The Road Keep Assist function assists the driver in avoiding a departure from the road while driving.

The Road Keep Assist function recognizes the outside of the road using the Forward Sensing Camera (FSC). If your vehicle may be deviating from the road, it provides steering assistance to avoid departure from the road.

When the steering wheel operation assist operates, display indications alert the driver of the possibility of a road departure. Furthermore, if the possibility of a road departure increases, a warning sound and display indications alert the driver of the danger.

 

---

Do not rely completely on the Road Keep Assist function and always drive carefully:

• The Road Keep Assist function has limitations. Do not rely completely on the system and always stay on course using the steering wheel.

• The Road Keep 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.

Do not use the system under the following conditions. Otherwise, it may result in an accident:

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

• Tires other than the specified size are used, such as when tire chains or temporary spare tires are used.

• The vehicle is towing a camping trailer or boat trailer.

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.
