WARNING!
Unlocked doors can be dangerous.
• Passengers, especially children, can easily open the doors and fall out of a moving vehicle. 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 slowing or stopping the vehicle. Lock the doors to help prevent this from happening.

To lock and unlock the doors from the outside, use the Remote Keyless Entry (RKE) transmitter or the key.

To lock the doors from inside, use the power door lock switch or door lock knob. To unlock the doors, use the power door lock switch or pull once on the door handle to unlock it, and a second time to open it.

Manually locking the driver door also automatically locks all other doors.
