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.
Refer to the Stopping the Smart City Brake Support (SCBS) System Operation on page
4-107 on how to turn off the Smart City Brake Support (SCBS) system.

CAUTION




¾ 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 .




¾ Always use tires for all wheels that are of the specifi ed size, and the same manufacturer,
brand, and tread pattern. In addition, do not use tires with signifi cantly diff erent wear
patterns on the same vehicle as the Smart City Brake Support (SCBS) system may not
operate normally.
 


¾ The laser sensor (front) includes a function for detecting a soiled windshield and informing
the driver, however, depending on the conditions, it may not detect plastic shopping bags,
ice or snow on the windshield. 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.

y The Smart City Brake Support (SCBS) detects a vehicle ahead by emitting a near-infrared
laser beam and receiving the beam reÀ ected off the reÀ 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:
 


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



y The vehicle ahead is signi¿ cantly dirty.



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



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


y The windshield is dirty.



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


y Trucks with low loading platforms and vehicles with an extremely low or high pro¿ le.



y Vehicles with certain shapes such as a vehicle carrier. 



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

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



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



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


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


y When towing a malfunctioning vehicle.



y When driving with tires having signi¿ cantly different wear. 



y 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.
 


y Objects on the road at the entrance to a curve.



y Vehicles passing in the opposite lane while making a curve.



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



y When passing through a toll gate equipped with a bar.



y When passing under a vinyl curtain or À ag.



y Plastic objects such as pylons.



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

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.
