Why did my SRS light stay on after I turned on the car?

The 'SRS' light is showing you that a trouble code is stored for the supplemental restraint system. A qualified repair shop needs to scan the body control module on your car and find out the what problem(s)is/are.

It is on because there is a problem with the SRS. Take it to a dealer for repair, immediately. Do not attempt to repair yourself. Serious injury can occur if not done correctly.
