Location of the central locking elements on the front door
The vacuum from the engine intake manifold is fed to the vacuum accumulator located in the luggage compartment, and from it to the system devices through a switch located on the left front door.
The vacuum accumulator enables tenfold locking of the locks when the engine is not running, after which the locking can be done manually if necessary (for example, if the engine does not start).
