Delayed Locking (If Equipped)
This feature lets the driver delay the actual locking of
the vehicle. When the power door lock switch is pressed
with the key removed from the ignition and the driver's
door open, a chime will sound three times to signal that
delayed locking is active. When all doors have been
closed, the doors will lock automatically after five
seconds. If any door is opened before this, the
-
five second timer will reset itself once all the doors have
been closed again.
Pressing the door lock switch twice within two seconds
will override this feature.
