Engine fault warning light (check engine)
Urgency: Garage soonYellow or amberSymbol: outline of an engine seen from the side, in yellow or orange
The orange engine-shaped warning light comes on when the ECU detects a fault affecting combustion or emissions. If it flashes, it usually points to misfires that can damage the catalytic converter.
What to do: If it stays on steadily, you can drive gently to a garage and ask for a fault code read-out. If it flashes or you notice a loss of power, slow down and get to a garage as soon as possible.

Seatbelt fault warning light or message
Urgency: Garage soon

What to do: Ask for the seatbelt and pretensioner system to be checked at a garage with the right diagnostic equipment, and check whether any manufacturer campaign is outstanding for your vehicle.
