Forward Sensing Camera(FSC)
*
The Forward Sensing Camera (FSC)
determines the conditions ahead of
the vehicle and detects the white
(yellow) lines on the traffic lane.
1. Forward Sensing Camera (FSC)

The following systems utilize the
Forward Sensing Camera (FSC).
High Beam Control System (HBC)Lane Departure Warning System
(LDWS)
Traffic Sign Recognition System (TSR)Distance & Speed Alert (DSA)Driver Attention Alert (DAA)Mazda Radar Cruise Control
(MRCC)
Cruising & Traffic Support (CTS)Lane-keep Assist System (LAS)Emergency Lane Keeping (ELK)Smart Brake Support (SBS) forward
drive detection
WARNING
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
Heed the following cautions to operate
the system correctly.
Do not hit or apply strong force to
the Forward Sensing Camera (FSC)
or the area around it. If the Forward
Sensing Camera (FSC) received a
strong impact, stop using the
following systems and consult an
Authorized Mazda Dealer.
 High Beam Control System (HBC)
 Lane Departure Warning System
(LDWS)
 Traffic Sign Recognition System
(TSR)
 Distance & Speed Alert (DSA)
 Driver Attention Alert (DAA)
 Mazda Radar Cruise Control
(MRCC)
 Cruising & Traffic Support (CTS)
 Lane-keep Assist System (LAS)
 Emergency Lane Keeping (ELK)
 Smart Brake Support (SBS) forward
drive detection
 Do not remove the Forward Sensing
Camera (FSC) cover.
 Be careful not to scratch the Forward
Sensing Camera (FSC) lens or allow
it to get dirty. Also, do not take the
camera apart. Otherwise, it may
cause a malfunction or
mis-operation.
 The direction of the Forward Sensing
Camera (FSC) has been
finely
adjusted, therefore do not change
the installation position or remove
the Forward Sensing Camera (FSC).
Otherwise, it may cause a
malfunction or mis-operation.
 Consult an Authorized Mazda Dealer
regarding cleaning of the camera

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
Camera (FSC) lens is obstructed, it
will cause the system to not operate
correctly even if it is transparent.
 Always keep the windshield glass
around the Forward Sensing Camera
(FSC) clean by removing dirt or
fogging. If the windshield is fogged,
press the windshield defroster
switch.
 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, water or snow on the
windshield. In such cases, the system
cannot accurately determine a
vehicle or obstruction in front and
may not be able to operate normally.
Always drive carefully and pay
attention to the road ahead.
 When cleaning the windshield, do
not allow glass cleaners or similar
cleaning fluids to get on the Forward
Sensing Camera (FSC) lens. In
addition, do not touch the Forward
Sensing Camera (FSC) lens.
 Consult an Authorized Mazda Dealer
regarding cleaning the interior side of
the windshield around the Forward
Sensing Camera (FSC).
 If there are cracks or damage caused
by flying gravel or debris on the
windshield, always have the
windshield replaced. Consult an
Authorized Mazda Dealer before
replacing the windshield.
 Consult an Authorized Mazda Dealer
before doing repairs around the
Forward Sensing Camera (FSC).When doing repairs around the
rearview mirror, consult an
Authorized Mazda Dealer.
 Always use tires of the specified size
and the same manufacturer, brand,
and tread pattern on all 4 wheels. In
addition, do not use tires with
significantly different wear patterns
or tire pressures on the same vehicle
(including temporary spare tire).
NOTE
If the Forward Sensing Camera (FSC)
does not function normally due to
fog or the vehicle being driven
towards the sun, the functions
related to the Forward Sensing
Camera (FSC) are temporarily
stopped. In this case, the following
warning indications turn on.
However, this does not indicate a
problem.
HBC warning indicationi-ACTIVSENSE warning indicationSBS OFF indicationIf the Forward Sensing Camera (FSC)
does not function normally due to
