Distance Recognition Support System (DRSS) *
The Distance Recognition Support System (DRSS) measures the distance between your
vehicle and a vehicle ahead using a radar sensor (front) while the vehicle speed is 30 km/h
or faster (19 mph or faster), and indicates a recommended distance to maintain between the
vehicles. Furthermore, if your vehicle approaches a vehicle ahead more closely than the
appropriate distance to maintain between the vehicles, the vehicle-ahead indication in the
active driving display is fl ashed to advise the driver to keep a safer distance from the vehicle
ahead.
WARNING
Do not rely completely on the Distance Recognition Support System (DRSS) and always
drive carefully:
The Distance Recognition Support System (DRSS) provides advice for safer driving and
notifi es the driver of a recommended, safer distance to maintain with a vehicle ahead.
The ability to detect a vehicle ahead is limited depending on the type of vehicle ahead,
the weather conditions, and the traffi c conditions. Therefore, if the accelerator and
brake pedals are not operated correctly it could lead to 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.
NOTE
  The Distance Recognition Support System (DRSS) operates when all of the following
conditions are met:
 


 The ignition is switched ON. 

 The Distance Recognition Support System (DRSS) is on.



 The selector lever is in a position other than reverse (R).



 The vehicle speed is 30 km/h or faster (19 mph or faster). 

 The objects which activate the system are 4-wheeled vehicles. 
 The Distance Recognition Support System (DRSS) may also operate in the presence of
motorcycles and bicycles.
  The Distance Recognition Support System (DRSS) may not operate normally under
the following conditions:
 


 The Dynamic Stability Control (DSC) has a malfunction.

WARNING
Always check the surrounding area visually before actually putting the vehicle in
reverse:
The system is only designed to assist you in checking for vehicles at the rear when
putting the vehicle in reverse. Due to certain limitations with the operation of this
system, the Blind Spot Monitoring (BSM) warning light may not fl ash or it might be
delayed even though a vehicle is behind your vehicle. Always make it your responsibility
as a driver to check the rear.
NOTE
  In the following cases, the Blind Spot Monitoring (BSM) OFF indicator light turns
on and operation of the system is stopped. If the Blind Spot Monitoring (BSM) OFF
indicator light remains illuminated, have the vehicle inspected at an Authorised Mazda

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 to detect the distance to a vehicle ahead,
which frees the driver 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.
The possible vehicle speed setting ranges are as follows:
 


(European models)
 About 30 km/h (19 mph) to 200 km/h (124 mph)



(Except European models)
 About 30 km/h (19 mph) to 145 km/h (90 mph)
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))

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

 
 Do not disassemble the laser sensor (front) .


 
 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 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 (front) , the system may
operate unnecessarily and cause an unexpected accident.
  Refer to Stopping The Smart City Brake Support (SCBS) System Operation on
page 4-143 .
 

 
 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.
