Mazda Radar Cruise Control (MRCC) *
The Mazda Radar Cruise Control (MRCC) system is designed to maintain headway control *1
according to the vehicle speed using a radar sensor (front) to detect the distance to a vehicle
ahead, and by presetting the vehicle speed between 30 km/h (19 mph) and 145 km/h (90
mph), the driver is freed from having to constantly use the accelerator or brake pedals.
*1 Headway Control: Control of the distance between your vehicle and the vehicle ahead
detected by the Mazda Radar Cruise Control (MRCC) system.
Additionally, if your vehicle starts closing in on the vehicle ahead because, for example, the
vehicle ahead brakes suddenly, a warning sound and a warning indication in the display are
activated simultaneously to alert you to maintain a suffi cient distance between the vehicles.
Use the Mazda Radar Cruise Control (MRCC) system on expressways and other highways
which do not require a lot of repeated acceleration and deceleration.

Smart City Brake Support (SCBS) *
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
(front) 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 fi rmly and quickly to
assist. (Brake Assist (SCBS brake assist))
Laser sensor (front)
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.

(including transparent stickers). Otherwise, the laser sensor (front) may not be able
to detect vehicles ahead which could result in an accident.
 

¾
 Do not apply coating agent to the windshield. Otherwise, the laser sensor (front)
may not be able to detect vehicles or obstructions in front which could result in an
accident.
 

¾
 Do not disassemble the laser sensor (front) .


¾
 If cracks or damage caused by fl ying gravel or debris is visible near the laser sensor
(front) , 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
(front) , the system may operate unnecessarily and cause an unexpected accident.
  Refer to Stopping The Smart City Brake Support (SCBS) System Operation on page
4-108 .
 

¾
 When 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

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.
