How do you reset the srs light on 99 s70?

To reset the SRS (Supplemental Restraint System) light on a 1999 Volvo S70, you typically need to use a scan tool that can communicate with the vehicle's airbag system. Alternatively, you can disconnect the negative battery terminal for about 10 minutes, then reconnect it. However, this method may not always work, as the SRS light often requires specific diagnostic procedures to clear. Always consult your vehicle's service manual or a professional for safety and accuracy.
