The OCS is a system that figures out if there's an occupant in a seat based on the amount of weight being exerted on a sensor, and will arm or disarm the airbags accordingly. The affected models – SL550, SL63 AMG and SL65 AMG – might not detect a very light person, which could increase the chance of injury were the car to get in a wreck.
Naturally, Mercedes will be notifying owners and replacing the passenger-side OCS free of charge. Take a look below for the bulletin from NHTSA.
Mercedes-Benz (Mercedes) is recalling certain model year 2013 SL63, SL550, and SL65 vehicles manufactured January 16, 2013, through April 30, 2013. The affected vehicles are equipped with an occupant classification system (OCS) that may not detect a very light person sitting in the front passenger seat.
If the OCS does not detect a very light person sitting in the seat, the passenger side air bag would be turned off. In the event of a crash necessitating side air bag deployment, the passenger would be at an increased risk of injury.
Mercedes will notify owners, and dealers will replace the passenger side seat cushion including the OCS. The recall is expected to begin in December 2013. Owners may contact Mercedes at 1-201-573-0600.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
