You can lock all doors and the liftgate from the inside by pressing the rear of the power lock switch on either front door. With the content theft-deterrent system, the power door lock switch may cause the system to arm. See Content Theft-Deterrent on page 2-26 for more details. If the liftgate has been unlocked with the power door locks, you will not need the key to open it. Squeeze the handle located above the license plate to open the liftgate. This is also true if you use the remote keyless entry transmitter. See Remote Keyless Entry System on page 2-4. Last Door Closed Locking The last door closed locking feature will delay the power locking of the doors and liftgate for up to five seconds after exiting the vehicle, when the power door lock switch or the lock button on the remote keyless entry transmitter is used to lock your vehicle. To cancel this delay, press the power door lock switch or the lock button on the remote keyless entry transmitter a second time immediately. If any door or the liftgate is open when locking the vehicle, three chimes will be heard signaling that last door closed locking is being used. Five seconds after the last door is closed, all of the doors will lock. If the ignition is in RUN or ACCESSORY, this feature will not lock the doors. To turn the last door closed locking feature off or on, see Vehicle Personalization on page 2-57. 2-11
