A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Mercedes\-Benz AG \(“MBAG”\), the manufacturer of Mercedes\-Benz vehicles, has determined that on certain MY 2022\-2023 EQS \(297 platform\) vehicles, the software for various control units does not meet current specifications. An extensive optimization update will be implemented on the affected vehicles. Also, a special procedure has already been implemented in Xentry. The software updates will include, but are not limited to, increased system robustness, increased augmented reality camera quality, implementation of the Zync\-App for video streaming via the head unit, and implementation of Dolby Atmos for an improved audio experience. MBUSA will conduct a service campaign. An authorized Mercedes\-Benz dealer will update the control units.
