Rear Door Security Locks
Your vehicle has rear door security locks. These
prevent passengers from opening the rear doors from
the inside.
The rear door security
locks are located on the
inside edge of each
rear door. The rear doors
must be open to access
them. The label showing
lock and unlock positions is
located near the lock.
To set the locks, do the following:
1. Insert the key into the security lock slot and turn it
so the slot is in the horizontal position.
2. Close the door.
When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door using the Remote Keyless Entry
(RKE) or Keyless Access System transmitter, if
the vehicle has one, the power door lock switch, or
the rear door manual lock.
2. Open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
