General information
All models are equipped with an immobilization device that effectively prevents unauthorized attempts to start the engine. The system is activated by the ignition key and an electronic sensor built into the ignition lock.
The anti-theft system control unit monitors the status of all doors, including the tailgate / tailgate, hood and ignition lock, as well as interior and luggage compartment volumes and vehicle roll using contact and volumetric sensors (see illustration The layout of the elements of the anti-theft system). The control unit is installed at the bottom of the right front pillar at the passenger's feet and is covered with a decorative panel. Ultrasonic (voluminous) sensors are installed in the upper part of the central pillars and react to any changes in the interior volume. Tilt sensors respond to changes in vehicle roll even when trying to remove the wheel. The main signal siren of the anti-theft system is installed on the left on the bulkhead of the engine compartment under the hood, an additional siren is installed under the left front fender. On Universal and Zafira models, the glass condition sensor is installed in the luggage compartment, closer to the rear side window.
