Sliding Door Security Lock n I I\ d Your vehicle may have this feature. A sliding door security lock helps to prevent young children or other passengers from opening the sliding door using the inside door handle. There are two labels on your vehicle to remind you that you have this feature. One can be seen from the outside on your sliding door. It is located near the bottom of the door glass, toward the front of the door. The other label is located on the front of the sliding door, near the security door lock. This feature prevents passengers from opening the sliding side door from the inside. To use this feature, do the following: 1. Move the lever all the way up. 2. Close the door. To open the sliding side door while the security lock is engaged, unlock the door and open it from the outside. The security door lock is located near the front of the sliding door. If you don't cancel the security lock feature, adults or older children who ride in the rear won't be able to open the sliding door from the inside. You should let adults and older children know how the security door lock works, and how to cancel the lock. 2-1 1
