Smart Brake Support
[Rear Crossing] (SBS -RC)
*
▼ Smart Brake Support [Rear
Crossing]
(SBS-RC)
The SBS -RC is a system designed to
assist the driver in avoiding collisions
and to reduce damage in the event of
a collision by applying the brakes if
there is the possibility of collision with
a vehicle approaching from the rear
while you are reversing out of parking
space.
The SBS -RC system detects vehicles
approaching from the rear left and
right sides of the vehicle, and the rear
of the vehicle while the vehicle is being
reversed out of a parking space, the
system reduces damage in the event of
a collision by operating the brake
control when the system determines
that a collision is unavoidable.
SBS -RC operation
1. The
SBS-RC system operates when
the shift lever (manual
transmission) or the selector lever
(automatic transmission) is shifted
to the reverse (R) position.
2. If there is the possibility of a
collision with an approaching
vehicle, the SBS-RC system applies
brake and displays “BRAKE!” on the
active driving display and the
multi-information display.
WARNING
Always check the surrounding area
visually before actually putting the
vehicle in reverse:
The system is only designed to assist
you in backing out of the lot when
putting the vehicle in reverse. Due to
certain limitations with the operation
of this system, the SBS -RC system may
not operate brake or it might be
delayed even though a vehicle is
behind your vehicle. Always make it
your responsibility as a driver to check
the rear.
Do not rely completely on the SBS -RC
system:
 The
SBS-RC system is only designed
to reduce damage in the event of a
collision. Over reliance on the system
leading to the accelerator pedal or
brake pedal being mistakenly
operated could result in an accident.
 The
SBS-RC system operates in
response to a vehicle. The system
does not operate in response to
obstructions such as a wall,
pedestrians, or animals.

Mazda3_8JM2-EA -20H_Edition1_new 2020-7-10 17:21:34

To assure the correct operation of the
SBS-RC, heed the following cautions.
 Do not apply a sticker to a rear radar
and rear camera. Otherwise, the rear
radar and rear camera may not be
able to detect vehicles or
obstructions which could result in an
accident.
 Do not disassemble a rear radar and
rear camera.
 If cracks or damage caused by flying
gravel or debris is visible around a
rear radar and rear camera, stop
using the SBS -RC system
immediately and have your vehicle
inspected by an Authorized Mazda
Dealer. If the vehicle continues to be
driven with cracks or scratch marks
left around an ultrasonic sensor, the
system may operate unnecessarily
and cause an unexpected accident.
Refer to Stopping the Smart Brake
Support [Rear Crossing] (SBS -RC)
System Operation on page 4-168.
 Consult an Authorized Mazda Dealer
for rear bumper removal.
Do not modify the suspension:
If the vehicle height or inclination is
changed, the SBS -RC system may not
operate correctly because it cannot
detect obstructions correctly.Do not apply a strong force to a rear
radar and rear camera:
When washing the vehicle, do not
spray highly pressurized water against a
rear radar and rear camera, or rub it
strongly. In addition, do not hit the rear
bumper forcefully when loading and
unloading cargo. Otherwise, the
sensors may not detect obstructions
correctly which could cause the
SBS -RC system to not operate
normally, or it could operate
unnecessarily.
NOTE
The SBS -RC system will operate
under the following conditions.
The engine is running for 3 seconds
or more.
The shift lever (manual
transmission ve hicle) or the
selector lever (automatic
transmission vehicl e) is in the R
(reverse) position.
i-ACTIVSENSE warning indication/
warning light is not displayed in the
multi-information display.
The vehicle speed is under about
10 km/h (6 mph).
The vehicle speed of an
approaching vehicle is about 3
km/h (2 mph) or faster.
The SBS-R is not turned
off.The DSC is not malfunctioning.In the following cases, the
i-ACTIVSENSE warning indication/
warning light turns on and operation
of the system is stopped. If the
i-ACTIVSENSE warning indication/
warning light remains illuminated,
have the vehicle inspected at an
Authorized Mazda Dealer as soon as
possible.
Some problem with the system
including the SBS -RC system.

Tu r n off the SBS-RC system while
pulling a trailer or while an accessory
such as a bicycle carrier is installed to
the rear of the vehicle. Otherwise,
the radio waves emitted by the radar
will be blocked causing the system to
not operate normally.
In the following cases, a rear radar
and rear camera may detect
something as a target obstruction
which could cause the SBS -RC
system to operate.
There are hanging curtains, gate
poles such as at toll gates and
railroad crossing.
When traveling near objects such
as foliage, barriers, vehicles, walls,
and fences along a road.
When driving off -road in areas
where there is grass and forage.
When passing through low gates,
narrow gates, car washing
machines, and tunnels.
A trailer is connected.When a rear-mounted bike rack
(towbar bike carrier) is installed.
(Manual transmission)

▼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
ffic Sign Recognition System (TSR)Distance & Speed Alert (DSA)Driver Attention Alert (DAA)Mazda Radar Cruise Control
(MRCC)
Mazda Radar Cruise Control with
Stop & Go function (MRCC with
Stop & Go function)
Lane-keep Assist System (LAS)Tra
ffic Jam Assist (TJA)Smart Brake Support (SBS)
1. Forward Sensing Camera (FSC)

The Forward Sensing Camera (FSC)
determines the conditions ahead of
the vehicle while traveling at night and
detects tra
ffic 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.
