i-ACTIVSENSE *
i-ACTIVSENSE is a collective term covering a series of advanced safety and driver support
systems which make use of a Forward Sensing Camera (FSC) and radar sensors. These
systems consist of active safety and pre-crash safety systems.
These systems are designed to assist the driver in safer driving by reducing the load on the
driver and helping to avert collisions or reduce their severity. However, because each system
has its limitations, always drive carefully and do not rely solely on the systems.
Active Safety Technology
Active Safety Technology supports safer driving by helping the driver to recognise potential
hazards and avert accidents.

Camera and Sensors
Forward Sensing Camera (FSC)
The Forward Sensing Camera (FSC) detects lane indications and recognises headlights, tail
lights and city lights during nighttime driving. The following systems also use the Forward
Sensing Camera (FSC).
High Beam Control System (HBC)
Adaptive LED Headlights (ALH)
Driver Attention Alert (DAA)
Lane Departure Warning System (LDWS)
Smart Brake Support (SBS)
The Forward Sensing Camera (FSC) is installed at the top of the windscreen near the
rearview mirror.
Refer to Forward Sensing Camera (FSC) on page 4-170 .
Radar sensor (front)
The radar sensor (front) functions by detecting the radio waves re À ected off a vehicle ahead
sent from the radar sensor. The following systems also use the radar sensor (front).
Distance Recognition Support System (DRSS)
Mazda Radar Cruise Control (MRCC)
Smart Brake Support (SBS)
The radar sensor (front) is mounted behind the radiator grille.
Refer to Radar Sensor (Front) on page 4-176 .

i-ACTIVSENSE
Laser sensor (front)
The laser sensor (front) emits a near-infrared laser beam and receives the beam re À ected
off the re À ective surface of a vehicle in front, and the detected beam is then used for
measurement. The following systems also use the laser sensor (front).
Smart City Brake Support [Forward] (SCBS F)
Smart Brake Support (SBS)
The laser sensor (front) is installed at the top of the windscreen near the rearview mirror.
Refer to Laser Sensor (Front) on page 4-179 .
Radar sensors (rear)
The radar sensors (rear) function by detecting the radio waves re À ected off a vehicle
approaching from the rear or an obstruction sent from the radar sensors. The following
systems also use the radar sensors (rear).
Blind Spot Monitoring (BSM)
Rear Cross Traf ¿ c Alert (RCTA)
The radar sensors (rear) are installed inside the rear bumper, one each on the left and right
sides.
Refer to Radar Sensors (Rear) on page 4-181 .
Ultrasonic sensors (rear)
The ultrasonic sensors (rear) function by detecting the ultrasonic waves re À ected off
obstructions at the rear sent from the ultrasonic sensors. The following systems also use the
ultrasonic sensors (rear).
Smart City Brake Support [Reverse] (SCBS R)
The ultrasonic sensors (rear) are mounted in the rear bumper.
Refer to Ultrasonic Sensors (Rear) on page 4-183 .

WARNING
Always check the surrounding area visually before making an actual lane change:
The system is only designed to assist you in checking for vehicles at your rear when
making a lane change. Due to certain limitations with the operation of this system,
the Blind Spot Monitoring (BSM) warning indicator light, the warning sound and the
warning screen indicator display may not activate or they might be delayed even though
a vehicle is in an adjacent driving lane. Always make it your responsibility as a driver to
check the rear.
NOTE
The Blind Spot Monitoring (BSM) will operate when all of the following conditions
are met:
The ignition is switched ON.
The Blind Spot Monitoring (BSM) OFF switch is pressed and the BSM OFF switch
indicator light is turned off.
The vehicle speed is about 30 km/h (19 mph) or faster.
The Blind Spot Monitoring (BSM) will not operate under the following circumstances.
The vehicle speed falls below about 25 km/h (15 mph) even though the Blind Spot
Monitoring (BSM) OFF switch indicator light is turned off.
The shift lever (manual transaxle)/selector lever (automatic transaxle) is shifted to
reverse (R) and the vehicle is reversing.
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
Repairer as soon as possible.
Some problem with the system including the Blind Spot Monitoring (BSM) warning
indicator lights is detected.
A large deviation in the installation position of a radar sensor (rear) on the vehicle
has occurred.
There is a large accumulation of snow or ice on the rear bumper near a radar sensor
(rear). Remove any snow, ice or mud on the rear bumper.
Driving on snow-covered roads for long periods.
The temperature near the radar sensors (rear) becomes extremely hot due to driving
for long periods on slopes during the summer.
The battery voltage has decreased.

When Driving
i-ACTIVSENSE
NOTE
Under the following conditions, the radar sensors (rear) cannot detect target objects or
it may be dif ¿ cult to detect them.
A vehicle is in the detection area at the rear in an adjacent driving lane but it does
not approach. The Blind Spot Monitoring (BSM) determines the condition based on
radar detection data.
A vehicle is travelling alongside your vehicle at nearly the same speed for an
extended period of time.
Vehicles approaching in the opposite direction.
A vehicle in an adjacent driving lane is attempting to pass your vehicle.
A vehicle is in an adjacent lane on a road with extremely wide driving lanes. The
detection area of the radar sensors (rear) is set at the road width of expressways.
In the following case, the À ashing of the Blind Spot Monitoring (BSM) warning
indicator light, and the activation of the warning sound and the warning screen
indicator display may not occur or they may be delayed.
A vehicle makes a lane change from a driving lane two lanes over to an adjacent
lane.
Driving on steep slopes.
Crossing the summit of a hill or mountain pass.
The turning radius is small (making a sharp turn, turning at intersections).
When there is a difference in the height between your driving lane and the adjacent
lane.
Directly after the Blind Spot Monitoring (BSM) system becomes operable by
changing the setting.
If the road width is extremely narrow, vehicles two lanes over may be detected.
The detection area of the radar sensors (rear) is set according to the road width of
expressways.

*Some models.
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 about
30 km/h (19 mph) or faster, and if your vehicle approaches a vehicle ahead more closely
than what is appropriate for maintaining distance between the vehicles according to the
vehicle speed, a noti ¿ cation in the active driving display is indicated to advise you to keep a
safe 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
noti ¿ 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 traf ¿ 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) system may not operate normally
under the following conditions:
The Dynamic Stability Control (DSC) has a malfunction.
The vehicle ahead is travelling at an extremely slow speed.
The system does not operate with the following objects:
Vehicles approaching in the opposite direction.
Stationary objects (stopped vehicles, obstructions)
