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).

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) (Search).

Ultrasonic sensors (rear)

The ultrasonic sensors (rear) function by detecting the ultrasonic waves reflected 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) (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 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 (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.

The system switches the headlights to the high beams after the ignition is switched ON and the headlight switch is in the position. The Adaptive LED Headlights (ALH) indicator light (green) in the instrument cluster turns on simultaneously.

The Adaptive LED Headlights (ALH) determine that it is nighttime based on the brightness of the surrounding area.

The system cancels operation when the headlight switch is turned to a position other than , the headlights are manually switched to low beams, or the high beams are flashed on and off.

 

---

The system can be changed so that the Adaptive LED Headlights (ALH) do not operate.

Refer to Personalisation Features (Search).

1. The system goes on operation standby when the LDWS OFF 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.

   

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.

   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 turn.

   • 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.

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 30 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.

Close Note

Press the LDWS OFF switch to cancel the LDWS. The LDWS OFF indicator light turns on.

If the system determines that there is the possibility of a lane departure, the LDWS warning beep activates and the LDWS warning light flashes. Operate the steering wheel appropriately and steer the vehicle to the centre of the lane.

For vehicles equipped with the active driving display, if there is the possibility of a lane departure, the system indicates the direction it determines that the vehicle is deviating in the active driving display.

Indication on display

 

---

• If the LDWS warning sound is set to rumble^*1, the sound will be heard from the vehicle speaker on the side which the system determined the vehicle may be deviating from its lane.

• It may be difficult to hear the LDWS warning beep depending on the surrounding conditions such as outside noise.

• The volume of the LDWS warning sound can be changed.

  Refer to Personalisation Features (Search).

• The type of warning sound (rumble^*1/beep) on the LDWS can be changed.

  Refer to Personalisation Features (Search).

1. A rumble strip is a series of grooves in the road pavement surface positioned at specific intervals, and when the vehicle passes over it a vibration and rumble sound is produced which alerts the driver that the vehicle is departing from the lane.

   The rumble sound is a reproduction of the sound which occurs when a vehicle passes over a rumble strip.
