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
y The Distance Recognition Support System (DRSS) operates when all of the following
conditions are met:
y The ignition is switched ON.
y The Distance Recognition Support System (DRSS) is on.
y The selector lever is in a position other than reverse (R).
y The vehicle speed is 30 km/h or faster (19 mph or faster).
y The objects which activate the system are 4-wheeled vehicles.
y The Distance Recognition Support System (DRSS) may also operate in the presence of
motorcycles and bicycles.
y The Distance Recognition Support System (DRSS) may not operate normally under the
following conditions:
y The Dynamic Stability Control (DSC) has a malfunction.
y The vehicle ahead is traveling at an extremely slow speed.
y The system does not operate with the following objects:
y Vehicles approaching in the opposite direction.
y Stationary objects (stopped vehicles, obstructions)

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.

Do not rely completely on the Smart City Brake Support (SCBS) system:
¾ 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.
¾ 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.
¾ 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.
¾
Do not apply stickers to the surface of the windshield 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.
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
