2021 Mercedes-Benz Models Incorrect Operator's Manual TSB
Mercedes-Benz has launched Service Campaign 2022030014 to correct printed operator's manuals in various 2021 models, including the AMG GT. The manuals may contain inaccurate information regarding the radar sensor MMRV1, requiring a dealer check and replacement.

Mercedes-Benz has initiated Service Campaign 2022030014 to address a potential issue with the printed operator's manual in various 2021 models. This campaign ensures that owners receive accurate and up-to-date information for their vehicles, including the Mercedes-Benz AMG GT manual.
Why This Matters
The manufacturer, Mercedes-Benz AG ("MBAG"), has identified that certain 2021 model year vehicles may have operator's manuals containing incorrect information about the radar sensor MMRV1. This discrepancy means the printed manual may not align with the vehicle's internal specifications, which is a compliance concern.
What's Being Addressed
Service Campaign 2022030014, also identified by campaign description 21P5892203, focuses on checking and, if necessary, replacing the printed operator's manual. The core problem lies with potentially inaccurate details regarding the radar sensor MMRV1, which could lead to confusion or misunderstanding for vehicle owners.
How to Check if Your Vehicle is Affected
This service campaign applies to 44,425 vehicles from the 2021 model year. The affected models include the CLA-Class, GLA-Class, GLE-Class, GLS-Class, A-Class, C-Class, E-Class, GLB-Class, CLS-Class, and AMG GT 4-doors/Coupe. These vehicles are built on platforms 118, 167, 177, 190, 213, 238, 247, 257, and 290.
Your authorized Mercedes-Benz dealer will be able to check your vehicle's status in the Vehicle Master Inquiry (VMI) system, where affected vehicles will be flagged as "OPEN" for this campaign.
Manufacturer's Remedy
Mercedes-Benz USA (MBUSA) will conduct this service campaign through its authorized dealer network. Dealers will inspect the printed operator's manual in affected vehicles. If the manual is found to be missing or contains the incorrect information, it will be replaced with the correct version.
This remedy is available and will be performed as necessary, ensuring that all owners have an accurate Mercedes-Benz AMG GT manual or manual for their specific model.
