System will not disarm with a manual unlock, eitherthrough the lock plunger located on the inside of the
door, or through a key in the driver's door key cylinder.

after you close all the doors.
REMOTE KEYLESS ENTRY
This system allows you to lock or unlock the doors,
liftgate, or activate the panic alarm from distances up to
about 23 feet (7 meters) using a hand held radio trans-
mitter. The transmitter need not be pointed at the vehicle
