The official notice
Defect
On certain vehicles, the passenger seat belt assemblies may contain defective automatic locking retractors (ALR). As a result, the seat belts may not properly lock to secure a child seat. Note: The vehicle's lower universal anchorage system (UAS) is not affected by this defect and may still be used to secure a child seat.
Safety Risk
A seat belt that is used to secure a child restraint but is not properly locked could increase the risk of injury in a crash.
Remedy
Mercedes-Benz will notify owners by mail and instruct you to take your vehicle to a dealer to inspect the seat belts. They will be replaced, if necessary.
