i-ACTIVSENSE

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.

  

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 vehicle is driven on roads other than expressways and highways.

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

Operation conditions

The Blind Spot Assist function becomes operational when all of the following conditions are met.

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

• The vehicle is driven on a straight road or gentle curve.

• The system detects white (yellow) lane lines on both sides.

• There is a vehicle on the rear sides.

• The Blind Spot Assist function may not operate normally when any of the following conditions is met.

  • 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 vehicles in adjacent lanes is poor.

  • A vehicle in an adjacent lane rapidly approaches at a high speed.

  • Vehicles in adjacent lanes have any of the following shapes.

    • The vehicle size is very small.

    • The vehicle height is extremely low or high.

    • A special type of vehicle with a complex shape.

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

  • There are multiple white lines (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 the vehicle lane is narrow or wide.

  • 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.

• When the ELK OFF indicator light is on, the system is canceled according to a Mazda Connect setting.

  Refer to the Settings section in the Mazda Connect Owner's Manual.

Temporary cancellation of the function

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

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

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

• The accelerator pedal is depressed abruptly.

• The brake pedal is depressed.

• The steering wheel is operated abruptly.

• The TCS/DSC is operating.

• The TCS/DSC is turned off.

• Multiple vehicles are traveling in the detecting area near your vehicle.

Cancellation of the function

The Blind Spot Assist function is canceled when any of the following conditions is met.

• The temperature in the Forward Sensing Camera (FSC) is high or 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.

• Snow, ice, or mud is adhering around a rear side radar sensor.

• The temperature around a rear side radar sensor is high.

• There is a problem with the system.

System problem

If there is a problem with the system, the i-ACTIVSENSE warning indication/warning light turns on and a message is indicated.

Refer to i-ACTIVSENSE Warning Indication/Warning Light (Search).

Steering wheel operation assist

If there is a possibility of collision with a vehicle in an adjacent lane when you try to change lanes or if you may deviate from the lane, the steering wheel operation assist operates.

While the steering wheel operation assist is operating, the system notifies the driver using a warning sound, multi-information display, and the active driving display that it is assisting the steering wheel operation.

• If the driver operates the steering wheel while the steering wheel operation assist is operating, the steering wheel operation assist is canceled.

• When the steering wheel operation assist is performed several times within a certain period of time, the warning sound is activated.
