You have three actions possible once Delayed Locking is activated: Delayed Locking Delayed Locking allows the doors to locked while be passengers are exiting the vehicle. This featurealso provides a brief time period after all the doors are closed, but before the doors are locked, in which the doors may be reopened. Delayed Locking is user programmable for the enabling or disabling of the feature. Delayed Locking is activated when a door lock switch is pressed while the key is not in the vehicle's ignition, and a door is open. The door lock switch may be either the lock switch on the door or thelock button on the remote keyless entry transmitter (see "Remote Keyless Entry" later in this section for more details). The doors do not lock when the lock switch is pressed, but instead, three chimes are heard. These chimes indicate that the Delayed Locking feature has been activated. 1. Cancel the Delayed Locking by pressing the unlock switch or by fully inserting the key in the ignition. 2. Override the Delayed Locking feature and lock the doors immediately by pressing the lock switch a second time. 3. Let the Delayed Locking feature complete the locking of the vehicle.

During this five second period, any door may be reopened, at which time the three possible actions shown above are again available. 2-8
