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.

There are several ways to lock and unlock the vehicle.

Because the vehicle has the theft-deterrent system, the doors must be unlocked from the outside with the key or Remote Keyless Entry (RKE) transmitter to avoid setting off the alarm. If the windows are down and the doors are locked, do not reach in to manually unlock the vehicle because you will set off the alarm.

From the inside, use the manual lock levers located on the door panels near the windows.

Push down on the manual lock lever to lock the door. To unlock the door, pull up on the lever.
