Chevrolet Sonic Owner's Manual: Delayed Locking
This feature delays the actual locking of the doors until five seconds after all doors are closed. Delayed locking can only be turned on when the Unlocked Door Anti Lockout feature has been turned off.
When 
is pressed on the driver or
passenger door power lock switch while the door is open, a chime will sound three
times to indicate that delayed locking is active. The doors will then lock automatically
five seconds after all doors are closed.
If a door is reopened before five seconds have elapsed, the five second timer
will reset once all the doors are closed again. Press
on the door lock switch again, or press
on the RKE transmitter, to override
this feature and lock the doors immediately.
Delayed locking can be programmed through the Driver Information Center (DIC). See Vehicle Personalization.
