Smart City Brake Support [Forward] (SCBS F)

*

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

¿ rmly 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 tyre 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:

The 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.

The 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.

The 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.

Do not apply stickers to the surface of the windscreen 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.

Do not apply coating agent to the windscreen. Otherwise, the laser sensor may

not be able to detect vehicles or obstructions in front which could result in an
accident.

Do not disassemble the laser sensor.

If cracks or damage caused by

À ying 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 expert repairer, we recommend an Authorised
Mazda Repairer. If the vehicle continues to be driven with cracks or scratch marks
left on the windscreen 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 4-160 .

When replacing the windscreen wipers or windscreen, consult an expert repairer,

we recommend an Authorised Mazda Repairer.

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.

i-ACTIVSENSE

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.
Refer to the Stopping the Smart City Brake Support (SCBS) System Operation on page
4-160 on how to turn off the Smart City Brake Support (SCBS) system.

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 speci

¿ ed size, and the same

manufacturer, brand, and tread pattern. In addition, do not use tyres with signi

¿ cantly

different wear patterns on the same vehicle as the Smart City Brake Support (SCBS)
system may not operate normally.

The laser sensor 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.

Smart Brake Support (SBS)

*

The Smart Brake Support (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 performed to reduce damage in the event of a
collision.
In addition, when the driver depresses the brake pedal, the brakes are applied

¿ rmly and

quickly to assist. (Brake Assist (SBS brake assist))

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 traf

¿ 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
