RepairPal Expert Overview
The passenger frontal air bag may not deploy as needed in a crash due to a fault within the Occupant Classification System (OCS). The OCS may not properly detect an adult in the passenger front seat, instead classifying the passenger as a child. When the OCS does this, it prevents the passenger frontal air bag from deploying, attempting to protect child occupants. As a result, there is an increased risk of injury to adult passengers.
Recall repairs on your Mercedes Benz vehicle must be performed by a Mercedes Benz dealership. Mercedes Benz will notify known owners of affected vehicles beginning in January 2017. If you do not receive a notification, but wish to check to see if your vehicle is included, please contact one of your local Mercedes Benz dealerships. They will also check for any other incomplete recalls on your vehicle. For best results, be prepared to provide your Vehicle Identification Number (VIN) to the service department consultant you speak with.
The occupant classification system (OCS) may disable the passenger frontal air bag in error when an adult is sitting in the passenger front seat. Dealers will update the OCS software free of charge to resolve the concern.
