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 mirror
and used by the following systems.
High Beam Control System (HBC)Lane Departure Warning System
(LDWS)
Tra ffi c
Sign Recognition System (TSR)Distance & Speed Alert (DSA)Driver Attention Alert (DAA)Mazda Radar Cruise Control

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.
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

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).
 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.

damage caused by flying gravel or
debris in the area around it, stop
using the following systems and
consult an Authorized Mazda

 The direction in which the Forward
Sensing Camera (FSC) is pointed
has been finely adjusted. Do not
change the installation position 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 not 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.

Front Radar Sensor*
▼Front Radar Sensor
Your vehicle is equipped with a front
radar sensor.
The following systems also use the
front radar sensor.
Distance & Speed Alert (DSA)Mazda Radar Cruise Control
(MRCC)
Mazda Radar Cruise Control with
Stop & Go function (MRCC with
Stop & Go function)
Tra ffi c Ja m A s s i s t ( TJ A )Smart Brake Support (SBS)
The front radar sensor functions by
detecting the radio waves reflected off
a vehicle ahead or an obstruction sent
from the radar sensor.
The front radar sensor is mounted
behind the front emblem.
1. Front radar sensor

If “Safety and Driver Support Systems
Temporarily Disabled. Front Radar
Obscured. Drive Safely” is displayed on
the multi-information display of the
instrument cluster, clean the area
around the front radar sensor.
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 front radar sensor,
and do not replace the radiator grille
and front emblem with any product
that is not a genuine product
designed for use with the front radar
sensor.
 The front radar sensor 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
always keep the front radar sensor
clean.
 Do not install a grille guard.
 If the front part of the vehicle has
been damaged in a vehicle accident,
the position of the front radar sensor
may have moved. Stop the system
immediately and always have the
vehicle inspected at an Authorized
Mazda Dealer.
 Do not use the front bumper to push
other vehicles or obstructions such
as when pulling out of a parking
space. Otherwise, the front radar
sensor could be hit and its position
deviated.
 Do not remove, disassemble, or
modify the front radar sensor.
 For repairs, replacement or paint
work around the front radar sensor,
consult an Authorized Mazda Dealer.
 Do not modify the suspensions. If
the suspensions are modified, the
vehicle's posture could change and
the front radar sensor may not be
able to correctly detect a vehicle
ahead or an obstruction.
