Seatbelt Reminder
Someone hasn’t buckled up — or the sensor thinks they haven’t.
What it means
A red icon of a seated person with a diagonal belt across them, often with an audible chime. The weight sensor in a seat has detected someone sitting there (or a heavy bag) and the corresponding seatbelt hasn’t been fastened. Some systems also monitor the rear seats.
What to do
- 1Make sure every occupied seat has its belt clicked in properly.
- 2If the light stays on with the belt fastened, try unbuckling and re-buckling a few times — the buckle switch may be sticky.
- 3If a heavy shopping bag is on the seat, move it to the boot or footwell to stop the sensor triggering.
- 4Persistent false alarms usually mean a failed buckle or seat sensor — book it in.
Likely causes
- •Seatbelt not fastened
- •Heavy object on an unoccupied seat
- •Faulty seatbelt buckle switch
- •Failed seat occupancy sensor (the pressure pad in the seat base)
