Below is a picture of the inside of a 2010 Toyota Highlander dashboard and you can see the button that looks like a windshield. This button is the button for the Heated Windshield Wiper Park Area feature. When you press this button it turns on heat to the windshield and also to the side mirrors. You must know if you have this feature when replacing your windshield because this vehicle comes with this feature and also without this feature. If you are not sure if your vehicle has this feature first look for this button and if you don't see it you don't have it. Another way to find out is to take your VIN (Vehicle Identification Number) and contact your local dealership parts department and then they will be able to tell you if you have the feature.
