Why does the air bag warning light come on in a Citreon Picasso?

The airbag warning light in a Citroën Picasso may illuminate due to several reasons, including a malfunction in the airbag system, a faulty sensor, or a problem with the seatbelt system. It could also indicate a loose connection or a fault in the control module. It's essential to have the vehicle diagnosed by a professional to ensure the airbag system is functioning correctly for safety. Ignoring this warning can lead to airbag deployment issues in the event of an accident.
