If an unauthorized attempt is made to open one of the doors, the hood or the trunk, the siren is triggered for 30 seconds and the ignition is switched off. At the same time, the hazard warning light system is switched on for 5 minutes, the low beam flashes in the rhythm of the hazard warning light system.
If unauthorized actions continue, attempts are made to start the engine, remove the car radio, manipulate the glove compartment or battery, the siren is turned on again for 30 seconds.
When attempting to move the vehicle after a short distance, a siren sounds.
Turning the siren on and off occurs simultaneously with the switching on and off of the anti-theft device via the door lock or remote control system.
When the system is turned on, the LED in the center console lights up for 36 hours.
If the LED blinks when the system is turned on, then either the doors, engine hood, trunk lid, or glove compartment are not completely closed. When the system is turned on, the LED blinks if one of the side windows is open more than the permissible distance. If it is not closed, the system takes everything that is completely closed into protection after 10 seconds and the LED lights up constantly.
When the system is turned off, the LED goes out. If the system is turned off after the LED goes out, (after 36 hours), then it flares up again for a short time.
If the alarm is triggered, the LED flashes for 36 hours, thus indicating an attempt to break into the car or steal it. It goes out after the system is turned off.
Trunk is also available when the system is activated. The LED flashing (10 seconds) should draw your attention to the fact that the trunk lid, although closed, is not locked (turn the key to the right and remove it).
Anti-theft alarm with additional interior protection and a sensor that responds to changes in the vehicle's tilt angle
If the rear or one of the side windows is broken (all side windows must be closed, however, for ventilation of the cabin in hot weather they can remain open by 10 mm)- a siren sounds. The system also reacts if the position of the car changes, for example, during unauthorized attempts to dismantle the wheels or tow - a sensor is triggered by a change in the angle of the car.
If one of the side windows is slightly open more than the permissible value, the LED blinks. If it is not closed, the system takes all closed windows into protection after 10 seconds and the LED lights up constantly.
To prevent unwanted alarm activation from the tilt sensor, for example when transporting by train, ferry, etc., the sensor can be switched off.
Immediately after turning on the anti-theft alarm, repeat the process of turning it on again (i.e. turn the key again to the anti-theft system on position or, if using remote control, press button 2 briefly).
The LED goes out and lights up again. Now the sensor is off until the next complete shutdown of all alarms.
Please note: Incorrect installation of speakers in doors may adversely affect the operation of the window protection device.
If normal shutdown of the system is not possible, then in an emergency the following steps should be taken:
- open the door with the key (the siren goes off for 30 seconds);
- get into the car, close the door and turn the ignition key to position 1 (again, the siren goes off for 30 seconds);
- wait until the LED goes out (after approx. 15 minutes)
Do not open the door during this time; the ignition key remains in position 1. After this, the system is disabled.
