Inside of vehicle

  1. Driver monitoring camera

    Refer to Driver Monitoring Camera (Search).

Front Side Radar Sensor (Some Models)

Front Side Radar Sensor (Some Models)

Front Side Radar Sensor

Your vehicle is equipped with front side radar sensor.

  1. Front side radar sensor

 

The following systems also use the front side radar sensor.

  • Front Cross Traffic Alert (FCTA)

The front side radar sensor function by detecting the radio waves reflected off a vehicle approaching from the front or an obstruction sent from the radar sensor.

 

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

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

    Refer to Exterior Care (Search).

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

  • For repairs or replacement of the front 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.

Close Note
View Note

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

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

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

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

The front 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).

Front Cross Traffic Alert (FCTA) (Some Models)

Traffic Jam Assist (TJA) (Some Models)

Close Proximity Warning

If your vehicle approaches the vehicle ahead while traveling under headway control using the Traffic Jam Assist (TJA), a warning sound is activated and a brake warning is indicated on the multi-information display. Check the surrounding conditions and keep a safe distance from the vehicle ahead.

  1. “Depress Brake Pedal” message is displayed

 

  • While the accelerator pedal is being depressed, the warnings and brake control do not operate even if your vehicle approaches the vehicle ahead.

  • In the following cases, the warnings and brakes may not operate even if your vehicle approaches the vehicle ahead.

    • Your vehicle is being driven at the same speed as the vehicle ahead.

    • Immediately after the Traffic Jam Assist (TJA) is set.

    • Immediately after the accelerator pedal is released.

    • Another vehicle cuts into the driving lane.

Lane-keep Assist System (LAS) (Some Models)

Lane-keep Assist System (LAS) (Some Models)

Lane-keep Assist System (LAS)

The LAS provides steering assistance to help the driver stay within the vehicle lane if the vehicle might be deviating.

The forward sensing camera (FSC) detects the white lines (yellow lines) of the vehicle lane in which the vehicle is traveling and if the system determines that the vehicle may deviate from its lane, it operates the electric power steering to assist the driver’s steering operation. The system also alerts the driver by displaying an alert on the multi-information display and the active driving display.

 

Use the system when you drive the vehicle on roads with white (yellow) lines such as expressways and highways.

 

Do not rely completely on the LAS:

  • The LAS is not an automated 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 functions of the LAS have limitations. Always stay on course using the steering wheel and drive with care.

  • Do not use the LAS under the following circumstances, otherwise it may result in an accident.

    • The vehicle is driven on slippery roads such as icy or snow-covered roads, and unpaved roads.

    • Tires of a different specified size are used, such as a temporary spare tire.

    • Tires with insufficient tread are used.

    • The tire pressures are not adjusted to the specified pressure.

    • The vehicle is being used to tow a camper or boat trailer.

    • Tire chains are used.

    • The vehicle is driven on roads with lane lines other than white (yellow) lines, such as an expressway.

Close Warning

The system may not operate normally under the following conditions.

  • A condition under which the forward sensing camera (FSC) cannot detect a target object is met.

    Refer to Forward Sensing Camera (FSC) (Search).

  • The visibility of white (yellow) lines is poor (due to paint flaking or dirt, or being hidden by vehicles ahead).

  • There are multiple white (yellow) lines or they are interrupted.

  • A misleading line on the road is picked up (such as temporary line for construction, shadow, lingering snow, or grooves filled with water).

  • The width of a lane is excessively narrow.

  • The vehicle is shaken after hitting a road bump.

  • The vehicle is driven on a section with a closed lane or temporary lane due to construction.

  • The vehicle is driven on a forked road or junction.

System Operation

Operation conditions

The Lane-keep Assist System (LAS) becomes operational when all of the following conditions are met.

  • The vehicle speed is about 64 km/h (40 mph) or faster.

  • The system detects white (yellow) lane lines.

 

When the system does not detect a white (yellow) lane line on one side only, the system does not operate on the side that is not being detected.

When temporarily canceling the system

The LAS goes on stand-by when any of the following conditions is met. The LAS is automatically restored when its operation conditions are met.

  • The system cannot detect white (yellow) lane lines.

  • The vehicle speed is less than about 56 km/h (35 mph).

  • The turn signal lever is operated.

  • The accelerator pedal is depressed abruptly.

  • The TCS/DSC is operating.

  • The TCS is turned off.

  • The steering wheel is operated.

  • The brake pedal is operated.

The function is temporarily stopped.

The LAS stops functioning in the following cases:

  • The temperature in the forward sensing camera (FSC) is too high or too low.

  • The windshield around the forward sensing camera (FSC) is foggy.

  • The windshield around the forward sensing camera (FSC) is blocked by an obstruction, causing poor forward visibility.

  • Strong light (such as sunlight, or headlights (high-beam) of on-coming vehicles) is directed at the forward sensing camera (FSC).
