Smart Brake Support(SBS)
*
▼Smart Brake Support (SBS)
The SBS alerts the driver of a possible
collision using the warning indications
in the display and a warning sound if
the front radar sensor and Forward
Sensing Camera (FSC) determine that
there is the possibility of a collision
with a vehicle ahead, pedestrian, or a
bicycle. Furthermore, if 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.
(Vehicles with Driver Monitoring
(DM))
When the SBS determines that the
driver is not paying attention to the
road using the driver monitoring
camera and it determines that there is
the possibility of a collision with an
obstruction, the SBS activates the
collision warning earlier than normal.
WARNING
Do not rely completely on the SBS:
The SBS is only designed to reduce
damage in the event of a collision.
The ability to detect obstructions is
limited depending on the obstructions,
weather conditions, or traffic
conditions. Over reliance on the
system leading to the accelerator pedal
or brake pedal being mistakenly
operated could result in an accident.
CAUTION
In the following cases, turn the system
o ff to prevent an unexpected
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 o ff-road.
See the next page on how to turn off
the system.
Refer to Stopping the Smart Brake
Support (SBS) System Operation on
page 4-160.

▼ Smart Brake Support [Rear]
(SBS
-R)
The SBS -R is a system which is
designed to reduce damage in the
event of a collision by operating the
brake control (SBS brake) when the
system’s sensors detect an obstruction
at the rear of the vehicle while driving
at a speed of about 2 to 8 km/h (2 to
4 mph) and the system determines that
a collision is unavoidable.
WARNING
Do not rely completely on the SBS -R
system:
 The
SBS-R 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.
 To assure the correct operation of
the SBS -R, heed the following
cautions.

CAUTION
Do not install any accessories within the detection ranges of the sensors. It may
a ff ect the system operation.
 Depending on the type of obstruction and the surrounding conditions, the
detection range of a sensor may narrow, or the sensors may not be able to detect
obstructions.

engine sound of a motorcycle, the air brake sound of a large-sized vehicle, or
another vehicle's sensors approaches the vehicle.
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, or a steep grade.An obstruction is too close to the sensor.The vehicle is moving towards an uneven wall or stairs.There are multiple obstructions.The vehicle is driven in a place with low ceilings.Obstructions under the bumper cannot be detected. Obstructions which are
lower than the sensor or thin may not be detected even though they were
detected once.
The following types of obstructions may not be detected:
Thin objects such as wire, rope or poles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

Operating Tips
▼Operating Tips
Operate the climate control system
with the engine running.
To prevent the battery from being
discharged, do not leave the fan
control switch on for a long period of
time with the ignition switched ON
when the engine is not running.
Clear all obstructions such as leaves,
snow and ice from the hood and the
air inlet in the cowl grille to improve
the system e
fficiency.
Use the climate control system to
defog the windows and dehumidify
the air.
The recirculate mode should be used
when driving through tunnels or
while in a
traffic jam, or when you
would like to shut o ff outside air for
quick cooling of the interior.
Use the outside air position for
ventilation or windshield defrosting.
If the vehicle has been parked in
direct sunlight during hot weather,
open the windows to let warm air
escape, then run the climate control
system.
(With A/C switch)
Run the air conditioner about 10
minutes at least once a month to
keep internal parts lubricated.
Have the air conditioner checked
before the weather gets hot. Lack of
refrigerant may make the air
conditioner less e fficient.
The refrigerant specifications are
indicated on a label attached to the
inside of the engine compartment. If
the wrong type of refrigerant is used,
it could result in a serious
malfunction of the air conditioner.
Consult a professional, government certi fied repairer for the inspection
or repair because a special device is
required for the air conditioner
maintenance.
For details, consult an Authorized
Mazda Dealer.
