Behaviour In The Case Of Servicing

When removing:
- vehicle battery
- alarm siren
- alarm control centre

an activated tilt sensor will trigger an alarm. In order to carry out servicing work, the alarm siren must be switched off before starting the work. To switch it off, insert the vehicle key with valid transponder into the ignition lock and rotate to actuate the buzzer contact. Components can be removed without triggering the alarm as long as the vehicle key remains inserted.
