Key operated
The central locking system consists of a control unit with a pulse circuit, servomotors in the doors, a servomotor in the trunk lid or in the rear lid, and a servomotor in the fuel tank cap. Control is carried out by two microswitches, which are located in the driver's door lock.
Additionally, the central lock has an anti-theft device that can only be activated through the lock in the driver's door. To do this, the key must be turned back to the "close" position no later than 10 seconds after the closing signal. When the anti-theft device is activated, the following are mechanically blocked: the lock drum in the driver's door and the electric servomotors in the other three doors.
The trunk can be locked by turning the key to the left and removing the key in this position. However, after unlocking the doors, the trunk remains locked. In order to provide access to the car after an accident, a shock switch is installed in the control unit, which unlocks all doors after a collision of a certain force.
Tips: To ensure the operation of the shock switch, the control unit must be firmly secured to the vehicle.
Emergency control
If the central lock needs to be removed, the doors and the boot lid or the rear lid can also be opened and closed with the key in the traditional way. The door lock buttons can also be pressed by hand if the central lock is not set to the "locked" position.
However, releasing the fuel filler cap is more complicated: after removing the right-hand boot trim, you need to pull the locking lever on the fuel filler cap servomotor back in the direction of travel.

If the central lock is set to the "locked" position, it can only be unlocked using the key in the driver's door lock or the central lock release button. The passenger doors next to the driver and the rear doors in the "locked" position cannot be unlocked manually.
Using the remote control
The radio remote control can be used to control the central lock, switch the locking module on and off, and activate the anti-theft system. For more information, see the section "Anti-theft system".
