*Some models.
Smart Brake Support (SBS) *
Smart Brake Support (SBS) is a system which alerts the driver of a possible collision using
an indicator and warning sound in the instrument cluster while the vehicle is being driven at
about 15 km/h or faster (10 mph or faster) and the system's radar sensor (front) determines
that your vehicle may hit a vehicle ahead. Furthermore, if the radar sensor (front) 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 operate more quickly to
assist the driver (vehicles with brake À uid pre-¿ ll).
WARNING
Do not rely completely on the Smart Brake Support (SBS) system and always drive
carefully:
The Smart Brake Support (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 traffi c 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
If the vehicle is towed or you are towing something, switch the Smart Brake Support (SBS)
system off to prevent a mistaken operation.

CAUTION
 


¾ Do not apply accessories, stickers or fi lm 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.
 


¾ Do not disassemble or modify the Forward Sensing Camera (FSC).
 Disassembly or modifi cation 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.
 


¾ Heed the following cautions to assure the correct operation of the Forward Sensing Camera
(FSC).
 


¾ The direction of the Forward Sensing Camera (FSC) has been fi nely adjusted, therefore
do not change the installation position or remove the Forward Sensing Camera (FSC).
 


¾ Be careful not to scratch the Forward Sensing Camera (FSC) lens or allow it to get dirty.



¾ Do not remove the Forward Sensing Camera (FSC) cover.



¾ Do not place objects on the dashboard which refl ect light.



¾ Always keep the windshield glass around the camera clean by removing dirt or fogging.
Use the windshield defroster to remove fogging on the windshield.
 


¾ Consult an Authorized Mazda Dealer regarding cleaning the interior side of the
windshield around the Forward Sensing Camera (FSC).
 


¾ Consult an Authorized Mazda Dealer before performing repairs around the Forward
Sensing Camera (FSC).
 


¾ The Forward Sensing Camera (FSC) is installed to the windshield. Consult an Authorized
Mazda Dealer for windshield repair and replacement.
 


¾ When performing repairs around the rearview mirror, consult an Authorized Mazda
Dealer.
 


¾ Do not hit or apply strong force to the Forward Sensing Camera (FSC) or the area around
it. If strong force is applied, stop using the Lane Departure Warning System (LDWS), the
High Beam Control System (HBC), and the Smart Brake Support (SBS) and consult an
Authorized Mazda Dealer.
 


¾ The direction in which the Forward Sensing Camera (FSC) is pointed has been fi nely
adjusted. Do not change the installation position of the Forward Sensing Camera (FSC)
or remove it. Otherwise, it could result in damage or malfunction.

Radar Sensor (Front) *
Your vehicle is equipped with a radar sensor (front).
The following systems also use the radar sensor (front).
 


y Mazda Radar Cruise Control (MRCC)



y Distance Recognition Support System (DRSS)



y Smart Brake Support (SBS)
The radar sensor (front) functions by detecting the radio waves reÀ ected 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 the Smart Brake Support/Smart City Brake Support (SBS/SCBS) Warning Light (amber)
is illuminated, the area around the radar sensor may be dirty. Refer to “Warning Guidance”
in the center display (Type B audio).

y Under the following conditions, the radar sensor (front) may not be able to detect
vehicles ahead or obstructions correctly and each system may not operate normally.
 


y The rear surface of a vehicle ahead does not reÀ ect radio waves effectively, such as
an unloaded trailer or an automobile with a loading platform covered by a soft top,
vehicles with a hard plastic tailgate, and round-shaped vehicles.
 


y Vehicles ahead with low vehicle height and thus less area for reÀ ecting radio waves.



y Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its
tires and onto your windshield.
 


y The luggage compartment is loaded with heavy objects or the rear passenger seats are
occupied.
 


y Ice, snow, or soiling is on the front surface of the front emblem.



y During inclement weather such as rain, snow, or sand storms.



y When driving near facilities or objects emitting strong radio waves. 



y Under the following conditions, the radar sensor (front) may not be able to detect
vehicles ahead or obstructions.
 


y The beginning and end of a curve.



y Roads with continuous curves.



y Narrow lane roads due to road construction or lane closures.



y The vehicle ahead enters the radar sensor's blind spot.



y The vehicle ahead is running abnormally due to accident or vehicle damage.



y Roads with repeated up and down slopes



y Driving on poor roads or unpaved roads.



y The distance between your vehicle and the vehicle ahead is extremely short.



y A vehicle suddenly comes close such as by cutting into the lane. 



y To prevent incorrect operation of the system, use tires of the same speci¿ ed size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use tires
with signi¿ cantly different wear patterns or tire pressures on the same vehicle (Including
the temporary spare tire).
 


y If the battery power is weak, the system may not operate correctly.



y If the vehicle is driven on a road with little traf¿ c and few vehicles ahead or obstructions
for the radar sensor (front) to detect, the sensor detects that the radar sensor (front) is
dirty and the Smart Brake Support/Smart City Brake Support (SBS/SCBS) Warning Light
(amber) may be temporarily turned on. However, it does not indicate a malfunction.

switch. The cruise main indicator light
(Amber) illuminates.
To deactivate the system, press the OFF
switch.
The cruise main indicator light (Amber)
turns off.
WARNING
Always turn off the cruise control system
when it is not in use:
Leaving the cruise control system in an
activation-ready state while the cruise
control is not in use is dangerous as
the cruise control could unexpectedly
activate if the activation button is
accidentally pressed, and result in loss
of vehicle control and an accident.

N O T E
When the ignition is switched OFF, the
system status before it was turned off is
maintained. For example, if the ignition
is switched OFF with the cruise control
system operable, the system will be
operable when the ignition is switched ON
the next time.

To Set Speed
1. Activate the cruise control system
by pressing the ON switch. The
cruise main indicator light (Amber)
illuminates.
2. Accelerate to the desired speed, which
must be more than 25 km/h (16 mph).
3. Set the cruise control by pressing the
SET
or SET switch at the desired
speed. The cruise control is set at the
moment the SET
or SET switch is
pressed. Release the accelerator pedal
simultaneously. The cruise set indicator
light (Green) illuminates.

When Driving
Tire Pressure Monitoring System
*Some models.
Tire Pressure Monitoring System *
The Tire Pressure Monitoring System (TPMS) monitors the air pressure of all four tires. If
the air pressure of one or more tires is too low, the system warns the driver by indicating the
tire pressure monitoring system warning light in the instrument cluster and operating a beep
sound. The system monitors the tire pressures indirectly using the data sent from the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the speci¿ ed
tire pressure (value on the tire pressure label). Follow the procedure and perform the
initialization.
Refer to Tire Pressure Monitoring System Initialization on page 4-129 .
The warning light À ashes when the system has a malfunction.
Refer to Warning Lights on page 4-25 .
