Central Door Unlocking System
If your vehicle has a theft-deterrent system, all doors
will unlock if the key is held in the outside key cylinder
unlock position for more than two seconds. The
doors will also unlock if the key is turned to the unlock
position twice in three seconds.
Power Door Locks
With power door locks, you
can lock or unlock all
doors on your vehicle
using either the driver's or
the front passenger's
power door lock switch.
Door Ajar Reminder
If your vehicle is equipped with the Driver Information
Center (DIC), and a door is not fully closed, the DIC will
display a DOOR AJAR message. See Driver Information
Center (DIC) on page 3-47.
Delayed Locking
This feature lets the driver delay the actual locking of
the doors. When the power door lock switch or the
remote keyless entry transmitter lock button is pressed
with the key removed from the ignition and the
driver's door open, a chime will sound three times to
signal that the lock delay mode 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 or the remote keyless
entry lock button a second time will override this feature.
