Front Radar Sensor
Your vehicle is equipped with a front radar sensor.

-
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.

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.
-
If the driver monitoring camera does not recognize the driver correctly, the DM may not monitor correctly.
Refer to Driver Monitoring Camera (Search).
-
After the DM has displayed the first message encouraging the driver to take a rest, it does not display it again during the following periods.
-
After displaying the warning pattern (caution), the next warning pattern (caution) is not displayed until 45 minutes have passed.
-

Emergency Lane Keeping (ELK) (Some Models)
Emergency Lane Keeping (ELK)
The ELK is a system designed to assist the driver’s steering wheel operation to avoid danger.
The ELK consists of the Blind Spot Assist function to prevent your vehicle from colliding with vehicles on adjacent lanes, and the Road Keep Assist function to prevent your vehicle from deviating from the road.
Refer to Blind Spot Assist (Search).
Refer to Road Keep Assist (Search).
Blind Spot Assist (Some Models)
The Blind Spot Assist function assists the driver in avoiding collisions with vehicles in adjacent lanes (excluding vehicles approaching in the opposite direction).
The Blind Spot Assist function detects white lines (yellow lines) on the vehicle lane using the Forward Sensing Camera (FSC) and detects vehicles on adjacent lanes using the rear side radar sensors. If there is a possibility of a collision with a vehicle in an adjacent lane when you try to change lanes or if you may deviate from your lane, it assists your steering wheel operation to keep you in the driving lane.
When the steering wheel operation assist operates, a warning sound and warning indications on displays alert the driver of the possibility of a collision. Furthermore, if the possibility of a collision increases, a warning sound and display indications alert the driver of the danger.

Do not rely completely on the Blind Spot Assist function and always drive carefully:
-
The Blind Spot Assist function has limitations. Do not rely completely on the system and always stay on course using the steering wheel.
-
The Blind Spot Assist function is not an autonomous driving system. In addition, the system is not designed to compensate for a driver’s lack of caution, and over-reliance on the system could lead to an accident.
-
The detection area of the camera and sensors is limited. If the steering wheel operation assist is operated without detecting a two-wheeled vehicle near the detecting vehicle, it could result in an accident.

How to use the projected vehicle path line function

-
(Screen display)
-
(Actual condition)
Make sure that there are no obstructions within the projected vehicle path lines.
Turn the steering wheel so that the projected vehicle path lines travel inside of the obstruction (A), and drive the vehicle forward until it passes the obstruction.
If the projected vehicle path lines are on an obstruction (B) or outside of the obstruction (C), the vehicle may contact the obstruction when turning the vehicle sharply.
-
The parking sensor detection range has limitations. For example, obstructions closing in from the side and objects short in height may not be detected. Always confirm the safety around the vehicle visually when driving.
For details, refer to the parking sensor obstruction detection indication and warning sound.
Refer to Parking Sensor System (Search).
-
Do not turn the steering wheel any more until the vehicle has passed the obstruction, even if the obstruction is not visible on the side view image. If the steering wheel is turned even more, the vehicle may contact the obstruction if it is turned sharply.
-
Because there might be a difference between the image displayed on the screen and the actual conditions, always check the safety of the surrounding area using the mirrors and directly with your eyes when driving.
-
Even though the object displayed on the screen, such as a road curb or a division line of a parking space, and the vehicle parallel guide lines appear parallel, they may not actually be parallel.

-
The following shows an example of vehicle parking with the steering wheel turned to the left while backing up the vehicle. When backing into a parking space from the opposite direction, the steering operation is reversed.
-
Back the vehicle into the parking space by turning the steering wheel so that the vehicle enters the center of the parking space.
-
(Screen display)
-
(Actual condition)
-
-
After the vehicle starts entering the parking space, stop and adjust the steering wheel so that the distance between the vehicle width lines and the sides of the parking space on the left and right are roughly equal, and then continue backing up slowly.
-
Once the vehicle width lines and the sides of the parking space on the left and right are parallel, straighten the wheels and back the vehicle slowly into the parking space. Continue checking the vehicle's surroundings and then stop the vehicle in the best possible position. (If the parking space has division lines, check whether the vehicle width guide lines are parallel to them.)
