Door Locks CAUTION: Unlocked doors can be dangerous. Passengers -- especially children -- can easily open the doors and fall out. When a door is locked, the inside handle won't open it. Outsiders can easily enter through an unlocked door when you slow down or stop your vehicle. This may not be so obvious: You increase the chance of being thrown out of the vehicle in a crash if the doors aren't locked. Wear safety belts properly, lock your doors, and you will be far better off whenever you drive your vehicle. There are several ways to lock and unlock your vehicle. From the outside, use your door key. If your vehicle has the content theft-deterrent/alarm system and it is armed, unlocking and opening a door this way will set off the alarm after eight seconds unless the ignition key is inserted into the ignition. See "Content Theft-Deterrent/Alarm System" in the Index. To lock the door from the inside, slide the lock control located on the door rearward. To unlock the door, slide the lock control located on the door forward. 2-4
