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 drivin g 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 sol ely on the systems.

ecognizes headlights,
taillights and city lights during nighttime driving. In addition, it also detects the vehicle
ahead, pedestrians, or obstructions. The following systems also use the Forward Sensing
Camera (FSC).
High Beam Control System (HBC)
Lane-keep Assist System (LAS) & Lane Departure Warning System ( LDWS)
Traffic Sign Recognition System (TSR)
Advanced Smart City Brake Support (Advanced SCBS)
Smart City Brake Support [Forward] (SCBS F)

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 with Stop & Go function (MRCC with S top & Go function)
Distance Recognition Support System (DRSS)
Smart Brake Support (SBS)
The radar sensor (front) is mount ed behind the radiator grille.
Refer to Radar Sensor (Front) on page 4-220.
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)
Rear Cross Traffic 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 4-223.
Ultrasonic sensors (rear)
The ultrasonic sensors (rear) function by detecting the ultraso nic waves reflected off
obstructions at the rear sent fro m 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 4-225.
Front camera/side cameras/rear view camera
The front camera, side cameras, and rear camera shoot images of the area surrounding the
vehicle. The 360° View Monitor uses each camera.
Cameras are installed to the front bumper, door mirrors, and tr unk.
Refer to Front Camera/Side Cameras/Rear Camera on page 4-226.

Adaptive Front Lighting System (AFS)*
The adaptive front lighting system (AFS) automatically adjusts the headlight beams to the
left or right in conjunction with the operation of the steering wheel after the headlights have
been turned on and the vehicle speed is about 2 km/h (2 mph) or higher.
A system malfunction or operation conditions are indicated by a warning.
Refer to Contact Authorized Mazda Dealer and Have Vehicle Inspected on page 7-28.
NOTE
The Adaptive Front Lighting System (AFS) func tion can be switched to operable/inoperable
using the personalization function.
Refer to the Settings section in the Mazda Connect Owner's Manual.

High Beam Control System (HBC)*
The HBC determines the conditions in front of the vehicle using the Forward Sensing
Camera (FSC) while driving in darkness to automatically switch the headlights between
high and low beams.
Refer to Forward Sensing Camera (FSC) on page 4-215.
While driving the vehicle at a speed of about 30 km/h (19 mph) or more, the headlights are
switched to high beams when there are no vehicles ahead or appr oaching in the opposite
direction.
The system switches the headlights to low beams when one of the following occurs:
The system detects a vehicle or the headlights/lights of a vehicle approaching in the
opposite direction.
The vehicle is driven on roads lin ed with streetlamps or on roads in well-lit cities and
towns.
The vehicle is driven at less than about 20 km/h (12 mph).
Forward Sensing
Camera (FSC)
The recognition distance of the
Forward Sensing Camera (FSC)
varies according to the
surrounding conditions.
The warning light turns on when the system has a malfunction.
Refer to Contact Authorized Mazda Dealer and Have Vehicle Inspe
cted on page 7-28.
CAUTION
Do not adjust the vehicle he ight, modify the headlight units, or remove the camera,
otherwise the system will not operate normally.
Do not rely excessively on the HBC and drive the vehicle while paying sufficient attention to
safety. Switch the headlights between th e high beams and low beams manually if
necessary.

NOTE
The timing in which the system switches the headlights changes under the following
conditions. If the system does not switch the headlights appropriately, manually switch
between high and low beams according to the visibility as well as road and traffic
conditions.
When there are sources of light in the area such as street lamps, illuminated signboards,
and traffic signals.
When there are reflective objects in the surrounding area such as reflective plates and
signs.
When visibility is reduced under rain, snow and foggy conditions.
When driving on roads with sharp turn or hilly terrain.
When the headlights/rear lamps of vehicles in front of you or in the opposite lane are dim
or not illuminated.
When there is insufficient darkness such as at dawn or dusk.
When the luggage compartment is loaded with heavy objects or the rear passenger seats
are occupied.
When visibility is reduced due to a vehicle in front of you spraying water from its tires
onto your windshield.
▼ To Operate the System
The HBC operates to sw
itch the headlights
automatically between high and low
beams after the ignition is switched ON
and the headlight switch is in the AUTO
and high beam position.
The HBC determines t hat it is dark based
on the brightness of the surrounding area.
At the same time, th e HBC indicator light
(green) in the instrument cluster
illuminates.
NOTE
When the vehicle speed is about 30 km/h
(19 mph) or more, the headlights
automatically switch to high beams
when there are no vehicles ahead or
approaching in the opposite direction.
When the vehicle speed is less than
about 20 km/h (12 mph), the HBC
switches the headlights to low beams.
The low beams may not switch to high
beams when cornering.
Operation of the HBC function can be
disabled. Refer to the Settings section in
the Mazda Connect Owner's Manual.

Blind Spot Monitoring (BSM)
The BSM is designed to assist the driver in checking the area to the rear of the vehicle on
both sides during lane changes b y notifying the driver of the presence of vehicles
approaching from the rear in an adjacent lane.
The BSM detects vehicles approaching from the rear while traveling in the forward
direction at a speed of 10 km/h (6.3 mph) or faster and notifie s the driver by turning on the
BSM warning indicator light and displaying the vehicle detectio n screen (vehicles with
multi-information display and active driving display).
If the turn signal lever is operated to signal a turn in the di rection in which the BSM
warning indicator light is illuminated while the approaching ve hicle is detected, the BSM
notifies the driver of possible danger by turning on the BSM wa rning indicator light, and by
activating the warning sound and the warning screen indicator d isplay (vehicles with
multi-information display and active driving display).
The detection area on this system covers the driving lanes on b oth sides of the vehicle and
from the rear part of the front doors to about 50 m (164 ft) behind the vehicle.

Your vehicle
WA R N I N G
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 BSM warning
indicator light, the warning sound and the warn ing 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.
