There are several ways to lock and unlock your vehicle. If your vehicle is equipped with keyless entry, see Remote Keyless Entry (RKE) System on page 103 for more information. From the outside, use your key. To lock the door from the inside, slide the manual lever on your door down. To unlock the door, slide the manual lever up. Power Door Locks Press the bottom side of the power door lock switch to lock all the doors at once. Press the top side of the power door lock switch to unlock all the doors at once. When a door is locked, the inside door handle will not work. Cargo Door Relocking This feature protects against having an unsecured side cargo door. If the side cargo door is open when the lock button is pressed on the door or the remote keyless entry transmitter, all doors will lock and then relock again after the cargo door is closed. If the cargo door is not closed within several minutes, the relock will not occur. 109
