Forward Sensing Camera(FSC)
*
▼Forward Sensing Camera (FSC)
Your vehicle is equipped with a Forward
Sensing Camera (FSC). The Forward
Sensing Camera (FSC) is positioned near
the rearview mirro
r and used by the
following systems.
High Beam Control System (HBC)
Lane Departure Warning System
(LDWS)
Traffic Sign Recognition System (TSR)
Distance & Speed Alert (DSA)
Driver Attention Alert (DAA)
Driver Monitoring (DM)

1. 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 which the
Forward Sensing Camera (FSC) can detect
objects varies depending on the
surrounding 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 Camera (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 system 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).

(FSC) lens.
 When performing repairs around the
rearview 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.

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.
