i-ACTIVSENSE

i-ACTIVSENSE

i-ACTIVSENSE is a collective term covering a series of advanced safety and driver support systems which make use of cameras and sensors. The 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.

Front Radar Sensor

Your vehicle is equipped with a front radar sensor.

  1. Front radar sensor

 

The following systems also use the front radar sensor.

  • Distance & Speed Alert (DSA)

  • Mazda Radar Cruise Control with Stop & Go function (MRCC with Stop & Go function)

  • Traffic Jam Assist (TJA)

  • Smart Brake Support (SBS) forward drive detection

The front radar sensor functions by detecting the radio waves reflected off a vehicle ahead or an obstruction sent from the radar sensor.

 


Heed the following precautions to assure correct operation of each system.

  • Do not apply a sticker (including a transparent one) to the front radar sensor cover or replace the front radar sensor cover with a product other than a genuine product.

  • The front radar sensor includes a function for detecting soiling of the radar sensor's front surface and informing the driver, however, depending on the conditions, it may require time to detect or it may not detect plastic shopping bags, ice or snow. If this occurs, the system may not operate correctly, therefore always keep the front radar sensor clean.

  • If “Safety and Driver Support Systems Temporarily Disabled. Front Radar Obscured. Drive Safely” is displayed on the multi-information display of the instrument cluster, clean the area around the front radar sensor.

  • Do not install a grille guard.

  • If the front part of the vehicle has been damaged in a vehicle accident, the position of the front radar sensor may have moved. Stop the system immediately and always have the vehicle inspected at an Authorized Mazda Dealer.

  • Do not use the front bumper to push other vehicles or obstructions such as when pulling out of a parking space. Otherwise, the front radar sensor could be hit and its position deviated.

  • For repairs, replacement or paint work around the front radar sensor, consult an Authorized Mazda Dealer.

  • Always use tires for all wheels that are of the specified size, and the same manufacturer, brand, and tread pattern. In addition, do not use tires with significantly different wear patterns on the same vehicle as the system may not operate normally.

 


  • If the lead-acid battery power is weak, the system may not operate correctly.

  • When driving on roads with little traffic and few vehicles ahead or obstructions for the front radar sensor to detect, “Safety and Driver Support Systems Temporarily Disabled. Front Radar Obscured. Drive Safely” may be temporarily displayed, however, this does not indicate a problem.

  • The radar sensors are regulated by the relevant radio wave laws of the country in which the vehicle is driven. If the vehicle is driven abroad, authorization from the country in which the vehicle is driven may be required.

When the vehicle is driven on roads in which there is an elevated road on one side, the front radar sensor function may be restricted temporarily.

When any of the following conditions is met, the front radar sensor may not be able to detect vehicles ahead or obstructions correctly and each system may not operate normally.

  • The rear surface of a vehicle ahead does not reflect radio waves effectively (such as an unloaded trailer, a vehicle with a loading platform covered by a soft top, a vehicle with a hard plastic liftgate, and a round-shaped vehicle).

  • A vehicle ahead has limited areas that can reflect radio waves (such as a low profile vehicle).

  • Under bad weather conditions (rain, fog, and snow).

  • Front visibility is reduced (due to a vehicle ahead casting off water, snow, or sand).

  • Foreign matter (ice, snow, or dirt) is on the surface of the front radar sensor cover.

  • Your vehicle is tilted (such as when heavy luggage is in the luggage compartment or on the rear seat).

  • The vehicle is driven near facilities or objects emitting strong radio waves.

When any of the following conditions is met, the front radar sensor may detect vehicles in the opposite lane or surrounding obstructions, or it may not be able to detect vehicles ahead or obstructions, and each system may not operate normally.

  • The vehicle ahead enters the front radar sensor’s blind spot.

  • The distance to the vehicle ahead is extremely close.

  • The vehicle ahead is being driven in an unstable condition.

  • A vehicle suddenly comes close such as by cutting into your lane.

  • The vehicle is entering or exiting a curve.

  • The vehicle is driven on a continuously curving road.

  • The vehicle is driven on roads with repeated up and downslopes.

  • The vehicle is driven on roads with narrow lanes.

  • The vehicle is driven on poor roads or unpaved roads.

Rear Side Radar Sensor

Your vehicle is equipped with rear side radar sensor.

  1. Rear side radar sensor

 

The following systems also use the rear side radar sensor.

  • Blind Spot Monitoring (BSM)

  • Rear Cross Traffic Alert (RCTA)

  • Smart Brake Support (SBS) reverse drive detection

  • Emergency Lane Keeping (ELK)

The rear side radar sensors emit radio waves and detect the radio waves reflected off a vehicle approaching from the rear or an obstruction.

 


Heed the following precautions to assure correct operation of each system.

  • Always keep the surface of the rear bumper near the rear side radar sensors clean so that they operate normally. Also, do not apply items such as stickers.

    Refer to Exterior Care (Search).

