IMPORTANT NEW RECALL INFORMATION
This Recall Campaign is being launched today and the 130 affected vehicles are flagged in VMI.
On Friday, November 1, 2013 dealers were notified that Mercedes-Benz USA, LLC (MBUSA) will conduct a voluntary
Recall Campaign on approximately 130 Model Year 2013 SL-Class (231) vehicles with regard to the front passenger seat
occupant classification system. This notification is posted on the NHTSA website and may generate some customer
questions.

Owner Notification - Owner notifications will be sent on December 30, 2013.
Parts - Dealers may order parts via your facing PDC. See parts table in Dealer Repair Bulletin which identifies
required part number by VIN. Be sure to include the required upholstery color code. Parts are in very limited
supply and should not be ordered for shelf stock. Parts replacement rate is 100%.
Background
The OCS detects whether a child seat is installed, or a person is sitting in the passenger seat. When the OCS detects
either a child seat or that the front passenger seat is not occupied, the front passenger airbag is automatically
deactivated . On a limited number of SL-Class vehicles (231 platform} produced between January 16, 2013 - April 30,
2013, the passenger seat OCS may fail to properly detect an occupant in the front passenger seat and it could
erroneously deactivate the front passenger side airbag. This may result in an increased risk of injury in the event of a
crash . However, in such a case the "PASSENGER AIR BAG OF F" indicator lamp in the center console of the vehicle would
be illuminated to indicate this condition.
MBUSA therefore has initiated a voluntary recall of all potentially affected vehicles described above . The recall will be
conducted to replace the front passenger seat base in the subject vehicles.

Given this notice, it is a violation of Federal law for a dealer to deliver any new or used Model Year 20 13 SLClass (231) covered by this notification in dealer inventory, for sale or lease, until the vehicle has been repaired.
A copy of the campaign bulletin is attached, and may also be found on StarTeklnfo.
When scheduling customers for an appointment please ensure that you are aware of any open campaigns in VMI so that the
customer is advised about the time necessary to complete all campaigns.
Note: VMI must always be checked before performing campaigns to verify that the campaign is required on a specific vehicle.
Dealers may also identify vehicles subject to a campaign through NetStar by selecting "Campaign " under the Controlling tab.
Only vehicles that have been retailed by the respective dealer will be displayed within this program.
While we regret any inconvenience this may cause, MBUSA is determined to maintain a high level of vehicle quality and
customer satisfaction.
Please refer all customer inquiries to the Customer Assistance Center at 1-800-FOR_MERCedes ( 1-800-367-6372).

TO :
SUBJECT:

Model 231 (SL Class), Model Year 2013
Replace Front Passenger Seat Occupant Classification System

Daimler AG (DAG), the manufacturer of Mercedes-Benz vehicles, has determined that on a limited
number of SL-Class vehicles (231 platform) the Occupant Classification System (OCS) may not function
properly. The OCS detects whether a child seat is installed, or a person is sitting in the passenger seat.
When the OCS detects either a child seat or that the front passenger seat is not occupied , the front
passenger airbag is automatically deactivated. On a limited number of SL-Class vehicles the passenger
seat OCS may fail to properly detect an occupant on the front passenger seat and it could erroneously
deactivate the front passenger side airbag . This may result in an increased risk of injury in the event of a
crash.
MBUSA therefore has initiated a voluntary recall of all potentially affected vehicles described above. An
authorized Mercedes-Benz dealer will replace the front passenger seat base in the subject vehicles.

Please note that Recall Campaigns do not expire and may also be performed on a vehicle with a vehicle
status indicator.
