How To: Remote A/C Access in a 2010 Prius

Prius models equipped with a tilt/slide sunroof have a remote control button on smart keys for the remote air conditioning system. Before leaving the vehicle, make sure the headlights are off or set to automatic. Close all windows and check the temperature setting of the air conditioning system. When you return to the Prius, press the AC remote control button on the smart key remote to activate the air conditioning system. The cabin will cool down to the set temperature without starting the engine. The system will work for 3 minutes. or until you open the door, whichever comes first.
