Lockout Protection

This feature protects you from locking your key in the
vehicle when the key is in the ignition and a door
is open.
If the power lock switch is pressed when either the
driver's, passenger's, or rear door is open, all the doors
will lock and then the driver's door will unlock. This
feature does not include the side cargo door.

Leaving Your Vehicle

If you are leaving your vehicle, take your key, open your
door and set the locks from inside. Then get out and
close the door.
