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 with Stop & Go function (MRCC with Stop & Go function)
-
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).
Front camera/side cameras/rear view camera
The front camera, side cameras, and rear camera shoot images of the area surrounding the vehicle. The 360° View Monitor uses each camera.
Cameras are installed to the front bumper, door mirrors, and liftgate.
Refer to Front Camera/Side Cameras/Rear Camera (Search).
Adaptive Front Lighting System (AFS) (Some Models)
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.
-
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 personalisation function.
Refer to Personalisation Features (Search).
High Beam Control System (HBC) (Some Models)
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) (Search).
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 warning light turns on when the system has a malfunction.
Refer to Contact Authorised Mazda Repairer and Have Vehicle Inspected (Search).
-
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 HBC and drive the vehicle while paying sufficient attention to safety. Switch the headlights between the high beams and low beams manually if necessary.
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 insufficient 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.
To Operate the System
The 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 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.
-
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 Personalisation Features (Search).
Mazda Radar Cruise Control with Stop & Go function (MRCC with Stop & Go function) (Automatic Transaxle) (Some Models)
The MRCC with Stop & Go function system is designed to maintain headway control*1 with a vehicle ahead according to your vehicle's speed using a radar sensor (front) to detect the distance to the vehicle ahead and a preset vehicle speed without you having to use the accelerator or brake pedals.
-
Headway Control: Control of the distance between your vehicle and the vehicle ahead detected by the Mazda Radar Cruise Control (MRCC) system.
Additionally, if your vehicle starts closing in on the vehicle ahead such as if the vehicle ahead brakes suddenly, a warning sound and a warning indication in the display are activated simultaneously to alert you to maintain a sufficient distance between the vehicles.
If the vehicle ahead stops while you are following behind it, your vehicle will stop and be held stopped automatically (stop hold control), and headway control will resume when you resume driving the vehicle such as by pressing the RES switch.
Also refer to the following before using the MRCC with Stop & Go function.

Radar sensor (front) (Search)
Do not rely completely on the MRCC with Stop & Go function:
The MRCC with Stop & Go function system has detection limitations depending on the type of vehicle ahead and its conditions, the weather conditions, and the road conditions. Additionally, the system may be unable to decelerate sufficiently to avoid hitting the vehicle ahead if the vehicle ahead applies the brakes suddenly or another vehicle cuts into the driving lane, which could result in an accident.
Always drive carefully and verify the surrounding conditions and depress the brake pedal or accelerator pedal while keeping a safer distance from vehicles ahead or on-coming vehicles.
Do not use the MRCC with Stop & Go function system in the following locations, using the MRCC with Stop & Go function system at the following locations may result in an unexpected accident:
-
General roads other than highways (Driving under these conditions using the MRCC with Stop & Go function system is not possible.)
-
Roads with sharp curves and where vehicle traffic is heavy and there is insufficient space between vehicles.
-
Roads where frequent and repetitive acceleration and deceleration occur (Driving under these conditions using the MRCC with Stop & Go function system is not possible).
-
When entering and exiting interchanges, service areas, and parking areas of highways (If you exit a highway while headway control is in use, the vehicle ahead will no longer be tracked and your vehicle may accelerate to the set speed).
-
Slippery roads such as ice or snow-bound roads (Tyres could spin causing you to lose vehicle control, or the stop hold control may not operate.)
-
Long, descending slopes (to maintain distance between vehicles, the system automatically and continuously applies the brakes which could result in the loss of brake power.)
-
Slopes with a steep gradient (The vehicle ahead may not be detected correctly, your vehicle may slide while stopped by the stop hold control, and it may accelerate suddenly after it starts moving.)
For safety purposes, switch the MRCC with Stop & Go function system off when it is not being used.
Do not get out of the vehicle while the stop hold control is operating:
Getting out of the vehicle while the stop hold control is operating is dangerous as the vehicle may move unexpectedly and result in an accident. Before getting out of the vehicle, switch the MRCC with Stop & Go function system off, shift the selector lever to the P position, and apply the parking brake.
If your vehicle is towed or you are towing something, switch the MRCC with Stop & Go function system off to prevent a mis-operation.
-
The MRCC with Stop & Go function system does not detect the following as physical objects.
-
Vehicles approaching in the opposite direction
-
Pedestrians
-
Stationary objects (stopped vehicles, obstructions)
-
If a vehicle ahead is travelling at an extremely low speed, the system may not detect it correctly.
-
-
During headway control travel, do not set the system for detection of two-wheeled vehicles such as motorcycles and bicycles.
-
Do not use the MRCC with Stop & Go function system under conditions in which close proximity warnings are frequently activated.
-
During headway control travel, the system accelerates and decelerates your vehicle in conjunction with the speed of the vehicle ahead. However, if it is necessary to accelerate for a lane change or if the vehicle ahead brakes suddenly causing you to close in on the vehicle rapidly, accelerate using the accelerator pedal or decelerate using the brake pedal depending on the conditions.
-
While the MRCC with Stop & Go function system is in use, it does not cancel even if the selector lever is operated and any intended engine braking does not occur. If deceleration is required, lower the set speed or depress the brake pedal.
-
The sound of the automatic brakes operating may be heard, however, it does not indicate a problem.
-
The brake lights turn on while the MRCC with Stop & Go function automatic braking is operating, however, they may not turn on while the vehicle is on a downslope at the set vehicle speed or travelling at a constant speed and following a vehicle ahead.

How to change the set vehicle speed
To accelerate/decelerate using the SET switch
When you press the SET switch, the vehicle accelerates and when you press the SET switch, it decelerates.
|
European models |
Except European models |
|
|---|---|---|
|
Short press |
1 km/h (1 mph) |
5 km/h (5 mph) |
|
Long press |
10 km/h (5 mph) |
|
For example, the set vehicle speed is changed by pressing the SET switch 4 times as follows:
(European models)
The vehicle speed accelerates or decelerates by 4 km/h (4 mph).
(Except European models)
The vehicle speed accelerates or decelerates by 20 km/h (20 mph).
To increase speed using accelerator pedal
Depress the accelerator pedal and press and release the SET switch or SET switch at the desired speed. If the switch is not operated, the system returns to the set speed after you release your foot from the accelerator pedal.
The warnings and brake control do not operate while the accelerator pedal is depressed.
-
The setting speed can be changed by operating the SET
switch or SET switch during stop hold control. -
When accelerating using the SET
switch while in headway control, the set vehicle speed can be adjusted but acceleration is not possible. If there is no longer a vehicle ahead, acceleration continues until reaching the set vehicle speed. For the set vehicle speed, check the set vehicle speed indication in the display. -
When depressing the accelerator pedal, the inter-vehicle distance indication in the display changes to the white-line indication.
-
(European models)
When switching to a passing lane and operating the direction indicator, the system provides more acceleration automatically if it determines that more acceleration is required. Drive while being careful of the road ahead because you could approach the vehicle ahead too closely.
