Seat belt light
This light is normally a reminder that a belt is unfastened. When it stays on with the belt fastened, or appears alongside an airbag warning, it is reporting a fault in the restraint system rather than reminding you of anything.
Common triggers
A belt genuinely unfastened, or an occupancy sensor detecting weight on a seat with an unfastened belt
A worn buckle switch that no longer reports the belt as latched
A restraint system fault, particularly if the airbag warning is lit at the same time
What to check
Fasten and unfasten each belt in turn and watch whether the light responds
Check for items left on a seat, which can trigger the occupancy sensor
Pull each belt sharply and confirm it locks — a belt that does not lock will not restrain an occupant
Have the restraint system scanned if the airbag warning is lit as well

Frequently asked questions
The light stays on with my belt done up — does that matter?
It can. A buckle switch fault is minor, but the same warning can accompany a restraint system fault, which affects whether the belt and airbag work together correctly in a crash.
Why does it come on when a bag is on the passenger seat?
The occupancy sensor detects weight and expects a belt. Moving the item to the footwell or boot resolves it.
