Often it is a feature that is not thought about until it is needed, but windshield wiper function matters to drivers, especially in rainy and cold climates. Nissan took notice with two new changes to the 2013 Nissan Altima.
Nearly 30 states require drivers' car headlights be turned on in rain or heavy fog, and that's part of the motivation behind the new Nissan Altima's enhanced headlight feature. Automatic headlights respond to light conditions outside. If your wipers are on, so are the headlights. They automatically turn on after four wiper cycles.
