Extended vehicle width lines and dis‐
tance guide lines (red/blue)These guide lines indicate the
approximate width of the vehi‐
cle and distance to a point measur ed from the rear of the vehi‐
cle (from the end of the bumper).
The red lines indicate the poin ts up to about 0.5 m from the
rear end of the bumper.
The blue lines indicate the po ints from about 0.5 m (20 in)
and up to 2 m (79 in) from the rear end of the bumper.
Blind Spot Monitoring (BSM) warning

ated.
For details, refer to Rear Cross Traffic Alert (RCTA).
Refer to Rear Cross Traffic Alert (RCTA) on page 4-138.
NOTE
The parking sensor obstruction detection indication does not display. Switch the screen
display to the top view/rear view display if the parking sensor warning sound is activated.
The rear wide view screen displays the image at the rear of the vehicle at a wide angle
and corrects the image to help detect approaching obstructions from the side. Therefore, it
differs from the actual view.
▼ Margin of Error Between Road Surf
ace on Screen and Actual Road Surface
There might be some margin of err or between the road surface appearing on the screen and
the actual road surface. A margi n of error in the perceived distance could lead to an
accident, therefore be aware of the following conditions which can more easily produce
errors in the perceived distance.
The vehicle tilts due to weight of passengers and cargo.
If the vehicle is tilted, obstructions picked up by a camera ca n appear farther or closer than
the actual distance from the vehicle.

Forward Sensing Camera (FSC)*
Your vehicle is equipped with a Forward Sensing Camera (FSC). The Forward Sensing
Camera (FSC) is positioned near t he rearview mirror and used by the following systems.
High Beam Control System (HBC)
Lane-keep Assist System (LAS) & Lane Departure Warning System ( LDWS)
Traffic Sign Recognition System (TSR)
Advanced Smart City Brake Support (Advanced SCBS)
Smart City Brake Support (SCBS)
Mazda Radar Cruise Control with Stop & Go function (MRCC with S top & Go function)
Smart Brake Support (SBS)
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 distance in w hich the Forward Sensing
Camera (FSC) can detect objects varies depending on the surroun ding conditions.
WA R N I N G
Do not modify the suspension:
If the vehicle height or inclination is changed, the system will not be able to correctly detect
vehicles ahead. This will result in the system not operating normally or mistakenly operating,
which could cause a serious accident.
CAUTION
Do not apply accessories, stickers or film to the windshield near the Forward Sensing
Camera (FSC).
If the area in front of the Forward Sensing Came ra (FSC) lens is obstructed, it will cause the
system to not operate correctly. Consequently, each system may not operate normally
which could lead to an unexpected accident.

Do not disassemble or modify the Forward Sensing Camera (FSC).
Disassembly or modification of the Forward Sensing Camera (FSC) will cause a malfunction
or mistaken operation. Consequently, each sy stem may not operate normally which could
lead to an unexpected accident.
Heed the following cautions to assure the correct operation of the Forward Sensing Camera
(FSC).
Be careful not to scratch the Forward Sensing Camera (FSC) lens or allow it to get dirty.
Do not remove the Forward Sensing Camera (FSC) cover.
Do not place objects on the dashboard which reflect light.
Always keep the windshield glass around the camera clean by removing dirt or fogging.
Use the windshield defroster to remove fogging on the windshield.
Consult an Authorized Mazda Dealer regardi ng cleaning the interior side of the
windshield around the Forw ard Sensing Camera (FSC).
Consult an Authorized Mazda Dealer before performing repairs around the Forward
Sensing Camera (FSC).
The Forward Sensing Camera (FSC) is installe d to the windshield. Consult an Authorized
Mazda Dealer for windshield repair and replacement.
When cleaning the wind shield, do not allow glass cleaners or similar cleaning fluids to
get on the Forward Sensing Camera (FSC) le ns. In addition, do not touch the Forward
Sensing Camera (FSC) lens.
When performing repairs around the rearv iew mirror, consult an Authorized Mazda
Dealer.
Consult an Authorized Mazda Dealer regarding cleaning of the camera lens.
Do not hit or apply strong force to the Forward Sensing Camera (FSC) or the area around

The direction in which the Forward Sensing Camera (FSC) is pointed has been
finely
adjusted. Do not change the installation posi tion of the Forward Sensing Camera (FSC) or
remove it. Otherwise, it could result in damage or malfunction.
Always use tires for all wheels that are of the specified size, and the same manufacturer,
brand, and tread pattern. In addition, do no t use tires with significantly different wear
patterns on the same vehicle as the system may not operate normally.

The Forward Sensing Camera (FSC) includes a function for detecting a soiled windshield
and informing the driver, however, depending on the conditions, it may not detect plastic
shopping bags, ice or snow on the windshield . In such cases, the system cannot accurately
determine a vehicle ahead and may not be able to operate normally. Always drive carefully
and pay attention to the road ahead.
NOTE
In the following cases, the Forward Sensing Camera (FSC) cannot detect target objects
correctly, and each system may be unable to operate normally.
The height of the vehicle ahead is low.
You drive your vehicle at the same speed as the vehicle ahead.
Headlights are not turned on during the night or when going through a tunnel.
In the following cases, the Forward Sensing Camera (FSC) may not be able to detect
