Power Window Control: Power window control can be provided by
one of two systems. The firsts system provides control that will roll up
two windows automatically when the system is armed, or roll two win-
dows down by using the remote. The second system will roll two win-
dows both up and down. This second system also provides one touch
switch operation.
Progressive Door Unlocking: For added security, your system can be
configured to unlock the driver's door only, leaving the passenger doors
locked. Pressing the unlock button an additional time will unlock the
passenger doors. This option requires additional parts and labor.
