SUBJECT

Models EQS-Class, S-Class (223 and 297 platform) 

Model Year 2021-2022 

Mercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2021-2022 EQS-Class and S-Class (223 and 297 platform) vehicles, the MBUX multimedia system software might not meet current production specifications. As a result, the central display might not be activated as intended when the vehicle is unlocked. In this case, the rearview camera image might not be displayed in the central display when the driver engages reverse gear. Instead, the central display would remain black. A deactivation or freezing of the rearview camera image during reverse driving can be ruled out. A rearview camera image that might not be available within 2.0 seconds (as required by FMVSS 111 S5.5.3) when beginning to back up might impair rear visibility, which might increase the risk of a crash. An authorized Mercedes-Benz dealer will update the MBUX multimedia system software on the affected vehicles.

Prior to performing this Campaign:

• VMI must always be checked before performing campaigns to verify that the campaign is required on a specific vehicle. Always check for any other open campaigns, and perform accordingly.
