WARNING
Turn off the Smart City Brake Support (SCBS) when the vehicle is running on a chassis
roller or being towed:
Turn off the Smart City Brake Support (SCBS) system to prevent mistaken operation
when the vehicle is running on a chassis roller or being towed. See the next page on
how to turn off the Smart City Brake Support (SCBS).
Refer to Stopping The Smart City Brake Support (SCBS) System Operation on page
4-143 .
CAUTION
  When driving off-road in areas where there is grass or forage, it is recommended that
the Smart City Brake Support (SCBS) system be turned off.
  Always use tyres for all wheels that are of the specifi ed size, and the same
manufacturer, brand, and tread pattern. In addition, do not use tyres with signifi cantly
different wear patterns on the same vehicle as the Smart City Brake Support (SCBS)
system may not operate normally.
  The laser sensor (front) includes a function for detecting a soiled windscreen and
informing the driver, however, depending on the conditions, it may not detect plastic
shopping bags, ice or snow on the windscreen. In such cases, the system cannot
accurately determine a vehicle ahead and may not be able to operate normally. Always
drive carefully and pay attention to the road ahead.
NOTE
  The Smart City Brake Support (SCBS) system will not operate if the driver is
deliberately performing driving operations (accelerator pedal and steering wheel).
  The Smart City Brake Support (SCBS) system will operate under the following
conditions.
 


 The engine is running.



 The Smart City Brake Support (SCBS) warning light (amber) does not illuminate.



 The vehicle speed is between about 4 to 30 km/h (2 to 18 mph).



 The Smart City Brake Support (SCBS) system is not turned off.



 The DSC is not malfunctioning.

When Driving
i-ACTIVSENSE
NOTE
  The Smart City Brake Support (SCBS) detects a vehicle ahead by emitting a near-
infrared laser beam and receiving the beam refl ected off the refl ector of the vehicle
ahead, and then using it for the measurement. Consequently, the Smart City Brake
Support (SCBS) may not operate under the following conditions:
 


 Refl ection of the laser is poor due to the shape of the vehicle ahead.



 The vehicle ahead is signifi cantly dirty.



 Under bad weather condition, such as rain, fog and snow.



 The window washer is being used or the windscreen wipers are not used when it's
raining.
 


 The windscreen is dirty.



 The steering wheel is turned completely left or right, or the vehicle is accelerated
rapidly and comes close to the vehicle ahead.
 


 Trucks with low loading platforms and vehicles with an extremely low or high
profi le.




 Vehicles with certain shapes such as a vehicle carrier. 

 Under the following conditions, the Smart City Brake Support (SCBS) system may not
operate normally.
 


 Heavy luggage is loaded in the luggage compartment or on the rear seat.



 If there is the possibility of partial contact with a vehicle ahead.



 When driving on continuously curving roads, and entering and exiting exits.



 Elongated luggage or cargo is loaded onto installed roof rails and covers the laser
sensor (front) .
 


 Exhaust gas from the vehicle in front, sand, snow, and water vapour rising from
manholes and grating, and water splashed into the air.
 


 When towing a malfunctioning vehicle.



 When driving with tyres having signifi cantly different wear. 

 In the following cases, the laser sensor (front) may inadvertently determine that there
is a vehicle ahead and the Smart City Brake Support (SCBS) system may operate.
 


 Objects on the road at the entrance to a curve.



 Vehicles passing in the opposite lane while making a curve.



 Metal objects, bumps, or protruding objects on the road.



 When passing through a toll gate equipped with a bar.



 When passing under a vinyl curtain or fl ag.



 Plastic objects such as pylons.



 Two-wheeled vehicles, pedestrians, animals or standing trees. 

(Manual transaxle) If the vehicle is stopped by the SCBS operation and the clutch pedal is not depressed,
the engine stops.

When Driving
i-ACTIVSENSE
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 fl uid pre-fi 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.

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)



 Smart Brake Support (SBS)

4–149
When Driving
i-ACTIVSENSE
CAUTION
  Do not apply accessories, stickers or fi lm to the windscreen 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 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.
  Heed the following cautions to assure the correct operation of the Forward Sensing
Camera (FSC).
 


 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).
 


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


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



 Do not place objects on the instrument panel which refl ect light.



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


 Consult an expert repairer, we recommend an Authorised Mazda Repairer regarding
cleaning the interior side of the windscreen around the Forward Sensing Camera
(FSC).
 


 Consult an expert repairer, we recommend an Authorised Mazda Repairer before
performing repairs around the Forward Sensing Camera (FSC).
 


 The Forward Sensing Camera (FSC) is installed to the windscreen. Consult an expert
repairer, we recommend an Authorised Mazda Repairer for windscreen repair and
replacement.
 


 When performing repairs around the rearview mirror, consult an expert repairer, we
recommend an Authorised Mazda Repairer.
 


 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 expert repairer, we recommend an Authorised Mazda Repairer.
 


 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.
