Door Locks CAUTION: Unlocked doors can be dangerous. D Passengers -- especially children -- can easily open the doors and fall out of a moving vehicle. When a door is locked, the handle won't open it. You increase the chance of being thrown out of the vehicle in a crash if the doors aren't locked. So, wear safety belts properly and lock the doors whenever you drive. D Young children who get into unlocked vehicles may be unable to get out. A child can be overcome by extreme heat and can suffer permanent injuries or even death from heat stroke. Always lock your vehicle whenever you leave it. D Outsiders can easily enter through an unlocked door when you slow down or stop your vehicle. Locking your doors can help prevent this from happening. There are several ways to lock and unlock your vehicle. From the outside, use your key or remote keyless entry transmitter (if equipped). From the inside, use the manual or power door locks. To unlock either front door from the outside with the key, insert the key and turn it toward the front of the vehicle. To lock either front door from the outside with your key, insert the key and turn it toward the rear of the vehicle. To lock the door from the inside, push the manual lock lever forward. To unlock the door, pull the lever rearward. 2-6
