How to Reset the Airbag Light on a Mercedes SLK

Model: Mercedes Slk MK 2, R171 - Years 2004-2011
Part: Warning light – error code

In this video tutorial, you can see how to reset the passenger airbag light on a 2004 Mercedes SLK. Airbags are crucial for the safety of the driver and can be activated or deactivated, but caution is necessary. This activation or deactivation of the passenger airbag can be checked via warning lights (?PASSENGER AIR BAG ON? and ?PASSENGER AIR BAG OFF?). When you press the start/stop button once or twice, the system performs a self-check. The ?PASSENGER AIR BAG ON? light may illuminate for about 60 seconds, indicating that the passenger airbag can activate in the event of an accident. Alternatively, the ?PASSENGER AIR BAG OFF? light may illuminate, indicating that the passenger airbag is deactivated and will not activate in the event of an accident. To reset the airbag light if it has illuminated, you need to connect a diagnostic device via cable to your vehicle and follow the reset procedure as shown in the video.
