Re: How to Reset Service Light[850/94] posted by David Emanuel on

The service light stays on until you reset it. It is (from what I understand) a reminder switch. It always seems to come on at the most inopportune time for me. To reset the switch, follow the instructions below, completely and carefully. It is important to do it quickly and not let any time lapse after each blinking of the light, or else you will have to start over and do this procedure several times. At least that's what I've found with my car. Cut and paste these instructions to a test file and print them out...then keep that in your glove box. This is most helpful. ---Dave
