SOURCE: how to reset srs light
'Supplemental Restraint System' MIL must be reset with Mercedes dedicated scanner.
This is not a DIY job unless you have such a scanner.
It is often triggered by the battery voltage dropping below 10.5 vdc. This often is due to undercharged battery or weak/old battery. Other cause is battery disconnect with ignition in the RUN position.
Finally, also caused by wiring problem such as steering wheel 'clock spring cassette' or 'squib' failure...another specialist job.
Ain't electronics fun?
BTW..WARNING : Don't mess with the steering wheel unless you know how to deactivate the drivers air bag.(SRS)
It will cause severe injury should it deploy and people have been killed by air bags going off even out of the vehicle.
