Door Locks

Warning: Unlocked doors can be dangerous.

• Passengers, especially children, can easily open the doors and fall out of a moving vehicle. The doors can be unlocked and opened while the vehicle is moving. 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 seat 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 the vehicle. Locking the doors can help prevent this from happening.

To lock/unlock the doors from outside the vehicle:

• Press or on the Remote Keyless Entry (RKE) transmitter.
• Use Keyless Access.

To lock/unlock the doors from inside the vehicle:

• Press or on a power door lock switch.
• Pull the door handle once to unlock it. Pull the door handle again to unlatch it.
• Push down on the door lock knob on the top of the door to lock the door. Manually locking the driver door also automatically locks all other doors.

Keyless Access

The RKE transmitter must be within 1 m (3 ft) of the liftgate or door being opened. Push the button on the door to open.

Driver Door Key Lock Cylinder Access (In Case of Dead Battery)

To access the driver door key lock cylinder:

1. Insert the key into the slot on the bottom of the cap.

2. Lift the key upward to remove the cap.

3. Insert the key into the cylinder and turn to unlock.

To replace the cap:

1. Position the bottom edge of the cap under the lower edge of the metal piece (2). The tabs (3) attach to the metal piece (2) at the positions (1).

2. Rotate the cap upward and install into place.

3. Check that the cap is secure.

Free-Turning Locks

The door key lock cylinder turns freely when either the wrong key is used, or the correct key is not fully inserted. The free-turning door lock feature prevents the lock from being forced open. To reset the lock, turn it to the vertical position with the correct key fully inserted. Remove the key and insert it again. If this does not reset the lock, turn the key halfway around in the cylinder and repeat the reset procedure.
