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 key. To lock the door, turn the key toward the front of the vehicle. If you have power door locks, all the doors will lock. Insert the key in either front door and turn the key toward the rear of the vehicle to unlock the door. If your vehicle has power door locks, turn the key once to unlock the driver's door only. Turn the key back toward the center, then toward the rear again to unlock all the doors. Using the key in the passenger's door will also unlock all the doors. To lock the door from the inside, push down the button on the door. To unlock the door, pull up on the button. 2-4
