Flight safety warning indicator turned on

Kindly find the snapshot attached. Can someone give me some pointers?


Class 2.1 C-DI W204 from 2011

It was getting old spending so much on repairs. Hoping it's just a little issue that I can resolve on my own

Many thanks

Is the alert always on? If the front passenger isn't there, it makes no difference.

There are just too many potential problems; fault codes must be read.

This is a great response. Yes, it will last forever. Passenger presence makes no difference.

It may be difficult to "guess" this without reading the codes, as previously mentioned.

Reading the codes is necessary for determining the source of the problem, as mentioned earlier.


'Sensor mat' or front passenger seat occupancy sensor failure is a typical issue. One more is a broken seatbelt buckle. A defective electrical hookup beneath the front passenger seat is an additional issue. However, there are other alternative explanations.

However, unless you're handy with a wrench, this is not a problem that a do-it-yourselfer should attempt to fix.

(To test whether the error code returns, you might use a scanner such as iCarsoft to delete it; nevertheless, it is quite likely that it will return.)
