Smart Brake Support
(SBS)
*
The SBS system alerts the driver of a
possible collision using 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 pe rformed 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))
WA R N I N G
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.

The following systems also use the radar sensor (front).
ï‚·Distance Recognition Support System (DRSS)
ï‚·Mazda Radar Cruise Control with Stop & Go function (MRCC with Stop & Go function)
ï‚·Smart Brake Support (SBS)
The radar sensor (front) functions by detecti ng the radio waves reflected off a vehicle ahead
or an obstruction sent from the radar sensor.
The radar sensor (front) is mo unted 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 sens or may be dirty. Refer to “Warning Guidance”
in the center display (Type B audio).
Refer to If a Warning Light Turns On or Flashes on page 7-26.
CAUTION
Heed the following precautions to a ssure correct operation of each system.
 Do not adhere stickers (including transparent st ickers) to the surface of the radiator grille
and front emblem in and around the radar sens or (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 fo r 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 sh opping 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

ï‚·If the vehicle is driven on a road with little traffic 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. Howe ver, it does not indicate a malfunction.
ï‚·The radar sensors are regulated by the relevant radio wave laws of the country in which
the vehicle is driven. If the vehicle is driven abroad, authorization from the country in
which the vehicle is driven may be required.

Tire Pressure Monitoring System*
The Tire Pressure Monitoring System (TPMS) monitors the pressure for each tire.
If tire pressure is too low in one or more tires, the system will inform the driver via the
warning light in the instrument cluster and by the warning beep sound.
Refer to Contact Authorized Mazda Dealer and Have Vehicle Inspected on page 7-29.
Refer to Taking Action on page 7-33.
Refer to Tire Inflation Pressure Warning Beep on page 7-44.

The tire pressure sensors installed on each wheel send tire pressure data by radio signal to
the receiver unit in the vehicle.
Tire pressure sensors
NOTE
When the ambient temperature is low due to seasonal changes, tire temperatures are also
lower. When the tire temperature decreases, the air pressure decreases as well. The TPMS
warning light may illumina te more frequently. Visually inspect the tires daily before driving,
and check tire pressures monthly with a tire pressure gauge. When checking tire pressures,
use of a digital tire pressure gauge is recommended.

TPMS does not alleviate your need to check the pressure and condition of all four tires
regularly.
CAUTION
 Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire in flation pressure label, you should determine
the proper tire inflation pressure for those tires.)
