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

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).
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 Sensor (Rear) (Search).
The High Beam Control System (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 Warning/Indicator Lights (Search).
While driving the vehicle at a speed of about 30 km/h (18 mph), 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 illuminates or flashes when the system has a malfunction.
Refer to Warning/Indicator Lights (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 High Beam Control System (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 curves 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.
The adjustable speed limiter is a function to prevent the vehicle from being driven at a vehicle speed faster than a set speed. The vehicle speed is controlled to kept it below the set speed even if the accelerator pedal is depressed.
The adjustable speed limiter can be set between 30 km/h (20 mph) and 200 km/h (125 mph).
The vehicle speed may exceed the set speed when the vehicle is driven on a down slope, however, the system notifies the driver by flashing the display and operating a warning sound.
Always turn off the system when changing drivers:
If the driver is changed and the new driver is unaware of the adjustable speed limiter function, the vehicle may not accelerate when the driver depresses the accelerator pedal, leading to an accident.
The system consists of the adjustable speed limiter display in the instrument cluster and the speed limiter switch on the steering wheel.
The setting status of the adjustable speed limiter is displayed in the multi-information display in the instrument cluster.
Stand-by display
Displays when the speed limiter switch is operated and the system is turned on.
Turns off when the system is turned off.
Setting display
Displays when the SET/SET
switch is operated and the speed is set.
Cancel display
Displays when any of the following operations is done and the system is temporarily cancelled.
Cancel switch is operated
Accelerator pedal is strongly depressed
If the vehicle speed exceeds the set speed by about 3 km/h (2 mph) or more, a warning sound operates continuously and the adjustable speed limiter display flashes at the same time. The warning sound operates and the display flashes until the vehicle speed decreases to the set speed or less.
Verify the safety of the surrounding area and adjust the vehicle speed by applying the brakes. Additionally, keep a safer distance from the vehicles behind you.
If the set speed is set lower than the current vehicle speed by pressing the SET or RESUME switch, the warning beep is not activated for about 30 seconds even if
the vehicle speed is faster than the newly set speed by 3 km/h (2 mph). Be careful
not to drive over the set speed
When the system is temporarily cancelled by depressing the accelerator pedal fully and the adjustable speed limiter display indicates the cancellation at the same time, a cancel warning beep is heard once. If the vehicle speed exceeds the set speed by about 3 km/h (2 mph) or more while the cancel display is displayed, the set speed display flashes but the warning sound is not operated.
Press the speed limiter switch to turn the system on. The adjustable speed limiter display is displayed in the multi-information display.
To turn the system off, press the speed limiter switch while the adjustable speed limiter is displayed. The adjustable speed limiter display in the multi-information display turns off.
Always verify the safety of the surrounding area when setting the adjustable speed limiter:
If the speed is set lower than the current vehicle speed, the vehicle speed is decreased to the set speed. Verify the safety of the surrounding area and keep a safe distance between vehicles ahead and behind you.
Press the speed limiter switch to turn the system on.
Press the SET or SET
to set the speed. When the current vehicle speed is 30 km/h (20 mph) or more, the
speed is set to the current vehicle speed. When the current vehicle speed is less
than 30 km/h (20 mph), the speed is set to 30 km/h (20 mph).
To increase the set speed, press the SET switch continuously. The set speed can be adjusted in 10 km/h (5 mph) increments.
The set speed can also be adjusted in about 1 km/h (1 mph) increments by pressing
the SET
switch momentary. For example, the set speed increases about 4 km/h (4 mph) by pressing
the SET
switch 4 times.
To decrease the set speed, press the SET switch continuously. The set speed can be adjusted in 10 km/h (5 mph) decrements.
The set speed can also be adjusted in about 1 km/h (1 mph) increments by pressing
the SET
switch momentary. For example, the set speed decreases about 4 km/h (4 mph) by pressing
the SET
switch 4 times.
The system does not operate when the cruise control/Mazda Radar Cruise Control (MRCC) is on.
The system is temporarily cancelled when the vehicle is accelerated by depressing the accelerator pedal strongly, however, it resumes when the vehicle speed decreases to the set speed or less.
The vehicle speed may exceed the set speed on a down slope.
The system is temporarily cancelled (stand-by status) when any of the following operations is done while the adjustable speed limiter is displayed.
CANCEL switch is pressed
Accelerator pedal is strongly depressed
Press the RESUME switch to resume the operation at the previous set speed. The adjustable speed limiter display remains displayed.
The set speed can be set by pressing the SET or SET
switch while the system is in stand-by status.
The adjustable speed limiter is not cancelled by depressing the brake pedal.
