Lockout Protection

If the key is in the ignition and the power door lock
switch is used to lock the doors, all doors will lock
and then the driver's door will unlock. It is always
recommended that you remove the ignition key
when locking your vehicle.
The lockout protection feature can be overridden
by holding the power door lock switch for
three seconds or longer.
