We have added front window tinting and windshield tinting to our Venza. The front windows seem to not have any tinting at all, which was surprising to us. It looks like the rears are tinted at about 20%, so we added a 35% tint to our front windows. This will help with both the heat and the UV for front driver and passenger. We also added a very light front windshield tint. The windshield is tinted at 70%, so it is just a very light shade to assist with heat inside the car, UV impact on the inside, and makes driving during bright days a little easier on the eyes. We were a little concerned about how the windshield tinting would impact the heads up display, but seems like there is no issue there.
