i-ACTIVSENSE

Active Safety Technology supports safer driving by helping the driver to recognise potential hazards and avert accidents.

Driver awareness support systems

Nighttime visibility

• Adaptive Front Lighting System (AFS)
• High Beam Control System (HBC)

Left/right side and rear side detection

• Lane Departure Warning System (LDWS)
• Blind Spot Monitoring (BSM) System

Inter-vehicle distance recognition

• Distance Recognition Support System (DRSS)

Rear obstruction detection when leaving a parking space

• Rear Cross Traffic Alert (RCTA)

Driver support systems

Inter-vehicle distance

• Mazda Radar Cruise Control (MRCC)

Speed control

• Adjustable Speed Limiter

Pre-crash safety technology is designed to assist the driver in averting collisions or reduce their severity in situations where they cannot be avoided.

Collision damage reduction in low vehicle speed range

Forward driving

• Smart City Brake Support (SCBS)

Collision damage reduction in medium/high speed range

• Smart Brake Support (SBS)

Forward sensing camera (FSC)

The Forward Sensing Camera (FSC) determines the conditions ahead of the vehicle while travelling 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)

• Smart Brake Support (SBS)

The Forward Sensing Camera (FSC) is installed at the top of the windscreen near the rearview mirror.

Refer to Forward Sensing Camera (FSC) (Search).

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)

• Distance Recognition Support System (DRSS)

• Smart Brake Support (SBS)

The radar sensor (front) is mounted behind the radiator grille.

Refer to Radar Sensor (Front) (Search).

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)

• Smart Brake Support (SBS)

The laser sensor (front) is installed at the top of the windscreen near the rearview mirror.

Refer to Laser Sensor (Front) (Search).

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 sides.

Refer to Radar Sensors (Rear) (Search).

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.

 

---

• When the vehicle speed is 30 km/h (18 mph) or higher, 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 (Search).

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.

1. The system goes on operation standby when the LDWS switch is pressed and the LDWS OFF indicator light in the instrument cluster turns off. For vehicles equipped with the active driving display, the driving lane (border lines) is indicated in the display.

   

   Indication on display

   

2. Drive the vehicle in the centre of the driving lane while the LDWS OFF indicator light is turned off. The system becomes operational when all of the following conditions are met.

   • The vehicle is driven in the centre of the driving lane with the white or yellow lines on the left and right sides, or on either side.

   • The vehicle speed is 70 km/h (44 mph) or faster.

   • The vehicle is driven on a straight road or road with gentle curves.

   For vehicles equipped with the active driving display, the driving lane is indicated in the display.

   Indication on display

   

   The LDWS does not operate in the following cases:

   • The system cannot detect white or yellow lines.

   • The vehicle speed is less than 65 km/h (40 mph).

   • The vehicle is making a sharp curve.

   • The vehicle is making a curve at an inadequate speed.

 

---

• The LDWS does not operate until the system detects a white or yellow line on either the left or right.

• When the system detects a white or yellow line on one side only, the system will activate the warning only when the vehicle deviates on the side where the white or yellow line is being detected.

• The distance and warning sensitivity (likelihood of a warning) which the system uses to determine the possibility of a lane departure can be changed.

  Refer to Personalisation Features (Search).

Auto cancel

In the following cases, the LDWS cancels automatically and the LDWS warning light in the instrument cluster turns on.

• The temperature inside the camera is high or low.

• The windscreen around the camera is foggy.

• The windscreen around the camera is blocked by an obstruction, causing poor forward visibility.

For vehicles equipped with the active driving display, the lane (border lines) is indicated in the display. The LDWS is enabled automatically when the operation conditions are met, and the LDWS warning light turns off.

Auto cancel warning

When the following operations are performed, the LDWS determines that the driver intends to make a lane change and the LDWS warning is cancelled automatically. The LDWS is enabled automatically after the driver performs the operation.

• The steering wheel is operated abruptly.

• The brake pedal is depressed abruptly.

• The accelerator pedal is depressed abruptly.

• The direction indicator lever is operated (after the direction indicator lever is returned, the LDWS may not operate for about 3 seconds which is the period of time required to make a lane correction).

 

---

After about 60 seconds have elapsed with the direction indicator lever left operating, the LDWS warning may operate if the vehicle is close to a white or yellow line.
