More Power to Power Windows. Open, close and vent the car's power windows using the G5 security system remote control. SmartWindows also adds extra features inside the vehicle: one tap fully open, one tap fully closed. Tap the switch during roll-up and roll-down to instantly stop the window. Vent opening is selectable via the CliffNet Wizard, and can be vented repeatedly after remote arming. The SmartWindows Safety Stop feature halts window movement if there is an obstruction.
