Active Bonnet

Active Bonnet precautions (Some Models)

Active Bonnet precautions (Some Models)

In the unlikely event that the vehicle were to hit a pedestrian and a certain amount of impact is applied to the front of the vehicle, impact to the head of the pedestrian if it were to hit the bonnet is lessened by the rear area of the bonnet raising instantly to maintain a wide space between it and the parts in the engine compartment. If the sensor installed to the back of the front bumper detects a certain amount of impact by a collision with a pedestrian or other obstruction while the vehicle is being driven at a speed sufficient to activate the system, the system is activated and the bonnet is raised.

 

If the active bonnet has activated, always consult an expert repairer, we recommend an Authorised Mazda Repairer.

If the bonnet release handle is pulled after the active bonnet has activated, the bonnet will rise even further. If the vehicle is driven with the bonnet raised it will obstruct visibility and could result in an accident. In addition, do not attempt to push the bonnet back down. Otherwise, it could deform the bonnet or cause injury because the activated bonnet cannot be lowered manually. Before driving the vehicle to an expert repairer, we recommend an Authorised Mazda Repairer after the active bonnet has activated, make sure that the raised bonnet does not obstruct vision and drive the vehicle at a low speed.

Do not touch the actuator directly after the active bonnet has activated. Otherwise, it could result in a burn as the actuator is hot directly after the activation.

Operation and Handling

  • Always make sure that the bonnet is closed completely before driving. Otherwise, the system may not operate normally.

  • The system may not operate for about 8 seconds after the ignition is switched ON.

  • Use tyres of the same specified size and appropriate pressure, without abnormal wear on all 4 wheels. If tyres with abnormal wear, different sizes, or inappropriate pressure are used, the system may not operate normally.

  • If something hits the area around the front bumper, the sensor could be damaged even if the active bonnet does not activate. Always consult an expert repairer, we recommend an Authorised Mazda Repairer to have the vehicle inspected.

  • Do not remove or repair parts or wiring for the active bonnet. In addition, do not test the system’s circuitry using an electric tester. Otherwise, the active bonnet may activate mistakenly or not operate normally. Consult an expert repairer, we recommend an Authorised Mazda Repairer for when repairs or replacement servicing is required.

  • Do not replace the front bumper, bonnet, suspension, or aero parts with non-genuine Mazda parts. Otherwise, the system may not operate normally.

  • Do not install non-genuine Mazda accessories to the front bumper. In addition, do not install objects on the bonnet. Otherwise, the system may not operate normally.

  • Do not close the bonnet excessively or apply a load to the actuator. Otherwise, the actuator could be damaged and cause the system to not operate normally.

  • Do not modify the suspension. If the vehicle height or the damping force of the suspensions is changed, the system may not operate normally.

  • When equipping parts, consult an expert repairer, we recommend an Authorised Mazda Repairer. If parts are installed incorrectly, the active bonnet may not activate normally due to the inability to detect an impact.

  • When disposing of the vehicle, consult an expert repairer, we recommend an Authorised Mazda Repairer. If the vehicle is not handled correctly, it could result in injury.

  • The active bonnet cannot be reused if it has been activated. Have the system replaced at an expert repairer, we recommend an Authorised Mazda Repairer.

How the Active Bonnet Works

How the Active Bonnet Works

If the Active Bonnet Activates, Does Not Activate

If the active bonnet activates

The active bonnet activates under the following conditions:

  • If the front of the vehicle hits a pedestrian or obstruction while the vehicle is being driven at a speed sufficient to activate the system, the system will activate if a certain amount of impact is applied in a collision even though no trace may remain on the front bumper. In addition, it may activate depending on the level of impact from even a light object, small animal, or other small object.

  • The system may also activate if the lower part of the vehicle or the front bumper receives an impact from one of the following situations:

    • The vehicle hits a curb.

    • The vehicle falls into a deep ditch or hole.

    • The vehicle bounces and hits the ground.

    • The front, bottom part of the vehicle contacts the slope of a parking garage, the surface of an even, undulating road, or a protruding or fallen object on the road.

Situations in which the active bonnet may not activate

The active bonnet may not active in the following situations as an impact would be difficult to detect.

  • The pedestrian gets hit at an angle or by the side areas on the left and right of the front bumper.

  • The vehicle hits a pedestrian who is carrying something such as a bag which can absorb the impact.

Situations in which the system does not activate

The active bonnet does not activate under the following conditions:

  • The front bumper gets hit while the vehicle is being driven at a speed insufficient to activate the system.

  • The vehicle gets hit from the side or the rear.

  • The vehicle rolls or turns over (the active bonnet may operate depending on the accident conditions).
