If the restraint systems trigger, the MRS control unit sends a message to other control units. The following functions are performed by the relevant control units depending on the severity of the accident:

• Switching off the electric fuel pump (via the Digital Motor Electronics control unit)
• Switching off the alternator (via the Digital Motor Electronics control unit)
• Opening the central-locking system (via the junction box electronics)
• Switching on the interior lighting (via the footwell module)
• Switching on the hazard warning lights (via the footwell module)
