the warning sound and the warning screen indicator display
may not occur or they may be delayed.
 


y A vehicle makes a lane change from a driving lane two lanes over to an adjacent lane.



y Driving on steep slopes.



y Crossing the summit of a hill or mountain pass.



y The turning radius is small (making a sharp turn, turning at intersections).



y When there is a difference in the height between your driving lane and the adjacent
lane.
 


y Directly after pressing the Blind Spot Monitoring (BSM) OFF switch and the system
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 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.
 

y A Blind Spot Monitoring (BSM) warning indicator light may À ash or the warning beep
may be 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.
 


y In the following cases, it may be dif¿ cult to view the illumination/À ashing of the Blind
Spot Monitoring (BSM) warning indicator lights equipped on the door mirrors.
 


y Snow or ice is adhering to the door mirrors.



y The front door glass is fogged or covered in snow, frost or dirt.

 y The radar sensors (rear) of the Blind Spot Monitoring (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 Blind Spot Monitoring (BSM) is driven in a country other
than the U.S.A., Canada, or Mexico, the system has to be turned off using the Blind Spot
Monitoring (BSM) OFF switch.
 


y The system switches to the Rear Cross Traf¿ c Alert function when the selector lever is
shifted to the reverse (R) position.
  Refer to Rear Cross Traf¿ c Alert (RCTA) on page 4-102 .
Blind Spot Monitoring (BSM) Warning Indicator Light/Display Indicator/
Blind Spot Monitoring (BSM) 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 or at the rear of the vehicle using the
Blind Spot Monitoring (BSM) warning indicator light, the warning sound and the display
indicator (vehicles with multi-information display and active driving display) while the
systems are operational.
Blind Spot Monitoring (BSM) warning indicator lights
The Blind Spot Monitoring (BSM) warning indicator lights are equipped on the left and
right 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 turns on momentarily and
then turns off after a few seconds.

*Some models.
Distance Recognition Support System (DRSS) *
The Distance Recognition Support System (DRSS) measures the distance between your
vehicle and a vehicle ahead using a radar sensor (front) while the vehicle speed is 30 km/h
or faster (19 mph or faster), and indicates a recommended distance to maintain between
the vehicles. Furthermore, if your vehicle approaches a vehicle ahead more closely than
the appropriate distance to maintain between the vehicles according to the vehicle speed,
the area between the vehicle-ahead indication and the vehicle indication in the multi-
information display À ashes in white to advise the driver to keep a safer distance from the
vehicle ahead.
WARNING
Do not rely completely on the Distance Recognition Support System (DRSS) and always
drive carefully:
The Distance Recognition Support System (DRSS) provides advice for safer driving and
notifi es the driver of a recommended, safer distance to maintain with a vehicle ahead.
The ability to detect a vehicle ahead is limited depending on the type of vehicle ahead,
the weather conditions, and the traffi c conditions. Therefore, if the accelerator and brake
pedals are not operated correctly it could lead to an accident. Always verify the safety of
the surrounding area and depress the brake pedal or accelerator pedal while keeping a
safer distance from vehicles ahead or on-coming vehicles.
