How can you reset the airbag warning light on a 2016 Mercedes-Benz C-Class after servicing?

Step 1: Safety First

• Ensure that the vehicle is in Park (P) and the parking brake is engaged.
• Make sure the service on the airbag system has been completed correctly by a qualified technician.

Step 2: Using the OBD-II Scanner

• Connect an OBD-II scanner to the vehicle's OBD-II port, which is usually located under the dashboard on the driver's side.
• Power on the OBD-II scanner and wait for it to initialize.

Step 3: Accessing Airbag System Codes

• Navigate through the OBD-II scanner menu to find the "Airbag" or "SRS" code section.
• Read the stored codes in the airbag system to verify the issue has been properly resolved.

Step 4: Clearing the Codes

• Select the option to clear or reset the codes. Confirm your selection if prompted.
• Wait for the scanner to complete the process. This usually takes a few seconds.

Step 5: Verifying the Reset

• Turn off the ignition and disconnect the OBD-II scanner.
• Turn the ignition back on and check the dashboard to see if the airbag warning light is still illuminated.
• If the light is off, the reset was successful. If the light is still on, further diagnostics may be needed.

Step 6: Manual Reset (If Equipped)

• While sitting in the driver's seat, turn the ignition key to the "ON" position without starting the engine.
• Wait for the airbag warning light to turn off (usually about 7 seconds) and immediately turn the ignition off within 1 second after the light goes off.
• Repeat the process at least two more times – turn the ignition on, wait for the airbag light to go off, then quickly switch off the ignition.
• After the third time, start the engine and check if the airbag warning light is no longer illuminated.
