On certain vehicles, the occupant classification system (OCS) may not work properly due to a software error. This could cause the airbag system to turn off the passenger-front airbag, even if an adult is seated in the front passenger seat.
An airbag that is turned off could increase the risk of injury to a passenger in a crash.
Mercedes-Benz will notify owners by mail and instruct you to take your vehicle to a dealer to update the airbag control unit software.
