EU safety alerts
Safety Gate, the European Union's rapid alert system, names the Mii in 5 alerts. European versions can differ from the North American car.
The towing eye supplied with the car may have defective welding. If the towing eye is used, it may break with the risk that the towing cable hits people.
The front trim of the sun roof may not be securely stuck down. As a result, the sun roof's front trim frame could become detached posing a risk to following traffic.
There is a possibility that the locking lever of the manual child lock was damaged during manufacturing. This can lead to the child lock deactivating without being noticed, especially in the event of strong vibrations.
The airbag might not deploy correctly due to a fault in the gas generator welding process.
Incorrectly parameterised airbag control units may have been fitted. For these airbag control units, the diagnosis function of the side crash sensors is deactivated. Should a fault occur in the side airbag system, the fault would not be recognised and the airb…
