The occupant classification system for the front passenger seat may not be calibrated in accordance with the specifications. Consequently, an installed child seat may be identified as a person or a small, light person as a child seat.
As a result, the passenger airbag could be activated despite the presence of a child seat or the passenger airbag could fail to activate despite the presence of a person on the passenger seat, increasing the risk of injuries.
The Mercedes-Benz B-Class models affected by this recall were manufactured between 28 August 2014 and 2 November 2017.
