Smart City Brake Support (SCBS)í
The Smart City Brake Support (SCBS) system is designed to reduce damage in the event of
a collision by operating the brake control (SCBS brake) when the system's laser sensor
detects a vehicle ahead and determines that a collision with a vehicle ahead is unavoidable.
It may also be possible to avoid a collision if the relative speed between your vehicle and a
vehicle ahead is less than about 20 km/h (12 mph).
In addition, when the driver depresses the brake pedal while the system is in the operation
range at about 4 to 30 km/h (2 to 18 mph), the brakes are applied firmly and quickly to
assist. (Brake Assist (SCBS brake assist))

WARNING
Do not rely on the Smart City Brake Support System (SCBS) as a substitute for safer
driving:
The Smart City Brake Support (SCBS) system cannot compensate for unsafe and
reckless driving, excessive speed, tailgating (following another vehicle too closely),
and driving on slippery roads such as wet, snowy, and icy roads (reduced tire friction
and road contact because of water on the road surface). You can still have an
accident.

Do not rely completely on the Smart City Brake Support (SCBS) system:
ØThe Smart City Brake Support (SCBS) 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.
ØThe Smart City Brake Support (SCBS) is a system which operates in response to a
vehicle ahead. The system may not be able to detect or react to two-wheeled
vehicles or pedestrians.
ØThe laser sensor for the Smart City Brake Support (SCBS) system is installed near
the rearview mirror. To assure the correct operation of the Smart City Brake
Support (SCBS), heed the following cautions.
ØDo not apply stickers to the surface of the windshield near the laser sensor
(including transparent stickers). Otherwise, the laser sensor may not be able to
detect vehicles ahead which could result in an accident.
ØDo not apply coating agent to the windshield. Otherwise, the laser sensor may
not be able to detect vehicles in front which could result in an accident.
ØDo not disassemble the laser sensor.
ØIf cracks or damage caused by flying gravel or debris is visible near the laser
sensor, stop using the Smart City Brake Support (SCBS) system immediately
and have your vehicle inspected by an Authorized Mazda Dealer. If the vehicle
continues to be driven with cracks or scratch marks left on the windshield near
the laser sensor, the system may operate unnecessarily and cause an
unexpected accident.
Refer to Stopping the Smart City Brake Support (SCBS) System Operation on
page 4-130.
ØWhen replacing the windshield wipers or windshield, consult an Authorized
Mazda Dealer.
Do not modify the suspension:
If the vehicle height or inclination is changed, the system will not be able to correctly
detect vehicles ahead. This will result in the Smart City Brake Support (SCBS) system
not operating normally or mistakenly operating, which could cause a serious
accident.
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
4-130.

CAUTION
ØWhen 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.
ØAlways use tires for all wheels that are of the specified size, and the same
manufacturer, brand, and tread pattern. In addition, do not use tires with
significantly different wear patterns on the same vehicle as the Smart City Brake
Support (SCBS) system may not operate normally.
ØThe laser sensor 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.

lThe Smart City Brake Support (SCBS) system will operate under the following conditions.lThe engine is running.l“SCBS Forward malfunction”is not displayed in the multi-information display.lThe vehicle speed is between about 4 to 30 km/h (2 to 18 mph).lThe Smart City Brake Support (SCBS) system is not turned off.lThe DSC is not malfunctioning.lThe Smart City Brake Support (SCBS) detects a vehicle ahead by emitting a near-infrared laser
beam and receiving the beam reflected off the reflector of the vehicle ahead, and then using it for
the measurement. Consequently, the Smart City Brake Support (SCBS) may not operate under the

Smart Brake Support (SBS)í
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 determines that
your vehicle may hit a vehicle ahead. Furthermore, if the radar sensor 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 fluid pre-fill).
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 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.
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
Heed the following precautions to assure correct operation of each system.
ØDo not adhere stickers (including transparent stickers) to the surface of the
radiator grille and front emblem in and around the radar sensor (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).
ØThe radar sensor (front) includes a function for 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 shopping
bags, ice or snow. If this occurs, the system may not operate correctly, therefore
always keep the radar sensor (front) clean.
ØDo not install a grille guard.
ØIf the front part of the vehicle has been damaged in a vehicle accident, the
position of the radar sensor (front) may have moved. Stop the system immediately
and always have the vehicle inspected at an Authorized Mazda Dealer.
ØDo not use the front bumper to push other vehicles or obstructions such as when
pulling out of a parking space. Otherwise, the radar sensor (front) could be hit
and its position deviated.
ØDo not remove, disassemble, or modify the radar sensor (front).
ØFor repairs, replacement or paint work around the radar sensor (front), consult an
Authorized Mazda Dealer.
ØDo not modify the suspension. If the suspension are modified, the vehicle's posture
could change and the radar sensor (front) may not be able to correctly detect a
vehicle ahead or an obstruction.
