▼Camera and Sensors
Forward sensing camera (FSC)
The Forward Sensing Camera (FSC)
determines the conditions ahead of the vehicle while
traveling at night and detects traffic lanes. The following sys tems also use the Forward
Sensing Camera (FSC).
High Beam Control system (HBC)
Lane Departure Warning System (LDWS)
Traffic Sign Recogn ition System (TSR)
Smart City Brake Support (SCBS)
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 4-103.
Radar sensors (rear)
The radar sensors (rear) function by detecting the radio waves reflected off a vehicle
approaching from the rear or an obstruction sent from the radar sensors. The following
systems also use the radar sensors (rear).
Blind Spot Monitoring (BSM)
Rear Cross Traffic Alert (RCTA)
The radar sensors (rear) are installed inside the rear bumper, one each on the left and right
sides.
Refer to Radar Sensors (Rear) on page 4-107.

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

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 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.
The walls at the entrance and exits of tunnels,
turnouts.
A BSM warning light may flash or the warnin
g beep may be activated several times when
making a turn at a city intersection.
Turn off the BSM while pulling a trailer or while an accessory such as a bicycle carrier is
installed to the rear of the vehicle. Otherwis e, 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 lights equipped on the door mirrors.
Snow or ice is adhering to the door mirrors.
The door glass is fogged or covered in snow, frost or dirt.

The Forward Sensing Camera (FSC) recognizes the speed limit sign and the vehicle is
driven for a certain distance after passing the sign.
Each sensor determines that the vehicle has changed direction of travel.
The Forward Sensing Camera (FSC) recognizes a new speed limit sign which differs
from the previous one (displays the new speed limit sign).
The speed limit sign stored in the navigatio n system is not read within a certain period
of time (if the Forward Sensing Camera (FSC) does not recognize a speed limit sign,
the speed limit sign stored in th e navigation system is displayed).
The vehicle speed exceeds the displayed speed limit sign by 30 km/h (19 mph) or more
after a certain period of time has elapse d since the speed limit sign was displayed.
(Except when there is information for the speed limit sign in the navigation system)
Do not enter signs
A do not enter sign is displayed when all of the following conditions are met.
The vehicle speed is about 60 km/h (37 mph) or slower.
The Forward Sensing Camera (FSC) recognizes a do not enter sign as a sign targeted
for your vehicle and the vehicle passes it.
When the Forward Sensing Camera (FSC) recognizes the do not enter sign and a certain
period of time has elapsed since the vehicle passed the sign, display of the do not enter
sign stops.

Always check the surrounding area visually before actually putting the vehicle in reverse:
The system is only designed to assist you in ch ecking for vehicles at the rear when putting the
vehicle in reverse. Due to certain limitations wi th 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.

Radar Sensors (Rear)*
Your vehicle is equipped with radar sensors (rear). The following systems also use the radar
sensors (rear).
Blind Spot Monitoring (BSM)
Rear Cross Traffic Alert (RCTA)
The radar sensors (rear) function by detecting the radio waves reflected off a vehicle
approaching from the rear or an obstruction sent from the radar sensor.
Radar sensors (rear)
The radar sensors (rear) are installed inside the rear bumper, one each on the left and right
sides.
Always keep the surface of the rear bumper near the radar senso rs (rear) clean so that the
radar sensors (rear) operate normally. Also, do not apply items such as stickers.
Refer to Exterior Care on page 6-54.
CAUTION
If the rear bumper receives a severe impact, the system may no longer operate normally. Stop
the system immediately and have the vehicle inspected at an Authorized Mazda Dealer.
NOTE
The detection ability of the radar sensors (rear) has limitations. In the following cases,
the detection ability may lower and the system may not operate normally.
The rear bumper near the radar sensors (rear) has become deformed.
Snow, ice or mud adheres to the radar sensors (rear) on the rear bumper.
Under bad weather conditions such as rain, snow and fog.
Under the following conditions, the radar sensors (rear) cannot detect target objects or it
may be difficult to detect them.
Stationary objects on a road or a road side such as small, two-wheeled vehicles,
bicycles, pedestrians, animals, and shopping carts.

Vehicle shapes which do not reflect radar waves well such as empty trailers with a low
vehicle height and sports cars.
Vehicles are shipped with the direction of the radar sensors (rear) adjusted for each
vehicle to a loaded vehicle condition so that the radar sensors (rear) detect approaching
vehicles correctly. If the direction of the radar sensors (rear) has deviated for some
reason, have the vehicle inspected at an Authorized Mazda Dealer.
For repairs or replacement of the radar sensors (rear), or bumper repairs, paintwork, and
replacement near the radar sensors, consult an Authorized Mazda Dealer.
Turn off the system while pulling a trailer or while an accessory such as a bicycle carrier
is installed to the rear of the vehicle. Otherwise, the radio waves emitted by the radar will
be blocked causing the system to not operate normally.
The radar sensors are regulated by the relevant radio wave laws of the country in which
the vehicle is driven. If the vehicle is driven abroad, authorization from the country in
which the vehicle is driven may be required.
