Rear Door Security Locks; Lockout Protection - Chevrolet Malibu 2010 Owner's Manual

Rear Door Security Locks

The vehicle has rear door security locks to prevent
passengers from opening the rear doors from the inside.
To set the locks, insert a key into the slot and turn it to
the horizontal position. The door can only be opened
from the outside with the door unlocked. To return
the door to normal operation, turn the slot to the vertical
position.
Open the rear doors to
access the security locks
on the inside edge of
each door.

Lockout Protection

If you press the power door lock switch when the key is
in the ignition and any door is open, all the doors will
lock and then the driver's door will unlock. Be sure
to remove the key from the ignition when locking your
vehicle.
If the remote keyless entry transmitter is used to lock
the doors while the key is in the ignition, a chime
will sound three times. All doors will then lock.
