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.

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 4-130.
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 7-30.
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 sufficient 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 s
witch the headlights
automatically between high and low
beams after the igni tion is switched ON
and the headlight sw itch is in the AUTO
and high beam position.
The HBC determines that it is dark based
on the brightness of the surrounding area.
At the same time, the HBC indicator light
(green) in the instrument cluster
illuminates.

The HBC determines that it is dark based
on the brightness of the surrounding area.
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 Personalization
Features on page 9-9.

Lane Departure Warning System (LDWS)*
The LDWS notifies the driver that the vehicle may be deviating from its lane.
The system detects the white or yellow lines on the traffic lane using the Forward Sensing
Camera (FSC) and if it determines that the vehicle may be devia ting from its lane, it notifies
the driver using the active driv ing display (vehicles with active driving display), and by
flashing the LDWS warning light a nd activating the LDWS warning beep.
Use the LDWS when you drive the vehicle on roads with white or yellow lines.
Refer to Forward Sensing Camera on page 4-130.

The warning light illuminates whe n the system has a malfunction.
Refer to Warning Lights on page 4-24.
WA R N I N G
Do not use the LDWS under the following conditions:
The system may not operate adequately accordin g to the actual driving conditions, resulting
in an accident.
 Driving on roads with tight curves.
 Driving under bad weather conditions (rain, fog, and snow).

CX-3_8GR7-EA-18B_Edition1 2017-12-20 16:18:14

The functions of the LDWS have limitations:
Always stay on course using the steering wheel and drive with care. The system is not
designed to compensate for a driver’s lack of caution and if you rely too much on the LDWS it
could lead to an accident. The driver is resp onsible for assuring lane changes and other
maneuvers. Always pay attention to the directi on in which the vehicle is traveling and the
vehicle’s surroundings.
CAUTION
Do not modify the suspension. If the vehicle he ight or the damping force of the suspensions is
changed, the LDWS may not operate correctly.
NOTE
•If your vehicle deviates from its traffic lane, the LDWS operates (warning sound and
indicator light). Steer the vehicle adequately to drive the vehicle to the center of the lane.
•When the turn signal lever is operated for a lane change, the LDWS warning is
automatically canceled. The LDWS warning becomes operable when the turn signal lever
is returned and the system detects the white or yellow lines.
•If the steering wheel, accelerator pedal, or brake pedal is operated abruptly and the
vehicle moves close to a white or yellow line, the system determines that the driver is
making a lane change and the LDWS warning is automatically canceled.
•The LDWS may not operate during the period immediately after the vehicle has deviated
from its lane and the LDWS has operated, or the vehicle deviates from its lane repeatedly
within a short period of time.
•The LDWS does not operate if it does not det ect the white or yellow lines of the traffic
lane.
•Under the following conditions, the LDWS may not be able to detect white or yellow lines
correctly and the LDWS may not operate correctly.
•If an object placed on the dashboard is reflected in the windshield and picked up by the
camera.
•Heavy luggage is loaded in the luggage compartment or on the rear seat and the
vehicle is inclined.
•The tire pressures are not adjusted to the specified pressure.
•When the vehicle is driven on the entry and exit to or from the rest area or tollgate of a
highway.
•The white or yellow lines are less visi ble because of dirt or paint flaking.
•The vehicle ahead is running near a white or yellow line and the line is less visible.
•A white or yellow line is less visible be cause of bad weather (rain, fog, or snow).
•The vehicle is driven on a temporary lane or section with a closed lane due to
construction.
