System Overview: Acknowledgments
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.
The turn signal lamps give a long flash to confirm that the car is fully locked. They flash twice when the car is unlocked. The customer can decide whether the acknowledgment is activated or not via the menu system in the infotainment control module (ICM).
