Volvo 2006 C70 - Manual (Page 88)

The doors cannot be opened by pulling up the lock button.
If both doors are closed when a lock button is pressed, the alarm will not be armed.
Each door can also be locked manually using the lock button on that particular door. This applies only if the car has
not been locked from the outside.
The doors can also be unlocked (and the door opened) by pulling the handle in the door twice.
Locking the doors when leaving the vehicle
The lock switches in the doors can also be used for locking all doors when leaving the vehicle. However, please be
aware of the following:
If one or more of the doors is open and the key is not in the ignition when the button is pressed, the doors will lock
automatically when they are closed. This will also arm the alarm.
If the key is in the ignition and one of the doors is open, the vehicle cannot be locked using the buttons on the
doors.
