Test Drive: Nissan updates, beautifies Altima for 2013: Nissan has some great usability in the new Altima.
Altima’s tire pressure display shows the pressure in each tire, unlike some cars’ idiot lights that come on when a tire’s low but give you no clue which one to check. Nissan designed the system to help you fill the tire. Air up and the car’s flashers come on to show air is going in. The horn chirps when the tire’s full.
