What do you mean by dismantle? Remove the airbag module?
The airbag module on a 2003 Mercedes Vito is typically located underneath the front passenger seat. To access it, you may need to remove the seat, as the module is mounted on the vehicle's floor. Always ensure the battery is disconnected before attempting to work on the airbag system for safety reasons.
