This feature allows the locking of the vehicle to be

for approximately five seconds.
When the delayed locking feature is enabled, it may be
activated when the key is out of the ignition by doing
one of the following:

Pressing the driver's door power lock switch
one time while the driver's door is open.
•
Pressing the passenger's door power lock switch
one time while the passenger's door is open.
•
Pressing the lock button on the remote keyless
entry transmitter one time while any door is open.
Two chimes will sound to signal that delayed locking
is active.
The doors may be locked immediately by repeating
one of the above actions more than one time.
If a door remains open, without any other door
being opened or closed, the vehicle will lock after
approximately 45 seconds.
