Lockout Protection; Leaving Your Vehicle - Chevrolet 2003 Monte Carlo Owner's Manual

Mode 4: Automatic all-door lock when the transaxle is
shifted out of PARK (P); automatic all-door unlock
when the transaxle is shifted into PARK (P).
Before your vehicle was shipped from the factory, it was
programmed to Mode 4. The mode to which the
vehicle was programmed may have been changed since
it left the factory. To determine the mode to which
your vehicle is programmed or to program your vehicle
to a different mode, see Vehicle Personalization on
page 2-43.
Disconnecting the vehicle's battery for up to a year will
not change any previously programmed modes.
Lockout Protection
To protect you from locking your key in the vehicle, this
feature stops the power door locks from locking when
the key is in the ignition and a door is open.
If a power lock switch is pressed when a door is open
and the key is in the ignition, both doors will lock
and then the driver's door will unlock. A chime will sound
continuously until both doors are closed.
Leaving Your Vehicle
If you are leaving the vehicle, take your keys, open your
door and set the locks from inside. Then get out and
close the door.
