i-ACTIVSENSE

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.

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 Contact Authorized Mazda Dealer and Have Vehicle Inspected on page 7-36.

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 traffic). 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 traffic).



The Adaptive Front Lighting System (AFS) function can be switched to operable/

inoperable using the personalization function.

Refer to Personalization Features on page 9-9.

*Some models.

4-77

When Driving

i-ACTIVSENSE

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 4-105.

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).

The recognition distance of the

Forward Sensing Camera (FSC)

varies according to the

surrounding conditions.

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 deviating from its lane, it notifies

the driver by flashing the LDWS warning light and activating the LDWS warning beep, and

by the multi-information display (vehicles with multi-information display).

Use the LDWS when you drive the vehicle on roads with white or yellow lines.

Refer to Forward Sensing Camera on page 4-105.

WARNING

Do not use the LDWS under the following conditions:

The system may not operate adequately according to the actual driving conditions, resulting

in an accident.

Driving on roads with tight curves.

Driving under bad weather conditions (rain, fog, and snow).

*Some models.

4-81

When Driving

i-ACTIVSENSE

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 responsible for assuring lane changes and other

maneuvers. Always pay attention to the direction in which the vehicle is traveling and the

vehicle’s surroundings.

CAUTION

Do not modify the suspension. If the vehicle height 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 detect the white or yellow lines of the traffic



lane.

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 by alerting the driver to 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 turns on the BSM warning lights

equipped on the door mirrors depending on the conditions. If the turn signal lever is

operated to signal a lane change in the direction in which the BSM warning light is

illuminated, the system warns the driver of a vehicle in the detection area by flashing the

BSM warning light and activating a beep sound.

The detection area on this system covers the driving lanes on both sides of the vehicle and

from the rear part of the doors to about 50 m (164 ft) behind the vehicle.

Smart City Brake Support (SCBS)^*

The SCBS system alerts the driver of a possible collision using an indication in the display

and a warning sound when the Forward Sensing Camera (FSC) detects a vehicle ahead and

determines that a collision with a vehicle ahead is unavoidable while the vehicle is being

driven at a vehicle speed of about 4 to 80 km/h (2 to 50 mph). In addition, the system

reduces damage in the event of a collision by operating the brake control (Smart City Brake

Support (SCBS) brake) when the system determines that a collision is unavoidable while the

vehicle is being driven at a vehicle speed of about 4 to 30 km/h (2 to 18 mph). It may also

be possible to avoid a collision if the relative speed between your vehicle and the vehicle in

front of you is less than about 20 km/h (12 mph). In addition, when the driver depresses the

brake pedal while the system is in the operation range at about 4 to 30 km/h (2 to 18 mph),

the brakes are applied firmly and quickly to assist. (Brake Assist (Smart City Brake Support

(SCBS) brake assist))
