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. 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)



 Adaptive LED Headlights (ALH)



 Driver Attention Alert (DAA)



 Lane Departure Warning System (LDWS)



 Traf¿ c Sign Recognition System (TSR)



 Advanced Smart City Brake Support (Advanced SCBS)



 Smart City Brake Support [Forward] (SCBS F)



 Smart Brake Support (SBS)

4–103
When Driving
i-ACTIVSENSE
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 4-179 .
Radar sensor (front)
The radar sensor (front) functions by detecting the radio waves reÀ ected off a vehicle ahead
sent from the radar sensor. The following systems also use the radar sensor (front).
 


 Mazda Radar Cruise Control (MRCC)



 Distance Recognition Support System (DRSS)



 Smart Brake Support (SBS)
The radar sensor (front) is mounted behind the radiator grille.
Refer to Radar Sensor (Front) on page 4-186 .
Radar sensors (rear)
The radar sensors (rear) function by detecting the radio waves reÀ 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 4-189 .
Ultrasonic sensors (rear)
The ultrasonic sensors (rear) function by detecting the ultrasonic waves reÀ 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 4-191 .

When Driving
i-ACTIVSENSE
*Some models.
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.
A system malfunction or operation conditions are indicated by a warning.
Refer to Warning/Indicator Lights on page 4-36 .
NOTE
  Headlights do not blind drivers approaching in the opposite direction no matter
what side of the road you must drive your vehicle (left-hand or right-hand traf¿ c).
Therefore, it is not necessary to adjust the optical axis of the headlights when
switching temporarily to driving on the opposite side of the road (left-hand or right-
hand traf¿ c).

 The Adaptive Front Lighting System (AFS) function can be switched to operable/
inoperable using the personalisation function.
 Refer to Personalisation Features on page 9-13 .

When Driving
i-ACTIVSENSE
*Some models.
High Beam Control System (HBC) *
The High Beam Control System (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 Warning/Indicator Lights on page 4-36 .
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 approaching 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 lined 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 Warning Lights on page 4-36 .
CAUTION
  Do not adjust the vehicle height, modify the headlight units, or remove the camera,
otherwise the system will not operate normally.
  Do not rely excessively on the High Beam Control System (HBC) and drive the
vehicle while paying suf¿ cient attention to safety. Switch the headlights between the
high beams and low beams manually if necessary.

When Driving
i-ACTIVSENSE
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 traf¿ c
conditions.
 
 When there are sources of light in the area such as street lamps, illuminated
signboards, and traf¿ c signals.

 When there are reÀ ective objects in the surrounding area such as reÀ ective 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 suf¿ cient 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 tyres
onto your windscreen.

When Driving
i-ACTIVSENSE
To Operate the System
The High Beam Control System (HBC)
operates to switch 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 High Beam Control System (HBC)
determines that it is dark based on the
brightness of the surrounding area. At the
same time, the High Beam Control System
(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
High Beam Control System (HBC)
switches the headlights to low
beams.
  The low beams may not switch to
high beams when cornering.
  Operation of the High Beam Control
System (HBC) function can be
disabled. Refer to Personalisation
Features on page 9-13 .
Manual Switching
Switching to low beams
Shift the lever to the low beam position.
The High Beam Control System (HBC)
indicator light (green) turns off.
Switching to high beams
Turn the headlight switch to the

position.
The High Beam Control System (HBC)
indicator light (green) turns off and the

is illuminated.

*Some models.
Adaptive LED Headlights (ALH) *
The Adaptive LED Headlights (ALH) are a system which uses the Forward Sensing Camera
(FSC) to determine the situation of a vehicle ahead or a vehicle approaching in the opposite
direction while driving at night to automatically switch the illumination range of the
headlights, the illuminated area, or the illumination brightness.
Refer to Forward Sensing Camera (FSC) on page 4-179 .
The Adaptive LED Headlights (ALH) are controlled between high and low beams as follows
to assure the driver’s visibility without dazzling a vehicle ahead or a vehicle approaching in
the opposite direction.
Glare-Free High Beam
This feature dims only the high-beam light shone on the vehicle ahead.
The high beams will dim while driving at a speed of about 40 km/h (25 mph) or faster.
When the vehicle speed is less than about 30 km/h (18 mph), the beams switch to the low
beams.


NOTE
The headlight high-beam indicator light turns on while the high beams are on.
