Triggering The Alarm
WARNING: This page is about a different car, the 2010 Volvo V70, 2009 Volvo V70, and 2008 Volvo V70. However, it is still accessible from the selected car via links, so may be relevant.
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.
