TO:	ALL MERCEDES-BENZ CENTERS
SUBJECT:	Model EQS-Class and S-Class (223 and 297 platform) Model Year 2021-2022 Calibration of Ambient Lighting

 

Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz, has determined that on certain MY
2021-2022 EQS-Class and S-Class (223 and 297 platform) vehicles, an incorrect calibration of the LED

selects settings with a green color. MBUSA will conduct a service campaign and an authorized Mercedes-
Benz dealer will re-calibrate the ambient lighting to remedy the topic.

 

Prior to performing this Campaign:

• VMI must always be checked before performing campaigns to verify that the campaign is required on
