Active Bonnet
*Some models.
Active Bonnet precautions *
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 suf ¿ cient to activate the system, the
system is activated and the bonnet is raised.

WARNING
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.

Active Bonnet
CAUTION
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 speci ¿ ed size on all four wheels. If tyres with different sizes 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, aero parts, or wheels 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
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 suf ¿ cient 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 dif ¿ cult
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 insuf ¿ cient 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
