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 sen\
sors. These
systems consist of active safety and pre-crash safety systems.
These systems are designed to assist the driver in safer driving by redu\
cing 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 th\
e systems.

Camera and Sensors
Forward sensing camera (FSC)
The Forward Sensing Camera (FSC) determines the conditions ahead of th\
e vehicle while
traveling at night and detects traffic lanes. The following systems also use the Forward
Sensing Camera (FSC).
 High Beam Control system (HBC) Lane Departure Warning System (LDWS)
The Forward Sensing Camera (FSC) is installed at the top of the windsh\
ield near the
rearview mirror.
Refer to Forward Sensing Camera (FSC) on page 4-111.
Radar sensor (front)
The radar sensor (front) functions by detecting the radio waves reflected off a vehicle ahead
sent from the radar sensor. The following systems also use the radar sensor (front).
 Mazda Radar Cruise Control (MRCC) Forward Obstruction Warning (FOW)
The radar sensor (front) is mounted behind the radiator grille.
Refer to Radar Sensor (Front) on page 4-113.
Laser sensor (front)
The laser sensor (front) emits a near-infrared laser beam and receives the beam reflected
off the reflective 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 (SCBS)
The laser sensor (front) is installed at the top of the windshield nea\
r the rearview mirror.
Refer to Laser Sensor (Front) on page 4-116.
Radar sensors (rear)
The radar sensors (rear) function by detecting the radio waves reflected 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) System Rear Cross Traffic Alert (RCTA)
The radar sensors (rear) are installed inside the rear bumper, one each on the left and right

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) an\
d 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 ve\
hicle ahead
detected by the Mazda Radar Cruise Control (MRCC) system.
Additionally, if your vehicle starts closing in on the vehicle ahead because, for ex\
ample, the
vehicle ahead brakes suddenly, a warning sound and a warning indication in the display are
activated simultaneously to alert you to maintain a sufficient 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.
WARNING
Do not rely completely on the Mazda Radar Cruise Control (MRCC) system and always
drive carefully: The Mazda Radar Cruise Control (MRCC) system is designed to reduce load on the
driver, and although it maintains a constant vehicle speed, or specifically, it maintains
a constant distance between your vehicle and the detected vehicle ahead according to
the vehicle speed, the system has detection limitations depending on the type of vehicle
ahead and its conditions, the weather conditions, and the road conditions. Additionally,
the system may be unable to decelerate sufficiently to avoid hitting the vehicle ahead
if the vehicle ahead applies the brakes suddenly or another vehicle cuts into the driving
lane, which 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.
Do not use the Mazda Radar Cruise Control (MRCC) system in the following locations.
Otherwise, it could lead to an accident:
 Roads with sharp cur ves and where vehicle traffic is heavy and there is insufficient
space between vehicles. Roads where frequent and repetitive acceleration and
deceleration occur (Driving under these conditions using the Mazda Radar Cruise
Control (MRCC) system is not possible).
 When entering and exiting interchanges, service areas, and parking areas of highways
(If you exit a highway while headway control is in use, the vehicle ahead will no longer
be tracked and your vehicle may accelerate to the set speed).
 Slippery roads such as ice or snow-bound roads (The tires could spin causing you to
lose vehicle control). Long descending slopes (to maintain distance between vehicles, the system
automatically and continuously applies the brakes which could result in the loss of
brake power).

 During headway control travel, the system accelerates and decelerates your vehicle in
conjunction with the speed of the vehicle ahead. However, if it is necessary to accelerate
for a lane change or if the vehicle ahead brakes suddenly causing you to\
close in on the
vehicle rapidly, accelerate using the accelerator pedal or decelerate using the brake
pedal depending on the conditions.
 While the Mazda Radar Cruise Contr ol (MRCC) system is in use, it does not cancel even
if the selector lever (automatic transaxle)/shift lever (manual trans\
axle) is operated and
any intended engine braking will not occur. If deceleration is required, lower the vehicle
speed setting or depress the brake pedal.
 The brake lights are illuminated while the Mazda Radar Cruise Control (MRCC)
automatic braking is operating. The Mazda Radar Cruise Contr ol (MRCC) warning light (amber) turns on when the
system has a malfunction. Refer to Warning/Indicator Lights on page 4-20.
