Lockout Protection

This feature helps prevent you from locking the
doors while your key is in the ignition. Always
remember to take your key with you when exiting
your vehicle.
If the lock switch is pressed on the door that is
open and the key is in the ignition, all of the doors
will lock and then the driver's door will unlock.
A chime will sound continuously until all doors are
closed.
