Triggering The Alarm

If the alarm is in activated mode and the central electronic module (CEM) receives an indication from a sensor, an alarm cycle is started. An alarm cycle means that the siren starts sounding and the turn signal indicators start flashing. The siren sounds for 30 seconds and then stops. However, the turn signal lamps continue to flash for approximately a further 5 minutes.
