Caution: Unlocked doors can be dangerous.

   •  Passengers, especially children, can easily open the doors and fall out of a moving vehicle. When a door is locked, the handle will not open it. The chance of being thrown out of the vehicle in a crash is increased if the doors are not locked. So, all passengers should wear safety belts properly and the doors should be locked whenever the vehicle is driven.
   • 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 the vehicle whenever leaving it.
   • 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.

To lock and unlock your vehicle from the outside, use your key or the Remote Keyless Entry transmitter, if equipped. See Remote Keyless Entry (RKE) System Operation for more information.

Open the driver door, on vehicles with power door locks, by turning the key in the lock toward the rear of the vehicle.

Turn the key back toward the center and toward the rear again, within three seconds, to unlock all of the doors. Use the key in the passenger door to also unlock all of the doors.

Lock a door by turning the key toward the front of the vehicle. If you have power door locks, all the doors will lock.

To manually lock or unlock the door from the inside, move the lever on the door forward or rearward. The driver and front passenger door open from the inside while locked.

With manual locks, the key must be used to lock and unlock the liftgate.
