Smart Brake Support(SBS)
*
The SBS system alerts the driver of a
possible collision us ing a display and
warning sound if the radar sensor (front)
and the Forward Sensing Camera (FSC)
determine that there is the possibility of a
collision with a vehicle ahead while the
vehicle is being driven at about 15 km/h or
faster (10 mph or faster). Furthermore, if
the radar sensor (front) and the Forward
Sensing Camera (FSC) determines that a
collision is unavoidable, the automatic
brake control is performed to reduce
damage in the event of a collision.
In addition, when the driver depresses the
brake pedal, the brakes are applied firmly
and quickly to assist. (Brake Assist (SBS
brake assist))
WARNING
Do not rely completely on the SBS system
and always drive carefully:
The SBS is designed to reduce damage in
the event of a collision, not avoid an
accident. The ability to detect an
obstruction is limited depending on the
obstruction, weather conditions, or traffic
conditions. Therefore, if the accelerator
pedal or brake pedal is mistakenly
operated it could result in an accident.
Always verify the safety of the surrounding
area and depress the brake pedal or
accelerator pedal while keeping a safer
distance from vehicles ahead or on-coming
vehicles.
CAUTION
In the following cases, turn the system off
to prevent a mis-operation:
 The vehicle is being towed or when
towing another vehicle.
 The vehicle is on a chassis roller.
 When driving on rough roads such as in
areas of dense grass or
off-road.
NOTE
The SBS system operates when all of the
following conditions are met:
The ignition is switched ON.
The SBS system is on.
The vehicle speed is about 15 km/h or
faster (10 mph or faster).
The relative speed between your
vehicle and the vehicle ahead is about
15 km/h or faster (10 mph or faster).
The Dynamic Stability Control (DSC)
is not operating.
The SBS system may not operate under
the following conditions:
If the vehicle is accelerated rapidly
and it comes close to a vehicle ahead.
The vehicle is driven at the same
speed as the vehicle ahead.
The accelerator pedal is depressed.
The brake pedal is depressed.
The steering wheel is being operated.
The selector lever is being operated.
The turn signal is being used.
When the vehicle ahead is not
equipped with taillights or the
taillights are turned off.

When warnings and messages, such
as a dirty windshield, related to the
Forward Sensing Camera (FSC) are
being displayed in the
multi-information display.
Although the objects which activate the
system are four-wheeled vehicles, the
radar sensor (front) could detect the
following objects, determine them to be
an obstruction, and operate the SBS
system.
Objects on the road at the entrance to
a curve (including guardrails and
snow banks).
A vehicle appears in the opposite lane
while cornering or rounding a curve.
When crossing a narrow bridge.
When passing under a low gate or
through a tunnel or narrow gate.
When entering an underground
parking area.
Metal objects, bumps, or protruding
objects on the road.
If you suddenly come close to a
vehicle ahead.
When driving in areas where there is
high grass or forage.
Two-wheeled vehicles such as
motorbikes or bicycles.
Pedestrians or non-metallic objects
such as standing trees.
If there is a problem with the SBS
system, a message is displayed in the
multi-information display. Check the
center display to verify the problem and
then have your vehicle inspected by an
Authorized Mazda Dealer.
Refer to Message Indicated on Display
on page 7-43.
▼Collision Warning
If there is the possibili
ty of a collision with
a vehicle ahead, the beep sounds
continuously and a warning is indicated in
the multi-information display and the
active driving display.
▼ Stopping The Smart Brake Support
(SBS) System Operation

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 Stop & Go function (MRCC with Stop & Go function)
Smart Brake Support (SBS)
The radar sensor (front) functions by detecting the radio waves reflected off a vehicle ahead
or an obstruction sent from the radar sensor.
The radar sensor (front) is mounted behind the front emblem.
Radar sensor (front)
If “Front Radar Sensor Blocked” is displa yed in the multi-information display of the
instrument cluster, clean the area around the radar sensor (front).
CAUTION
Heed the following precautions to assu re 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
radar sensor (front) may have moved. Stop the system immediately and always have the
vehicle inspected at an Authorized Mazda Dealer.

Under extremely hot or cold weather conditions.
The vehicle is driven on bumps, inclines, gravel, or grass covered roads.
Anything which generates ultrasound is near the vehicle, such as another vehicle's
horn, the engine sound of a motorcycle, the air brake sound of a large-sized vehicle, or
another vehicle's sensors.
The vehicle is driven in heavy rain or in road conditions causing water-splash.
A commercially-available fender pole or an antenna for a radio transmitter is installed
to the vehicle.
The vehicle is moving towards a tall or square curbstone.
An obstruction is too close to the sensor.
Obstructions under the bumper may not be detected. Obstructions that are lower than the
bumper or thin which may have been initially detected may no longer be detected as the
vehicle approaches more closely to the obstruction.
The following types of obstructions may not be detected:
Thin objects such as wire or rope
Things which absorb sonic waves easily such as cotton or snow
Angular shaped objects
Very tall objects, and those which are wide at the top
Small, short objects
Always have the system inspected at an Authorized Mazda Dealer if any shock is applied
to the bumpers, even in a minor accident. If the sensors are deviated, they cannot detect
obstructions.
(With front ultrasonic sensor and front ultrasonic corner sensor)
The system may have a malfunction if the beep does not operate or the indicator light
does not illuminate when the parking sensor switch is turned on. Consult an Authorized
Mazda Dealer.
(Without front ultrasonic sensor and front ultrasonic corner sensor)
The system may have a malfunction if the be ep does not operate. Consult an Authorized
Mazda Dealer.
(With front ultrasonic sensor and front ultrasonic corner sensor)
The system may have a malfunction if the beep sound which indicates a system
malfunction is heard and the i ndicator light flashes. Consult an Authorized Mazda Dealer.
The beeper which indicates a system malf unction may not be heard if the ambient
temperature is extremely cold, or mud, ice, or snow adheres to the sensor area. Remove
any foreign material from the sensor area.
