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)
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
it. If the Forward Sensing Camera (FSC) is severely hit or if there are cracks or damage
caused by flying gravel or debris in the area around it, stop using the following systems
and consult an Authorized Mazda Dealer.

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.

Radar Sensor (Front)*
Your vehicle is equipped with a radar sensor (front).
The following systems also use the radar sensor (front).
•Distance Recognition Support System (DRSS)
•Mazda Radar Cruise Control with S top & Go function (MRCC with Stop & Go function)
•Smart Brake Support (SBS)
The radar sensor (front) function s by detecting the radio waves reflected off a vehicle ahead
or an obstruction sent from the radar sensor.
The radar sensor (front) is m ounted behind the front emblem.
Radar sensor (front)
If “Front Radar Sensor Blocked” is displayed in the multi-infor mation display of the
instrument cluster, clean the area around the radar sensor (fro nt).
CAUTION
Heed the following precautions to assure correct operation of each system.
Do not adhere stickers (including transparent stickers) to the surface of the radiator grille
and front emblem in and around the radar sensor (front), and do not replace the radiator
grille and front emblem with any product that is not a genuine product designed for use
with the radar sensor (front).
The radar sensor (front) includes a function for detecting soiling of the radar sensor's front
surface and informing the driver, however, depending on the conditions, it may require
time to detect or it may not detect plastic shopping bags, ice or snow. If this occurs, the
system may not operate correctly, therefore al ways keep the radar sensor (front) clean.
Do not install a grille guard.
If the front part of the vehicle has been dama ged in a vehicle accident, the position of the
