Central Locking Button
The central lock button in the center console provides a momentary ground input signal to the GM. This input initiates a single lock for each door and the trunk. The fuel filler flap remains unlocked for refueling purposes.
If a door is manually opened while centrally locked, the remaining doors stay locked.
The opened door can be re-locked when closed by manually locking or pushing the central button twice. This allows the locks of the remaining doors to be re-synchronized again.
The central button is now located in a combined housing with the hazard flasher switch.