  • If the rear bumper receives a severe impact, the system may no longer operate normally. Stop the system immediately and have the vehicle inspected at an Authorized Mazda Dealer.

  • Vehicles are shipped with the direction of the rear side radar sensor adjusted for each vehicle to a loaded vehicle condition so that the rear side radar sensor detect approaching vehicles correctly. If the direction of the rear side radar sensor has deviated for some reason, have the vehicle inspected at an Authorized Mazda Dealer.

  • For repairs or replacement of the rear side radar sensor, or bumper repairs, paintwork, and replacement near the radar sensors, consult an Authorized Mazda Dealer.

 


The radar sensors are regulated by the relevant radio wave laws of the country in which the vehicle is driven. If the vehicle is driven abroad, authorization from the country in which the vehicle is driven may be required.

When any of the following conditions is met, the detection ability of the rear side radar sensors may decrease and each system may not operate normally.

  • Under bad weather conditions (rain, fog, and snow).

  • The rear bumper around a rear side radar sensor is deformed.

  • Foreign matter (such as ice, snow, and mud) is adhering to the rear bumper around a rear side radar sensor.

The rear side radar sensors may not detect the following target objects.

  • Small motorcycles

  • Bicycles

  • Pedestrians

  • Animals

  • Shopping carts

  • Stationary objects on the road or roadside

  • Vehicles with shapes that may not reflect radar waves (such as unloaded trailers with low vehicle heights and sports cars).

Distance & Speed Alert (DSA) (Some Models)

Driver Monitoring (DM)

The DM is a system which detects driver fatigue and sleepiness, and encourages the driver to take a rest.

While driving the vehicle at about 5 km/h (3 mph) or faster, the DM detects changes in the driver's facial features using the driver monitoring camera. The system then estimates the amount of accumulated fatigue and sleepiness of the driver and encourages the driver to take a rest using a warning indication in the instrument cluster and a warning sound.

Two types of warning indication patterns are set for notifying the driver based on the estimated amount of accumulated fatigue and sleepiness of the driver.

  • Fatigue and sleepiness are detected: Warning pattern (caution)

  • Much more fatigue and sleepiness are detected: Warning pattern (warning)

 


Do not rely completely on the DM and always drive carefully:

The DM is a system which detects driver fatigue and sleepiness, and encourages the driver to take a rest. This is not designed to prevent driver fatigue and sleepiness, and over-reliance on the system could lead to an accident. Drive carefully and turn the steering wheel appropriately.

In addition, the system may not be able to detect driver fatigue and sleepiness correctly depending on the traffic and driving conditions. The driver must take sufficient rest in order to drive safely.

Operation conditions

The DM begins monitoring after 20 minutes have passed since the driver began driving the vehicle and when the vehicle speed is about 5 km/h (3 mph) or faster.

 


  • If the vehicle speed decreases to less than about 5 km/h (3 mph) while the DM is monitoring, the DM stops monitoring for 6 minutes even if the vehicle speed returns to about 5 km/h (3 mph) or faster.

Stop Hold Control

While in headway control using the Traffic Jam Assist (TJA), your vehicle will stop when a vehicle ahead stops. When the vehicle is stopped and the stop hold control operates, the TJA indicator light turns on.

 


The parking brake is automatically applied and the vehicle is held in its stopped position when 10 minutes or longer have passed since the stop hold control operated. When this occurs, the TJA is temporarily canceled.

Resuming driving

While in stop hold control, if the vehicle ahead starts moving and the distance from the vehicle increases, the stop hold control will be canceled and your vehicle will resume driving by performing any of the following operations.

  • Press the RES switch.

  • Depress the accelerator pedal.

 


If the vehicle ahead starts moving within three seconds after your vehicle is stopped, the headway control will continue even if you do not resume driving your vehicle.

Resume driving information

If you do not resume driving within a few seconds after the vehicle ahead starts moving during stop hold control, the vehicle-ahead indication on the multi-information display flashes to urge you to resume driving. If you still do not resume driving after the indicator light flashes, a sound is activated to urge you to resume driving.

Smart Brake Support (SBS)

The SBS is a system designed to detect target objects using sensors and cameras equipped on the vehicle, and to reduce damage in the event of a collision by operating the brake control if there is the possibility of your vehicle colliding with a target object.

One part of the SBS functions when you are driving forward and the other part functions when you are driving in reverse.

Refer to Forward drive detection (Search).

Refer to Reverse drive detection (Search).

Margin of Error Between Road Surface on Screen and Actual Road Surface

There might be some margin of error between the road surface appearing on the screen and the actual road surface. A margin of error in the perceived distance could lead to an accident, therefore be aware of the following conditions which can more easily produce errors in the perceived distance.

 

The vehicle tilts due to weight of passengers and cargo.

If the vehicle is tilted, obstructions picked up by a camera can appear farther or closer than the actual distance from the vehicle.

Front camera

  1. Obstruction

  2. Margin of error

Side camera
